Abstract: The need of
wood as one
of raw materials
in furniture industry
keeps increasing. One of
efforts to reduce wood consumption is to develop research by creating composite
design from material that contains
sellulose to be
particle board. Particle
board is one
of material alternatives that
can be wood substitute.
The objective of this
research is to investigate the effect of natural-adhesive-mixture
composition (acacia bark and gambier) with oil-palm-empty bunch toward
mechanical property of
particle board. Characterization of
particle board was carried
out by undertaking
mechanical property testing
(tensile strength and
compressive strength) under wet
and dry conditions.
Composition variations of
adhesive and oil-palm-empty bunch
were 30:70; 40:60;
50:50; 60:40; 70:30.
Making process of
particle board is carried
out by mixing
oil-palm-empty bunch and
adhesive with addition
of 2% para-formaldehyde and water as much of 10%.
Furthermore, the mixture is compressed by using Hot Press
at temperature of
150oC and pressure
of 10 kg/cm2
for 15 minutes. The
research result indicates that the higher the adhesive composition
(either adhesives of acacia bark or gambier), particle board resulted is
better. In dry condition, values of the
tensile strength of particle boards that
have acacia bark adhesive and
gambier adhesive have
range of 84.2 -
104 Kgf/cm2 and 83.4 - 81.5 kg/cm2, respectively. Whereas, values of
compressive strength of particle boards
that have adhesives
of acacia bark and
gambier are in the
range of 6.8 - 10.5 kg/cm2 and
6.3 - 9.3
kg/cm2, respectively. The
values of tensile
strength and compressive strength
are obtained on
compositions of adhesive:
oil-palm-empty bunch ≥ 40:60, and they have fulfilled satandard of
SNI 03-2105-1996. The values of tensile strength and compressive strength of
particle board in wet condition, either adhesives of acacia bark or gambier,
have not fulfilled standard of SNI 03-2105-1996.
Keywords: empty-bunch-oil palm, acacia bark, gambier, particle board,
