【 摘 要 】

Village's self-fulfillment of energy supply is a new concept being developed in Indonesia. Villages are expected to meet their own energy needs without relying on fossil-fuel and other non-renewable energy materials. The concept of village's self-fulfillment of energy here includes two types of provision: the provision of electrical energy and the provision of bio-fuel by utilizing environmentally friendly renewable energy. Biogas is an alternative energy sources produced by anaerobic activities of organic materials such as human and animal feces, or domestic waste in rural communities. In general, rural farmers have 2-4 cows. It is assumed that cows/cattle produces ± 15 kg feces/head/day. A digester with 4m3capacity potentially produces bio-gas per day that reaches 1.34 m3equivalent to 6.30 kWh/day. This volume of bio-gas can be used for lamp lighting of 60-100 watts for 8 hours. Other applications that can be utilized are biogas stove. A family of farmer can use 2 stoves to cook 3 food recipes for 8 people and a generator for 1 hour. There is also potential solid mud of 40 kg that produces 8 kg of compost/day and potential sludge fluid as much as 160 liters including bio-urine of 32 liters/day. This paper discusses about the potency of small biogas digester application for village's self-fulfillment of energy supply.
