UJI TEKNIS BIOGAS DARI BAHAN BAKU FESES SAPI DI DESA TOTABUAN KECAMATAN LOLAK KABUPATEN BOLAANG MONGONDOW

Abstract

ABSTRACT
Energy is a crucial global issue. Demand for energy increases every year. According to
data collected by the Ministry of Energy and Mineral Resources (2006) Indonesia’s oil
supply amounts to a mere 9 billion barrels, which will run out with continued consumption.
To decrease dependency on fossil fuels, the government has issued Peraturan Presiden
Republik Indonesia number 5 year 2006 about National Energy Policies to develop
alternative renewable energy resources. Energy experts around the world are now researching
and developing renewable energy, one of which is biogas. This research is done in Totabuan
village, district of Lolak, Bolaang Mongondow regency, using experimental methods with
descriptive analysis of the formation of biogas using biodigester technology with a permanent
12 m3 dome-type reactor. Biogas started forming on the 9th day, up to the 26th day, with 12
m3 of raw materials, which is a 1:1 mix of cow feces with water (6 m3 cow feces and 6 m3
water), and yielded 4,68 m3 of biogas that can be used to cook for 12,3 hours. Each 1 m3 of
biogas can be used to cook for 2,63 hours. Biogas yield is 39%
