“…Fast-growing wood species have the characteristics of small diameter, low quality, and contain many juvenile woods, resulting in low wood yield (Cahyono et al 2017;Suri et al 2021). Afrika wood has a specific gravity of 0.37 (Kim et al 2012(Kim et al , 2014), strength class of IV (Karlinasari et al 2021), and durability class of IV (Febrianto et al 2015). Mangium wood has a specific gravity of 0.46-0.52, strength class of III (Somadona et al 2020), and durability class of IV (Febrianto et al 2015a).…”

The objective of this study was to determine the physical and mechanical properties of oriented strand board (OSB) from three wood species of plantation forests, i.e., Afrika (Maesopsis eminii), mangium (Acacia mangium), and sengon (Paraserianthes falcataria) at various resin contents. OSB was made with a shelling ratio (face:core:back) of 1:2:1 and a target density of 0.6 g/cm3. Methylene diphenyl di-isocyanate (MDI) adhesive was used with 3%, 5%, and 7% resin contents. The physical and mechanical properties were evaluated based on JIS A 5908:2003 standard and the values were compared with CSA 0437.0 (Grade O-1) standard. The results show that the physical and mechanical properties of the OSB were improved as the resin content increased for all wood species. OSB prepared from Afrika and mangium wood strands with 7% resin content showed better physical and mechanical properties than the other OSBs. Thickness swelling of OSB prepared from three wood species had met the CSA O437.0 (Grade O-1) standard. All OSBs produced in this experiment met the standard for MOR parallel and perpendicular to the grain. OSB from three wood species with a 5% and 7% resin content met the standard for MOE perpendicular to the grain. Only mangium OSB with a resin content of 7% met the standards for MOE parallel to the grain. Afrika OSB with 5% and 7% resin content, mangium OSB with 5% resin content, and sengon OSB with 3% and 7% resin content met the standard for the internal bond.

“…Therefore, there could be a difference in wood quality between the woods produced from natural forests and those from plantation forests. Previous studies (Kim et al 2012;Jang et al 2014;Kim et al 2014) on the characteristics of plantation wood have provided identification and utilization indicators of infrequently used species grown in the tropical zone. However, information regarding recently planted species and promising species is still inadequate as an indicator for effective utilization.…”

This study was conducted to provide foundational anatomical information of three infrequently used wood species growing in tropical areas. Three species of the genus Syzygium, namely the clove tree, kupa, and spicate eugenia, were selected. The representative anatomical features of these species were classified using the International Association of Wood Anatomists (IAWA) anatomical feature list. The representative anatomical features of the clove tree included the distribution of small vessels with tangential diameters of approximately 60 µm in cross-surface, a dense spacing of vessels, the axial parenchyma in narrow bands or lines up to three cells wide, and the body ray cells procumbent with over four rows of upright and/or square marginal cells. The kupa showed axial parenchyma confluent and the body ray cells were procumbent with over four rows of upright and/or square marginal cells. In the spicate eugenia, the axial parenchyma was diffused in aggregate with exclusively uniseriate rays and the body ray cells were procumbent with one row of upright and/or square marginal cells. These three species were easily identified by optical microscopy via the anatomical features of the woods.

“…Wood properties have been investigated for several fast-growing tree species planted in Indonesia, such as F. moluccana (Ishiguri et al 2007;Fajriani et al 2013), Gmelina arborea (Kim et al 2012;Hidayati et al 2017), and A. cadamba (Fajriani et al 2013;Seo et al 2015;Pertiwi et al 2017). However, available information is limited on the wood properties of other fast-growing tree species grown in the community forest in Indonesia.…”

Community forests in Indonesia are important suppliers of wood resources for the wood industry. In the present study, stress-wave velocity of stems, log characteristics (taper, green density, and dynamic Young s modulus), and wood properties (basic density, compressive strength parallel to grain, modulus of elasticity [MOE], and modulus of rupture [MOR]) were investigated for three fast-growing tree species grown in community forests in Indonesia: Acacia mangium Willd., Maesopsis eminii Engl., and Melia azedarach L. Based on the bending properties, the MOE values of laminae (30 150 mm in cross-section) and glulam (six layers, 90 150 mm in cross-section) were simulated. The mean values of simulated MOE in the laminae were 8.93, 6.82, and 8.63 GPa for A. mangium, M. eminii, and M. azedarach, respectively. When the laminae from a species were randomly laminated, the simulated MOE values of glulam were 8.94, 6.82, and 8.66 GPa for A. mangium, M. eminii, and M. azedarach, respectively. When laminae with a high, medium, and low MOE were laminated at outer, middle, and inner layers of glulam, respectively, the simulated MOE values of glulam increased by about 5 % to 15 % compared to the values of a randomly laminated one. It is concluded that glulam with a high MOE can be produced from fast-growing tree species grown in community forests in Indonesia.
