Biogas Production from Co-Digestion of Goat Manure and Watermelon (Citrullus Lanatus) Fruit Peels Under Anaerobic Condition

Abstract:

Biogas is an alternative source of energy that is produced by methanogenic bacteria through the bio-degradation of organic material under anaerobic conditions. In this study, biogas production from co-digestion of the goat manure (GM) and watermelon peels(WMP) in five mix ratios were evaluated under 38ºC using batch fermentation. In all treatments, physico-chemical parameters such as total solid (TS) and volatile solid (VS), organic carbon, and pH were measure before and after digestion. The daily biogas production was subsequently measured by water displacement method for 27 days. All measured of physicochemical parameters of each substrate significantly varied (p
