Pengaruh Konsentrasi Asam Klorida (Hcl) Pada Proses Hidrolisis Dan Waktu Fermentasi Terhadap Limbah Padat Sagu Menjadi Bioetanol

ABSTRACT
Bioethanol is a bioenergy that can be used as an alternative fuel. One of the raw
materials that can be utilized is sago solid waste. Sago pulp biomass, which is a
lignocellulose material, contains considerable potential as a basis for bioethanol
based on the availability of certain components (starch and cellulose) it contains.
Cellulose content found in sago solid waste can be converted into bioethanol
through hydrolysis and fermentation processes. This study aims to synthesize
bioethanol from sago solid waste, determine the effect of HCl concentrations on
the hydrolysis process and determine the optimum time of bioethanol production
from sago pulp waste by the method of separate hydrolysis and fermentation
(SHF). The research began with pretreatment of sago pulp using 1M NaOH, then
the hydrolysis process used HCl with a variation of 1 M, 2 M and 3 M at 100oC
for 3 hours. Then the hydrolysis results are fermented using Saccharomyces
cerevisiae. The fermentation process lasts for 24 hours, 48 hours, 72 hours, 96
hours and 120 hours. The results showed that the largest sugar concentration
obtained at the 2 M HCl hydrolysis was 140.18 gr / L and the best bioethanol
content was obtained from fermentation for 96 hours is 7% or 55.25 gr / L.
