SOCIALIZATION OF PKM EDUCATES UB BOSS FARM FARMERS IN MAKING BIOGAS AS ENVIRONMENTALLY FRIENDLY RENEWABLE ENERGY FOR TOFU PRODUCTION

Biogas is a gas produced from the process of decomposing organic materials by microorganisms under anaerobic conditions. Biogas can be burned like LPG and become an alternative source of renewable energy that is environmentally friendly. Biogas contains 60% CH4 gas (methane); 38% CO2 gas (Carbon Dioxide); and 2% N2, O2, H2, H2S gas. The name of the partner is UB BoSS Farm with a business as a Cattle-Buffalo Farmer as well as producing tofu which is located in Cibadak Village, Ciampea District, Bogor Regency. The number of cows is 40 and 2 buffaloes, so that the potential for wet waste produced is 420 kg/day which is equivalent to 117,600 liters/day of biogas; solid total of each tail is 16% and solid volatility is 77% TS. The stages of implementing PKM activities that have been carried out include discussion, socialization, and evaluation of activities (pre-test and post-test). The results of PKM activities showed a change in the level of knowledge of participants regarding what factors were influential, and the stages of the biogas manufacturing process from 20% to 93.33%. The post-test results also showed that most of the participants (86.67%) now have knowledge about raw materials around the business area that can be used as biogas.
