Production of Biodiesel from used cooking oil is usually carried out in three stages of the process, namely the purification of used cooking oil, esterification, and transesterification.However, esterification requires a lot of methanol, making it less economical. Esterification can be replaced by the adsorption.Adsorption was carried out to eliminate FFA content of used cooking oil by using activated natural bentonite adsorbent. This study consists of two main stages, namely purification and conversion. Purification consist of despicing, neutralization, and bleaching (adsorption). In this study, adsorption was carried out at the temperature variation of 30,40,50,60,70,80,90 °C to observe FFA and water content. The treated used cooking oil with lowest FFA content was then converted into biodiesel. The obtained biodiesel was analyzed its flash point, viscosity, and density. The best adsorption results occurred at adsorption temperature of 30 and 50oC with the reduction of FFA by 0.2176% and 0.192%, while it was 0.05% for the water content. As for the flash point, viscosity, and density of the obtained biodiesel is already meet the standards of biodiesel, which is 170 oC, 5.021 mm2/s, and 0.8702 kg/lt (adsorption temperature of 30 oC) and 170 oC, 5,119 mm2/s, and 0,8711 kg/lt (temperatur adsorpsi 50 oC). Keywords :Biodiesel, Bentonite, used Cooking Oil, Adsorption
