Oil palm wood (OPW) has several imperfections, and impregnation with low molecular- weight phenol formaldehyde resin through a modified compreg method can practically enhance these properties. The treated OPW, however, releases a considerable amount of free formaldehyde and thus is unhealthy for the human being. To make it applicable for indoor material, formaldehyde emission (FE) should be lowered to 0.1 ppm or lower. The FE level of the treated OPW was reduced from 0.3 to 0.1 ppm or lower by improving the resin curing state through two approaches, i.e. modifying the hot pressing compression schedule during the process and adopting an extended drying after the process. It is acknowledged that the extended drying gave more effect on the FE reduction than that of modifying hot-pressing schedule. The combination pressing schedule of 12.5%®25%®50% and extended drying of 48 h emits the lowest, safe formaldehyde of 0.08-0.10 ppm, which is considered safe according to American National Standard Institute (ANSI) standard. The improving resin curing state through modifying the hot pressing schedule and adopting extended drying could be used as a practical way to reduce the FE level of the treated OPW to a safe level suitable for various furniture and indoor applications.

The main weaknesses of particleboard are that it has a lower strength and a lower dimensional stability compared to solid wood. Therefore, in order to gain excellent properties prior to be used, it needs some treatments, i.e., resin thermoplastic laminated. The objectives of this study were to improve the physical and mechanical properties of rubber wood particleboard laminated with low density ethylene (LDPE) resin. Rubber wood particleboard was laminated with 4 different concentrations of LDPE resins (i.e., 5, 10, 15, and 20%). The physical and mechanical properties of board were evaluated both in dry and wet states. The results indicated that the dimensional stability of board after laminated with LDPE resin showed significant improvement in term of water absorption and thickness swelling. Modulus of rupture and srew resistant of resulted particle board were increased with addition of LDPE resin. Modulus of elasticity and surface hardness of the particleboard were slightly decreased with addition of LDPE resin. The intenal bond was unchanged. The best treatment was found on lamination the surface of particleboard with 5% LDPE resin. All the physical and mechanical properties of particleboard laminated with 5% LDPE resin met the requirements of JIS A 5908-2003 standard.Key words: dimensional stabilization, low density polyethylene, mechanical properties, particleboard

The objectives of this research were to evaluate the extractive substances of heartwood of Kupa wood (Syzygium polycephalum (Mig)) and its potention as bio-active substance to wood destroying fungi i.e., Schizophyllum commune Fr and Pleurotus sp. Successive extraction method was used in this experiment. The heartwood part was then converted into 40 mesh wood flour and followed by extraction using methanol, chloroform, ethyl acetate, n-hexane and buthanol solvents. The extractives obtained were subjected to wood destroying fungi S. commune and Pleurotus sp. The results indicated that the extractive content of S. polychephalum mostly dominated by substance diluted in chloroform (2.87%), followed by ethyl acetate (0.38%), n-hexane (0.33%) and buthanol (0.05%). All the wood extracts of S. polychephalum potentially contain anti-fungal compound to inhibit the growth of S. commune Fr and Pleurotus sp fungi. N-hexane and ethyl acetate extracts of S. polychephalum are the most active extracts. Isolation of ethyl acetate fraction resulted in nine (9) active compounds (G.1-G.9) that could inhibit the growth both S. commune and Pleurotus sp with IC(50) values 49.33-61.71 ppm and 48.84-64.61 ppm, respectively. It was found that G.2 compound of ethyl acetate has anti fungal substance namely 3-O-glucosyl-3’,4’ 5-trihydroxyflavonol.

The objective of this research was to evaluate the properties of particleboard made from mixtures of jatropha fruit hulls (JFH) and wood particle in several mixture ratios. JFH, and mangium wood (Acacia mangium Wild) particle were untreated and treated with 1% acetic acid solution for 24 h. Urea formaldehyde (UF) resin with 10% resin content (SC: 63%) was used as binder. The ratio of JFH and wood particles were set at 100:0, 70:30, 60:40, 50:50, and 0:100. The target density of particleboard was set at 0.70 g cm-3. The temperature and pressure of hot pressing were set at 130 ºC and 2.544 N mm-2 for 10 minutes. The physical and mechanical properties of particleboard were evaluated according to JIS A 5908-2003 standard. The result indicated that addition of untreated mangium wood particle onto JFH particles improved mechanical properties of board especially modulus of elasticity (MOE) and modulus of rupture (MOR) parameters. However, the internal bond (IB) parameter was found to decrease with addition of wood particle. The higher amount of wood particle added resulted in the better the MOR and MOE parameters. Addition of acetic acid treated mangium wood particle onto JFH particleboard resulted in lower physical and mechanical properties.Key words: Jatropha curcas, fruit hulls, particleboard, wood particle

The objective of this study was to evaluate the physical and mechanical properties of bamboo oriented strand board (OSB) from andong (Gigantochloa pseudoarundinacea) with steam treatment on strand at various shelling ratios. Strands were steam-treated at 126 ºC for 1 h under 0.14 MPa pressure. Three-layer OBSB with the core layer perpendicular to the surface at various shelling ratio (15/70/15, 20/60/20, 25/50/25, 30/40/30) was formed and bonded with 8% of phenol formaldehyde resin. Wax was added amount of 1% based on oven dry strand. The evaluation of physical and mechanical properties of the boards was conducted in accordance to the JIS A 5908:2003 standard. Steam treatment tended to increase the dimensional stability and mechanical properties of OBSB from andong. The higher shelling ratio increased the parallel flexural properties, but decreased the perpendicular flexural properties.

Steam and rinsing treatment with water and 1% NaOH solution of andong bamboo strands have been known to improve physical and mechanical properties of its oriented strand board (OSB). The improvement of bamboo OSB properties might be caused by the change of chemical components content during steam and rinsing process. This study aims to measure the changes of chemical components content in andong bamboo (Gigantochloa pseudoarundinacea) due to steam treatment and rinsing with water or sodium hydroxide solution. Samples was taken from andong bamboo stem without bark and node part. The treatments of samples were steam at 126 ° C for 1 hour, steam and rinsing with water, and, steam and rinsing with 1% NaOH, respectively. Air-dried samples were, then, subjected to mill in order to get 40-60 mesh particles size, which was used for chemical components analyses. The results showed that steam and rinsing with water or 1% NaOH solution treatment reduced hemicellulose and extractive contents (dissolved in cold water, hot water, ethanol-benzene and NaOH 1% solution), whereas alpha-cellulose and lignin were relatively stable. Steam and rinsing treatment generally increased the pH value of bamboo samples.

Penelitian ini bertujuan untuk mengevaluasi ketahanan oriented strand board (OSB) dari bambu betung (Dendrocalamus asper) (BOSB) dengan perlakuan steam pada strand terhadap cuaca. Strand diberi perlakuan steam pada suhu 126 ºC di bawah tekanan 0,14 MPa selama 1 jam. Tiga lapis BOSB dibuat dengan kerapatan target 0,7 g cm-3 yang direkat dengan perekat fenol formaldehida (PF) dengan konsentrasi 8%. Parafin ditambahkan sebanyak 1% dari berat kering oven strand. Bamboo oriented strand board dipaparkan pada cuaca terbuka di Dramaga, Kabupaten Bogor Jawa Barat (6°34’15.72’’Selatan 106°44’17.30’’Timur). Evaluasi sifat fisis dan mekanis BOSB sebelum dan sesudah dipaparkan di udara selama 2 dan 3 bulan dilakukan berdasarkan standar JIS A 5908:2003. Penentuan nilai nisbah retensi MOE dan MOR dilakukan dengan membandingkan nilai MOE dan MOR sebelum dan sesudah pemaparan. Hasil penelitian menunjukkan bahwa perlakuan steam pada strand dapat meningkatkan stabilitas dimensi dan sifat mekanis BOSB. Pemaparan BOSB pada cuaca terbuka dapat menurunkan stabilitas dimensi dan kekuatan BOSB. Ketahanan BOSB dengan perlakuan steam pada strand terhadap pemaparan alami lebih tinggi dibandingkan dengan tanpa perlakuan steam.
