Pembuatan dan Uji Coba Alat Pengolahan Minyak Jelantah Menjadi Biodiesel Skala Pilot Plan

Abstract

Used cooking oil is a waste product from frying that can be processed into biodiesel as an alternative renewable fuel. This study aims to design, fabricate, and test a device for converting used cooking oil into biodiesel using esterification and transesterification processes. The developed system consists of a raw material tank, main reactor, separation tank, and washing tank. Experiments were conducted with varying methanol-to-oil ratios and catalyst types to determine the optimal parameters for biodiesel production. The results show that esterification and transesterification processes successfully reduced the free fatty acid content in used cooking oil, producing biodiesel that meets the SNI 7182:2015 standard. However, the efficiency of the device needs further improvement, particularly in temperature control and reactant mixing, to enhance reaction optimization.
