PENGARUH WAKTU ESTERIFIKASI TERHADAP PROSES PEMBENTUKAN METIL ESTER (BIODIESEL) DARI MINYAK BIJI KARET (RUBBER SEED OIL)
Abstract: Biodiesel from rubber seed oil (Hevea brasilliensis)
can be produced through two step processes, esterification and
transesterification, and the objectives of this research are to know the effect
of esterification reaction time on producing metal ester (biodiesel) from
rubber seed oil. The method of this research is started by preparation process,
including pressing and extraction of the rubber seed oil. The next step is
esterification with acid catalyst (H2SO4) 3 % volume from rubber seed oil used,
reactants are rubber seed oil and excess methanol with ratio 1:2 at 60-65oC for
1 hour, 2 hour and 3 hour. The processes are continued with transesterification
prosess with base catalyst (KOH) 2 % weight from rubber seed oil used,
reactants are rubber seed oil and excess methanol with ratio 1:2 at60-65oC for
2 hour. The last step of this processes are yield and quality of biodiesel
analysis. The results of this research shows that the maximum conversion
biodiesel yield of 95% can be obtained at 3 hour of esterification reaction
time.
