Abstract :
The utilisation of bioenergy has proved to be an effective solution to reduce the
consumption of fossil fuels. One instance of the use of such bioenergy is
bioethanol, which is also known as ethanol or ethyl alcohol. Having the chemical
formula of C2H5OH, ethanol is essentially an organic compound with a
noteworthy superiority in comparison with ordinary gasoline, i.e., it is capable of
reducing the amount of CO2emission up to 18%. Bioethanol is resulted from a
series of processes, one of which is the hydrolysis, where the presence of an
element called the catalyst is pivotal to expedite the chemical reaction. Using the
amylase enzyme extracted from the sprout of mung beans as its catalyst, this
research aims to establish the best time of the chemical reaction resulted from the
use of the concerning catalyst, the amount of the enzyme being the most suitable
for process of hydrolysis, as well as the efficacy of the use of the enzyme in the
hydrolysis. In the process of hydrolysis, besides amylase enzyme, glucoamylase
enzyme is another element of necessity. The research draws upon the Brix
analysis, reducing sugar, total sugar, and Dextrose Equivalent (DE) as
parameters. As for the means of data analysis, the researcher opts for the socalled
Completely Randomised Design (CRD). The result of the research reveals
that amylase enzyme has the capacity to work as a catalyst in the hydrolysis
process as it establishes Brix point of 12, reducing sugar of 8.51%, 16.91% of
total sugar, and 50 DE point. These numbers also indicate the production of
glucose syrup from the hydrolysis.
Keywords: Amylase enzyme, hydrolysis time, mung bean sprouts.
