Abstract

The substantial development of the palm oil industry in Indonesia is evident in the high production of Crude Palm Oil (CPO) as the primary product and Palm Oil Mill Effluent (POME) as a byproduct in palm oil mills. POME waste contains emissions that can harm the environment, necessitating proper waste management. This issue can be addressed by transforming the waste into biodiesel, as it still contains Free Fatty Acids (FFA) and triglycerides. The utilization of biodiesel can reduce the reliance on fossil fuels and environmental pollution. The research aims to evaluate the quality of biodiesel based on the SNI 7182:2015 standard, considering parameters such as Free Fatty Acid (FFA), acid value, density, water content, and viscosity through experimental processes involving sulfuric acid esterification and basic catalyst transesterification. The study is expected to provide information on the potential of biodiesel as a vehicle fuel and energy source for colt diesel engines, along with an emission analysis during the transition from biodiesel to solar. The biodiesel produced meets the standards for FFA (0.26%), acid value (0.57 mg/KOH), and density (0.871 g/ml). The waste volume of 490 m3/day generates 5,096 liters/day of biodiesel, sufficient for 23 units of colt diesel engines with 55% efficiency, producing an energy output of 988,902.91 J. The transition to biodiesel fuel can reduce CO2 emissions by 20.4%, NOx by 50%, and HC by 40%.Keywords – Biodiesel, POME, Renewable Energy, Esterification

Abstract

Cassava production in Riau Province has bioethanol potential which is quite capable as a substitute for fossil fuels. Bioethanol is an alternative and environmentally friendly energy that can be used as a fuel mixture for generator sets. One of the highest sources of raw material for bioethanol production is the cassava plant. Waste originating from cassava dregs and peels is still not fully utilized, even though this waste contains carbohydrates which can be converted into ethanol. Based on the content derived from cassava itself, it has a starch content of 35% which contains amylose and amylopectin which can be converted into ethanol. The method used in this research is descriptive research with biochemical conversion. This study aims to determine the electrical potential generated by bioethanol from cassava waste so that it is expected to reduce the use of fossil fuels. To determine the level of ethanol produced, it can be done by simulating it in the SuperPro software. The steps taken to produce bioethanol are pre-treatment, hydrolysis, fermentation, and purification, from the total production of cassava as much as 203,417 tons / year, 25,683 kg / hour of cassava will be used with 1093.4 L / day of bioethanol. The 100% power potential without a gasoline mixture is 266.75 kW, while 10% ethanol with a mixture of 90% gasoline is 402.79 kW.
