The characterization result of the catalyst using X-Ray of wide-angle powder (WAXRD) and Scanning Electron Microscope (SEM) gives information that the existence of silica as support of SO/TiO active site. Observation data were analyzed by Response Surface Design (Composite Central Design). The results of the conversion design analysis, it was observed that the number of catalysts: 5%, Ethanol / PFAD molar ratio: 13 and reaction time: 2.25 hours as a variable for optimization of the esterification process The physical characterization of ethyl ester as biodiesel is recorded by viscosity and density according to ASTM D-6751. The presence of functional groups which show the formation of ethyl esters indicated by FTIR analysis as C-H (alkanes), C=O, C-O and C-H (alkyl, R). The composition and type of ethyl ester from fatty acids were determined through GC-MS analysis. The highest peaks are indicated as palmitate ethyl ester, stearate ethyl ester and oleate ethyl ester and inform that the esterification reaction carried out has succeeded in producing highquality biodiesel ## Keywords - Biodiesel - Fatty acid - Catalysis - Chemistry - Organic chemistry - Mesoporous material - Lipase - Mesoporous silica - Ethyl ester - Fatty acid ester - Fatty acid methyl ester - Enzyme --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
