Abstract:
Utilization of farm waste as an alternative energy source is a form of farm waste management, but field applications are not optimal. The purpose of this study is to find out to what extent the dried dairy cow feces can function as a biogas substrate for an overview of the number of anaerobic bacteria, the volume of bio-gas, and the use of organic carbon-containing biodiesel mud so that it can be used as an organic soil fertilizer. This study uses an experimental research method and looks at the results of an independent T test with two treatments: sundry and dry oven. The tests were done on days 0 (after 4 hours), 7, 14, 21, and 28. The water level, number of bacteria, volume of gas, and pH and organic C content of the biogas sludge were all recorded. The study's findings showed that the number of anaerobic bacteria on days 0 (after 4 hours), 7, 14, 21, and 28 and the amount of biogas on days 14 and 21 did not change whether the samples were dried in the sun or in a furnace. However, on days 7 and 28, the amounts of biogas changed depending on whether the samples were dried in the sun or in a furnace.
