摘要：Processing of agricultural and livestock waste produces biogas which is then used by the community to substitute natural gas energy and substitute electricity for clean water supply and produce organic fertilizer for farming purposes. This research was conducted using descriptive methods, by describing how to treat agricultural and livestock waste. Then a quantitative approach is used which aims to describe or explain the conversion of biogas energy into electrical energy. Biogas has good prospects as an alternative energy substitute for non-renewable energy in Indonesia which is experiencing an energy crisis which is characterized by increasingly scarce and high fuel prices which have an impact on the higher costs of generating electricity. In the Ganjar Farmers-Farm Group, the use of biogas by using goat / sheep dung is very potential, from 300 goats / sheep has the potential to produce electrical energy of 32.4 kWh / day. Most of the power plants that supply the Pati Regency region still use energy sources made from non-renewable energy materials. The depletion of fuel for these non-renewable plants, power plants with renewable fuels are absolutely necessary.
