Abstract
Abstract- Methanol and co-solvent after being separated from the rest of the methyl ester had only discarded, but if reused will save the reactant and the co-solvent used. Variables of research is the reaction time is 3, 8, 13, 18, 23, 28 and 33 minutes and the mass addition of methanol and co-solvent residual is 0, 5 and 10% by weight. Papaya seeds that have been dried and pulverized size + 20/-30 mesh around 100 grams introduced in to the reactor and added methanol, THF and the catalyst NaOH and the reaction carried out according to the study variables and operating conditions. After the reaction was complete, added HCl 1 mol /L to pH 4 to stop the reaction and separated between cake and the filtrate. The filtrate was distilled at 70°C until no distillate dripping. Distillate was a mixture of methanol and co-solvent the rest of reaction to be used again in the reaction. Distillation residues incorporated into separating funnel and allowed to stand for 12 hours in order to form two layers. The bottom layer was glycerol and the upper layer as the methyl ester. Methyl ester concentration was analyzed by GC. The optimum conditions of the research on the mass addition of methanol and co-solvent remaining 10% and a reaction time of 8 minutes, methyl ester concentration of 99.39%, yield of 79.51%, density of 0.87 g/cm3 , and acid value of 0.74 mg KOH/g. These results regards with SNI 04-7182-2006. Keywords Methanol, co-solvent, reused, papaya seeds, methyl ester.
