Pemanfaatan Ampas Sagu Untuk Produksi Bioetanol Dengan Variasi Nisbah Ampas Sagu-Pelarut Dan Waktu Pretreatment

ABSTRACT
Sago waste is a lignocellulosic material that can be used as a raw material for
making bioethanol. The lignin content in lignocellulose can inhibit the rate of
saccharification by blocking access to cellulase enzymes in cellulose. The
pretreatment stage is the initial stage of the conversion process of lignocellulose to
bioethanol with the aim of reducing lignin levels in lignocellulose. The next steps
in the conversion of lignocellulosic material to bioethanol are saccharification and
fermentation. In this study, the pretreatment stage was carried out using 10% NaOH
solution at a 4 bar pressure reactor and a temperature of 140 oC, while the
saccharification and fermentation stages were carried out simultaneously (SSF)
with the help of cellulase enzymes and yeast Saccharomyces cerevisiae at
temperature conditions of 30 oC and pH 5. The research was carried out by varying
the ratio of sago waste with NaOH solution and the time of the pretreatment process.
The ratio of sago waste and the solvent used were 1:5, 1:6, and 1:7, while the
processing time started from 20 minutes, 30 minutes and 40 minutes. The highest
lignin reduction results were obtained at a ratio of 1:7 and a pretreatment time of
40 minutes, which was 60,11%, the highest yield of sago pulp mass was obtained
at a ratio of 1:5 and a pretreatment process time of 20 minutes which was 35,14%.
The results of the initial treatment stage were then continued with SSF for 0 hours,
24 hours, 48 hours, and 72 hours with the highest bioethanol content of 12% at 72
hours.
