The main objectives of writing this paper are (1) to determine the response of breeders to the use of cow feces for making organic fertilizer, (2) to use cow feces for making organic fertilizer. The method used is counseling, training and mentoring. The response of farmers to the assisting activities in making organic fertilizer is quite high, this is shown from the evaluation results that 100% of farmers know and understand about making solid organic fertilizer from cow feces, and farmers agree to develop fertilizer manufacturing businesses. this organic in the future. Organic fertilizers can provide additional income for farmers of IDR 150,000.00 / month Key words: fertilizer, feces, fermentation, cattle, breeders Introduction Ayunan Village is located in Abiansemal District, Badung Regency, precisely between Taman Ayun and Sangeh tourism objects, 20 km from the city Denpasar, is located at an altitude of 164-240 meters above sea level and has an average rainfall of 3000 mm / year. The temperature ranges between 26 º -29 º C so the air here is cool. The topography of the flat settlement extends along the main road with building arrangements based on Balinese architecture (asta kosala kosali) and the downstream part is a rice field area (subak Ayunan) and the upstream part is a plantation (subak Abian) as the main life support for the community. In the west, the Dangkang river flows, which is the source of irrigation for the Ayunan subak and the Pendet river flows in the east. The topography of rice fields is flat and partially terraced, especially those bordering the river. The natural conditions are still beautiful, the neatly arranged rice terraces are the main attraction, and the beauty of the terraces of the Sobangan and Tegalnarungan subak rice fields with the background of the Batu Karu mountain, these natural and cultural resources have the potential to be used as natural tourism or ecotourism. Jungle tracking is approximately 1.5 km long starting from Bale Subak Ayunan to the north along the river to the Ayunan dam and then up to the leading tour of Ayunan Village in the form of honey bee farm in Banjar Geriya. After enjoying the Nyawan lawar culinary and watching the cooking demonstration of bee lawar, tourists can see various kinds of paintings at the 578 VOL 3, No.3 November 2020 ISSN: 2656-303737 http: //www.journals.segce. com / index.php / IJSEGCE DOI: https://doi.org/10.1234/ijsegce.v3i3.166 Tjok Agung Tresna Museum in Banjar Badung. Throughout the jungle tracking, tourists can see the craft of making satay katikan (for ceremonial or party purposes), face painter (Dukuh Art Studio), Pancoran dedari which is believed to cure eye diseases, the Bukit Buung temple which is a symbol of the failure of the abstract effort to expand the existing forest. at Pura Agung up to 200 meters to the southwest. Local wisdom of the community, such as wood carving, sculpting, and groups making offerings, from small to medium sized ones, are all managed by Bumdes. The majority of livelihoods for the people of Ayunan Village are agriculture and livestock in a broad sense. The cattle breeders who are members of the Simantri group process cow dung waste into organic fertilizer. The problem faced is that the tourism potential has not been utilized and developed by the people of Ayunan Village as a tourist village based on local wisdom, even though all of the community's activities have been known by local tourists but only limited to economic activities and not yet as a tourist destination. Utilization of livestock waste (livestock manure) is a very appropriate alternative to overcome scarcity and rising fertilizer prices. Farmers have optimally used manure as fertilizer in vegetable product centers. There is still manure piled up around the barn and it is not widely used as a source of fertilizer. Farmers' complaints when there is scarcity or high price of non-organic (chemical) fertilizers can be resolved by re-activating the production and use of compost. Based on this, the Karang Ayu farmer group in Ayunan village has started a business of makingorganic fertilizer solid/ compost through composting the group's cow manure. The solid feces produced around 5 kg / head / day have not been used optimally, as organic fertilizer (compost). The resulting feces smells bad and is often complained by the surrounding community. Therefore, the waste produced needs to be used as compost. Compost is a fertilizer made from the remains of living things, both animals and plants, which have been decomposed by decomposing organisms. Decomposer organisms or decomposers can be microorganisms or macroorganisms. Compost functions as a source of nutrients and a growing medium for plants. Judging from the manufacturing process, there are two ways of making compost, namely through aerobic (with air) and anaerobic (without air / fermentation) processes. Both of these methods produce equally good compost, it's just a little different in physical form. How to make compost using the anaerobic / fermentation method usually requires a microorganism inoculant (starter) to speed up the composting process. Inoculants consist of selected microorganisms that can break down organic matter quickly, such as effective microorganisms (EM4). In the market there are also types of inoculants from various brands such as superbio, probio .. If there is not enough funds available, they can also make effective microorganism inoculants by themselves Methods The methods used for the Karang Ayu livestock group are counseling, training and mentoring, in detail. are as follows: (1) counseling and assistance and management of livestock waste; (2) training and assistance in utilizing cow manure (feces) for composting. The materials needed are cow feces, rice husks, molasses rice bran, EM 4. Meanwhile, the equipment needed includes a hoe, rake, and a sieve machine. buckets, hand sprayers, tarpaulins, field shoes and other necessary equipment, the number of farmers participating in the activity of making solid organic fertilizer from cow dung is 20 people, with age ranges between 30-60 years, with an average area of land cultivated by farmers of 30 acres. To measure the success of counseling and training, before and after the activities were carried out pre-test and post-test, the results would be able to measure the success of each activity, whether the material provided was understandable or not, and whether more depth was needed from the material used. has been given to breeders. Field visits are made to livestock groups that have successfully managed their livestock business waste. The field visit was carried out with the aim of increasing the knowledge of the pig group partners in the management of special waste businesses. Results and Discussion Activity was started by observing the location of the existing sheds and places where fertilizers were made. From the results of observations, it is deemed necessary to provide counseling related to the 579 VOL 3, No.3 November 2020 ISSN: 2656-303737 http: //www.journals.segce. com / index.php / IJSEGCE DOI: https://doi.org/10.1234/ijsegce.v3i3.166 production process of organic fertilizer and continued with the Denplot. The basis for making organic fertilizers is cow dung / feces and EM 4, husks, decomposed with EM4 which triggers microorganisms in the soil plus bran to enrich the compost content, in addition to adding sawdust, or husks, rice straw can also be added with ash and calcite / lime. Cow manure was chosen because in addition to being widely available in breeders it also contains nitrogen and potassium, besides that, cow manure is good manure for organic fertilizer. The principle used in the manufacture of organic fertilizers is the process of composting organic waste into organic fertilizer through biological activity underconditions controlled. The materials needed are cow dung: 80 - 83%, sawdust (can be husk, rice straw): 5%, EM 4 microorganism booster: 0.25%, husk ash: 10% and lime: 2%. The place of manufacture is a plot of ground ground and divided into 4 parts (locations 1, 2, 3, 4) according to the size required and the place is shaded so that the fertilizer is not exposed to direct sunlight and rainwater. The manufacturing process is first the cow dung (fases) is taken from the pen and drained for one week to get a moisture content of ¬ + 60%, then the drained cow dung is moved to location 1 where organic fertilizer is made and given sawdust or husks, straw rice and ash, calcite / lime and stardec according to the dosage, then all the mixture is stirred evenly. After all the materials are used up, the next step is to cover the compost using a tarpaulin or plastic cover. Place a weight on each side of the tarp to prevent the tarp from being exposed easily and causing flies or maggots to enter. Let the composting process take place, the sign is that there is hot temperature on the surface of the compost. Figure 1 Making Organic Fertilizer After one week at location 1, the pile is moved to location 2 by stirring / flipping it evenly to increase oxygen supply and increase the homogeneity of organic fertilizers.

  • From Sacred Cow Dung to Cow 'Shit': Globalization and Local Religious Practices in Rural North India*
    1 ■ Article ■ From Sacred Cow Dung to Cow 'shit': Globalization and Local Religious Practices in Rural North India* ● Susan S. Wadley The global forces of modern capitalism are often critiqued for their power to create a homogenous world order, one that will erode the local cultures with which it comes into contact. Simply put, globalization can usefully be conceived of as the product of the "myriad linkages and interconnections between the states and societies which make up the modern world system" [McGrew 1992: 23]. Although these linkages move ideas and traditions between first world and third world, and back, the consumer culture and cultural norms of the western (Euro-Ameri- can)1) world have tended to dominate this cross-fertilization. But to be- lieve in the all-consuming power of global forces is to deny any power and agency to local cultural traditions and to the people who enact them2), to deny people's abilities to accommodate, to resist, or to reject the ide- als, symbols, practices, and goods emerging from the cultural and mate- rial 'supermarket' [Mathews 2000] of the globalization process. While there is evidence that global forces can be oppressive and lead to the erosion of cultural traditions while challenging identities, others see the processes of globalization as potentially liberating.

  • Kinetic Analysis of Thermochemical Processes for Dried Cattle Dung
    Kinetic analysis of thermochemical processes for dried cattle dung Tejas Tankaria ([email protected]) Supervisor: Prof. Francisco Lemos, Prof. Amelia Lemos, Dr. Adam Klimanek Instituto Superior Técnico, Lisbon, Portugal September 2016 Summary Cattle dung is a lignocellulosic material with high moisture and high ash content, which has the potential of energy generation or conversion. Currently, for energy conversion it is utilized in anaerobic digestion and direct combustion process. Anaerobic digestion generates biogas but has a low carbon conversion efficiency, and requires removal of hydrogen sulfide and ammonia from the biogas before use. Direct combustion is only used in developing countries as cheap energy resources for cooking and heating purposes in low efficiency stoves which causes many chronic respiratory diseases and deaths due to poor indoor air quality. Cattle dung is a cheap source of fuel which can be utilized in various thermochemical conversions to convert it into various solid, liquid and gaseous fuels, which are more efficient and high in energy density. As, the fuel has to be dried for thermochemical conversion, dried cattle dung is used for experiments. In this thesis, the kinetics of three major types of thermochemical processes; pyrolysis, combustion and gasification (partial oxidation) is studied. Ultimate and proximate analysis of dried dung is performed to predict behavior of fuel. Thermo gravimetric (TG), Differential Thermo gravimetric (DTG) and Differential Scanning Calorimetry (DSC) techniques are used to understand effect of heat rate and flow rate in thermochemical conversion processes. Cattle dung ash that results from the thermochemical processes contains a high amount of mineral matter, majorly silica.

  • The Significance of Cows in Indian Society Between Sacredness and Economy
    Govindasamy Agoramoorthy, Minna J. Hsu: The significance of cows in Indian society between sacredness and economy The significance of cows in Indian society between sacredness and economy Govindasamy Agoramoorthy Tajen University, [email protected] Minna J. Hsu National Sun Yat-sen University, [email protected] Abstract Cows are still considered holy to the people of the Hindu faith across the Indian sub- continent. In this paper, the authors discuss details of the religious, historical, economic, cultural and sociological significance of the sacred cow in Hinduism. The authors also suggest options to use the sacred cow for the enhancement of eco-friendly living in India in the near future. KEYWORDS: Hinduism, cow protection, religion, culture, economy, society, India Introduction The Hindu religion recognises the rights of animals to co-exist with humans; therefore, people are taught to love, nurture and worship them. The religion promotes the belief that various Hindu gods and goddesses incarnate in various animal forms. In the past, kings and emperors used various species of animals in their emblems to show their respect. Many festivals in India are still being celebrated to honour different animals (Agoramoorthy & Hsu 2006). From a source of milk to a provider of labour and religious inspiration, cows often play a prominent role in Hindu society. To the population of 900 million Hindus spread across the Indian sub-continent and elsewhere, the cow is a holy animal that cannot be harmed. The faith first evolved near the Indus River valley nearly 3,000 years ago; re- specting the cow remains a central theme in the daily lives of the Hindu faith even today.
