This research is done in Totabuanvillage, district of Lolak, Bolaang Mongondow regency, using experimental methods withdescriptive analysis of the formation of biogas using biodigester technology with a permanent12 m3 dome-type reactor. Biogas started forming on the 9th day, up to the 26th day, with 12m3 of raw materials, which is a 1:1 mix of cow feces with water (6 m3 cow feces and 6 m3water), and yielded 4,68 m3 of biogas that can be used to cook for 12,3 hours. Each 1 m3 ofbiogas can be used to cook for 2,63 hours. Biogas yield is 39%Keywords: Energy, Renewable, Biodigester, Biogas.]]>
