PRODUKSI BIOETANOL DARI JERAMI PADI DENGAN METODE SIMULTANEOUS SACCHARIFICATION FERMENTATION (SSF)
Abstract: Production of
bioethanol from rice
straw has been
carried out. Rice
straw was used
as main material for
bioethanol production. Pretreatment
firstly has been
done to release
cellulose from lignin. By using
mixture of NaOH 2% and NH4OH with varied concentration from 2% to 10%. Ratio of
rice straw :
mixture of NaOH-NH4OH
in pretreatment varied
ratio 1:10, 1:15,
1:20. Optimum pretreatment resulted
in NaOH 2%
and NH4OH 6%
with ratio of
rice straw and mixture of NaOH-NH4OH 1:15. Result of
rice straw saccharification by using extract of cellulose enzyme from
Trichoderma viride strain
T1 Sk against
pure substrat CMC
showed enzyme activityas 0.015
unit. Saccharification also has been done against amount of rice straw
substrate from 0.1 g
to 1 g and saccarification time
from 30 to
105 minutes. Maximum
concentration of glucose was
182,9 µg/L given by 0,6 g rice straw substrate with optimum saccharification
for 60 minutes. Ethanol produced
as 2,0151 mL
from 3 mL
Volume produced for
144 hours fermentation time
