This research aims to study the biogas generated by the fermentation of food waste. The production of biogas in the tank with 200 liters at the start of the operation put cow manure as inoculum ratio, 50 kg and 50 kg marinate for 15 days, then take the debris with a ratio of 1: 1 Scraps 1 kilogram of water one. Kilograms added to the fermenter continuously every day. 30 day fermentation period, the removal efficiency of organic substances is between 36.36 to 96.97 percent, effective removal of organic compounds, up 96.97 percent from the fermenter pH in the range of 5.91 to 6.84 gas formed by the machine. Gas counter the principle of water displacement. The study found that Biogas generated an average of 17.93 liters per day and the amount of biogas highest accumulation of 537.80 liters per day of gas per barrel of 120 liters Energy LNG have 15 minutes.
