Proses Transesterifikasi Biji Minyak Jarak Dengan Bantuan Enzim Lipase Sebagai Penghasil Biodiesel
Abstract: The investigation
was carried out to prevent the scarce of fosil based fuel. In this
investigation used seed of castor oil plan (Jathropha curcas L.) as natural row
material to make castor oils and converted to biodiesel so that it’s friendly
to the biological environment. Castor oils produced by extraction process with
soxhletation methods used n-hexane solvent. The result of extraction then
converted to biodiesel by transesterification process at optimum temperature
40o C with methanol and catalyzed with lipase enzyme. Free fatty acid analysis
and total fat analysis was done to the result product, and then biodiesel
converted value as 88.67% gotten. Some characteristics analysis of biodiesel
castor oils like density, viscosity, pouring point, flaming point, and caloric
value according ASTM D6751. The result of investigation showed castor oils
biodiesel can be used as diesel fuel.
