Fossil fuels are conventional sources of energy that in their use cannot be renewed and over time will deplete. Therefore, it is very important to take advantage of renewable energy sources that come from nature and can be renewed. An alternative to fossil fuel is biogas. In this study, the raw material of biogas production is chicken manure waste which is mixed with cow manure and dragon fruit peel. This study aims to know the nature and characteristics of biogas produced from chicken manure waste and the changes in Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels in the waste mixture used after the process of making renewable energy. The best composition of chicken manure waste, cow manure substrates, and dragon fruit peel waste for biogas production is also investigated. Biogas is obtained by mixing all raw materials into the digester tank for 21 days, with a pH value range of 7.0 – 7.2 and temperature conditions between 20-40 °C. Analysis using Gas Chromatography shows that the highest methane gas value of 46.79% is obtained at a composition of 80: 10: 10 (wt. %) for chicken manure, cow manure, and dragon fruit peel, respectively. Furthermore, the highest heating value is obtained at this composition, namely 25,965 kJ/kg and 22,725 kJ/kg for High Heating Value (HHV) and Lower Heating Value (LHV), subsequently. The results indicate the potential use of a combination of poultry and fruit waste for biogas production.
