Abstract

Biodiesel is an alternative fuel to diesel, produced from vegetable or animal oils through esterification–transesterification using a mobile lipase enzyme catalyst in a Packed Bed Reactor. In this study, varying amounts of enzyme 11.25 g, 13.75 g, 16.25 g, 18.75 g, and 21.2 g were applied at two reaction times 4 and 5 hours. The highest yield 90.06% was achieved at 5 hours with 16.25 g enzyme, resulting in a cetane number of 64.96, FAME content of 97.22%, and flash point of 112.7°C. The lowest yield (86.76%) occurred at 4 hours with 11.25 g enzyme, with a cetane number of 62.31, FAME 96.86%, and flash point 95.7°C. The results show that both enzyme amount and reaction time significantly affect biodiesel yield. A longer reaction duration enhances the conversion of triglycerides into methyl esters. All biodiesel quality parameters were analyzed according to the Indonesian National Standard (SNI) 7182:2015.
