Type: conference-paper
Abstract: The objective of this study is to produce biogas from livestock manure, water hyacinth and tempeh liquid waste which is actually dangerous for the surrounding environment. Water hyacinth has a high hemicellulose content, while animal waste and tempeh liquid waste can produces CH4 gas even the BOD and COD values are quite high. By using anaerobic digestion method, we will convert the material into methane gas. This research took a total of 28 days with by using other materials also such as NaOH, H2SO4, stater, aquadest. After conducting research, the most optimal results for the total biogas volume were obtained by variable A5 (86.63% cow dung: 4.70% water hyacinth: 8.66% tempeh liquid waste) with total volume of 2360 ml and the highest amount of methane/CH4 gas is obtained by A6 (86.63% cow dung: 4.70% water hyacinth: 8.66% tempeh liquid waste) with a value of 830581.83 ppm. While the lowest CH4 shows by variable A1 with total amount of 209601.39 ppm. This shows that water hyacinth is not sufficient to increase the potential amount of biogas produced.
