| Summary: | . This paper presents an optimization of bioethanol production
from oil palm trunk sap (OPTS) fermentation. The OPTS was obtained from
an old palm tree (30 years old), whereas ethanol fermentation was carried
out using Saccharomyces cerevisiae. The sugar content in OPTS and
fermentation mother liquor was determined using high-performance liquid
chromatography (HPLC). The parameters such as initial pH, temperature,
and agitation rate were optimised using response surface methodology
(RSM) with rotatable central composite design (CCD). It was found that the
highest yield of bioethanol (75.82%) was obtained at the initial pH (5.79),
temperature (31.05 ºC), and agitation rate (164.38 rpm). The optimization
model of OPTS fermentation to bioethanol developed in this work may
provide useful guidance to obtain a high ethanol yield from OPTS. |
