Pengaruh Konsentrasi H2so4 (Asam Sulfat) Pada Proses Hidrolisis Dan Waktu Fermentasi Terhadap Pemanfaatan Limbah Sagu Menjadi Bioetanol

---

ABSTRACT
Bioethanol is a renewable alternative energy source that can be used as an
alternative fuel. Bioethanol is a fermented product that can be made from
substrates that contain carbohydrates (sugar, starch, cellulose). Sago pulp is a
very abundant biomass that has not been utilized properly, so far sago pulp has
only been used as fertilizer and animal feed. Biomass containing cellulose such as
sago pulp can be converted into bioethanol through hydrolysis and fermentation
processes. The purpose of this study is to examine the use of sago pulp as a raw
material in the manufacture of bioethanol, determine the effect of sulfuric acid
concentration on the hydrolysis process and determine the optimum time of
bioethanol production by the method of separate hydrolysis and fermentation
(SHF). The steps taken in this research were pretreatment of sago pulp using
NaOH 1M. Acid hydrolysis using H2SO4 with variations in concentrations of 1 M,
2 M and 3 M at 100oC with a reaction time of 3 hours. The fermentation process
uses Saccharomyces cerevisiae with a variation of fermentation time of 1 day, 2
days, 3 days, 4 days and 5 days. The results showed the highest sugar content was
found in the hydrolysis process of sago pulp with the addition of 2M sulfuric acid
concentration which was 134.08 g / L. The highest levels of bioethanol in the SHF
process were also obtained at 4 days fermentation for 8% or 63.14 g / L.
