Biogas generation commonly utilize the organic waste such as cattle manure, food waste, agricultural waste, and human waste. This cause biogas considered as a potential waste-to-energy technology which greatly contribute in reducing environment pollution and the most important in reducing greenhouse gases effect caused by the waste. Utilization of raw material such as human waste (human excreta) considered beneficial in terms of the process because it does not require additional starter (microorganisms seed), and a supply of microorganisms occurs continuously during the feeding of raw materials. This directly supports the sustainability of the production of biogas
