- Transesterification is the reaction to produce methyl esters in which this reaction’s involves catalyst of blood clam shell ashes of combustion at temperatures of 900 ° C for 3 hours and the amount of ash that is used by 8%, 10%, 12% (w / w). Ash used in dissolved in methanol with a molar ratio of methanol: oil of 9: 1, 12: 1 (n / n) to obtain a compound of calcium methoxide. Used cooking oil is filtered and then esterified with catalyst 3.0% (w / w) H2SO4 98% and methanol: oil TG (6: 1) to reduce the FFA to <1%. Transesterification reaction is carried out at a reaction temperature of 65 ° C for 3 hours, and keep stirring 700 rpm. Quantitatively, the optimum yield of methyl ester in the amount of ash produced is 12% (w / w) and the molar ratio of methanol: oil at 12: 1 (n / n) of 56.51% with specification methyl esters such as density, kinematic viscosity and purity methyl ester biodiesel in accordance with SNI 04-7182-2006, based on the analysis of GC (Gas Chromatography), the purity of the resulting methyl ester was 98.79%.
