People are less interest to the fast growing species since the quality is inferior compared to commercial wood. A research has been done to identify the physical and mechanical properties of samama wood (Antocephalus macrophylus (Roxb.)) from Mollucas island. Eight years old samama wood with diameter of 30 - 45 cm and height of 8 – 11 meter were used as samples. The parameters measured were moisture content (MC), specific gravity (SG), tangential and radial shrinkages, bending strength (MOR and MOE), tension and compression strengths parallel to grain and hardness. The result showed that the MC of samama wood decreased from bottom to upper and from outer to inner parts, while SG decreased from bottom to upper and from inner to outer part. Tangential and radial shrinkages of samama wood were much affected by vertical position. The MOE and MOR of samama wood decreased from bottom to upper part, while tension and compression strengths parallel to grain direction decreased form inner to outer part. On the other hand, hardness of samama wood decreased from bottom to upper and from inner to outer parts. Based on PKK NI5-1961 classification, samama wood belonged to strength class of III and IV.Key words: mechanical properties, Mollucas Island, physical properties, samama wood

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.

Hybrid Bamboo Oriented Strand Boards (OSB) were produced to improve bamboo OSB's physical and mechanical properties. Shelling ratio adjustment of the strand type combination could determine the optimal physical and mechanical properties of hybrid bamboo oriented strand boards (OSB). The purpose of this study was to evaluate the physical and mechanical properties of hybrid betung and andong bamboos OSB at various shelling ratios. Steam modified strands of betung and andong bamboo were used as an outer layer and core layer, respectively. Hybrid bamboo OSBs were prepared with 0.7 g cm-3 target density and 8% phenol-formaldehyde resin content. Three layers of OSB were made with outer: core shelling ratios of 30:70, 40:60, 50:50, and 60:40. The physical and mechanical properties of the OSB were tested referring to the JIS A 5908-2003 standard. The targeted board density was achieved and the physical properties of all hybrid bamboo OSB have met the requirement of CSA O437.0 (Grade O-1) standard criteria. The parallel modulus of elasticity (MOE) and modulus of rupture (MOR) increased with increasing outer layer ratio. However, the perpendicular MOE and MOR decreased with increasing outer layer ratio. The internal bonding (IB) of the OSB with a shelling ratio of 30:70 and 40:60 met with the requirement of the CSA O437.0 (Grade O-1) standard.

Bamboo has good prospects for composite raw materials such as for Oriented Strand Board (OSB) product. Previous research has shown that steam and rinsing with water and 1% NaOH solution treatments of strand improved the properties of OSB, which might be caused by changing in the chemical components content of bamboo. This study aimed to determine the chemical components content change of sembilang bamboo (Dendrocalamus giganteus Munro), black bamboo (Gigantochloa nigrocillata Kurz.), and tali bamboo (G. apus (Bl.ex Schult.f.)) due to steam and rinsing treatment. The chemical components of bamboo were analyzed referring to the Technical Association of the Pulp and Paper Industry standards (TAPPI). The results showed that the most significant changes in the chemical components content of bamboo occured for holocellulose, hemicellulose, extractive contents, and pH values. The decreasing of hemicellulose, extractive contents, and increasing pH values due to the steam and 1% NaOH rinsing treatment may improve the adhesion quality of OSB.
