ABSTRACT: A number of microbes
are known to have ability to degrade synthetic polymers such as polyeugenol.
This research was attempted to know the genus of bacterium that isolated from
Gunung Tugel garbage dumping land which is able to degrade polyeugenol and to
characterize polyeugenol before and after biodegradation process using this
bacterium. Pure eugenol was polymerized into polyeugenol by adding concentrated
sulphate acid, and then formed become a thin film. Bacterium which is isolated
from Gunung Tugel garbage dumping land was suggested as Acinetobacter sp.
Polyeugenol thin film was incubated with this bacterium with various incubation
times 5, 10, 15, 20, 25, 30 and 60 days. Thin film then was characterized
including melting point value, percentage of weight loss, molecular weight, and
the function groups by FTIR. Melting point of initial polyeugenol was 135-137oC
and after biodegradation was 98-100oC. Percentage average of loss weight was
0.5637% (b/v). Molecular weight of polyeugenol before degradation was
61.472.882,91 g/mole and after biodegradation was 5,542,915.464 g/mole. FTIR
spectrum percentage of transmittance of polyeugenol after biodegradation was
decreased.
