PENGUJIAN KEAWETAN ALAMI PAPAN PARTIKEL DARI CAMPURAN LIMBAH BATANG SORGHUM DAN SERUTAN KAYU
ABSTRACT: Sorghum stalk
bagasse is potential raw materials to particleboard manufacture. In the
previous research, sorghum bagasse particleboard had weakness matter in modulus
of elasticity, internal bond and thickness swelling properties. Wood shaving
mixture will be expected to improve of those properties. The objective of this
research was to evaluate the effect of wood
shaving added to improve mechanical properties of particleboard. Wood shaving type was added in particleboard
manufacturing consist of Meranti, Cempedak, Mahoni, and Durian. Sorghum bagasse and wood shaving ratio in
this research was 50/50 (%w/w). Amount of 10% urea formaldehyde (UF) resin used
for binding. Hot pressing process was conducted in 1300C temperature for 10
minute and 30 kg cm-2 pressure. The
result showed that, the thickness swelling (TS) does not fulfill of requirement
JIS A 5908 (2003). Cempedak and Mahoni wood shaving mixture resulted of lower
the TS value than control and other wood shaving mixture. In generally, wood
shaving and sorghum bagasse mixture result in increasing of internal bond properties.
Cempedak wood shaving resulted the best of bending properties than control and
other mixture.
