With the increasing need for motorized vehicles every year, the increasing need for fossil fuels is needed. Of course, this can lead to a significant imbalance between the number of motorized vehicle users and the number of available energy reserves, besides that it can affect how the air quality in the country and the city. This writing uses using qualitative literature study methods. The author collects data with observation techniques. The results of this paper concluded that the Jatropha plant has a role in a sustainable economy. This is because fence distance has properties as renewable energy, jatropha also has several other economic benefits.

Abstract
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.
