Biogas energy is one of the non-fossil fuels or renewable energy sources as well as bioenergy alternatives because it is obtained from livestock manure, organic waste, and other food industry wastes. Biogas is obtained through a fermentation process with the help of microorganisms.Organic waste is organic material which could be seen as disturbing and as a source of environmental pollution, and smells not good if people waste carelessly, also it happens in dregs of fermented soybean and water plants as hydrilla verticillata. This research aims to exploited materials of organic waste, dregs of fermented soybean (tempe), hydrilla verticillata become alternative energy that is biogas. Based on the physical character and composition of the organic mater, the anaerobic processing used in making this biogas. Anaerobic processes are the decomposition of organic matter by activity without oxygen. The variable whose effect biogas is environment factor such as water quality and nutrition factor that is C/N ratio. Accordingly, the process to produced the best biogas are made by any mixed variation between organic waste material combined dregs of fermented soybean and hydrilla verticillata namely (90:10; 80:20; 70:30; 60:40; 50:50) in reactor volume 6 liters and processed 15 days with batch system. The results showed that the best biogas producted by mixed variation between organic waste and hydrilla verticillata (90:10) in the amount of water quality 21,71% and C/N quality ratio amount 24,38% conducted quality methane amount 58,37%.
