dc.description.abstractThis research aims to synthesize biodiesel using a CaO catalyst from blood cockle shells impregnated with SiO2 from coconut fiber at a concentration of 3% w/w. The resulting catalyst was characterized using the Brunauer Emmett Teller (BET) method showing that the surface area of the 3% CaO-SiO2 catalyst had a higher area compared to CaO without modification. Scanning electron microscopy-energy dispersive x-ray spectroscopy (SEMEDX) had a rough surface morphology. and agglomerate and the main elemental composition of the 3% CaO-SiO2 catalyst is Ca, Si and O, and the basicity test of the 3% CaO-SiO2 catalyst has lower basicity compared to CaO. Biodiesel production is carried out by varying catalyst weight, temperature and reaction time with optimization using the Response Surace Methodology (RSM) design. Characterization of biodiesel produced from a 3% CaO-SiO2 catalyst has water content, specific gravity, viscosity and carbon residue which generally meets the quality requirements of SNI 7182-2015, except for the acid number.en_US
