ANALYSIS OF MIXTURE OF COW MANURE AND ORGANIC WASTE ON BIOGAS PRODUCTION IN BATCH-TYPE DIGESTER

Abstract

Biogas is an alternative energy that can be utilized by the community, especially in rural areas with a variety of mixed materials that are easily obtained. Various alternative biogas mixtures have been developed by researchers for the feasibility of the quality of the biogas produced. Various mixtures of biogas-forming materials were researched and developed, according to the level of need. Therefore, this research is an analysis of the form of biogas that focuses on a mixture of cow dung waste with organic waste. There are three comparison compositions tested. The first composition ratio is 50 kg: 5 kg (cow dung with organic waste), the second ratio is 40 kg: 15 kg and the third ratio is 30 kg: 25 kg. The data obtained that the best test results in the third test were with a composition of 30 kg: 25 kg. The total composition of the mixture of cow waste and vegetable waste greatly affects the biogas production produced. The digester used in the study used a batch type. Each mixture composition was tested 3 times to get valid results.
