Bio gas (Biogas) is a gas that is caused by the degradation process in organic matter by bacterial species inhabit oxygen (Anaerobic) causes gas, while digestion occurs. This group is called biogas biogas consists. Methane CH4 60 – 70 percent of the carbon dioxide (CO2), 30 – 40 per cent of the remaining gas is hydrogen sulfide (H2S) and nitrogen gas (N2), where there are flammable methane properties, so can a renewable energy fuel. Such as cooking fuel, industrial fuel automobiles. Degradation of organic objects can provide biogas, but how much gas will occur. Depending on the type of organic objects such as plants, decomposition will occur on the gas harder than fresh manure, because manure is digested, by causing bacteria can degrade quickly. The plants were using the fermentation process, biogas must be compact, hack and leave before fermentation. Certifying material for fermentation. In addition, there will be a live plant and animal manure, waste or waste water from processes such as fermentation used waste water from starch can. Waste water from pig farm Scraps by household, etc.
