Abstract
According to the Central Statistics Agency (BPS), Indonesia's oil reserves in 2020 will reach 4.17 billion barrels. Meanwhile, according to the SKK Migas project, oil demand will continue to grow from 82.8 million tons of petroleum equivalent (MTOE) to 112.9 MTOE in 2030, to 197.7 MTOE or the equivalent of
3.97 million barrels of oil per day in 2050. Therefore, it is necessary to develop alternative fuels that are renewable, more environmentally friendly, and affordable by the community. This research was conducted to process used cooking oil into biodiesel with different catalysts and influenced by different characteristics. The transesterification process reacted 250 ml of used cooking oil with 50 ml of methanol and NaOH and KOH. In the disposal process, the above solution is allowed to stand for 1 day after which it is deposited, and the solution will produce a barrier between the oil and the removed glycerol. The washing process is carried out by mixing the oil into water at a temperature of 50-60 0C for 20-30 minutes and after that discard the washing results. The characteristics of the 4 biodiesel that have been studied are only 3 out of 4 that have met the characteristics according to the SNI Quality Standards, namely the flash point, density, and water content.
