Study of biogas energy potential from pig waste of Pelambian Hamlet, Salusopai Village, North Toraja district

Abstract

National energy sources still rely on non-renewable fossil-based raw materials, so new breakthroughs are needed to develop renewable energy such as biogas. This study was carried out in Pelambian Hamlet. Salusopai Village. North Toraja Regency with the aims to analyze the potential and benefits of biogas energy development from pig waste and formulate its development strategy in Pelambian Hamlet. Data collection was carried out through questionnaires to the residents of Pelambian Hamlet. Salusopai Village to find out the information of livestock and energy needs. The development of biogas energy can used to replace the fossil fuels and the substitution of LPG energy into biogas has benefits the economic ad environment which reduces the impact of pollution from pig waste and produces fertilizer from waste that has gone through the fermentation process. The calculation of biogas energy potential is based on the dry matter content of pig manure. The obtained result demonstrated the biogas energy potential is 9.17 m3/day or equivalent to 4.22 kg LPG/day. The strategy to develop biogas energy from pig waste is to build biogas installations, optimize the use of slurry as fertilizer, build concrete fixed-dome digesters, optimize existing pigs, maximize absorption of DAK in accordance with existing regulations, conduct socialization and training in making biogas installations, making and strengthening a group of pig farmers in Pelambian Hamlet.
