PENGOMPOSAN SERABUT BUAH KELAPA SAWIT MENGGUNAKAN Aspergillus terreus SUK-1 DAN EM4
ABSTRACT: Composting is
a natural microbial
process involving organic
residues. At the
end of this process, the low-value organic residues
are consequently converted into higher-value products. It has become
more widely accepted
among those interested
in organic farming,
since the process is also
considered as a practical alternative for use in the management of organic
residues. However, the use of
compost as organic
fertilisers is invariably
associated with the
constraint in their
production. The Aspergillus terreus
SUK-1 is known
to produce large
amounts of enzyme
ß-glucosidase, and thus could be effective for the degradation
of cellulose. EM4 is an inoculant comprising 90% of the bacteria involved in
fermentation and in
lactic acid production.
In this study,
Aspergillus terreus SUK-1
and EM4, together with chicken dung as control, were used to determine
and compare their effects on the composting
of oil palm
fruit fibres. The
experiment design was
randomized completed design
with three treatments, namely
Control (with chicken
manure), Aspergillus terreus
SUK-1 and EM4.
Each treatment is replicated
five times. The
parameter observed was
temperature, pH, humidity,
carbon contents, nitrogen contents and
C/N ratio. the
result of this
study showed that
EM4 is more
than effective compare to another for composting of oil palm fruit
fibres. The pH, carbon contents,
nitrogen contents and C/N ratio values of EM4 treatment at the end of composting
were 7.53, 20.54, 2.94, 7.02, respectivel
and EM4 give
ideal temprature for
compos process campare
to Aspergillus terreus
and control. Based on
analyses of variance,
EM4 showed significant
differences with Aspergillus
in temperature, nitrogen and carbon contents, while control in all
parameters. for commercially purpose, EM4 is more recommended to use in
composting of oil palm fruit fibres because of it is cheaper, easy to obtain in
the market and high quality of composting.
