摘要

__________________________________________________________________________________________ In this research new feedstock biodiesel was produced from Crude Reutealis Trisperma-Oil (RETRO). RETRO is vegetable oil that is overabundance in Indonesia it has not been explored because of its toxicity. RETRO was prepared through the reaction of esterification with methanol by using sulfuric acid catalyst to decrease Free Fatty Acid (FFA), and then transesterification reaction of refined RETRO was performed with methanol by using the alkaline catalyst. RETRO transesterification reaction using potassium hidroxyde (KOH) as catalyst with variation of 0.5 – 2,0 wt% of oil has been done at 65 °C. The biodiesel yield increased with the catalyst concentration increasing of 0,5-1,0 wt% and decreased when the catalys concentration of 1,5-2,0 wt%. The optimum yield of fatty acid methyl ester (FAME) was 83,33 %, it was obtained with various KOH catalyst at the oil catalyst concentration of 1,0 wt% . The characterization of RETRO biodiesel was done by comparing it with ASTM D6751-02 method, and it got the acid number of 0,55 mgKOH/g, density of 0,90 g/cm3, viscosity of 10,63 cSt at 40 °C, cetane number of 54,7 and carbon residue of 0,24%.
