Pengaruh Limbah Batang Pisang (Musa Paradisiaca) Dan Jerami Padi (Oryza Sativa L.) Terhadap Produksi Biogas

Abstract

Biogas is a natural gas consisting mainly of gas metane (CH4) and carbon dioxide (CO2) produced from the anaerobic (without oxygen) fermentation of organic matter by methanogenic microorganisms. This process occurs in the biogas digester as a place for reactions by microorganisms to occur. The aim of this research is to increase household scale biogas production. The method used was a 2x2 Factorial Randomized Block Design (RBD) with 3 replications. The procedure in this study used chopped rice straw and banana stems and then put them into the digester and calculated the volume of gas formed using balloon media. The addition of 50 grams of rice straw with 100 grams of banana stems produced biogas with an average volume of 1531.24 mm3. The addition of 100 grams of rice straw and 100 grams of banana stems average volume of 2143.15 mm3. The addition of 200 grams of rice straw and 50 grams of banana stems has an average volume of 1170.28 mm3. The addition of 200 grams of rice straw and 100 grams of banana stems has a volume of 808.28 mm3. Control of biogas containing 500 grams of livestock manure with the addition of 500 ml of water has a volume of 852.95 mm3. In accordance with observations for 7 days, the best results were the addition of 100 grams of rice straw and 100 grams of banana stems for 3 repetitions with an average volume of 2143.15 mm3.
