Kajian Kinerja Mesin Genset Berbahan Bakar Campuran Biogas-Pertalite

Abstract

Energy plays an important role in supporting various human activities every day. One promising energy solution to reduce dependence on fossil fuels is biogas, which can be an environmentally friendly alternative. This research aims with the addition of biogas fuel mixed with pertalite oil on carburetor modification to get savings in fuel consumption rates. This research uses a 2 Factorial Completely Randomized Design (CRD) with 3 replications. The first factor is based on variations in biogas flow rate (V) consisting of V1 = 0 L/minutes, V2 = 0.5 l/minutes, V3 = 1 l/minutes, V4 = 1.5 l/minutes. The second factor is based on the variation of operating time on the dual fuel system generator engine (T) consisting of T 1 = 5 minutes, T 2 = 10 minutes, T 3 = 15 minutes. The results showed that the purification of biogas as much as 270 L to be used on a biogas-pertalite-fueled generator engine at a biogas flow rate speed of 1.5 L/minutes with a length of operation on the generator engine for 5 minutes can save fuel oil pertalite 6.47 mL/minutes or 45% and increase the output power of the generator engine from 391.02 W to 420.23 W with engine torque 1.32 Nm. This study shows that a mixture of biogas and pertalite can operate a generator with carburetor modification, improve performance, and save fossil fuels.
