Abstract: The utilization of rice husk as raw material on
preparation of composite board could be used as alternative and
cheap construction material.
In this research,
the composite board
was prepared by mixing
fined rice husk,
recycledhigh density polyethylene
(HDPE) plastic. Maleic Anhydride (MAH)
was added ascompatibilizer. The objective
of this research is to develop
an alternative and a
cheap technologyon fabrication
of composite board
by utilizing rice
husk waste as filler and plastic from the type of recycled HDPE plastic
as matrix. In order to improve the
compactness of rice
husk and recycled
HDPE plastic thus
the addition of
MAH as compatibilizer is
carried out. The
research aspect learned
is the MAH
addition variation as much of 4% and 8% from HDPE plastic
weight, and the mixing ratios of filler and matrix which are 30:70;
40:60; 50:50; 60:40;
70:30. Casting process
of the homogonized
solution was carried
out at casting
temperature of 145oC
for 20 minutes.
The research result
obtained indicates that the
value of composite
board density has
fulfilled standard of
SNI 03-2105-1996. The maximum
water adsorbtion is obtained on composition of filler and matrixof 60:40 where with
the addition of MAH 4%
and 8% they
are 10,1% and
6.9%, respectively. The addition
of MAH as
much of4% and
8% has resulted
composite board with
tensile strength value that
has fulfilled SNI
standard. Whereas the
addition of MAH
as much of
8% could increase modulus of rapture
value of composite board i. e. 82.5 – 85.2 kgf/cm2and they have fulfilled
standard of SNI 03-2105-1996.
