Abstract. This research aims to estimate the emission of CH4 gas from the utilization of biogas technology as a source of alternative fuels and biogas has an influence on the economic condition of the society of Ploso Ngamban Village, Kendal, Ngawi East Java who has been utilizing biogas. Ploso Ngamban Village, Kendal, Ngawi East Java is one of the villages with the most populations as cattle ranchers and has been utilizing cow dung as a biogas. In cow dung, there is a CH4 gas that contributes 3% of the total greenhouse gas emissions. There are 32 cows that have been utilized to 18 units of biogas, if used maximally, it is able to reduce the emission of CH4 gas by 1,952 kg or it helps to reduce the CO2e gas emissions by 48,800 kg/year of emissions for the district of Kendal, Ngawi East Java. So if the use of cow dung into biogas is done to the fullest, it will get the efficiency of lowering the cost of CO2e gas emissions processing in Ploso Ngamban Village, Kendal, Ngawi East Java by Rp 23.424.000/year. Calculation method is based on the calculation of greenhouse gas emissions, using the formula quoted from the Ministry of Environment of the Republic of Indonesia, namely GHG emissions = Ai x EFi.
