Pengembangan Proses Enzimatis Untuk Produksi Biodisel Dari Minyak Jarak Pagar dan Uji Performa Pada Mesin Disel
Abstract: oil reserved that
belonged to Indonesia is limited. In order that there were some efforts have
performed to seek an alternative gr.rn una renewable fuel such as biodiesel.
Biodiesel production from Jatropha curcas is basically methanolysis reaction,
the reaction of triglyceride with metLanol yield to methyl ester and glycerol.
This transesterification is performed enzimatically because it has some
advantages: energy save, complete transesterification for high free fatty acid
and water easy drawn for glycerol, and no washing.
The objectives of this research is ti develop enzymatic process to
produce biodiesel from Jatropha curcas by using indigeneous enzyme from papain
lateks and husk. The achievements are date for design' scale-up and process
condition including kinetics reaction, optimum process and data of engine
performance. In first year, designing and fabricating. of enxymatic reactor was
done followed by studied of kinetics reaction and process computing. Model
building was performed based on Michaelis-Menten theory. Model was postulated
and then broken down to empirical equation that will be examined and validated
by experimental data gathered. The result in the first year showed that longer
in time more biodiesel got in conversion at alter ratio. Lipase activity
increased in increasing temperature. The optimum temperature was 51°C. Adding
n-hexane solvent has been able to increase conversion in transesterification
reaction and to increase enzymatic reaction rate.
