Variasi Suhu dan Waktu Pengempaan terhadap Sifat Fisis, Mekanis dan Ketahanan Rayap Partikel dari Limbah Batang Kelapa Sawit dengan Perekat Phenol Formaldehida

Abstract

SYAHRONI HASAN SIREGAR: The variation of Temperature and Time Pressing of Physical, Mechanical and Toleration Termite Properties Particle Board from Waste Oil Palm Trunk with Phenol Formardehida Adhesive Supervised by RUDI HARTONO and TITO SUCIPTO. The waste oil palm trunks is a alternative basic commodity manufacture particleboards. The purpose of this study was to evaluate the physical and mechanical properties with the influence temperature and pressing time. Boards were made with size 30 cm x 30 cm x 1 cm with density of 0,70 gr/cm3 . Particleboards using phenol formaldehida adhesive 8%, press 25kg/cm2 and experiments were analyzed by factorial with completely randomized design in 3 temperatures (160, 170 and 180)ºC and 4 pressing times (5, 7, 9, and 11) minutes. Particleboard was tested for density, moisture content, water absorption, thickness swelling, modulus of rupture, compression strength parallel to the surface and internal bond. This result in comparison with SNI 03-2105-2006. Result showed that the value of density, moisture content and internal bond had completed the standard, while thickness swelling and MOR value on some treatment had met standard and the value of MOE did not complete the standard. Optimal condition was attained by combination of pressing temperature of 180ºC and pressing time of 5, 7, 9, 11 minute.
