Semi portable biogas power plant using engine generator set for disaster area

This paper aims to find out the potential of a biogas power plant system using generator sets as an alternative energy source in disaster areas. Indonesia is a country at risk of experiencing a disaster based on World Risk Index data for 2014-2016. The Palu Earthquake shows that electricity is an important necessity during a disaster. Based on BNPB regulation No. 17 of 2009, generator sets are needed as units of electricity generation in disaster areas. Biogas can be an alternative power plant in the area. The research method used to determine the appropriate biogas treatment method. Variation of fuel and loading, engine capacity is carried out to determine the performance of the generator. Obtained biogas production will be optimal after 10 days of biomass retention, 90 minutes of purification of vapor in bag absorbent. The 1 kW generator set was tested using gasoline and biogas with a load of 200 W, 400W, and testing a 3 kW generator using methane gas with a load of 400 W, 750W, 1000 W, 1500 W. high, namely methane gas, biogas and gasoline and the thermal efficiency of a 3 kW generator set is higher than 1 kW. Active power per load produced by a 1 kW generator and 3 kW generator is relatifly the same.
