dc.description.abstractBiodiesel is an alternative energy that is intended as a fuel for diesel engines. Biodiesel is produced through a transesterification reaction in the presence of a catalyst. This research was carried out by synthesizing biodiesel with CaO catalyst from blood clam shells modified with SiO2 from palm shell fly ash through impregnation method. SiO2 1% impregnated with CaO. The surface area of 1% CaO-SiO2 catalyst analyzed by BET test was 7.1298 m2g-1. The functional groups obtained are O-H from Ca(OH)2, stretching vibration asymmetry Si-O-Si and groups Ca-O. The maximum biodiesel yield obtained on a 1% CaO-SiO2 catalyst was 80.77% at a reaction time of 90 minutes, a catalyst weight of 2 g and a mole ratio of oil: methanol 1:9. The characterization of water content, specific gravity and viscosity complies with SNI 04-7182-2015, except for acid number and carbon residue.en_US
