DETOKSIFIKASI HIDROLISAT ASAM DARI UBI KAYU UNTUK PRODUKSI BIOETANOL
ABSTRACT: The production of
bioetanol by using acid hydrolisis method resulted the formation of compounds
which can destructed the fermentation process, such as HMF or furfural, thus it
needs detoxification process to erase or decrease it. Detoxification process is
done by adding alkali in to hidrolisat before it is used as fermentation
substrat. Alkali compound which is usually used are Ca(OH)2 or NH4OH. This
research is conducted to compare ethanol rendement resulted from the
detoxification process, and also to decide the most optimal detoxification that
can be done to produce the best etanol rendement. The study is done by using
distinct treatmentof catalist, that are Ca(OH)2 dan NH4OH as well as the
stirring/mixing time, which are control, 15, 30 and 45 minutes during
detoxification process. Based on the result of the study, it can be concluded
that etanol rendement resulted from hydrolisat which is detoxificated by using
catalyst NH4OH is higher than the one which use catalyst Ca(OH)2. Acid
hydrolisat detoxification method from cassava in order to produce an optimal
bioetanol is by using catalist NH4OH with free stirring time(less than 15
minutes)
