Biogas efficiency from cow dung waste in strengthening energy security during the covid-19 pandemic through a dynamic modeling system

Abstract

During Covid-19 pandemic, the increase in LPG types was 0.6-2.4 million BOE, while in the household sector it was 2.3-6.9 million BOE, so causes LPG import growth ratio to increase by 4.8%/year (BPPT, 2020). Therefore, it is necessary to make efforts to suppress LPG imports by increasing the supply of EBT in the household sector with biogas production. The research aims to look at the biogas production modeling system from the resulting cow dung waste. The research method that studies the literature is based on modeling data based on data obtained using Powersim 10. The results showed that LPG demand in 2020 is 2.4 million BOE that could be fulfilled by a biogas source from 9539238.75 kg ~ 0.9 metric tons cow dung waste. This cow dung waste is able to produce 381569.55 m³/kg of methane gas which is equivalent to 0.59 metric tons LPG, savings Rp 690 M; 103 million liters gasoline, savings Rp 793 M; 64.8 million liters diesel fuel, savings Rp 333.8 M; 80 million liters kerosene, savings Rp 1 T; 4.53 metric tons wood, savings Rp 4.5 T. This favorable situation must be immediately felt by the community with an estimate of future benefits.
