• Physical and mechanical properties of jabon wood particleboards were studied. The wood particle from lower, upper parts of trunk and branches of jabon tree were used. The wood wettability was observed at lower, upper part of trunk and branches of 2.5 years old jabon tree from Cihideung Ilir village, Bogor. The quality of particleboard in terms of density, moisture content, thickness swelling, modulus of elasticity, modulus of rupture, internal bond, and screw holding power were tested accordance with JIS 5908:2003. In general partikel bord made of jabon wood from upper, lower of trunk and branches of jabon were as follow: density (0.61 g/cm3, 0.58 g/cm3, 0.65 g/cm3), moisture content (9.9%, 9.7%, 9.3%), thickness swelling (44.8%; 52.3%; 30.6%), modulus of elasticity (9716.1 kg/cm2, 7997.4 kg/cm2, 12954.3 kg/cm2), modulus of rupture (82.6 kg/cm2, 71.3 kg/cm2, 90.8 kg/cm2), internal bond (5.06 kg/cm2, 3.02 kg/cm2, 6.12 kg/cm2) and screw holding power (30.6 kg/cm2, 38.8 kg/cm2, 47.5 kg/cm2), respectively. The quality of jabon wood were not affected by the precentage of adhesive used. There were a variability in wettability of jabon wood between parts of tree. The wettability of jabon wood of upper, lower trunk and branches were 1800.4, 2126.1 and 2169.7 mm, respectively. Furthermore, the variabilities were also happened in almost all physical dan mechanical properties of the particleboard. The higher the wettability the higher the quality of the particleboard, means that wettability as a good indicator for quality of jabon woods particleboard.The quality of particleboard made of woods from branches were better than others.

• The qualities of core kenaf particle boards were studied. The boards were made of core kenaf particles and their liquids fortified by melamine formaldehyde. Core kenaf liquids were prepared using 20 – 60 mesh particles, phenol : formaldehyde ratio of 0,5, based on Masri (2005). SNI 06-4567-1998 and JIS A 5908-2003 were used to grade the kenaf liquids and particle board. Factorial analysis 3 x 3 in Complete Randomized Design was applied with 2 replications. Glue spread with 3 levels (10, 15 and 20% of the oven dry weight kenaf particles) and fortification MF with 3 levels (15, 30 and 45% of the solid content of the kenaf liquids) were used. Kenaf particles were cold soaked prior bonding. The condition of bonding operation in making particle board were : pressure of 20 kgf/cm2 at 160oC for 12 minutes. The best result of particle board produced by 20% glue spread and 45% MF fortification with the properties as follows : density of 0,7 g/cm3, moisture content of 6,6%, water absorb ability of 55,6%, thickness swelling of 16,6%, screw holding strength of 641,2 N, internal bond of 0,86 N/mm2, MOE of 2131,9 N/mm2, and MOR of 15,3 N/mm2. Fortifications doesn’t significantly affect the quality of the particle boards. Keywords: Core-kenaf, kenaf liquids, fortification
