OPTIMASI PRODUKSI BIOETANOL DARI LIMBAH PABRIK GULA (MOLASE) DENGAN MEMVARIASIKAN BRIX DAN KONSENTRASI RAGI

When 2020 began the outbreak of new pneumonia,
namely the coronavirus disease 2019 (COVID-19),
alcohol suddenly became less available because it was
the most sought-after item. This is because 70% alcohol
can be used as an antiseptic and disinfectant solution
that can overcome the transmission of the coronavirus
(Covid-19). The manufacture of 70% alcohol can use
alternative materials from sugar industry waste, namely
molasses. The purpose of this study was to determine
the effect of variations in Brix and yeast concentration on
the level and volume of alcohol made from molasses and
how much Brix and yeast concentration to obtain optimal
bioethanol yield. The research method used is the
experimental method. The variations of Brix used were
12%, 15%, and 18%, while the yeast concentrations
used were 0.5%, 1%, and 1.5% of the total sample
weight. Bioethanol production is carried out by
fermentation process for 48 hours against 30 kg of
molasses solution, but firstly, the propagation process is
carried out for 2 hours. Then it is distilled to get
bioethanol from the fermentation of molasses. The
results of this study indicate that the two various factors
affect the volume and level of bioethanol produced, but
the variation factor Brix is the dominant factor in
determining the volume and alcohol content. The optimal
treatment to produce the highest volume and content of
bioethanol is Brix 15% and yeast concentration of 1%
with an average volume of bioethanol produced as much
as 1882 ml and the resulting alcohol content of 84%
