Abstract

Sunan Hazelnut is one plant that thrives in Indonesia and have high productivity is 50-300 kg per tree per
year, with oil content of 45-55%, so it very potential to be used as raw material for biodiesel production.
Sunan Hazelnut oil can not be converted directly into biodiesel because the free fatty acid (FFA) content is
high. To overcome this problem, a two-stage process can be conducted. The first stage aims to reduce the
content of FFA in oils through esterification reaction using an acid catalyst, the second stage is the
production of biodiesel through transesterification using alkaline catalyst. In this study, the esterification
reaction is carried out in certain condition. The variables being studied is the effect of the concentration of
NaOH catalyst and time of the transesterification reaction. The results shows that the FFA content can be
reduced to 0.55% using sulfuric acid catalyst 0.5% by weight of oil, oil to methanol ratio of 1:5 and a
reaction time of 120 minutes. Then, oil is converted into biodiesel using NaOH catalyst, obtained a
conversion of 83% on the amount of catalyst 0.75% by weight of oil, methanol to oil ratio of 1:7 and a
reaction time of 90 minutes. Biodiesel produced has a density of 875 kg /m3
, 2.35 cst of viscosity, flash point
of 163oC and pour point of -2,5oC.
