This research aims to study and compare the quantity of bio-gas from the fermentation of the timber code, and join the pigs. In this research, a random trial plans forever The independent variables used in the study is that the materials used in the fermentation process, consisting of a timber and cattle manure, together with the timber with the pigs. Make a 3 times amount of fermentation 7 days trial results found. 1. bio gas quantities that result from fermentation I found that fermentation the timber code join 5 cm3 is equal to 278.55, and marinated the pig manure, together with the timber is equal to 6, 592.82 cm3. 2. the gas of the timber with the pigs caught fire as gas quality minutes and 11.74 obtained from fermentation of natural rubber blade with a long completion of combustible gas to 8.83 minutes derived from the fermentation of natural rubber blade with the pigs, heat consumption of fermented 30.93 join kJ, timber and cattle, the heat consumption of fermented 25.91 kJ.
