Potensi Katalis AlCl3 terhadap Produksi Biodiesel dari Lipid Fitoplankton Porphyridium cruentum

A research on the potential of AlCl3 catalyst from lipid of phytoplanton Porhyridium cruentum. In this research, we carried out o series of phytoplankton culture. Process of biodiesel synthesis consists of two steps, i.e isolation of phytoplankton lipids and biodiesel sunthesis from that lipids. Oil isolation process was carried out by ultrasonic extraction method using ethanol 96 % while biodiesel synthesis was carried out by transesterification reaction using methanol and AlCl3 catalyst under sonication. Lipid of phytoplankton Porphyridium cruentum obtained is 16,2667 %. Lipid obtained has FFA content > 5 % and water content < 0,5 %. Characterization of biodiesel was carried out : water content, FFA content, saponification value, and density. The result of characterization of saponification value and density fullfilled the American Society for Testing and Materials (ASTM D6751) standard
