Abstract: Biogas is one of an alternative source of energy that is produced by methanogenic bacteria through the bio-degradation of organic material under anaerobic conditions. The aim of this study was to measure daily biogas production from mixture of fruit peels with cattle manure in solo and five mix ratios under anaerobic condition at 25°C using batch digestion under room temperature conditions (25ºC) using batch fermentation. In all treatments, parameters such as total solids (TS), volatile solids (VS), pH, organic carbon (%), total nitrogen and C:N ratio were measured before and after digestion. The daily biogas production was subsequently measured by water displacement method for 30 days. All measured of physico-chemical parameters of each substrate were significantly different among digesters before and after anaerobic digestion. Gas production was clearly observed in all of the substrates types starting from the fifth day of digestion and increase gradually and also decrease sequentially at the end in all substrates. Among all digesters, the one fed with 30% PM and 70% MFL was showed in the highest cumulative biogas and the lowest was recorded from 100% PM. The result suggested that mix ratio of the two substrates in 30% PM and 70% MFL was optimal for maximum biogas yield. Overall results indicate that the increment of biogas yield and VS, and TS reduction can be significantly enhanced when GM and WMP are co-digested. However, the quality of biogas produced was not subjected to be tested chromatographically in terms of the methane content.
