Biodiesel, a renewable fuel derived from vegetable oils, has gained attention as a sustainable alternative to fossil fuels. The study's goals are to find the best conditions for making biodiesel from corn oil using the transesterification method and to look at how different molar ratios and catalyst types affect the quality and yield of biodiesel. This study conducted the transesterification process using methanol, NaOH, and CaO as catalysts. The molar ratios of oil to methanol were 1:12, 1:15, and 1:18. The study conducted the reaction at 60°C for 120 minutes. The characteristics of the produced biodiesel were density, kinematic viscosity, and methyl ester content, and we compared the results to biodiesel quality standards. This study found that a molar ratio of 1:12 with CaO as a catalyst resulted in optimal biodiesel properties, including a density of 862.87±2.01 kg/m³, a viscosity of 2.77±0.12 cSt, and a methyl ester content of 96.85±0.91%. These results show that the molar ratio and type of catalyst have a big impact on the production of biodiesel. CaO worked better than NaOH at meeting quality standards.References
