PEMBUATAN BIOETANOL DARI MINUMAN SERBUK AFKIR
ABSTRACT: Bioethanol can be
made from three kinds of materials which contains glucose, starch, and cellulose.
The creation of bioethanol from glucose substance considered the easiest
becauseonly needs two-stage process, fermentation and distillation. Nowadays,
the creation of bioethanol from glucose and starch creates new problem due to
the demand of the glucose and starch for food needs. Therefore, the non-food
sources bioethanol should be found. One of them is from expired date powder
beverage. The purpose of the research is to compare the bioethanol creation
process using two kinds of distillation equipment. The analysis consist of
yield and the purity of the bioethanol. Fermentation is carried out for 14 days
using a 0.5% Fermipan yeast, Urea and TSP fertilizers. One time distillation
using equipment with controlled temperature about 78oC for 6 hours produced
bioethanol yield 20% and 95% purity. The simpler distillation tools without
temperature controls, due 21.5% bioethanol, with 80% purity in twice
distillation process. It can be concluded that controlled temperature at the
ethanol's boiling point during the distillation process, produces higher yield
and purity of the bioethanol also faster processing time. If the distillation
temperature is too high, there will be lots of evaporatedbioethanol to the
ambient and water will evaporated and condensed, so the ethanol purity willbe
lesser.
