| dc.description.abstract | MERRY CRISTIN NATALIA SIMAREMARE: The Effect of Acrylic Coating
on Oil Palm Trunk Waste Particle Board. Under academic supervision by TITO
SUCIPTO and LUTHFI HAKIM.
To reduce the waste of oil palm trunks can be done by changing oil palm trunks
into particle board. One way to improve the quality of particle board is by doing
coating treatment of acrylic. This study evaluated the best acrylic level in
improving the quality of oil palm trunk particle board with isocyanate as the
adhesive. Boards were made with size 25 cm x 25 cm x 1 cm with a target density
of 0.7 g/cm3, felts temperature 160º and pressure 25 kg/cm2 for 3 minutes.
Physical and mechanical properties were compared with SNI 03-2105-2006. The
treatment variations were acrylic levels (0%, 5%, 10%, and 15%) with 3
repetitions. Results showed that the values of the density, moisture content, water
absorption, thickness swelling, modulus of rupture, modulus of elasticity and
internal bond were respectively 0,46-0,60 g/cm3, 10,52-11,01%, 5,32-55.35%,
2,37-6,40%, 26,45-60,87 kg/cm2, 2619,15-5092,82 kg/cm2 and 2,28-4,61 kg/cm2.
All result values of physical properties testing except value of the moisture content
achieved the standards of SNI 03-2105-2006. Instead, all result values of
mechanical properties testing did not achieve the standards of SNI 03-2105-2006.
The results showed that the particle boards with acrylic coating treatment has
better quality than the particle boards without the acrylic coating treatment for
the entire physical properties testing in addition to moisture content. Best acrylic
level for the coating treatment of oil palm trunk particle board is 15%. | en_US |
