INTERNATIONAL CONFERENCE ON SCIENCE AND TECHNOLOGY (ICST) 2019

Remarks from Rector of Universitas Pembangunan Nasional Veteran Jawa Timur

Assalamualaikum Wr Wb.

On behalf of The Rector of University of Pembangunan Nasional Veteran Jawa Timur, I would like to extend my warmest welcome to all participants, delegates from all over the world, and keynote speakers to the IJSCT 2019. Welcome to Surabaya, at Sheraton Hotel & Tower. Welcome to Surabaya, one of the biggest city in Indonesia, and called a heroes city. This city holds many stories of struggles against invaders. No wonder that in Surabaya, we can find many unique architectural buildings and historical heritage. Welcome also to our University, Belanegara Campus. Our campus was characterized by specific character building of our student. We develop a patriotic soul and patriotism in our learning process.

Taking place every year, the theme of this year’s conference is “Industrial 4.0: The Opportunities and Challenges In Elevating Local Resources Contribute To Develop A Better World”. This theme is intended to promote the relationship between the manufacturing industry and the local resources. In the Industry 4.0 era, the ‘real’ and the ‘virtual’ world are to be connected to what is known as cyber-physical production systems. As a result, the traditional manufacturing processes are undergoing an enormous transformation which will change the way companies approach manufacturing, and it will cause a polarization of the labor force. Industry 4.0 also will have the potency to change the nature of jobs, education and skill requirement; because it requires the increasing of technical competencies. The use of rapid technology will contribute to increased efficiency; and will affect productivity, competitiveness, and employment.

We are very pleased to welcome you in the proceedings book of the IJCST 2019. These proceedings are one of the continuations for the conference. Based on these papers, hopefully, more collaborations can be initiated or should be followed up between us.

INTERNATIONAL CONFERENCE ON SCIENCE AND TECHNOLOGY (ICST) 2019

Remarks from Rector of Universitas Negeri Manado

Salam Sejahtera bagi kita sekalian, Assalamu’alaikum warahmatullahi wabarakatuuh., Om Swastiastu, Namo Buddhaya, salam kebajikan First of all, allow me as the Chancellor of to give Praise and Gratitude to the presence of Almighty God because of His grace and participation so that the 2019 International Joint Conference on Science and Technology (Surabaya) can run well. In the current 4.0 Industrial Revolution era, innovation takes place very quickly with competition in various fields which are increasingly stringent, including in the world of Higher Education. To be able to advance and compete globally, inevitably Higher Education must continue to encourage and support the development of Education and Learning Activities, Community Service and Innovative Research for lecturers and students. The results of the research should not only be stored and deposited in the Higher Education environment but must be widely disseminated so that it can be known by all interested parties. Moreover, based on Permenristekdikti No.20 of 2017, Lecturers with functional positions as Professor and Head Lecturer must conduct Scientific Publications both nationally and internationally. I see the 2019 IJCST to be one of the appropriate venues for universities to disseminate our ideas and research results, as a form of public accountability, fulfilment of the conditions of publication obligations, and active participation in improving the quality of tertiary institutions, because the articles presented at this conference will be published in the form of CPCI indexed proceedings (Clarivate Analytics / Thomson Reuters / Web of Science). On this occasion, I also want to give high appreciation to the collaboration of the Higher Education Consortium in the implementation of the 2019 IJCST which has proven to encourage us to support each other, share information, reference, experience and even technology in conducting international conference events, so that we can move forward together and complement each other in increasing the capacity of each university.

INTERNATIONAL CONFERENCE ON SCIENCE AND TECHNOLOGY (ICST) 2019

Remarks from Rector of Musamus University

Honorable the Chancellors, the Deans of the Consortium Members, the keynote speakers, the authors (lecturers and researchers), the committees and all participants.

Shalom and best wishes.

Praise be to the Almighty God for blessing and guiding us into this special moment, the International Joint Conference on Science and Technology (IJCST) 2019.

It is such an honor to be and take a part in this consortium, the 2nd IJCST 2019 organized by the University of Trunojoyo Madura. We realize that this conference is the right place for researchers in the fields of science and technology, social and humanities to improve the quantity and quality of their research publications, beside their obligation to carry out the Tri Dharma of higher education. Each lecturer is required to publish the results of his/her research in either national/international journals or in national / international conferences. This is absolutely important for improving lecturers’ achievement and influencing university ranking.

We realize that to keep existing in publications in either international journals or conferences is not easy, especially for the new state universities such as Musamus University. Therefore, it is extremely significant to make an agreement in consortium to conduct international seminars regularly.

Musamus University is committed to increase the quantity and quality of lecturer publications to improve university rankings and as a capital for lecturers to improve academic positions. Therefore, Musamus University is very proud to be accepted and for the second time taking a part in the Higher Education consortium at the International Joint Conference on Science and Technology to increase the number of lecturer publications and university rankings. Hopefully, the implementation of IJCST 2019 in Surabaya can run well and offer all members and participants of this consortium the plentiful benefits.

XV

INTERNATIONAL CONFERENCE ON SCIENCE AND TECHNOLOGY (ICST) 2019

We hope this conference will be a great and successful event not only as an opportunity to share knowledge and experiences but also as a start of good cooperation and friendship among consortium members.

As closing, we would like to extend gratitude to all delegates for their full cooperation and contribution in IJCST 2019 and the organizers of the University of Trunojoyo for opening opportunities and working hard for the convening and success of this conference.

Finally, allow me on behalf of Musamus University to wish you a fruitful and pleasant international conference.

Thank you

Remarks from Rector of Universitas Pembangunan Nasional Veteran Jakarta

“The measure of intelligence is the ability to change”(Albert Einstein)

Intelligence (intelligence) is a person's ability to think logically, communicate, learn, know, understand, remember, have planned, think creatively and be able to solve problems. Learn from the experience and also be able to adapt to the environment. Intelligence is synonymous with the tertiary environment, lecturers who have the task of doing higher education, education, and research and community service.

For the performance of the field of research, especially in the Ministry of Research, Technology and Higher Education currently in the spotlight, Mr. Jokowi - President of the Republic of Indonesia. On the occasion of opening the 2018 Plenary Cabinet meeting, Mr. Jokowi once questioned the benefits of a research fund of Rp. 24.9 Trillion in various ministries/institutions that have no impact on the resolution of community problems.

(https://bisnis.tempo.co/read/1077794/jokowi-question-results-riset-with- budget-Rp-249trillion )

The International Conference on Science and Technology (ICST) with the theme "Industrial Revolution 4.0: The opportunities and challenges in elevating local resources contribute to developing a better world" can be used as a momentum for us to answer the President's turmoil by producing research that is not only just stop in publication to fulfil the task of research darma alone but to continue to be research that is able to answer problems in society, especially in the digital era, the era of technology, the era of the industrial revolution 4.0.

This conference was held by involving 12 universities, this collaboration will be a driving force for quality research, and each university has its advantages in the direction of research which can then be joined by experts

XVII

INTERNATIONAL CONFERENCE ON SCIENCE AND TECHNOLOGY (ICST) 2019 in other universities. In the current competitive era of collaboration, resource mobilization is a must. Nobody can do something individually at this time.

UPNVJ hopes that after this conference the lecturers will follow up on these studies by pioneering, building cooperation with the industrial world so that the downstream is achieved, then the researchers will communicate with each other intensely to follow up on this activity by conducting joint research.

Finally, Congratulations and Success for the International Conference on Science and Technology (ICCT) and thank you UPNVJ for the opportunity to participate in this activity.

Coming together is a beginning Staying together is progress Working together is a success (Henry Ford)

Network configuration optimization for wireless local-area network with three Raspberry Pi access-points under concurrent communications

Nobuo Funabiki

Okayama University, Japan

[email protected]

Abstract- Nowadays, the wireless local-area network (WLAN) has been deployed around the world as an inexpensive and flexible access network to the Internet. Because WLAN does not need a cable to connect a host or a mobile device with an access-point (AP), it has several advantages over a wired LAN such as low installation and management costs, easy host relocations, and flexible service areas. In WLAN, 11 or 13 partially overlapping channels (POCs) are available at the popular 2.4GHz. Each POC has the 20MHz frequency width, and the frequency gap between two adjacent channels is only 5MHz. Thus, one POC is interfered with at least three neighbor channels. Currently, the IEEE 802.11n protocol is common in WLAN, which adopts the high-speed wireless communication technologies, including the channel bonding (CB), the multiple- input-multiple-output (MIMO), and the frame aggregation. Among them, CB enhances the speed by bonding two channels into one. Thus, when multiple APs in a network field are concurrently communicating, they are always interfered with each other. The throughput feature becomes different from the single communication. To realize a low-cost WLAN, we have studied the use of Raspberry Pi for the software access-point (AP) in the IEEE 802.11n WLAN. This device has become popular around the world as a low-cost, small, and powerful computing one. Since the built-in wireless network interface card (NIC) fails to support CB, we have configured CB using an external NIC adapter and investigated the performance. Besides, we have studied the two-step throughput

INTERNATIONAL CONFERENCE ON SCIENCE AND TECHNOLOGY (ICST) 2019 estimation model to estimate the throughput or data transmission speed of a WLAN link for the single communication. The first step estimates the receiving signal strength (RSS) at the receiver by using the log-distance path loss model. The second step calculates the throughput from that RSS using the sigmoid function. Both functions have several parameters affecting the estimation accuracy. Thus, their values are optimized by the parameter optimization tool. In this talk, we introduce our latest studies of the network configuration optimization and its related topics for the IEEE 802.11n WLAN using three Raspberry Pi APs with 11 POCs. First, we present throughput measurement results in concurrent communications of three Raspberry Pi APs with/without using CB. Second, we extend the throughput estimation model by introducing the reduction factor to consider interferences among them. Third, we propose the network configuration optimization algorithm for WLAN with three Raspberry Pi APs using the extended throughput estimation model. The network configuration signifies the adoption of CB or non-CB, the channel assignment, and the host associations for each AP. Finally, we evaluate the algorithm through simulations and testbed experiments.

Abstract - ASSAB 618S steel is a type of medium carbon steel that is often used as a machining tool for the petroleum industry. Based on the observation, it does not work optimally due to high acidity. As a result, there is corruption in the machining tool. In this study, an electroplating process will be carried out as a way to overcome corrosion in machining made of ASSAB 618S steel. The variables involved independent variables, dependent variables, and control variables. The independent variable is the temperature of the electrolyte solution with variations of 55oC to 70oC. The dependent variable is the corrosion rate on the results of electroplating hard chrome coating. The controlled variable is the distance of electrodes with variations of 3 and 9 cm. The data obtained showed that the highest corrosion rate was obtained from the temperature variation of the electrolyte solution of 55 degrees Celsius and the electrode distance of 9 cm, while the lowest corrosion rate was obtained at a temperature variation of 70 degrees Celsius electrolyte and 3 cm electrode distance. The data is in accordance with the theory of corrosion rate that is smaller better. It means that the smaller the corrosion rate, the better the corrosion resistance. Based on the results of this study, it can be concluded that the temperature of the electrolyte solution, the distance of the electrode, and between both interactions give an influence on the corrosion rate of the electroplating hard chrome coating.

Abstract - A maze is a collection of walls and spaces arranged in such a way that they form a path/paths usually connecting an entry point to a goal. There are various kinds of maze solving algorithms. These methods are used in practice to help navigate an autonomous system to find a path within maze to find a target such as an exit point, special item, or location to the next level. This research explored two maze solving algorithms: Wall Follower and Dead End Filler. Experiments were conducted to measure the time needed for each algorithm in solving 50 perfect mazes of various sizes. The test mazes were generated dynamically using Recursive Backtracker method. The result showed that Wall Follower algorithm is faster than Dead End Filler algorithm. The difference is slightly under twice as fast; for example in solving 800 x 800 cell mazes, the former required an average time of 98.74 milliseconds while the later needed 171.94 milliseconds.

Abstract - Study on robot navigation has been progressing significantly. However, research of autonomous navigation is still lacking in environments with changing layout. For supporting robot navigation system, rotational and translational motion estimation need to be improved. Low cost sensor such as Kinect can be used as alternative to laser to percept changing in the vicinity of robot. There is still problem in developing motion estimation using Kinect. Narrowness in the sensor field of view limits its ability to track robot motion. This problem emerges specially in translational motion estimation. This paper aims to develop a simple approach based on RGB-D data for translational motion estimation of a Kinect sensor. RGB-D data consist of RGB and Depth images. In previous research, camera was positioned in the direction of longitudinal translational motion. This paper differs from previous works in terms of sensor setting that is placed in the direction of lateral translation movements. Point features are matched between pairs of RGB frame to get interesting pixels. Depth image provides distance information for these pixels in synchronization with feature tracking process. Law of cosines is then applied to these depth pixels to get position translation. Results show that our approach have decreased RMSE to 0.0382 meter better than previous works. In the future research, this translational motion estimation system will be implemented in mobile robot system to support navigation function.

1,4Information system, Engineering Faculty, Trunojoyo University of Madura 2,3Faculty of Science and Technology, of Surabaya Abstract - The quality of agricultural land is an important factor for corn farmers in Madura. To overcome this problem, biopesticides can be used in the form of bacteria that can kill plant pest organisms (OPT). Bacillus thuringiensis is one of the bacteria that can produce protein crystals that are insect killers (insecticides) when undergoing a sporulation process. By studying this identification, it is expected that farmers can analyse the use of pesticides and replace them with bio- pesticides that are more environmentally friendly. In this study, an image processing approach was used to identify the presence of biopesticide bacteria. At the pre-processing stage, the stages of a culture of bacterial colonies were carried out on Mac Conkey media, followed by repairs to the results of image morphology. Fuzzy Clustering level set is one of the methods used in the image segmentation process. The results of form extraction are then used in the training process to determine the type of bacteria in the sample. This method makes identification of agricultural land easier, faster and costs less. The result is that in processing 100 training data and 25 data testing using Bacilli bacteria with 9 bacterial morphological attributes and 2 identification classes the accuracy value of the Random Forest decision tree was 91%.

Abstract - A restaurant menu recommendation system is becoming a necessity following the trend of eating out at the restaurants. The task of such a system is to generate a top-Nlist of menus that may be of interest to a customer, in which the customer previous rating behavior is used as the learning model. In this paper, we apply the SVD (Singular Vector Decomposition) latent factor model as the learning technique of the recommendation system. Beforehand, we implement the mean imputation technique to fill in the missing rating entries so that SVD can also deal with the new customer that has no rating record in the system. Evaluation on a real- world restaurant menu recommendation dataset shows that our recommendation system is able to generate a top-10 list of menu recommendations to a target customer and that the results of the low-rank approximation using SVD are comparable with that of the full-rank.

Abstract - The aimof this study is to remove the influence of weather factors in order to improve the visual effects of the image and provide benefit to post- processing. Images captured in hazy or foggy weather conditions can be seriously degraded by scattering of atmospheric particles, which reduces the contrast, changes the color, and makes the object features difficult to identify by human vision and by some outdoor computer vision systems. Therefore image dehazing is an important issue and has been widely researched in the field of computer vision. Image haze removal based on dark channel prior can perform very well. But it didn't deal with sky region and brightness objects because dark channel prior is not established in these regions. To solve the problem and enhance the contrast, this paper propose to restored the hazy image by adding the contrast limited adaptive histogram equalization. With the contrast limited adaptive histogram equalization method, the results of the dark channel prior results can be contrasted so that the image becomes clearer and more specific. Experimental results showed that such method is MSE 0.256 is equal to PSNR of 54,043 With this research, it is expected that a clean image after processing can provide maximum information to humans.

Abstract - Recently, computer vision research results have supported many sectors to assist and solve problems. One of branch of the computer vision fields is biometric system. Many modalities have been implemented to depict the human characteristics. Face is one of the modalities that has been employed to recognize the human. A crucial problem of the face recognition is high dimensionality. The problem would impact on the computational performance, and even it could cause the process failure. Feature extraction is the solution to reduce the dimensionality. However, many cases have shown that feature extraction could fail as singularity problem. In this research, we proposed the improvement of the fisherface algorithm to solve the singularity problem. We have modified the singularity covariance matrix so that the matrix can be further handled and processed.The purpose of the paper is to improve the performance of the fisherface algorithm. We have verified our proposed algorithm by using the Olivetty Research Laboratory face image. We applied 7-cross validations to evaluate our proposed algorithm, the evaluation results achieved more than 92% accuracy.

Abstract - Content Based Image Retrieval (CBIR) is a process to search for an image based on the content or features that are inside. Nowadays, many image retrieval applications have been made to meet the needs, so this application can provide convenience in terms of the introduction and search for an image. In this research, we used 10 different objects as image retrieval consists of Bicycle, Cow, Flower,Frangipani, Grape, Horse, Lovebird, Orange, Strawberry, Tree.These objects can be expressed in 10 classes. Our aim using these objects is viewed from the color of every object and the object of a different kind. From that point of view we built a CBIR system by utilizing the main features of the object (image). The main feature is the color feature. In this research, the main process is the extraction of color features with the color histogram and color moments. So in this research it will produce feature extraction by measuring the similarity in the library image. This measurement is done by calculating the closest distance using the euclidean distance method. The data library used in this research is 10 pieces of data, the test data is 50 pieces with 5 pieces for each of these classes. After testing using data and methods described above, the results of accuracy are obtained that the application of the color moments method gets better results than the color histogram method.

Abstract - Water is vital for all living things on the earth, so there must be an effort to save water. One effort to save on water use is by making automatic water taps. Automatic water taps which are meant here are water taps on the sink and also water taps for ablution. The working principle of the two taps is the same, that is, the water tap will open if there is an object (human) detected in front of the water tap. In this automatic faucet system the arduino mega 2560 microcontroller is used as data processor obtained from ultrasonic sensors and Passive Infrared Receiver (PIR) sensors. The two sensors are used interchangeably and the results are compared to determine the difference in response time. Based on the tests that have been done, it is found that the time needed for the ultrasonic sensor to open or close the water tap is faster than the PIR sensor. When opening the tap the time needed by the two sensors is almost the same, which is only 4ms difference. Whereas when closing the tap the time needed for the PIR sensor is much longer, which is more than 4s. This is because the process of returning the sensor to return to normal is not detecting the presence of humans or in other words the sensor does not detect infrared rays tend to require a longer time. As for the ultrasonic sensor because what is detected is the distance, so the object moves from the front of the tap then the distance detected will change immediately so that the tap will immediately close again.

Abstract - Madura Island is one of the largest peanut producers in Indonesia, but the production of peanuts produced on average is still relatively low, ranging from 0.7 to 1.5 tons / ha. The low yield of peanuts is caused by several factors, one of which is unstable environmental conditions and pests that attack plants. Efforts to increase production can be done by monitoring / checking plants. Monitoring is usually done directly but it is not effective, people often have other jobs besides monitoring so they can forget about the plants. Based on this problem a monitoring system and control of peanut growth in a web-based plant house were designed. This system will carry out monitoring in the form of real time video and the detection of temperature and humidity sensors to stabilize the conditions in the plant house based on conditions of temperature and soil moisture. In addition to monitoring this system provides 2 control modes namely automatic control and manual control to control watering solenoids and heating lights. The results of designing a monitoring and control system obtained data that is real time video capable of monitoring with speeds of 110 kb / s to 420 kb / s, sending sensor monitoring data no later than 1 second from the detected temperature changes, manual controls running according to the command on / off and not affected by environmental conditions day and night, automatic controls run in accordance with the conditions set based on readings on sensors of temperature and soil moisture, ambient temperature affects the level of soil moisture and operation of the web can be accessed from different laptops but only on 1 network and web can only be accessed by someone who has an ID.

Abstract - A vehicle is a transportation that is widely used by humans as transportation for daily activities. Vehicles generally use mechanical brakes to do braking, these mechanical brakes have a system that requires friction forces to produce a slowdown in the vehicle. The frictional forces carried out will make erosion of the mechanical brake pads and the need to periodically replace the bearings. In this study discussed the design and manufacture of braking systems using electric brakes to support the performance of mechanical brakes. Electric brakes that have advantages in the media used compared to mechanical brakes, namely electric brakes do not require friction media to slow down, but electric brakes use four aluminum plates as magnetic force media, while coils or windings with the inner core will produce electromagnetic force as an actuator braking. The braking system that is carried out will maintain the speed according to the setpoint value of 5100 rpm. This electromagnetic braking results in a maximum braking of 500 rpm and takes between 9 and 15 seconds to reach the steady state position.

Abstract - The manually scheduling system is considered less effective and efficient because it requires a long time. Problems will become more complex if the number of components or data used is increasing. The schedule is expected not only not to experience clashes, but also to adjust to some limitations that must be met. Genetic Algorithm is one of the heuristic search algorithms that are very well used in solving optimization problems. The problem of scheduling genetic algorithms is considered to have good performance in finding the optimal solution. Genetic Algorithms implement an evolutionary process by randomly producing chromosomes from each population These chromosomes produce a solution to the problem raised, namely scheduling subjects. The conclusion of this study is to be able to arrange the schedule of subjects efficiently, by overcoming obstacles such as clashing schedules without eliminating the constraints that must be met.

Abstract - Fluctuations in crude oil prices can affect a country's economic policies. The movement of crude oil prices tends to be nonlinear and non- stationary. One forecasting method that is intended to accommodate these traits is forecasting that integrates empirical mode decomposition (EEMD) ensemble methods based on artificial neural networks and genetic algorithms. In the EEMD method, a white noise signal is added to compensate for the mixture mode that can be formed. Each IMF and residue generated in the decomposition process are used as input to a feedforward neural network (FNN) artificial neural network to obtain forecasting models from each IMF and residue. The genetic algorithm is integrated with the FNN to avoid overfitting, the formation of local optima solutions, and the sensitivity of the selection of FNN parameters. The data in this study uses West Texas Intermediate (WTI) and Brent oil prices. The results of the performance comparison trials for several combination forecasting methods can be concluded that the forecasting results that integrate the EEMD method with JST-GA provide better results compared to the forecasting method that integrates EMD with ANN and EEMD with ANN. The forecasting method developed in this study resulted in forecasting with RMSE / Dstat values of 0.0257 / 61.5936% and 0.0270 / 72.0930% respectively for daily and monthly data from WTI oil types; and the RMSE / Dstat value of 0.0229 / 58.8128% and 0.0300 / 81.5789% respectively for daily and monthly data from the type of Brent oil.

Abstract - Text File Services is still an option for sending a message, the visible difference between Text File Services and other services besides the file size of sending messages is the security level. In Instant Messenger there are features to secure conversations with various Cryptograph methods, while Text File Services does not have that feature. Therefore made Text File Services with additional features Cryptograph. Cryptograph method used is the RSA algorithm. The RSA algorithm makes the plaintext increase in the number of characters, so the Compression feature needs to be added to suppress the increase in the number of characters. Shannon Fano is a Compression symbol wise algorithm where each character that is compressed is converted into a new binary code. This compression is intended to reduce the number of Encryption result characters. The results of this study obtained information that the RSA and Shannon Fano methods can be implemented in the text file service, with the longer key being used the longer the process of decryption of messages with the average value of the avalanche effect ciphertext and the result of Compression is relatively the same. The key length used for the possibility of Brute Force is positively correlated with an average Test Compression Ratio of 1.41 and space-saving of 29.37%.

Abstract - Stock market prediction is both attracting and challenging. The successful of stock price prediction will give financial benefit, therefore, it has attracted many researchers and practitioners since long time ago. One of stock prediction performance measurement is the accuracy. There are many methods for measuring the accuracy, ranging from simple to sophisticated mathematical formulation. This article describes some of those methods. MAPE is the most popular accuracy measure for forecasting since it is intuitive, easy to be interpreted and can be applied to measure the forecasting accuracy for both individual item and across item groups. However, the MAPE has shortcomings. First, the value of MAPE will be undefined if one or more of the actual data are zero. Second, MAPE is very sensitive to outlier data. Third, equal errors above the actual value result in a greater percentage error than those below the actual value. Finally, using the MAPE for forecast methods comparison will lead to a systematically under-forecast result. Even with its shortcomings, MAPE is preferred for the forecasting accuracy method due to its applicability, interpretability and reliability. Thus, it is better to look for ways of correcting the drawbacks of MAPE rather than searching for alternative measures which are less desirable than MAPE. This paper proposes a modified MAPE using moving average of the actual data (MAPEMA) to reduce the drawbacks of MAPE. The result shows that the use of MAPEMA can reduce the problems of using MAPE.

Abstract - Human body naturally contains complex electrical signals ranging from the mechanism of the brain, heart, and muscles. Electromyography (EMG) is the development of biomedical engineering devices used to record electrical signal activity produced by muscles. The signal produced by the muscle has a very small amplitude, therefore, an amplifier circuit is required to read the signal using microcontroller. In this study, EMG signal amplification was carried out periodically to reduce errors that might occur if only charged to one signal amplifier. Signal reading was performed by conducting 5 different basic hand movements. Muscle signal activity during relaxed conditions had an amplitude of 0.05 V. Moreover, it conveyed an amplitude of 0.27 V up to 2.62 V with a signal gain of 10.350 when the muscle did different movements. The K-NN algorithm was used to classify EMG signals and determined the hand motion output used as a basic electronic control system. Results showed success rate of 88%. Failures when carrying out basic electronic control was due to the signal classification processes that had not met the parameters and the signal amplitude that was almost similar to another signal.

Abstract - Diversity is the main advantage of MIMO (Multi Input Multi Ouput) radar that improves radar capabilities to identify target parameters, including the maximum number of targets that can be detected, the target angle, range, etc. While the weakness of MIMO radar is the absence of coherent gain, it is the main advantage of the phased-array radar. Combining advantages of both multi- antenna structures, Phased-MIMO radar has been previously proposed. On phased-MIMO radar, the antenna is arranged into sub-arrays, each of which is composed of several antennas with same phase, thereby producing coherent gain. Diversity is produced by the use of multiple sub-arrays which allows overlapping of the antennas and uses orthogonal waveforms on different sub-arrays. This paper reports on the phased-MIMO radar capability to identify target parameters, namely, the maximum number of targets that can be detected by radar and the target angle that can be detected by radar.

Abstract - In production process, quality is directly affected by the degradation of the production machine. Information of products quality may be used as feedback to determine the maintenance policy. As far as is known, research on integration of quality and maintenance widely used quality control with 100% inspection. Many literatures mentioned that sampling inspection is cheaper and easier to be performed than 100% inspection. With the same level of protection, the variable acceptance sampling requires fewer samples and provide more information about the manufacturing process than the attribute data. This paper attempt to integrate variable acceptance sampling and maintenance policy. The variable acceptance sampling model developed based on exact sampling distribution approach under Cpk capability index. If the lot is rejected, 100% inspection will be performed and Cpk will be estimated. The estimated Cpk resulted minimum cost rate will be consider as the treshold for conducting PM.

Abstract - The higher Internet use also affects the level of information security in the digital world. Nowadays, many users send private messages or even secret messages through the Internet. This has an impact on the increasing number of illegal people who try to see and even change the information for personal gain. There is a solution to this problem by inserting a secret message in a file such as images, audio, or video. To increase the level of security, secret messages are encrypted first using cryptographic techniques. In this paper we propose a method for developing key generation in audio steganography techniques using the AES (Advanced Encryption Standard) algorithm. We use additional parameters to create the AES key, i.e. the user's identity. The user's identity is entered into the key table which is then randomly selected by the system when the user wants to get the key. There is a combination process and hash function to add complexity to the key. The performance of the proposed method is tested based on computing time and audio signal strength. The test results show that the message inserted in the audio file does not affect the file size, but rather affects the audio signal strength. Audio signals that experience additional data are at frequencies of 15 to 20 kHz and for other frequencies only experience additional noise.

Abstract - Partial discharge is a partial electrical discharge event in isolation that is not directly connected between the two conductors, which discharges can occur either near or not on the conductor. An Archimedean spiral antenna is designed to detect partial discharges in high voltage equipment. Electromagnetic waves generated by partial discharge will be detected by the antenna which has a frequency range of 300 MHz - 3 GHz. The next measurement of partial discharge uses an RC detector. The purpose of this study was to determine the performance of Archimedean spiral antennas which were then compared to RC detectors. Based on the results of tests carried out as many as 50 times, both the spiral arsenic antenna or the RC detector showed good results. Antennas get slightly lower yields, due to the reduction in the flow of electromagnetic waves on the metal walls of high voltage equipment. Whereas RC detector is better by displaying more sensitive results.

Abstract - Hospitals are an important part of the health system. This agency consists of several services. One type of main service that is quite complex and needs to be considered is inpatient installation. The hospital should make a structural and functional utilization effort by increasing the utilization of service space related to the number of available beds. To measure utilization of facilities in inpatient services, an indicator of inpatient services is needed to measure it. These indicators include BOR (Bed Ocupanccy Rate), which is the percentage of beds filled, LOS (Length of Stay), namely the average length of stay, TOI (Turn Over Interval), which is the average free time of bed, BTO (Bed Turn Over), namely bed productivity. From the values produced, later it can be used as material for determining service facility policies in the future. The purpose of this study is to create a model with a system dynamic so that it has an ideal indicator value. The scenario in this research is to increase utilization of bed use, the first strategy of this scenario is to increase the number of patient visits, because based on reference data the patient's visit is too low. This is evidenced by the value of the BOR which is less than the ideal value. The second effort is to maximize patient care. The results of the scenario show that in 2019 to 2030 the average score of BOR was 79%, LOS 3 Days, TOI 1 Day, and BTO 41 Times.

Abstract - The quality of the components of the machining process is determined by the value of surface roughness and dimensional precision. This study uses the Central Composite Design experimental method on the Response Surface Method. To determine the variation of experiments, three factors and three levels were used, the specimens used were mild steel with a total of 20 experimental variations in the EDM (Electrical Discharge Machining) machining process. Then the surface roughness and dimensional precision are tested. Optimization is done by the method of non-linear programming, where the first response is surface roughness and the second response is the precision of the dimensions of the length of the machining process. The results of the analysis show that the strong current influences the surface roughness and dimensional precision. While on time and off time do not really affect the surface roughness or precision dimensions. Optimization with non-linear programming techniques produces a minimum surface roughness of 3.805880 (µm) and dimensional precision of the maximum machining time is 175.2290 (minutes) with a current adjustment of 3 (Amperes), on-time 100 (µs), and off-time 20 (µs).

Abstract. Madurese language is one of the regional languages in Indonesia. This laguage used by the Madurese people. Preservation of Madurese language now is minimal. Many migrants come from outside Madura, so communication between the surrounding communities in the Madura region often uses the national language, Indonesian. The use of Madurese as a language of communication began to decrease. This research is an effort to preserve Madurese language by utilizing the translator system technology. Madurese language is a regional language that is difficult to learn, because there are many differences found between writing and pronunciation. To overcome this problem this reasearch develop text to speech module in the Indonesian-Madurase language translation system. There are 3 versions of Madurese language level: Enja’-iyyeh, engghi- enten, and enggi-bunten. The conversion of text into sound is used with the help of syllable recording data created by the author. The process of chopping words into syllables is done using the two-level Finite State Automata (FSA) method. The output of the first level FSA becomes input for the second level. The application of FSA in Text to Speech applications is effectively used with accuracy value of 90%. The resulting sound output is in accordance with the results of syllables, but the pronunciation of some translated sentences does not have the correct intonation. The accuracy results of the intonation pattern in pronunciation of the system is 85%.

Abstract. In order to develop the steering control for collision avoidance behaviour, robot must be able to determine its heading orientation with respect to environment. Orientation can be measured by dedicated sensors or through visual features perception. In vision-based orientation estimation problem, most of approaches are making use of a matching process between pair of frames. This paper proposes a method of estimating robot's heading orientation by using only a single-frame of fish-eye image. CIE-LAB colour space is applied to handle colour and illumination intensity change. Straight line segments are extracted from thresholded CIE-LAB image take advantage of Progressive Probabilistic Hough Transform. Angle of the corresponding line segment is measured using combination of Law of Cosines and quadrant principle. Heading orientation in yaw angle is estimated by implementing voting mechanism based on region grouping and length of perpendicular line. Some experiments are made in robot soccer field environment to compare orientation estimation system against IMU's measurement. Discussion about the performance and limitation of the system are included in this paper

Abstract - At present, the adsorbents generally use bentonite and activated carbon, but the availability of bentonite is less so that other alternatives are needed for substitution of bentonite as an adsorbent. One of the materials that have the potential as an adsorbent is the ceramic industry waste (ceramic clay). Ceramics clay containing feldspar which before being activated using sulfuric acid has a ratio of concentration between silica and alumina (silica/alumina) of 3.6, so a process is needed to increase the ratio of silica and alumina. One such process is by activating ceramic clay using sulfuric acid. The characterization and adsorption performance of adsorbent from ceramic clay were studied with various acid concentration. Ceramic clay powder was activated with sulfuric acid. The adsorbent particles were characterized by IR Spectra, X-Ray Diffraction, X-Ray Fluorescence, and BET. Various concentrations of sulfuric acid solutions for activation have a significant effect on the characteristics and performance adsorbent. This is indicated by XRD analysis where the characteristics of the adsorbent have feldspar (Ca-KAl2SiO3) content with the ratio between silica and alumina increasing around 4.3-4.8 with an increase in sulfuric acid concentration from 10-30% and adsorbents in the form of mesoporous crystalline structure. The characteristics of adsorbent with IR Spectra analysis showed that the presence of silicate alumina groups, so the products have the potential as a bleaching agent. The best surface area is produced at a concentration of 15 % sulfuric acid solution with one hour activation time which is equal to 117.44 m2/g.

Abstract - A company needs to improve its performance, especially in terms of quality, in an effort to assure its survival in the business competition with other companies. Therefore, the company needs to measure its performance so that it can find out its current position in the competition and how to improve said position and achieve its goals. Nowadays, many companies try to improve themselves by putting more emphasis on product quality, which is an external kind of quality, instead of on the internal quality of the company. This strategy will not yield the best result in the long run because the internal quality affect the quality of the resulting products. One of management systems that put emphasis on the internal quality and consumer satisfaction is Total Quality Management, which involves all members of the organization. One approach to the aspects included in Total Quality Management is to use the Deming Prize, which reviews the internal quality based on several categories. Based on the results and data analysis, it can be seen that the score for organizational variables is 3.41; standardization of 3.00; control of 2.81; analysis of 2.59; and influence of 3.30. However, there are several categories in the variable that are lower than the terget score, among others, job analysis, organizational goals, work tools, measurement, employee input, and rewards.

Abstract - Calcium phosphate compounds are one of the biomaterials that are widely used for bone reconstruction because they are biocompatible and have a chemical composition that is close to the inorganic components present in the bone. Two types of calcium phosphate that are widely applied to the bone reconstruction process are hydroxyapatite (Ca10 (PO4) 6 (OH) 2) and β- Tricalcium Phosphate (Ca3 (PO4) 2). This research develops the manufacture of β-Tricalcium Phosphate by reacting calcium compounds derived from chicken eggshells and phosphate sources derived from dinatrium phosphate (Na2HPO4) using precipitation method which is carried out with variations in sintering temperature 600 to 1000 °C and sintering time of 1 to 5 h. The results of X-Ray fluorescence (XRF) analysis showed that the Ca / P ratio obtained was 1.74, at the sintering temperature of 1000 °C and the sintering time for 5 h. These results have approached a standard where the ratio of Ca / P on Tricalcium Phosphate is 1.5. While based on the results of X-Ray Diffraction (XRD) analysis that in the sample formed two types of Calcium Phosphate namely β-Tricalcium Phosphate and Hydroxyapatite so that it can be said that the product produced is Biphase Calcium Phosphate. The high percentage of β-Tricalcium Phosphate is 81.9% with the 3 highest peaks, namely at the angle 2θ of 27.83 ; 31.03 ; 34.42 is obtained at the sintering temperature of 1000 °C and at the sintering time is 5 h.

Abstract - In foreign language teaching and learning process, comparing the two languages between the source language and target language being learnt can not be avoided. According to Carl James, (1980:3) [2], Contrastive Analysis is a linguistic enterprise aimed at producing inverted two-valued typologies, and founded on the assumption that languages can be compared. Meanwhile (Baker, 1998:48) [1] said that contrastive analysis might also provide some explanations of difficulties encountered by a translator in translation. In line with these two statements, it could be assumed that contrastive analysis is closely related to translation study due to the fact that in translation activity, a translator has to compare the two languages, source language and target language. This study aims at describing the relationship between contrastive analysis and translation study. Based on the study analysis, contrastive analysis could be classified into 2 (two) main categories, they are micro linguistic contrastive and macro linguistic contrastive. The first contrastive referred to the language study which is analyzed in accordance with the rule and structure of the language itself. Meanwhile the second one is concerned with the relationship between the language and some other related factors, such as in analyzing the text or discourse. A study on contrastive analysis is also required in language teaching, evaluation and research and translation as well. Furthermore, the relationship between contrastive analysis and translation study was bidirectional. On the other hand, the translation of specific pieces of text might provide the data for contrastive analysis. Therefore, a translator would not find if difficult to do translating a text if the source text being translated had similarities of its linguistic aspects with those of the target one.

Abstract - The presidential election campaign in Indonesia which was held in 2019 attracted the interest of the Indonesian people. People expressing their emotion through social media, one of which is Twitter. Supervised learning is used to classify user’s emotion of that issues. The goal of this research is extracting the emotional content in tweets. The interest is in whether the text is an expression of Twitter users' about the presidential candidates and whether this online forum represents the election results. For this purpose, text mining techniques are performed and we will compare Naive Bayes Classifier and SVM in classification process. The result showed that Naive Bayes Classifier and SVM have good performance for classifiying text and each of classifier have not outperform the others. The result also showed that stemming step in text pre- processing do not give any significant result in model accuracy, because twitter data use informal languange like abbreviation or slang.

Abstract - Student grouping, particularly in high school, is a necessary process to divide and classify students into classes based on their abilities and interests. Each school may have different approaches to decide the grouping, but most schools use academic grades. The activity occurs every new academic year and schools with plenty of new students registered may feel a bit overwhelmed with this grouping assignment. A decision support system which can automatically perform grouping on a list of students may be able to help the school’s staffs with this repetitive task. A self-organizing map (SOM) is an example of unsupervised learning algorithm using an artificial neural network structure to produce a low dimensional representation from a given input. However, SOM is also known as one of clustering techniques, since dimensionality reduction may also be seen as reducing (or clustering) input data to lower dimensions (or clusters). This research aims to group new enrolled students to a high school based on their academic grades using a SOM learning algorithm. The grades came from their rapport books and national examination results from their previous study. The resulting groups are three distinct clusters which represents Life Sciences, Social Sciences, and Linguistics study areas.

Abstract - Now the use of information technology has changed citizen’s styles and lifestyle. Public services that are practical, very fast and automated is the need for majority of Indonesian society. Coupled with various requests for public services needed by the community with a variety of specific case studies. This certainly has implications for the government in presenting services that suitable with the various needs of the citizen. On the other hand, in increasing the effectiveness and efficiency of public services, the government has shifted its business processes by increasing the adoption of e-government. However, the fact is the IT investments that can reach tens or hundreds millions rupiah every year can be said to be almost non-existent by governments where most of the operational processes are carried out electronically. To overcome this problem, the government should not simply shift the business process with IT adoption on a large scale. The government needs to adopt a model of organizational agility to support government IT agility. In anticipating this, several previous studies have contributed to developing an organizational agility model with IT support. However, the model developed is still not enough to achieve organizational agility. Therefore, in this study will synthesize some previous theories relating to organizational agility using IT support. The result of this study are an analysis of the synthesis of the agility process models of government organizations with IT support.

Abstract - Nowadays, progressive parking systems still have disadvantages. It only serves to notify total parking rates to motorized vehicle users when they are still in the parking area. Besides, the payment uses cash. Meanwhile, some users want to pay parking fees using tokens or virtual money. It has dual functions. They are a total parking tariff notification online and to reduce the leakage of parking rates because parking users are not given tickets by park officials. Moreover, it can find out the position of the vehicle in the parking area. By using the GPS Module, it will send data to Arduino Uno if the vehicle is in the parking area. Furthermore, it will activate the initial parking time with the Wemos D1 Mini controller. Later, it will provide notifications on the user's smartphone using the Blynk application. Users can find out the total parking rates that will be paid through notifications on the smartphone and directly cut the balance in the parking user account progressively. The trial of an opened area progressive parking system based on the Internet of Things (IoT) produces a tool that is able to provide modern notifications using wireless or hotspot connections.

Abstract - The most important point in network services is security of access in the port . However, the problem that occurs is an open port or access that cannot be accessed with authentication that can facilitate unauthorized users to be accessed by the server. This is the basis for increasing access rights to the server that is built without having to close the port used by the user. Therefore a port knocking method is needed. Port knocking is a security system that can perform a function that is blocking unwanted access. In principle, port knocking successfully closes all ports on the server. If the user needs access to the server, the user does a "knock" to use the service, then if the user has finished accessing the port is closed again. The system built in this study uses three ports, namely port 22 (SSH), port 23 (Telnet), and port 80 (Web). Port Access time is 10 seconds each. Based on the results of the analysis and testing of the system implementation carried out, the results of the system can be run properly and can improve the security of network systems that are built compared to networks that do not use Port Knocking security. In research assessing on public and local networks. According to the results analysis, carrying out a remote server via local time requires faster time from a remote server through the public. In the SSH protocol there is a difference in time of 2.42 seconds, Telnet 2.14 seconds, and Web 2.19 seconds.

Abstract - In any game where the player must face large formations of enemies, the way the formations are formed significantly influences the difficulty level of the game. As proper difficulty levels are essential to player’s enjoyment, the enemy formations need to be arranged properly. In this paper we experimented with how to procedurally generate enemy formations in a vertical scrolling shooter game while keeping the difficulty levels proper. Generations of the formations were done with genetic algorithm where the fitness function calculated two variables: difficulty curve, which reflects a formation’s difficulty level, and enemy variety. The difficulty curve took into account difficulty points, which measured the danger levels of on-screen enemies throughout the game’s duration. The fitness of difficulty curve of an enemy formation was acquired through point-by-point comparison between the curve and a human-designed one, which represented the ideal difficulty curve as intended by the game’s developer, and calculation of the root-mean-square error. The genotype of an individual was represented by a 5x40 grid containing enemy genes and empty space genes. We ran 300 generations in total and each was done in 100 iterations and had 40 individual genotypes. The results show that the amount of enemy genes in initial genotypes influences the population’s fitness progression. We then discuss the implications of our findings and possible directions of future researches.

Abstract - Face recognition system is still a topic that is widely studied today, because it has problems that are quite complex. One problem is related to the illumination factor, which significantly influences face recognition performance. One of the methods often used for object recognition problems that is influenced by illumination factors is the obust Regression, which is also used in this research. The problem to be solved is related to the performance of face recognition in various lighting conditions. Using one of the face databases, the Yale Face Database B Cropped, an experiment was performed on each lighting condition of the face data. In the Yale Face Database B Cropped, there are 10 individuals, where each individual has 64 variations of images based on illuminations which are grouped into 5 subsets according to their contrast level. Experiments are generally carried out using all subsets as training data and all other data as testing data, where the results show general face recognition performance (in all lighting conditions). In this research, experiments were carried out for each subset as testing data, where the results showed the performance of face recognition in each lighting condition. The experimental results showed the highest face recognition performance in subset 1 (98.21%), while the lowest performance is in subset 4 (84.46%). The trend of the experimental results shows that the face recognition performance of the Robust Regression method is getting better on face data with a higher level of contrast.

Abstract - Global and local thresholding are two thresholding approaches for white blood cell (WBC) image segmentation. Global thresholding determines the threshold value based on the histogram of the overall pixel intensity distribution of the image. In contrast, adaptive thresholding computes the threshold value for each fractional region of the image, so that each fractional region has a different threshold value. In this work, we are assessing both of these approaches for two threshold values. We extended the Otsu’s equation to calculate more than one threshold as it originally designed to find only a single threshold value. Adaptive thresholding first divides an image into fractional-image by considering an imaginary bounding box that surrounds the location of WBC, which involves the Gram-Schmidt orthogonalization method. For segmentation performance evaluation, we compare 35 blood smear test images which segmented by our proposed method, with their corresponding ground truth image to representing them in Zijdenbos Similarity Index (ZSI), precision, and recall measurement. Experimental results show that adaptive thresholding achieves average ZSI, precision and recall, 92.5%, 91.79%, 94.03%, while global thresholding achieves 30.72%, 23.38%, and 99.39% respectively.

Abstract - The smart city is being developed in many big cities to support local governments for resources and infrastructure optimization in terms of enhancing services for the citizen. Large investment costs are required to implement a communication network for the smart city infrastructure (i.e. Internet of Things (IoT) devices) using 4G or Wi-Fi networks. This study aims to implement Delay Tolerant Network (DTN) as a low-cost alternative network for the smart city. We use Surabaya smart city plan scenario in which smart mobility services are provided in city transportation and infrastructure. The IoT devices are installed in numerous locations and continuously transmit messages to the monitoring server located in the city hall, bus and car employed as a DTN node. In this paper, as a preliminary research, we investigate the performance of well-known DTN routing protocols (Epidemic, Maxprop, and ProphetV2) with our proposed protocol called Spray and Hop Distance (SNHD). The evaluation is performed using the ONE simulator in terms of the number of delivered messages, the average latency, and the overhead ratio. The results show the performance of SNHD is better than the well-known DTN protocols in various conditions when the total size of delivered messages is large. Unfortunately, none of those routing protocols has a good performance in all of the scenario conditions. In the future, we desire to implement this system in real smart city system in Surabaya and do simulation with more realistic scenario such as real traffic-trace.

Abstract - Manual workers are still commonly found in various work activities. Manual work done repeatedly with monotonous movements and long working time has the potential to cause work fatigue. In repetitive monotonous motion it can overload the muscles. Incorrect work posture can lead to excessive fatigue. This poor work posture is often caused by the design of work facilities that are less concerned with conformity with its users. From this study it was found that the current working method is less ergonomic because the testing with RULA and OWAS the majority of the indicators are on a scale of 4 and must be changed how its works. On milkfish management workers, refining milkfish spines, burning milkfish is a monotonous repetitive work that is not supported by appropriate facilities. Work posture with a stand and a twist and often bending. This study aims to redesign the work station to get a good work posture. designing work stations using 8.2 software jack. Work stations consisting of tables and chairs are designed with due regard to anthropometry and operator motion requirements. Design evaluation is done by evaluating the work posture using biomechanical analysis, using a toolkit analysis that includes analysis of SSP, LBA, RULA, and OWAS. Evaluation results in workers sitting with a well-built body position, the direction of the head parallel to the direction of the object subject to work, and the worker being avoided from the bending position and twist

Abstract - The main road that connects the city of Sidoarjo to Surabaya is the intersection of Gedangan. By 2018 it has reached saturation by having a poor service level. More severe conditions will occur in the next 10-20 years. One of the government's efforts to overcome the problem of congestion, damage structure is the construction of flyover or other alternatives by widening the road. The purpose of this study is to determine the characteristics of the traffic and to save vehicle operating costs before and after the construction of a flyover at the Gedangan intersection. The method for predicting Vehicle Operating Costs (BOK) is to use PCI method. This study predicts Vehicle Operating Costs (BOK) to determine cost savings. The scenario for predicting BOK is that 80% of the vehicle volume will pass the Fly Over, and 20% still use the existing road. The results showed that the cost savings of Vehicle Operational Costs (BOK) of existing roads compared to the use of flyover in 2019 was IDR 15 Billion. In 2039 the savings are IDR 77 Billion. Another discussion is that if the road is only widened without flyover, then the BOK cost savings in 2019 will be IDR 4 Billion and in 2039 it will be IDR 27 Billion.

Abstract - Traditional tropical architecture is built using local materials by applying passive design strategies to fix heat problems so the occupants feel comfortable and protected. Over the years, climate change causes rising temperatures and modernization causes the aesthetic element to become important in urban areas. Modern Tropical is a design trend that is now developing after the era of modern minimalist trends which not only tried to solve the heat problem but also the aesthetic problems of tropical architecture. This research aims to evaluate thermal performance in the modern tropical-style house in response to climate change and also how they adapt and modify traditional tropical architectural elements to improve their thermal performance by using the simulation method with the assistance of ECOTECT software. The results showed that houses that adapted and modified elements of traditional modern tropical homes up to 95%, showed better thermal performance. That house can provide thermal comfort for 7 hours and only 31% of percent dissatisfaction. Elements of roofs, openings, sun shading, and local material coatings on traditional architecture are elements that can be adapted and modified in modern architecture. So, tropical architecture no longer looks old fashioned but more stylish while responding to environmental issues.

Abstract - . Tumpeng is one of the ceremonial facilities used almost in every Hindu religious ceremony. Many people take advantage of these opportunities as a home-based business. At present the craftsmen encounter obstacles in the process of drying the cone. Currently the drying process still uses the manual method, namely by drying it by utilizing direct sunlight. In the previous research, the product planning for cone drying machine has been carried out, where the results obtained from this study are an increase in the productivity of the drying machine from the drying machine which was previously used by the cone maker of 683.33%. From the results of studies conducted by the hot air entering the drying chamber from the results of the previous engine design, it is likely that conditions on level 1 shelves and level 2 shelves have temperatures that are quite high compared to other rack levels because this air is circulated at level 3, 4.5 and 6. To get the air distribution between the level of the rack evenly, it is necessary to do a redesign of the tool. The alternative that can be done is by circulating hot air from rack 1 to rack 6, another alternative is to try variations in air distribution in the drying chamber by varying the cone seat holes.The redesign method that was carried out was to replace the existing distribution before the air out of the level 3 blower in the rack was changed to the air out of the level 1 rack entry blower, and the cone seat was made varied by random holes, concentric holes and zigzag holes.From the results of engine redesign after testing the air distribution in the drying chamber with a random hole stacking model, the highest temperature is found in almost all shelf levels, except at the level 1 rack the highest temperature is achieved by a concentric perforated pedestal model that reaches 183 oC. Judging from the hot air distribution, the randomly hollowed cone seat model provides a more even distribution of hot air compared to the concentric and zigzag hollow cone seat model.

Abstract - Tracking application is widely used to help outdoor activities. One of them is used to help tourists who do tourist destinations in group activities. Tourist tracking application requires data on the position of tourists on earth. This coordinate data can be obtained using latitude and longitude data from GPS (Global Positioning System). Coordinate latitude and longitude position of tourists from time to time are stored in a database. Database Selection for media storage will determines the level of speed and ease in accessing data. There are some differences in designing the structure of the MySql and Firebase databases. Relational Database begins with identification of entities involved in the system. One entity with another entity is related and has a cardinality level of the relationship. Relational database implementation in the form of tables in normal forms that are interconnected. Data will be stored in columns and rows. Normalization of tables causes high query computation when calling data that involves many tables. Firebase, which is one of the NoSql databases, in building data structures is stored in JSON objects. JSON tree structures usually consider the display of information that will be presented to users. So that the generated JSON tree has high efficiency and speed in processing data. In this study a comparison between the design of the relational database structure, namely MySql and NoSql Firebase database structure was developed. Firebase is more power full for the development of applications which update data in realtime and and handle a lot of coordinate data such as tourist tracking applications. Applications that do not have complex data relations such as tourist tracking applications are more suitable to use firebase than using MySQL.

Abstract - This paper presents field analyses on the influences of condenser and evaporator approach temperatures of water cooled air conditioning system for a shopping mall. The mall building comprises food and non-food retail stores and uses a centralized air conditioning (AC) system to condition the entire building. The AC system comprises three chillers with the same cooling capacity. Chillers’ performance parameters included power consumption, condensing and evaporating temperatures, evaporator-condenser approach temperatures, pressure drop and cooling capacity parameters were hourly recorded for a period of one year. Performance characteristics of each chiller were evaluated at different condenser and evaporator approach temperatures and regression analyses were also established to examine the correlations and influences of the approach temperatures on the chillers’ performance. The analyses results showed that the increase of condenser approach temperature could increase the power consumption and reduce the coefficient of performance (COP) of the chillers. While evaporator approach temperature was found to have insignificant effect to the chiller performance. The results also showed that for the investigated chillers with condenser and evaporator approach temperatures maintained below 2 K, the approach temperatures had negligible correlation to the power consumption and the overall performance of the chillers. At this operational conditions, the water cooled air conditioning systems could operate at their best possible performance.

Abstract - Mathematics teaching is a learning process gives an understanding of mathematical concepts for students. The basic concepts of mathematics must be embedded well in each student so that understanding concepts at an advanced level can be easily mastered. Mathematics teachers play an important role regarding the problems faced by students when learning mathematics in class. A math teacher in addition to having the ability to master mathematical concepts well, is also required the ability to manage the class so that students can understand the concept well and learning achievement is in the high category. Mathematics is a subject consisting of great ideas that are connected to each other so that understanding cannot be separated because each concept will contribute to the other concepts. Most students still say that mathematics is a difficult and uninteresting lesson, therefore, a teacher needs to apply specific strategies used in the mathematics learning process so that it can change students' perceptions of mathematics into an interesting and easy lesson. The use of technology can help teachers and students learn mathematics, for example the use of GeoGebra software. GeoGebra software has the benefit of being able to make geometric paintings that are fast and precise compared to using paper and pencil and the existence of animation facilities provides a clear visual experience for students and teachers. One of the geometry concepts is to construct a flat triangle, in this study the discussion is to determine the special lines on the triangle using GeoGebra software and then determine the intersection of the special lines of the triangle.

[email protected]

Abstract - In digital images processing, there are three types of edges based on intensity changes. Namely, step edges, ramp edges and edges noise. An edge is defined as a set of pixels where there is an abrupt change in colour intensity over distance. On-ramp edges where gray levels change slowly, the Gradient Method is able to detect better. On step edges where the intensity or gray levels changes very quickly the Laplace method is able to detect better than the Gradient Method. In this study, three images were used as samples and identified the type of edge of each image. Furthermore, edge detection is performed with the first derivative operator Canny and the second derivative operator Laplacian of Gaussian. The results indicate that for step edges LoG provides better results, whereas for ramp edges Canny detects better. However, by selecting the right threshold that matches the σ (standard deviation), Canny is also capable to provide good edge detection results. The greater the σ value, the threshold was chosen must be small so that the results obtained are good and easily interpreted. The Canny operator produces a thinner edge and a firmer boundary between objects and between objects on the given sigma = 1 value while the LoG operator corrects better, especially on the steep part of the value σ = 2 compared to the value σ = 1.

Abstract - Bananas besides being a superior fruit plant in Indonesia, banana plants can be utilized as animal feedstocks, The results showed that the administration of banana stems as animal feed did not have a negative effect on the appearance of young sheep, and even showed more nitrogen in comparison with sheep receiving control rations. Banana skin can be used as a substitute feed for livestock, especially in broilers. Banana skin has been used as poultry feed, a mixture of banana peel and coconut pulp with a ratio of 2: 1 can be used up to 15% substitute for corn in broiler feed. Banana skin fermented with probiotics can increase crude protein content by 14.88% and rough seats by 11.43% which is good for broiler growth. Drought that occurs every year is the main limitation of the growth of banana plants. Drought in plants can result in slow leaf area increase and influence on the rate of photosynthesis so that it can reduce productivity and growth of plants. PEG 6000 was used as an effort in early detection of genotypes from plant varieties that tolerated drought stress. So far there has never been a study of plantain feathers against drought stress using PEG 6000. So this research is interesting to do. This research was conducted to obtain candidates for plantain plantain which are tolerant to drought as animal feed

Abstract - Production of chicken eggs will decrease below 30%, with a maintenance time of more than 1.5 years, but the old chicken eggs can still be consumed. The decline in chicken egg production does not necessarily reduce the quality of eggs chemically, but physically that these chicken eggs have advantages and disadvantages. The advantage is that it has a large size and weakness is that some shells are not normal. Therefore studies related to egg quality chemically need to be done to determine whether there is a decrease in egg quality in old chickens. Egg quality is generally influenced by feed and drinking water, some herbal plants given to chickens are thought to be able to improve the quality of chicken eggs. Some herbal plants that can be used include turmeric, ginger, cutchery, and red fruit extract. Red fruit has several good antioxidant compounds and fairly high xanthophyll. The purpose of this study was to determine and improve the quality of old chicken eggs. The method used in this study experimentally with 4 treatments and 10 replications. The variables observed were the quality of protein, fat, cholesterol, bacterial contamination and the content of omega-3 in eggs. The results showed that the average protein content was 10 -13%, 9-10% fat, cholesterol 331 - 338 mg / 100 g and Salmonella SP (negative). The conclusion of this study is that chemically the quality of old chicken eggs given herbs in the normal range and the administration of herbs do not improve egg quality physically.

Abstract - This study aimed to compare between Elandt-Johnson and Heligman- Pollard interpolation method in estimation of a complete life table for erderly. The range age started from 60 to 110 years. Rapidly increasing of elderly population both developed and developing countries has encouraged the government to provide programs for elderly to not assess the productive age. Life table provides data to estimate the elderly population. However, the data usually contains data aged 0 year. The neccessity to enable to find out the elderly data requires a life table. Yet, the problem occurs in some developing countries are that they do not provide a complete life table and only an abridged life table. Therefore, the study investigated a proper method to estimate the elderly life table by comparing the two interpolation methods such as Elandt-Johnson and Heligman-Pollard method. The results of the study found that the Elandt-Johnson method was more appropriate than the Heligman-Pollard method to estimate a complete life table of elderly by comparing the error value.

Abstract -- One of the most common inhibiting factors in the archipelago is the lack of availability of material resources and human resources. One of the options is the use of lightweight concrete precast using materials around the islands. The local material which is widely distributed in North Maluku is pumice but it has not been used maximally because so far it has only been used as pile material. This study aims to analyze the effect of partial substitution of pumice on fine aggregate in a concrete mixture. This research was carried out experimentally in a laboratory using UTM and divided into 2 stages. Stage 1, designing and analyzing concrete mix using pumice compared without using pumice, Phase 2 testing using concrete beam dimensions of 600x150x100 mm with an inter load of 150 mm. Beam test results show that the limited use of pumice in a concrete mixture does not greatly affect the strength of normal concrete beams, as indicated by the deflection value and strength of concrete blocks that are almost as large.

Abstract - Today, the smart city has become a trend in the world and in the city's governments in Indonesia. The typical geographic condition of the city, municipality and district government in Indonesia is more directed to the governance of island governments that have own factors, challenges and opportunities. One of the visions of the archipelago’s government is the Smart Islands vision, which is to make the islands become a smart city with connected islands, integrated, collaborations between stakeholders and improved public services with own local wisdom. However, the readiness level, the actual problems found in the existing conditions are not yet evaluated and measured. In this study, we conducted a smart city readiness assessment with the adoption of the Nusantara Smart Government Model (NS-GM), which was combined with the Model SPBE instrument on Presidential Regulation No. 95 on 2018 as the official regulation of the Indonesian government. We choose 2 case studies as an example of an archipelago’s government in Indonesia, namely Ternate City and district's government of Southern Halmahera because the area has the criteria as a government of an island region that has a vision of smart islands. Smart cities readiness assessment results show that 2 case studies that are measured in readiness, are generally still in the pilot stage with values in the 2 towards 3 phase model that we used

Abstract -- Acid Mine Drainage (AMD) is one of environmental concerns of mining activities and need to be prevented. One of AMD prevention method is passive method by blending PAF Material with Non-Acid Forming Material. One of constraint often faced by mining companies is the limitation of NAF material. Other Non-Acid Forming Material that is available and abundant near mine site is fly ash from Mine-Mouth Coal-Fired Power Plant Banjarsari. The Study of usage of fly ash as a blending material with PAF material in order to prevent AMD is deemed necessary. Different blending simulations of varying PAF material size (fine and coarse) and varying fly ash-PAF Material ratio (2:1; 1:1; and 0,5:1 by weight) are made and leachate water from kinetic test is physically and chemically tested. This study result shows that variation in OB-Claystone grain size is not influencing the acidity of leachate water. Blending FA with OB- CS with minimum ratio of 1,12:1 (by weight) is effective to prevent AMD generation. Acid-base equilibrium is met when ratio of mole-transfer between neutralizing mineral (periclase, lime and gypsum) to acid-generating mineral (pyrite) is 1:1 (by weight). The higher ratio of FA in blending, the lower oxidation and alkalinity-production rate. Rate of oxidation of pyrite and alkalinity- production rate is the same at OB-CS and FA blending ratio of 1:1,62 (by weight).

Abstract -- In designing of Remotely Operated Vehicle (ROV), the most important issue is how to formulate the movements of the vehicle. This paper proposes the mathematical model of ROV movement. Combination of statics disciplines and dynamics of ROV movement are needed to formulate the mathematical model of ROV. Statics refers to the forces and moments that work on the physical system around the equilibrium point, dynamics refers to the effect of force on the movement of the object. Linear mathematical models analyzed can be combined or separated by taking into account the circumstances surrounding environment such as velocity vector of the linear state of the vehicle body (surge, sway and up) and angular (roll, yaw and pitch). Simulation results show that the movement of vehicles, both basic and combined movements have reliable characteristics.

Abstract -- A lot of knowledge and techniques of image processing which are now available are widely various. Much research as well as development is conducted in terms of detecting ripe fruits, one of which is chili. It is one of the local commodities that is marketable. The process of being ripe chili is relatively fast. Generally, to measure ripeness is still carried out manually. The disadvantage of this method is that the level of accuracy is inconsistent, causing fruit decay in numbers. On behalf of lowering the risk of fruit decay, the research conducted uses index pixel method. This means itself is the normalization of variety illuminated by taking ratio in each group of smallest points in an image processing. In this study, the image taking of chili using box equipped with black background is confirmed to be useful in reducing time of segmentation process. When it is in the process of detecting image by searching for the average of index pixel, then RGB will be counted using Learning Vector Quantization (LVQ) that is the calculation utilizing weighing value. As a result, the classification of maturity level can be seen in the test with a very high percentage value and influence to detect fruit ripeness, signed by the color of RG pixels (red and green) by 94.9% correctly detected, the color pixel RB (red and blue) is quite influential by 93.9% correctly detected, and the color of the GB pixel (green and blue) which was less influential at 63.6% was correctly detected.

We offer HWOA with local search strategies. The solution in each HWOA iteration is improved using flip and swap mutations. Furthermore, HWOA is compared with several algorithms. We use numerical experiments to show the performance of the proposed algorithm. Comparative analysis with several algorithms has previously been carried out with ten variations of PFSSP problems. Based on numerical experiments, HWOA proved to be competitive compared to other algorithms.

Abstract - Recently, the problem of minimizing emission carbon in the industry has become a focus of much research. One of the efforts that were successfully carried out was managing the sustainable economics order quantity (SEOQ). However, several SEOQ had assumption such as (1) Transportation and warehouse costs are ignored, (2) Transportation emissions are avoided, and (3) warehouse Capacity Limit are ignored. In this paper, we developed the SEOQ model with warehouse costs and capacity limits. There are two proposed SEOQ models. Model 1 was the SEOQ model with Transportation and warehouse costs also emission carbon. At Model SEOQ 2, this model considered Transportation and warehouse costs, emission carbon, and capacity. We also proposed procedures to minimize total inventory costs. Finally, a numerical experiment was conducted to test the model. Based on numerical experiments, the proposed model useful to solve SEOQ problems with Transportation and warehouse also costs capacity limits.

Abstract - Advances in technology have increased the use and complexity of software. The complexity of the software can increase the possibility of defects. Defective software can cause high losses. Fixing defective software requires a high cost because it can spend up 50% of the project schedule. Most software developers don't document their work properly so that making it difficult to analyse software development history data. Software metrics which use in cross- project software defects prediction have many features. Software metrics usually consist of various measurement techniques, so there are possibilities for their features to be similar. It is possible that these features are similar or irrelevant so that they can cause a decrease in the performance of classifiers. In this study, several feature selection techniques were proposed to select the relevant features. The classification algorithm used is Naive Bayes. Based on the analysis using ANOVA, the SBS and SBFS models can significantly improve the performance of the Naïve Bayes model.

Abstract - The study of the behavior of embankments reinforced by geosynthetic construction on soft clay soil with and without a prefabricated vertical drain is described. The effect of a pre-loading with stage construction method to construct the embankment, the gain of bearing capacity, as well as the depth of compressible soil was also considered in this study. The limit equilibrium using Bishop and Fellenius methods was used in this study to determine the stability of the embankment. Vertical drain installation, combined with the stage construction method, substantially reduces the number of geotextile reinforcements needed. The number of geotextiles can be reduced by up to twice that compared with foundation soil without PVD. Furthermore, the combined use of geotextile and PVD can improve the performance of embankment height as well as increase the critical height of the embankment with geotextile reinforcements. Without PVD, the embankment will be safe against landslides (without geotextile) of less than 3.5 meters. When using PVD, the embankment critical height can increase by up to 7 meters. This condition occurs when the embankment is constructed using the stage construction method, geotextile reinforcement, as well as PVD installation for soil improvement.

Abstract - The global supply chain allows companies to distribute their product all around the globe. The companies have to prepare themselves with an integrated system that is involving the possibility to deliver the product to the farthest area within their regional target. However, the limited due date of products generates the distribution and inventory problem that is complex and challenging to solve. One of the methods to solve the distribution problem of products with the due date is to use the system thinking approach to identify the root of the problem. The Economic Order Quantity (EOQ) method is the most reliable method to discover the most cost-effective strategy, especially for products with the limited due date. The company for this case study is PT Y. The main problem of the company is stock out. The result shows the root of the problem in this company is the unstable demand from the customer, storage management, and distribution management. There are similarities between the three root problems. The due date and quantity are the factors that control the three root problems. The result also shows that the EOQ Model that is taking the due date into account is more expensive than regular EOQ model

Abstract - Malang city government created Bank Sampah Malang (BSM) that offers 3R concept (reduce, reuse, and recycle). BSM is the institution which is oriented toward reducing plastic waste, but their recycling process still has not considered the environmental aspect yet. In this paper, we developed a reverse logistics model for plastic bottle recycling in Bank Sampah Malang (BSM) with consideration minimizing the costs of reverse logistics and environmental impacts. The proposed model takes into account various parameters, including kinds of costs, availability of used plastic bottle, storage capacity, disassembling capacity, vehicle capacity, and demand of chopped plastic. Goal programming is used to formulate mathematical model and LINGO is applied to solve the model. Lingo results indicate the two goals have been achieved because the value of the positive deviation variable associated with the two goals are equal to zero. In addition, we got several decision variable solutions including: number of plastic bottles purchased from depot, number of bottle bodies moved to recycling area, number of bottle bodies recycled, and amount of chopped plastics delivered to firm

Abstract - Examination timetabling is included in the category of Nondeterministic Polynomial- Hard (NP-Hard) problems, namely problems that cannot be solved by conventional methods in finding optimal solutions. One solution to this problem is to use the Simple Random - Hill Climbing - Hyper Heuristic (SR-HC-HH) approach. But this approach still cannot produce an optimum solution. The researcher presents a critical analysis of the performance evaluation of the solution method used. The stages of this research include: (1) problem identification; (2) literature study; (3) data retrieval and understanding; (4) translation of mathematical models into data structures; (5) evaluation of the SR-HC-HH algorithm; (6) trial implementation; (7) algorithmic experiment parameters; and (8) analysis of results and conclusions. SR-HC-HH algorithm used in Hyper-Heuristics-based applications is able to solve timetabling problems in the Examination Timetabling Problem domain in the ITC-2007 dataset, but it is still not optimal. Parameters that can be changed in this study are the number of iterations (time limit) and algorithms for selection of Low Level Heuristics. Changing parameters in the trial scenario can also affect the results of a more optimum solution. The parameters to be explored in this study include LLH selection strategies and move acceptance in hyper-heuristics.

Abstract - Indonesian government has an organization that aims to manage basic necessity nationally, especially for rice commodity. The organization runs in the form of a business entity and has a program making welfare of the poor people by providing rice assistance. There is still over stock and out of stock in inventory while organization distributes this relief. That matter creates unbalance between commodity in inventory and commodity in distribution incurring a large cost. Prediction model using system dynamic in this study was needed to control the inventory and reduce over stock or out of stock. Causal loop diagram was used to describe the relationship between variables in the system and simulation was run with stock and flow diagram. Simulation was done by benchmarking the actual and the simulation results. The model that was built, tested using the Mean Absolute Percentage Error (MAPE). Based on the simulation results, the values of MAPE are below 5%. This indicates that the model can represent the real system and can use to predict variable for the future.

Abstract - Yellowfin tuna (Thunnus obesus) is one of the most important and most caught fish in the eastern Indian Ocean off west Sumatera and has extensive migration. To develop an appropriate prediction model and to understand the contribution of oceanographic parameters in the potential habitat of Yellowfin tuna, remotely sensed data and habitat modeling were used. Daily data of sea- surface temperature (SST), sea-surface salinity (SSS) and sea-surface height (SSH) were downloaded from the marine copernicus website, meanwhile fishing vessel position for Yellowfin tuna were obtained from fishing port Samudera, Bungus, west Sumatera, from January through December 2015. Daily fishing vessel position and environmental parameters were used for maximum entropy model construction. The model predictive performance was then evaluated using a threshold-independent metric, the area under the curve (AUC) metric of the receiver operating characteristic (ROC). Maximum entropy model results (AUC > 0.90) indicated its potential to figure out the spatial distribution of Yellowfin tuna. In general, SST (50.5%) is the most affective variable in the Yellowfin tuna distribution, followed by SSS (37%) and SSH (12.5%). This study showed that integration multi remotely sensed data and a modeling approach provide an innovative way to decide the potential fishing zones of the Yellowfin tuna in the eastern Indian Ocean off west Sumatera.

Abstract - The common problem occurs in fish mapping using autonomous surface vehicles (ASV) is pitching stability. Some researchers have indicated that problem affects the results of mapping. The target of this system is to design an Autonomous Pitching System (APS) for ASV using numerical simulation software. The simulation is done by implement APS into the system, producing an oscillatory motion from the ASV. For both dynamics of craft in short and long periods, APS with proportional controller (P), proportional-integral controller (PI), and proportional-integral-derivative controller (PID) are developed in order to minimize the oscillatory behaviour. It was found that for the short period dynamics, the APS with PI controller was the optimal controller, followed by the PID controller and then the P controller. For the long period dynamics, the APS with PID controller was optimal.

Abstract - Lung is one of the vital respiratory organs in the human body. Where during respiration, there is a process of gas exchange in the lungs by taking oxygen (O2) from the air and releasing carbon dioxide (CO2) into the air. Because in the process of respiration involves air in the surrounding environment, the more contamination of air is inhaled, can cause various lung diseases. If the lung diagnosis is done early, then lung disease can get health care earlier. Chronic Obstructive Pulmonary Disease (COPD) is a type of disease that blocks the flow of air into the lungs due to swelling and mucus or phlegm, so that the sufferer has difficulty breathing. In making this research, we want to make a design tool to detect COPD and determine its severity using medspiro (medical spirometer). COPD can be diagnosed by measuring the value of Forced Expiratory Volume in One Second (FEV1), Forced Vital Capacity (FVC) and comparing it with predictive values of FVC and FEV1. The results obtained from the manufacture of spirometers have FVC measurement errors of 5.8950%, and FEV1 measurement errors of 10.5030%.

Abstract. The abundance of cassava cultivation production in Indonesia needs to be balanced with the use of cassava itself to be a source of alternative food as rice subtitute. In this research was done the drying of tubers grater which was cassava to be dried into flour. This drying used a mechanical dryer which was a pneumatic (flash) dryer by using the heat recirculation method (the heat produced from drying was reused). The drying in this research was carried out with a variation of 2 air openings, which were openings for air speed (blower) and openings in the heat recirculation pipe. For openings in the blower, this research used 2 variations of openings, which were openings 50% (air speed 0.0603 m/s) and openings 75% (air speed 0.0768 m/s). For openings in the recirculation pipe, 4 variations of openings were used, which were openings 0% (without recirculated the heat), openings 25% (the heat returned was only 25%), 50% and 75%. The drying time was based on how long the material was in the duct drying. The results showed that, by doing heat recirculation, the value of heating and drying efficiency would increase. The drying in air recirculation 25% could increase the value of drying efficiency for about 5-6%, while in air recirculation 50% could increase the efficiency value for about 3-4%. The value of the heating efficiency of this research ranged from 57-86%. The drying rate constant of the cassava grater moisture content ranged between 0.16 to 0.194%/second.

Abstract: Food insecurity can be seen in terms of production, consumption, and distribution. The aspect of food insecurity is the ability to produce unbalanced with the fulfillment of needs. Production capability is not seen from the availability side, because availability can be met from the inter-regional supply. The consumption aspect is the inability to buy food because there is no purchasing power or the poor. The availability of food that does not meet the needs of the community resulting in food insecurity. Then the way to handle food insecurity in the region of Bondowoso is by distributing food that requires the shortest path to overcome the many areas that must be given assistance. Determination of the shortest path is a problem to find a path between two nodes with a minimum number of weights. The shortest path can be applied in the form of web-based application programs.

Abstract. Individuals post-stroke suffer deficiency of motor function and need more effort to exercise using cycling therapy. Virtual reality augmented cycling (VRAC) that incorporate compensatory strategies such as manipulation of virtual environment (VE) may change motor behaviour and increase exercise intensity while also being engaging and motivating. In this research, we try to examine perception and vision aspects of individuals post-stroke that affect the user interface to a VE when driving a VRAC by manipulating VE features such as gain related with human perception, and width and difficulty of path related with human vision. To examine those aspects, we divided two groups, namely healthy sedentary control (n=3) as reference and individuals post-stroke (n=7). From the examination results, it was obtained that both groups had given a good enough response to manipulation of VE features although there were no significant differences to individuals post-stroke when driving VRAC in wide path conditions. Manipulation of VE features affect cycling behaviours for individuals post-stroke and assist to transfer visual information in real world to virtual world for development of post-stroke rehabilitation using VRAC system.

Abstract. Humans often encounter obstacles in doing their work. Especially if the work is related to an emergency situation that concerns the safety of human life, it needs quick and appropriate handling. Telerobotic technology that has a haptic function is one solution to these problems. In this study a system of 1 DOF haptic manipulator with slave master configuration was developed using bilateral haptic manipulator control. In bilateral control the position and information are transmitted in two directions between two manipulators. Position information is obtained using a potentiometer and force information is obtained by representing the force with the current using the WCS2702 sensor. There are three control methods used, namely bilateral symmetrical position control, bilateral reflection force control and force feedback bilateral control. The best method of control is the bilateral feedback force control. In the force feedback bilateral control system, the slave can move following the master movement with a ± 2⁰ position error. When the slave arm is held by a hard object, the master arm is also restrained with ± 11⁰ position error. Whereas when the slave arm is held by a soft object, the reflection of the object is felt by the master arm with ± 10⁰ position error. Movement of the master and slave arms is lighter than using bilateral control of symmetrical position.

Abstract- The wound healing process consists of three phases, namely the inflammatory phase, proliferation, and maturation. An increase in the number of neutrophil cells and macrophages signifies an inflammatory phase. Fibroblasts and epithelialization indicate a proliferation phase, whereas in the maturation phase is marked by the occurrence of wound healing. Ginger (Zingiber officinale Roscoe) contains active substances, namely triterpenoids, flavonoids and saponins. Flavonoids function as anti-inflammatory. Although it has many benefits, the effect of giving ginger extract to neutrophil cells, fibroblasts, and epithelial thickness in incision wounds has not been studied. The purpose of this study was to determine the effect of ginger extract on the number of neutrophil, fibroblast cells, and epithelialization in incision wounds. The research design used was post test only control group design. Rats were divided into control groups given 1% CMC solvents and the treatment group were given oral ginger extract at a dose of 1 g / kg BW. The tissue was observed on days 1, 5 and 10. Based on the results of the Kruskall Wallis test, the p value was 0,000 with α 0,05, so it can be concluded that the administration of ginger (Zingiber officinale Roscoe) can reduce the number of neutrophil cells, increase the number of fibroblast cells, and increase epithelialization of incisional wounds in white mice (Rattus norvegicus).
