Despite the fact that, Craftsmen forms the greater part of the workforce in the construction site, of every deploying nation, because most of the construction works are done mannerly, yet Nigeria as one of the affected countries have not paid much attention on most of the basic challenges confronting craftsmen in their skill pursuit. The decline in interest of most youths today on construction activates has affected regular supply of the needed craftsmen in the construction sector in Nigeria especially in south east region. This paper is focused on reviewing the current challenges confronting the construction craftsmen in their career pursuit in Nigeria in terms of their welfare, career challenges and incentive, and make suggestions on how best to handle the affairs of these craftsmen to increase construction productivity and construction sustainability. In the past most, so many scholars have dwelled on shortage of craftsmen without particular reference to the problems of the craftsmen career challenges during their skill acquisition pursuit. Therefore the study will add to the body of knowledge by addressing the challenges confronting the craftsmen during their career pursuit in the construction industry in Nigeria.

This study aims to model and validate PM10 concentration from transport sector and its relationship to the characteristics of traffic, wind speed and wind direction. PM10 was analysed using the gravimetric method. Sampling were held twice, with the first sampling were carried out at 3 monitoring points representing different angles of arrival of the wind direction towards the road (α), ie 0o, 30o and 60o. For validation, a second sampling were carried out at 0o, 45o and 90o angles. Statistical analysis uses correlation and regression tests. Validation tests were carried out using the Pearson Product Moment formula and the Two Variance Test. The sampling results showed that the highest concentration was on a road with an angle of 60o, with a concentration of 107.748 μg/Nm3 (number of vehicles 3,219 units and wind speed 0.3 m/s) and the lowest concentration at an angle of 0o with a concentration of 19,298 μg/Nm3 (number of vehicles 680 units and wind speed of 0.98 m/s). Increased traffic volume and density are proportional to the increase in PM10 concentration. Whereas vehicle speed and wind speed have an inversely related relationship with increasing PM10 concentration. Decrease in PM10 concentration in traffic volume from α 90° to 60° by 26%, α 90° to 30° by 29% and α 90° to 0° by 61%. Decrease in PM10 concentration at traffic density from α 90° to 60° by 17%, α 90° to 30° by 33% and α 90° to 0° by 51%. The results of the Two Variance Test showed no

significant difference in yield variability between the two PM10 parameter concentrations. This is indicated by the value of the Test Ratio (RUf) lower than the Critical Point. Validation test using the Pearson Product Moment formula shows that the two equations tested can be declared valid and can be used to determine the concentration of PM10. This is indicated by the value of r (correlation coefficient) calculated greater than the value of r table in all parameters.

As many as 19 locations of Horizontal to Vertical Spectral Ratio (HVSR) measurements had been conducted in Darul Imarah District, Aceh Besar, Indonesia. This survey is important to analyze a structural characteristic through a shear wave velocity (Vs), considering the survey area is near to Aceh Segment Fault. One of the methods to obtain Vs is 1D HVSR inversion. The final objective of the research is to investigate the Vs structure in Banda Aceh and Aceh Besar passed by the Seulimeum Fault and the Aceh Segment of the Sumatran Fault. In this paper, we analyzed only four of 19 measurement points of HVSR data to estimate of Vs, there are in AB03, AB08, AB09 and AB19 points. The inversion results show that the four points have four layers with different shear wave velocity. The Vs30 of AB03, AB08, AB09 and AB19 are 150.90 m/s, 197.16 m/s, 150.45 m/s and 316.80 m/s, respectively. The AB09 has the lowest Vs30 (highest amplification) than the other points and has soft soil composition. Furthermore, based on the Vs30 and amplification, the subsurface of AB03, AB08 and AB19 may have combination soft soil and stiff soil in 30 m depth.The analysis of Vs values will be conducted at all sites and a 3D velocity structure will be derived from the interpolation of 1D velocity.

As an effort for water resources conservation, a fixed-bed column was applied to remove nitrate from groundwater using pumice as adsorbent. The column performances were evaluated by varying the influent concentration (50 mg/L dan 80 mg/L) and influent flow rate (2 - 3 gpm/ft2 equal to 43–65 mL/min) with 85 cm of adsorbent bed depth. The results indicated that the increase in influent concentration increased the amount of nitrate and cause the earlier breakthrough time. Furthermore, the increase in influent flow rate caused the column exhaustion time to occur earlier resulted in the shortened lifespan of the column. The column system with a bed depth of 85 cm and flow rate of 2 gpm/ft2 (43 mL/min) for 80 mg/L of influent

Cold formed steel (CFS) is mostly used for short span structure in Indonesia because its advantages in cost and time efficiency. However, there is still limited number of long-span construction using cold formed steel because its buckling issue. Throughout the time, there are many researches that revealed the buckling issues can be prevented; one of them is combining their section. Then, CFS structure should give full structural performance. This research aims to analyze the performance of long-span roof truss, 24 m, using CFS back to back channel section. Two types of roof trusses, model 1 and model 2, are compared to get better configuration for long-span roof truss. Analysis is conducted by 2D model and analytically calculated based on SNI 7971:2013. The results are the maximum axial tensile force and axial compressive force, and also deflection. They will be compared to CFS back to back channel section capacity. This analysis obtained the stress ratio and deflection of both configurations. Based on analysis results, CFS back to back channel section safely withstands resisting axial forces by giving compressive ratio number around 0,54-0,72. Then, model 2 has given better structural performance, stress ratio and deflection, than model 1.

Liquefaction Resistance of Sand Mixed with Fines-Grained for Reclaimed Land
Yelvi1*, Handi Sudardja2, Shany Elizabeth3
1,2,3 Civil Engineering Department, State Polytechnic of Jakarta
Liquefaction due to earthquakes can cause collapse, subsidences, landslides, lateral spreading, and sand boiling. The damage is commonly occurred at layer of water-saturayed granular sedimen with low relative density. Reclamation areas formed by loose sand are areas with high risk to liquefaction, such as damages occured in the reclamation area of Tokyo Bay Area (Fukushima Earthquake, 2011) and Wellington Port (New Zealand Earthquake, 2016). Some research have stated that the gradation of soil grains, relative density and maximum acceleration of an earthquake affected the soil's resistance to liquefaction. This paper presents the results of the experimental studies about the influence of fines-grained in the sand that has liquefaction potential which is used as a reclamation material to review its resistance to liquefaction. The experimental studies were carried out by adding fines-grained. A mixture of sand with fines-grains was made at a relative density of 25%, 50% and 75% under earthquake load with a maximum acceleration of 0.3 g. Based on the test results, the liquefaction resistance increases well as the increase of fines-grained and relative density.

This research was conducted to determine how the conditions change order and timeperformance on a construction project. The population in this study were employees of one project in Jakarta with a sample of 30 employees. Analysis of the data used in this research is descriptive analysis. The results obtained showed that the change order is included in the not good category with a percentage value of 49.79%. While the time performance included in the category is also not good with a percentage value of 42.67%. Based on the results of calculations in the regression analysis, the results show that change order has a positive effect on increasing the time of implementation of construction project work (time performance) and the most dominant change order indicator influencing time performance is the lack of information when planning a project. Based on the calculation of Pearson product moment correlation, change order gives a fairly strong relationship to time performance, that is equal to 0.556 while the calculation of the coefficient of determination, change order affects the time performance of 30.9% and the rest is influenced by other variables such as costs, lack of communication between owner and contractor, employee performance, etc.

Sadtim1, Dalrino1,*, Hartati1, Suhendrik Hanwar1, Aguskamar1
1Civil Engineering Department, Politeknik Negeri Padang
Numerical bed change study of Danau Diatas and Danau Dibawah was conducted. Hydrodynamic and sedimentation simulations are carried out using monthly discharge input limit conditions obtained from the calculation using the FJ Mock method. The RMA2 numerical model is used to obtain current patterns that are calibrated against the measurement results. Estimated land erosion is calculated using the USLE equation. Sediment discharge obtained from the USLE equation is used as an input of sediment sources to obtain sedimentation patterns using the SED2D module. The results of the modeling of the current pattern get the current velocity ranging from 0 - 0.05 m / s for Danau Diatas and between 0 - 0.04 m / s for Danau Dibawah. The bottom profile change due to the distribution of sedimentation was found to range between 0.12 ~ 0.21 m in one year simulation with a radius of 0,53 and 1,72 km. This study is a preliminary study to get an idea of the potential for sedimentation. The validity of the results is recommended to use bathymetry measurements to see the bed changes that occur with the time of measurement. The initial description obtained has shown the need for efforts to regulate land use and commensurate with lakes in anticipation of silting of lake waters due to erosion.

Unlike developed countries, traffic characteristics in developing countries are dominated by passenger cars and also motorcycles. For example is Indonesia where more than 70% of transport mode share is contributed by motorcycles and a number of the riders are below age indicating poor law enforcement. This figure is suspected to worsen the transport negative impacts like road accidents as well as congestion level due to poor behaviour of motorcycle riders. Therefore, any efforts to reduce the trip number by mode of motorcycles on the road as well as improving their rider behaviours are necessary. For example is by managing motorcycle parking facilities. The results of this study are expected could be a considerable contribution for policy makers in minimizing the negative impacts of transport, in particular related to motorcycle usage.

1Civil Engineering Department, Politeknik Negeri Padang
The riverbed around the abutment can experience scouring caused by flow, because its is always directly related to river flow. Abutment can obstruct the flow of rivers causing changes in flow characteristics which in turn will cause local scouring around these buildings. Toe Scour around abutment will be very dangerous and cause loss of stability on the bridge. The case of structure failure on Batang Kalu bridge in Korong Pasa Usang Nagari Kayu Tanam, Padang Pariaman Regency on Monday (10 December 2018) is a clear example of toe scouring. A case study of toe scour was on the Batang Kalu River bridge structure has been carried out. Rainfall data closest to the study location, Kandang Empat Station was used to minimize the errors in the calculation of flood discharge design. Numerical modeling with HEC RAS and scouring estimation with some empiric equation was conducted to predicting scour depth on abutment. Simulation results show scour depth results to an average of 2.731 m and close to the scour depth that occurred in the field (2.83 m). Results showed that the local scouring in the Batang Kalu River bridge structure can be suspected as the influence of the increasing river steepness. Discharge that is triggered by heavy rain with a long duration and increased river flow velocity due to steepness has the potential to create a very intense scouring. Increasing of steepness may have been caused by sand mining activities in the upper reaches. Further studies are needed to see the potential slope changes due to exploitation in the Batang Kalu River upper reaches

Many adults experience tooth loss due to accidents and lack of care. This causes various problems, one of which is a problem in chewing food. One solution that can be used is the use of dental implants. Dental implants that are currently made of titanium Ti-6Al-4V at a very expensive price. One of the newest types of titanium alloy material that can be used with relatively cheap prices is Ti-12Cr. As a new material, the effect of heat treatment processes on mechanical properties has not been investigated in more detail. So that research is needed on the effect of heat treatment with the aging treatment process on the mechanical properties and microstructure of the Ti-12Cr material as a substitute for cheaper titanium implants. In this research, a solution treatment (ST) heat treatment was carried out at 885oC and an aging treatment (AT) at 5400C. Aging treatment is carried out with variations in holding time of 30 ks and 60 ks. Then the microstructure inspection and mechanical properties testing are carried out through hardness and tensile tests. With the aging treatment of the microstructure of the material, Ti-12Cr experienced grain refinement and the hardness obtained was higher than that of Ti-6Al-4V. The hardness values of Ti-12Cr ST, Ti-12Cr AT 30 ks, Ti-12Cr AT 60 ks and Ti-6Al-4V are 457 VHN, 605 VHN, 772 VHN, and 349 VHN. However, the tensile strength of Ti-12Cr is lower than the tensile strength value of Ti-6Al-4V.

Antimicrobial and anti-diabetic of Curcuma mangga Val properties have attracted research interest. Curcuma mangga Val extract (CME) and polyvinyl alcohol (PVA) were blended, and fabricated to the fibrous membranes by the electrospinning method. The effects of CME concentration on the fiber morphology and tensile properties of CME/PVA membranes were presently studied. Scanning electron microscopy (SEM) of the membranes revealed bead-free fibers with straightly/continuously orientation formed in all CME/PVA membranes. The average fiber diameter increased from 186 nm to 297 nm with the CME concentration from 0 to 3 wt.%, respectively. The addition of 1% CME resulted in relatively high tensile strength 24.96 ± 0.20 MPa, which is the highest among the CME/PVA membrane specimens. However, very high tensile modulus and low elongation showed in these results lead to reducing the functionality of the CME/PVA fibrous membrane due to the brittleness. The CME properties may contribute to those shortages.

The use of a dispenser at the office is not as frequent as at home, because it is only used during working hours or at certain times. The use of dispensers must be in accordance with established health standards, so the quality of water produced by the dispensers must also be hygienic and free of germs or bacteria. Generally, water dispensers are operated for 24 hours, meaning that the dispensers use up a lot of electrical energy. In addition, the use of dispensers must also comply with established health standards, so the quality of the water produced by the dispensers must also be hygienic and free of germs or bacteria. Meanwhile the quality of the water produced by the device cannot be monitored. To overcome this problem, a study was conducted by designing a hygienic and energy efficient water dispenser design by applying a forward scheduling approach. The design is carried out through several components, namely ultraviolet (UV), dispenser heaters, Arduino Uno sensors, DS18B20 sensors, HC SR-04 sensors, DC pumps, 2 relays, and RTCDS1307. The results of this study indicate that the dispenser heating system can work based on a set schedule by applying an advanced scheduling approach referring to the RTC DS1307 time reading. The UV lamp can be lit for 10 minutes to sterilize the main container of the dispenser with an estimated suppression of E. Coli bacteria about 87.5 colonies / minute. This system is able to suppress the growth of bacteria about 875 colonies for once lighting. This system can control the quality of water that is safe for consumption and saves electricity energy up to 79.87 kWh per month.

Intensive promotion to use renewable energy based on concerns of fossil fuel reserves depletion as the main source of world energy, by the various benefits obtained by utilizing, and then supported by advances in generation technology: causing various parties to divert the type of fuel for their energy use activities. The same thing happens to residential electricity consumers, driven by the advantageous of electricity which offers the ease of power generation that can be done on the consumer side, independent operation, reliability and quality of power, then in various places consumers try to install renewable energy based generation such as photovoltaic system for their needs of electricity supply. However, looking at the tariff structure of utility electricity and considering the investment needed: building a photovoltaic-based supply system is not necessarily the right choice. This paper presents a technical design to meet the energy needs of a residential load through an off-grid photovoltaic system. The technical basis for designing the system and the capacity of its constituent components is explained, as well as the analytical techniques carried out to assess the financial aspects of the development and operation of the system. Furthermore, a case study was carried out by designing an off-grid photovoltaic system for a load characterized by a daily load curve, from which the capacity and costs incurred to realize the system were obtained. Financial analysis is then carried out by looking at the extent to which the designed system can provide comparable benefits if the electrical power supply is carried out from the utility at the prevailing price, as well as how long the system must be operated in order to obtain a breakeven return on investment. From this, it is known that without compensation for the generation and use of renewable energy, in the current condition of the energy price, financially the system that was designed has not provided better benefits compared to if the power supply is provided from the utility.

Wireless Sensor Network (WSN) is likely to be implemented as a long-range transmission network for sensor data to detect potential natural disaster like flood, landslide, and soil liquefaction. The sensor parameters: for example rainfall, soil humidity, vibration, type of soil, and so forth were sent from the location at which natural disaster potentially occurs and were forwarded to data center in real time for further analysis and observation. Therefore, the natural disaster which potentially occurs in the area was easily detected by the parameter of nodes that were gathered in server. When sensor detected the sign of natural disaster, the information would be conveyed through WSN to information center and was broadcasted to society as an early warning of natural disaster such as flood, landslide, soil liquefaction, etc. Such information was automatically broadcasted to society and was adjusted to the impending circumstance e.g. secure, cautious, and warning. By the implementation of WSN technology as an early warning system, it is expected to information concerning natural disaster is broadcasted accurately and rapidly to society, hence society can take quick action and response to natural disaster.

Sugar cane is one of the agricultural products that are widely grown in Indonesia and most of it is used as raw material for making sugar, the alternative to fulfill the needs of sugar, one of which is brown sugar. Most of the brown sugar found in the local market was various and can be seen from the physical color, impurities, and hardness. The quality variation can be caused by several things such as variations in raw materials and inconsistent processing conditions. In processing of brown sugar should be considered the things that cause a decrease in the quality of brown sugar. The formation of the color of brown sugar one of which depends on the condition of pH of sugar juice. If pH of sugar cane juice is low it will cause a decrease in the quality of the brown sugar, most of the brown sugar produced is blackish brown and easily soft. The right pH, which is 5.5 - 6.5, will produce brown sugar with a reddish-brown color. The treatment of the combination of the pH of sugar cane juice and the different ripening process had a very significant effect on the color quality of brown sugar

Nowadays, self-laundry kiosk service has been widely available in Malaysia. Although the technology has been progressing rapidly especially the technology of Internet-of-Thing, most of the systems used by the self- laundry machines are outdated. One difficulty faced by the owners of the self-laundry kiosk, they need to check frequently by themselves at their cashbox machines in order to check whether the cashbox filled or emptied. This leads to inefficiency and can be addressed if self-laundry machine is integrated with Internet-of- Thing technology. Thus, this project attempts to improvise the current system by developing the bill acceptor that gives the owner to monitoring the flow of current amount inserted by customer in real time by displaying it in apps at owner smartphone. The project uses Arduino Mega as a controller, bill acceptor machine as token receiver, Wi-fi module to send the data to apps, LCD and Blynk apps to display the current amount and Bluetooth module to communicate between the Arduino and the washing machine. A checklist analysis and scenario analysis are implemented to verify the functionality of the proposed prototype. The result shows that the proposed prototype achieves all the objectives required.

The Indonesian Composite Stock Price Index is an indicator of changes in stock prices as guide for investors to invest in reducing risk. The classical regression model with fluctuations in stock prices tends to violate the assumptions of normality, homoscedasticity, autocorrelation and multicollinearity. This problem can be overcome by modeling the Composite Stock Price Index by using the artificial neural network (ANN) and nonparametric regression of multivariate adaptive regression spline (MARS). In this study, the time series data from the Composite Stock Price Index starting in April 2003 to March 2018 with its predictor variables are crude-oil prices, interest rates, inflation, exchange rates, gold prices, Dow Jones price, and Nikkei 225 Index. The both methods give better goodness of fit, where the coefficient of determination ANN is 0.98925 and the MARS determination coefficient is 0.99427. While based on the Mean Absolute Percentage Error (MAPE) of ANN was obtained 6.16383 and the MAPE value of MARS is 4.51372. This means that the ANN method and nonparametric MARS regression method have good performance to forecast the value of the Indonesian Composite Stock Index in the future, but the nonparametric MARS regression method shows the accuracy of the model is slightly better than ANN.

In this study, an electric wheelchair that combines two controls: joystick analog and voice control is designed. IC MCP3008 is used to navigate wheelchairs by using Josytick, where joystick analog data will be converted into digital data. The movements resulted from the joystick analog on the xAxis axis (horizontally) are the right turn and left turn, and on the yAxis axis (vertically) are forward and backward. The movements on the yAxis and xAxis axes set by the user affects the speed of the wheelchair. Meanwhile, the AMR-Voice application on Android is used to navigate wheelchairs by using sound. There are five commands in this voice control: "Forward", "backward", "left", "right", "stop". The order will be sent to Raspberry Pi 3 via the HC-06 module to then be recognized for the command. If the voice commands are received accordingly, Raspberry Pi 3 will provide an activation signal to the motor driver to move the wheelchair in the direction corresponding to the command given by the user. Voice control testing on wheelchairs is tested in quiet rooms and noisy rooms. The results of the wheelchair control testing with sound indicate that the accuracy and speed of the wheelchair response rely heavily on Internet connection and room conditions. The average response when the condition of the room is quiet is 0.16 s and when the condition of the room is noisy is 5.18 s. Wheelchairs with joystick control and the voice made can be used for the disabled, whether for those who can move their fingers or not, at a low cost so that they can be an alternative in developing countries.

*-
Food corps, especially rice, are important commodities. Rice is the main focus on achieving food self- sufficiency in Indonesia in 2017. The position of rice as the staple food of Indonesian people since 1950 is increasingly irreplaceable even though the government has intensified food diversification program. It is seen that in 1950 the consumption of National rice as a source of new carbohydrates was around 53% but in 2011 it had reached 95%. Since the demand for rice continues to increase resulting in reduced rice supply and unstable prices, rice import is a government policy to exteriorize the condition of food security. Indonesia must reduce it is dependence on imports through new self-sufficiency. The aim of this study is to predict the amount of rice production in Indonesia by 2018 by comparing fuzzy methods and multiple linear regression. It will also analyze what factors influence the rice production to see the target of rice self-sufficiency achievement in Indonesia.

The current control system is a necessity in everyday life. Security in the room or location is ideal if the room has direct control. But the limited time and energy that must be ready at all times to control a location or room makes someone unable to control. The problem that often occurs in the community is the theft of vehicles lined up at homes or campus parking locations. One solution is to control using an IP camera that can monitor any location or room at any time. Advances in technology have an impact on increasing energy needs. CCTV is a monitoring device, but it is expensive at the cost of electricity or network installations, and the limited mobility of device placement makes the use of this device not optimal. This study offers an alternative solution to overcome the above problems, namely technology-saving technological devices, raspberry Pi (RPi). From these problems, the research carried out aims to create a remote-based IP camera control system for wireless processing of image plates of sound output vehicles using Raspberry Pi as a mini PC. This study made a vehicle license plate identification system by processing sound output images using Optical Character Recognition (OCR). The plate image identification system uses IP camera control via a router.

This study aims to explore and assess the performance of a waqf institution i.e. the West Sumatra Muhammadiyah Waqf Board (BWUMSB). In doing so, this research employs dimensions of performance measures which encompass efficiency, effectiveness, maqashid al-shariah, and sustainability and growth as well as the concept of ta'bidul ashli wa tashbilul manfaah. The findings show that BWUMSB does not apply any indicators to assess the performance of its institution. It is also indicated that the revenue earned from managing waqf funds are mostly allocated for administrative expenses. Moreover, although the collection of waqf funds has increased throughout the year, the nazhir (waqf manager) tend to invest the fund into low-risk businesses, which in turn, causes profits to be suboptimal. These imply that BWUMSB has not been efficient in managing waqf funds for programs and operational costs. On the other hand, the accumulation of funds that increases every year is an effective indicator of BWUMSB in collecting waqf funds. From the perspective of maqashid al-sharia, the BWUMSB has been trying to be in line with Islamic law. The sustainability and growth dimension indicates that there have been some efforts made by BWUMSB to sustain its institution and the management of waqf funds. Overall, nazhir at BWUMSB strives to safeguard the waqf property and its sustainability benefits which is suggested by the concept of ta'bidul ashli wa tasbilul manfaah.

The purpose of this study is to examine spiritual leadership outcomes in terms of voice behavior and obedience or compliance using 244 Indonesian valid samples. In fact, that comprehension of the influence of leadership behavior on employees’ cognition, attitude and behavior is considered critically important by scholars, however there are still research gaps existing in how spiritual leaders influence their employees’ obedience/compliance and voice behavior. Surprisingly, the results show that although spiritual leadership and mediators of calling and membership are significantly inter-correlated each other, yet these five variables have non-significant correlations with employees’ obedience and voice behavior. The influence of spiritual leadership process across cultures, especially toward voice and obedience behavior is not supported in this study. Possible explanations could be related to the cultural characteristic of employees of these particular samples.
