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.

Post-treatment of bamboo-oriented strand board (BOSB) through thermal modification can be an alternative to improve BOSB quality. This study aimed to analyze the effect of post-thermal treatment duration on the physical and mechanical properties of BOSB. Three-layers BOSB with a target density of 0.7 g/cm3 was made with the core layer perpendicular to the surface and bonded with 8% phenol-formaldehyde resin. The BOSB produced was then thermally-modified at 160°C for 1, 2, and 3 h. The physical and mechanical properties of BOSB were determined based on JIS A 5908-2003 standard. The results showed that the physical properties of the thermally-modified BOSB increased while the mechanical properties decreased compared to the untreated BOSB. The moisture content (MC), water absorption (WA), and thickness swelling (TS) of BOSB decreased with the increase in post-thermal treatment duration. The decrease in MC, WA, and TS of the thermally-modified BOSB reached 38.60%, 11.92%, and 33.26%, respectively. In addition, the decrease in modulus of elasticity (MOE), modulus of rupture (MOR), and internal bonding of the thermally-modified BOSB reached 19.18%, 23.15%, and 53.51%, respectively. The results showed that TS, MOE, and MOR of the thermally-modified BOSB still could meet the 0437.0 standards for commercial OSB (Grade O-1). Keywords: bamboo-oriented strand board, Dendrocalamus asper, physical and mechanical properties, post-thermal treatment, treatment duration

This research aimed to analyze the change in chemical composition of the betung bamboo (Dendrocalamus asper) strands after alkali immersion treatment under various immersion times. The bamboo culms were converted into strands with the target length, width, and thickness of 70, 25, and 0.5 mm, respectively. Strands were alkali immersion-treated with 1% NaOH solution for 1, 2, and 3 h. Preparation of powder for chemical component analysis refers to the Technical Association of the Pulp and Paper Industry (TAPPI) standard T 264 cm-07 regarding the preparation of wood test samples for chemical analysis. Structural and non-structural bamboo strand chemical components such as holocellulose, alpha-cellulose, hemicellulose, klason lignin, and extractives were analyzed. The results showed that alkali immersion treatment decreased the hemicellulose content from 21.55% before treatment to 20.30% after 3 h immersion. Thus, it changed the holocellulose and alpha-cellulose composition. Alkali immersion treatment also changed the extractive substances dissolved in cold water, hot water, 1% NaOH, and ethanol-benzene solution. The decrease in hemicellulose, molecular weight lignin, and extractive substances would be beneficial for bamboo-oriented strand board manufacture to improve strand adhesion, dimensional stability, mechanical properties, and durability against biological agents attack. Keywords: alkali immersion times, alkali immersion treatment, bamboo, chemical components, pre-treatment
