Utilization of Biogas in Generators to Generate Electricity

Abstract

Agricultural and livestock biomass waste is a potential source of basic materials in producing biogas because the organic content it has is quite high so it needs to be used in generators as engine fuel mixtures. The purpose of the research is to get the best treatment by looking at the time the generator operates and the highest electrical power produced. This research was conducted using an experimental method with 3 treatments with 3 replications, namely using a mixture of cow dung with rice straw (P1), cow dung with corn cobs (P2), and cow dung with water hyacinth (P3), and the use of biogas and LPG as generator fuel with biogas levels of 5, 10, and 15% and LPG 95, 90, and 85%. The results showed that the best biogas yield was obtained from a mixture of cow dung and rice straw (P1) with a level of 5%. Biogas with a level of 5% can turn on the generator for longer. The generator can operate for 10.10 minutes by producing 946 watts of electrical power.
