The objectives of this research were to evaluate of the physical and mechanical properties of oriented strand board (OSB) prepared from acetylated wood strands. Strands derived from Acacia mangium wood were immersed in acetic anhydride for 24 h. After that, strands were dried at 60 C to reach moisture content (MC) of 5%. The slenderness and aspect ratios of strands were 100.72±39.42 and 3.05 ± 0.44. Boards size and target density were set at (25x25x0.5) cm3 and 0.7 g cm-3. The strand compositions for face, core, and back layers were 25, 50, and 25%, respectively. Phenol formaldehyde (PF) resin with amount of 8% was used to bind the strands. The results showed that weight percent gain (WPG) of acetylated strands was 4%. Acetylated strands resulted in improvement of dimensional stabilization (water absorption (WA) and thickness swelling (TS) parameters) with anti-shrink efficiency (ASE) value of 19.65%. On the other hand, the modulus of elasticity (MOE), modulus of rupture (MOR) and internal bond (IB) were found to decrease with acetylation treatment. All the physical and mechanical properties of OSB evaluated except IB parameter fulfilled the requirements of JIS A 5908-2003 standard.Key words: acetylated, anti-shrink efficiency, dimensional stability, oriented strand board

The purpose of this study was to evaluate the physical and mechanical properties of hybrid particleboard made from combination of sengon wood (Falcataria moluccana), jabon wood (Anthocephalus cadamba), and betung bamboo (Dendrocalamus asper) with hot water immersion treatment. Pretreatment with hot water immersion was carried out in water bath at 80 ºC for 2 hours. The boards were made using urea formaldehyde (UF) adhesive with (30x30x0.9) cm3 size and 0.6 g cm-3 target density. Physical and mechanical properties of hybrid particleboards were evaluated based on JIS A 5908-2003 standard. The results showed that the combination treatment with bamboo particles can increase the mechanical properties and dimensional stability of the particleboards especially when combined with jabon particles. Hot water immersion treatment can improve the mechanical properties (MOE, MOR and IB) of hybrid particleboards. However, hot water immersion treatment decreased dimensional stability (thickness swelling and water absorption) of hybrid particleboards.

The objectives of this research is to evaluate the physical and mechanical properties of particle board made from sengon and mangium woods treated with cold water immersion. Particles of sengon and mangium immersed in cold water for 24 hours. The particles of sengon and mangium are combined with a ratio of 100: 0; 0: 100; 75:25; and 50:50. Particle boards are made in size (30x30x0,9) cm3 with target densities of 0.7 g cm-3. The particle board was binded with methylene diphenyl diisocyanate (MDI) adhesive at 10% content and hot press at 140 °C with 25 kgf cm-2 for 7 minutes. The physical and mechanical properties of particle board are evaluated according to JIS A 5908-2003 standard. The physical and mechanical properties of particle board were much affected by particle combination and cold water immersion treatment. The physical (i.e density, moisture content, water absorption (WA), and thickness swelling (TS)) and mechanical properties (ie. modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding (IB)) were evaluated. The results showed that cold water immersion improved dimensional stability (WA and TS) of particle board obtained. However, some mechanical properties decreased.

This research focused on distribution of water borne preservative on woods preserved using full cell and empty cell processes. Retention, penetration, and durability of preserved woods against dry wood termite (Cryptotermes cynochephalus LIGHT) attacked were evaluated. Pine (Pinus merkusii) and sengon (Paraserianthes falcataria) woods were preserved using 5% Wolmanit CB (water soluble preservative) using full cell and empty cell processes. The results indicated that retention of preservative preserved with full cell process was higher than empty cell process. Copper penetration on sengon wood preserved using full cell process was much higher than empty cell process. Distribution of copper and chromium on wood preserved using full cell process evenly distributed through the wood both in pine and sengon woods. They were sharply decreased from outerpart to inner part of wood when preserved using empty cell process. The whole part of pine and sengon woods preserved by either full cell or empty cell processes strongly resistance against dry wood termite attacked. Quantitative analysis of active substance of preservative using atomic absorption spectroscopy (AAS) could detect the preservative in preserved wood more accurately compared using conventional method (retention and penetration tests).Key words: distribution pattern, durability, empty cell process, full cell process, water borne preservative

The objectives of this research were to evaluate the effect of wood species and layer structure on physical and mechanical properties of strand board made from Paraserianthes falcataria, Maesopsis eminii and Acacia mangium woods collected from planted forest in Bogor district, Indonesia. The densities of P. falcataria, M. eminii and A. mangium woods were 0.36, 0.41 and 0.46 g cm-3, respectively. Three types of layer structures namely perpendicular, parallel, and random orientation were applied. Methylene diisocyanate (MDI) resin with 7% resin amount (w/w) was used. The physical and mechanical properties of strand board were evaluated based on CSA 0437.0 standard. The results indicated that strand board manufactured from wood with lower density (P. falcataria) had higher mechanical properties (modulus of rupture, modulus of elasticity and internal bond) and lower dimensional stability (water absorption and thickness swelling) compared to strand board manufactured from higher density (A. mangium), vice versa. Strand orientation strongly affected the physical and mechanical properties of board with perpendicular orientation showed superior performance as compared to parallel and random orientation. Physical and mechanical properties of oriented strand board (OSB) made from fast growing tree species met the requirement of CSA 0437.0 standard for grade O-1 OSB panels.Key words: layer structure, methylene diisocyanate resin, strand board, tropical wood species,

This study designed 7 types of plywood that were arranged by juvenile and mature part of samama (Anthocephalus macrophyllus) wood, The adhesive used was urea formaldehyde with addition of hardener (NH4Cl) in ratio of 100:1 (weight/weight). The adhesive was applied on both surfaces of core veneer, which were loose and tight surfaces, with glue spread was 150 g m-2. The veneers were arranged in accordance with the research design and the resulted structures were then hot pressed at 110 C for 30 seconds per mm of the plywood’s thickness. The pressure was 10 kg cm-2. The results showed that bonding strength of plywood made from juvenile samama veneer was lower than that of the mature one, although the value was still met SNI standard for type I interior plywood. Furthermore, plywood’s moisture content was also met the requirement of the standard. Plywood density was increased by 11-12% from that of the wood. These findings suggest the suitability of both juvenile and mature wood of samama for the material of good quality plywood. Further studies on determination of other veneer-based products, such as laminated veneer lumber (LVL), were then recommended.Keywords: juvenile, mature, plywood, samama, urea formaldehyde

The objectives of this research were to study the density distribution and stress-strain curve (SSC) of oil palm trunk (OPT). The 40 year-old of OPT was used for these experiments. The specimen was taken from 1 m, 3 m and 5 m height of OPT with dimension of (2 x 2 x 2) cm3 for density distribution measurements. The interval of it was 2 cm from the outer near the bark to the inner near the center. The specimen for SSC measurements was taken only from 1 m height with the same dimension, interval, and position, as well. These specimens were treated into three conditions, i.e. air dry, wet and water saturated. The results showed that density of OPT was 0.23-0.74 g cm-3. The stress-strain curves showed that water saturated and wet conditions were easier to compress than that of air dried condition. The compression level increased from the outer to the center of the trunk. The center part can be compressed into 67% in air dry condition and 72-73% in wet and water saturated conditions from their initial thickness. Relationships between compression level, showing by strain, and density expressed as polynomial equations, regardless of the three conditions.Key words: compression, density distribution, OPT, SSC, vascular bundles
