Biomass or biogas is one of the alternative technology in terms of energy that comes as an answer to solve the problems in society due to the increase of price oil. This technology could be applied as soon as possible, especially for those who have a cow farm sanctuary. In order to fulfill the need of home supply energy, a program called Bio Energi Pedesaan (BEP) comes as a sollution. This program is aimed to maximize self production of energy by society especially those who are in the rural areas. Incapability of handling the cow dung as the alternative energy to substitute woods and gas oil was quite serious problem where their daily activities were really depending on gas oil and woods ranging from cooking to the device of lighting. As a sollution, the device that designed as biogas digester made from 200, 120, and 35litres capacity of drum were made. Also PVC pipe by the size of 2inch and 0.5inch which are easy to get. The assembly of this device is including the cutting process, welding, grinding, and then casting using cement. Every 1 cow could produce the average of 20kg in a day, which equals to 1 m3 – 1,2m3. In the process of calculating the amount of methane gas that could be produced from 20kg of cow dung per day, resulting the mixed methane gas of 0.10285kg and fine methane gas of 0,061714kg.
