ABSTRACT
Bioethanol is one of the alternative energy substitutes for petroleum. the wasted of
sago can be used for bioethanol production. The main component of sago is used
for the production of bioethanol is lignocellulose which consist of cellulose,
hemicellulose and lignin. Ethanol is made by hydrolisiys and fermentation with
the help of an acid catalyst and saccharomyces cerevisiae. This study aims to
exploit the potential contained in sago waste as a producer of bioethanol by using
the hydrolysis process method acid and time of the hydrolysis process, knowing
the amount of sugar content resulting from the acid hydrolysis process and the
time of the hydrolysis process, Knowing the ethanol content formed from the time
variation in the fermentation process. The variables used are sulfuric acid
concentration, hydrolysis time and also the time when fermentation. this research
starts with the pre treatment of sago pulp, then hidrolysis with, with variation 1n,
2n, 3n in 145 degree during 20 minutes, 30 minutes, minutes, 40 minutes and 50
minutes. Then the results of hydrolysis fermented using sacchaomces cerevisiae.
The fermentation process lasted for 24 hours, 48 hours 72 hours, 96 hours, and
120 hours. The results showed that the largest sugar concentration was obtained
during concentration of H2SO4 3 N with time 50 minutes amounting to 25,08 g/L
the greatest bioethanol content and levels are obtained from the fermentation
during 96 hours is 4,751 g/L or 15 %.
Keywords : bioethanol, fermentation, hydrolisis, sago pulp, pre-treatment
