Abstract

Anaerobic digestion is a break-down process of animal wastes or municipal wastes to produce biogas. The process involve microbial activities in the feedstock without the presence of oxygen. The resulted microbial activities is usually called as bioenergy, contain mostly methane gas with carbon dioxide and some other traces gases. Methane gas is a valuable gas that can be used a source of energy, either used for cooking fuel or small-scale electricity production. The most suitable application of the methane gas is in rural area which rarely have the source of energy. It can reduce the dependency of using diesel or gasoline in order to obtain electricity.This thesis focuses on the use of dairy manure as the feedstock and the rumen fluid as the innoculant which can improve the production of biogas. The amount of rumen fluid and water added were varied to create 0 %, 12.5 %, 25 %, 37.5 % and 50 % rumen fluid. Besides that, the pH level also been monitored and its effects towards biogas production is discussed. From the experiment that has been conducted, sample with 37.5 % rumen fluid gives the highest biogas production, followed by 50 %, 25 %, 12.5 % and 0 % rumen fluid.
