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.

Development of bamboo as an alternative material for particleboard production has been increasing due to its fast growth, high productivity, high strength property, and light weight. The aims of this study were to determine the effects of particle pre-treatment on the durability and dimensional stability of particleboard. Particles were made from betung (Dendrocalamus asper)/B, jabon (Anthocepallus cadamba)/J, and sengon (Falcataria moluccana)/S pretreated by steam and hot water immersion. Five combinations of particleboard consisted of three homogenous boards (B-B-B, J-J-J, S-S-S) and two hybrid-particleboards (J-B-J, S-B-S) were manufactured using urea formaldehyde of 10% resin level and target density of 0.6 g cm-3. Durability of particleboards was evaluated by grave-yard test and the dimensional stability of particeboards was determined by measuring thickness swelling during a wet-dry cyclic test. The results showed that pre-treatment on particles significantly improved the durability and dimensional stability of the boards, showing lower weight loss and thickness swelling than control boards. Homogenous wood particleboards (J-J-J and S-S-S boards) showed higher weight loss and thickness swelling than bamboo particleboard (B-B-B), combining wood and bamboo particles into hybrid-particleboards (J-B-J and S-B-S boards) has improved the durability and dimensional stability of the boards.

Perlakuan steam dan bilas NaOH 1% telah diketahui meningkatkan sifat fisis dan mekanis Oriented Strand Board (OSB) bambu. Peningkatan tersebut disebabkan oleh menurunnya kadar zat ekstraktif dan komponen berbobot molekul rendah lainnya pada bambu. Selain itu, steam dan bilas NaOH 1% juga diduga mempengaruhi keasaman bambu. Penelitian ini bertujuan untuk menentukan perubahan keasaman yang terjadi akibat perlakuan steam dan bilas NaOH 1% pada enam jenis bambu Indonesia. Enam jenis bambu meliputi bambu andong, betung, tali, ampel, kuning, dan hitam digunakan pada penelitian ini. Sampel bambu dicacah hingga berbentuk partikel dan diberikan dua perlakuan berbeda yaitu steam dan steam + bilas NaOH 1%. Partikel bambu kemudian digiling hingga didapatkan serbuk berukuran 40-60 mesh. Serbuk bambu diekstrak dengan air panas selama 1 jam. Nilai pH filtrat ekstrak diukur menggunakan pH meter. Ekstrak kemudian dititrasi dengan larutan H2SO4 0,025 N hingga pH 4 dan larutan NaOH 0,025 N hingga pH 10. Jumlah larutan penyangga yang ditambahkan ke dalam ekstrak dinyatakan sebagai kapasitas penyangga asam dan basa. Hasil penelitian menunjukkan bahwa jenis bambu dan perlakuan berpengaruh terhadap nilai pH dan kapasitas penyangga. Nilai rata-rata pH enam jenis bambu berkisar 5,20-6,67 dan meningkat setelah perlakuan steam dan Steam + bilas NaOH 1% berturut-turut menjadi 5,97-6,78 dan 7,02-7,63. Kapasitas penyangga asam dan basa enam jenis bambu masing-masing berkisar 0.404-0.525 mmeq dan 0.095-0.1750 mmeq dan meningkat setelah perlakuan steam dan Steam + bilas NaOH 1%.

The objective of this research was to evaluate the effect of preservative treatment of strands on the properties of oriented strand board (OSB) made from Paraserianthes falcataria, Maesopsis eminii and Acacia mangium strands. Prior to OSB manufacturing, strands were treated with chromium copper boron (CCB) soaking with concentration of 2% for 6 h. Three (3) layers OSB bonded with 7% of methylene diphenyl isocyanate (MDI) resin were produced with the core layer orientation perpendicular to the face and back layers. The results indicated that soaking strand with CCB significantly decreased the water absorption (WA) and thickness swelling (TS) values of OSB after immersed in water for 24 hours. Preservative treatment significantly decreased the mechanical properties of OSB (modulus of rupture/MOR parallel, modulus of elasticity/MOE parallel and internal bond/IB). Almost all board met the requirement of CSA 0437.0 standard for grade O-1 OSB panels, except board made from P. falcataria treated with preservative which did not achieve the requirement of TS, MOE in parallel direction, and IB. Preservative treatment strongly affected the durability of OSB. Soaking strand with CCB increased the resistance of OSB against termites attack 13.0 times higher than control board.Key words: chromium copper boron, fast growing tree species, methylene diphenyl isocyanate, oriented strand board

Natural fibers of kapok and balsa can be potential renewable raw material for reinforced polymer composite. Alkaline treatment carried out in the present works was intended to develop the physical and chemical properties of the fibers before its application in reinforced composites preparation. The treatments involve of using NaOH at the concentration of 2, 4, 6, 8 and 10%. The change of morphological characteristics, crystallinity index, functional groups, and water contact angle were analyzed by using SEM, FTIR, XRD and contact angle analyzer, respectively. Upon alkaline treatments, the fibers were clean, flatten, and the surface tended to be rough. Defibrillation occurred at higher alkaline concentration. Alkaline treatment on the fibers shifted and changed the peak absorption intensity of -OH, C-O, C=C and C=O. Up to 8% NaOH concentration, alkaline treatment increased the crystallinity of the fibers, however decreased when the concentration of NaOH reaching 10%. Alkaline treatment on the fibers removed lignin, hemicellulose, and waxy substance of the fiber surface, increased surface roughness, and therefore is expected to create better interfacial adhesion.

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 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
