Analysis of Biogas Yield From Organic Waste (Vegetables, Cassava Peels And Banana Leaves)

Abstract

Until now, waste remains an unresolved issue; however, there is an effort to address the waste problem by utilizing it to produce biogas. Biogas is considered one of the renewable energy sources, as it can be derived from organic waste originating from markets, cooking leftovers, animal manure, and other waste materials. The purpose of this research is to analyze the biogas yield from various types of organic waste as an alternative source of biogas or renewable energy. The waste materials used in biogas production are cooking leftover vegetable waste, banana leaf waste, and cassava peel waste. The biogas production involves anaerobic fermentation over a period of 10 days. Biogas testing is conducted by measuring the mass of the produced biogas using a digital scale and determining the ignition time with a stopwatch. The results of this study reveal the mass of biogas produced and the ignition time for biogas from vegetable waste, banana leaf waste, and cassava peel waste, respectively. The values are 950 grams and 337 seconds, 905 grams and 83 seconds, and 765 grams and 60 seconds. It is found that the highest methane content is produced from cooking leftover vegetable waste mixed with cow dung compared to banana leaf waste and cassava peel waste.
