B Breeders and farmers in Cibodas Village has facing a trouble with a disposal of cow dung and vegetables waste. The waste is disposed into the rivers or abandoned land and it causes an environmental damage. An alternative that being used to processed the cow dung and vegetable waste is biogas technology, which put the waste into the reactor then the biogas effluent can be used for electricity and cooking. This research objective is to the characteristics of cow dung and vegetable waste, finds out the amount of gas production which is produced from the mixing process of cow dung and vegetable waste as well as the influence of pH, temperature and other parameters of the anaerobic process on biogas. This research used a raw materials of vegetable waste which obtained from and cow dung from livestock. This reaserch used five variations of raw materials called P1 with 100% ratio of cow dung, P2 with 100% ratio of vegetable waste, P3 with 50:50 ratio of cow dung and vegetables waste, P4 with 75: 25 ratio of cow dung with vegetables waste and P5 with 25:75 ratio of cow dung and vegetables waste. The research was conducted for 70 days and used a reactor from a used gallon with a capacity of 19 liters. The measurement parameters consist of temperature, pH, Total solid (TS), Volatile Solid (VS), C/N ratio, Chemical Oxygen Demand (COD), Volatile Fatty Acid (VFA), and Biogas Volume. The biogas measurements were carried out on 30th and 60th days. The results shows the variations in P1 that produced methane gas on the 30th day as 41,91% and on the 60th day as 37,9% with a total solid of 7,34%, volatile solid of 85,6%, C/N ratio of 36.73%, which concluded that the reactor in this variation is the most efficient reactor among the other variations.
