PREPARASI BIODIESEL DARI MINYAK JELANTAH KELAPA SAWIT

Abstract

Synthesis of biodiesel from used cooking oil was carried out in two step reactions i.e esterification and
transesterification. The biodiesel obtained was analysed using gas chromatography and mass spectrometer (GC-MS).
The quality was determined by comparing its physico chemical properties and compared to the Jerman Standard DIN
V 51606.
The result of GC-MS showed 6 peaks coresponding to six methyl ester(biodiesel): methyl myristate, methyl
palmitate, methyl linoleate, methyl oleate, methyl stearat and methyl arachydate. The biodiesel obtained has a density
of (0,8976±0,0003 g/mL), viscosity of (4,53±0,0872 mm/s), acid value of (0,4238±0,0397 mg KOH/g, and iod
number of (9,3354±0,0288 g iod/100 g sample). There properties were in a good agreement with the standard Jerman
DIN 51606.
