This study designed 7 types of plywood that were arranged by juvenile and mature part of samama (Anthocephalus macrophyllus) wood, The adhesive used was urea formaldehyde with addition of hardener (NH4Cl) in ratio of 100:1 (weight/weight). The adhesive was applied on both surfaces of core veneer, which were loose and tight surfaces, with glue spread was 150 g m-2. The veneers were arranged in accordance with the research design and the resulted structures were then hot pressed at 110 C for 30 seconds per mm of the plywood’s thickness. The pressure was 10 kg cm-2. The results showed that bonding strength of plywood made from juvenile samama veneer was lower than that of the mature one, although the value was still met SNI standard for type I interior plywood. Furthermore, plywood’s moisture content was also met the requirement of the standard. Plywood density was increased by 11-12% from that of the wood. These findings suggest the suitability of both juvenile and mature wood of samama for the material of good quality plywood. Further studies on determination of other veneer-based products, such as laminated veneer lumber (LVL), were then recommended.Keywords: juvenile, mature, plywood, samama, urea formaldehyde

The objectives of this research were to study the density distribution and stress-strain curve (SSC) of oil palm trunk (OPT). The 40 year-old of OPT was used for these experiments. The specimen was taken from 1 m, 3 m and 5 m height of OPT with dimension of (2 x 2 x 2) cm3 for density distribution measurements. The interval of it was 2 cm from the outer near the bark to the inner near the center. The specimen for SSC measurements was taken only from 1 m height with the same dimension, interval, and position, as well. These specimens were treated into three conditions, i.e. air dry, wet and water saturated. The results showed that density of OPT was 0.23-0.74 g cm-3. The stress-strain curves showed that water saturated and wet conditions were easier to compress than that of air dried condition. The compression level increased from the outer to the center of the trunk. The center part can be compressed into 67% in air dry condition and 72-73% in wet and water saturated conditions from their initial thickness. Relationships between compression level, showing by strain, and density expressed as polynomial equations, regardless of the three conditions.Key words: compression, density distribution, OPT, SSC, vascular bundles

The high of pH of jatropha fruit hulls causes the negative properties of particleboard made from this material. Adjusting the particle acidity and pressing conditions (temperature and time) is among the technical modifications available to improve this particleboard’s properties. Particle acidity has been adjusted in a previous research project, and immersing the particles in acetic acid was found to be the best treatment in this preliminary research. In order to improve the particleboard’s properties, an experiment was conducted to determine the best pressing temperature and time. The objective of the research was to evaluate the influence of pressing temperature and time on the physical and mechanical properties of the board. Jatropha fruit hulls were immersed in 1% acetic acid solution for 24 hours. UF resin was used as the adhesive in the amount of 10%. The pressing temperatures and times used in this research were 110 °C, 120 °C, and 130 °C for 8 and 10 minutes, respectively. The particleboards were tested to determine their physical and mechanical properties according to JIS A 5908-2003. The result showed that pressing at 130 °C for 10 minutes resulted in the best physical and mechanical properties. Increasing the pressing temperature at a constant time or increasing the pressing time at a constant temperature caused the particleboard to exhibit decreased water absorption. The thickness swelling and modulus of elasticity (MOE) of the particleboard did not fulfil JIS A 5908-2003.

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.

Modified lignin with improved reactivity can be a potential alternative for synthetic phenol formaldehyde resin for the adhesive of wood composite. Direct hydroxymethylation of kenaf in the present experiments was intended to increase lignin reactivity, and therefore was expected to result in satisfying properties of binderless MDF. The stem of kenaf was refined in a disk refiner and the refined fibers were hydroxymethylated in various levels of alkalinity. The concentration of NaOH during hydroxymethylation was of 3%, 6% and 12%. Wet process was applied to produce MDF (30 cm x 30 cm x 1 cm) with target density of 0.65 g/cm³. Physical and mechanical properties of MDF were measured in accordance with the standard procedure of JIS A 5905: 2003. Chemical changes in the surface of pulp and the change of board crystallinity were evaluated by FTIR-KBr method and X-Ray Diffractometry (XRD), respectively. Density, moisture content, and screw withdrawal of the board increased with increasing of NaOH concentration. Thickness swelling, water absorption, MOE and MOR increased up to 3% concentration of NaOH. The IB and heat conductivity of MDF were not influenced by NaOH concentration. Increasing OH groups due to hydroxymethylation was thought to be the origin of high water absorption and thickness swelling of the resulting boards. Higher alkalinity during hydroxymethylation stage was likely increasing cellulose crystallinity that brought about increasing board density. However, chemical modification of the fiber was thought to be more influential to the bending strength and stiffness of the resulting fiberboard. Hydroxymethylation of kenaf pulp was successfully improved board properties. Except for the moisture content, thickness swelling and internal bonding (at 0% and 3% NaOH concentration), all properties of the MDF satisfied the requirement of JIS A 5905: 2003 (type 5) standard. MDF Tanpa Perekat dari Pulp Kenaf TerhidroksimetilasiIntisariLignin yang telah ditingkatkan reaktifitasnya dapat menjadi bahan alternatif perekat resin sintetis fenol formaldehida. Reaktivitas lignin dapat diperbaiki melalui hidroksimetilasi. Dalam penelitian ini, batang kenaf digiling menggunakan disk refiner, dan selanjutnya dilakukan hidroksimetilasi pada beragam alkalinitas. Konsentrasi NaOH yang digunakan dalam hidroksimetilasi bervariasi dari 3%, 6% dan 12%. Proses basah diterapkan untuk membuat MDF (30 cm x 30 cm x 1 cm) dengan target kerapatan 0,65 g/cm3. Sifat fisis dan mekanis MDF diukur mengikuti prosedur standar JIS A 5905: 2003. Perubahan gugus fungsi permukaan pulp dan tingkat kristalinitas papan masing-masing dievaluasi menggunakan FTIR-metode KBr dan difraksi sinar X (XRD). Hasil penelitian menunjukkan bahwa konsentrasi NaOH tidak mempengaruhi IB dan konduktivitas panas MDF. Kerapatan, kadar air, dan kuat pegang sekrup cenderung meningkat dengan meningkatnya konsentrasi NaOH. Pengembangan tebal, daya serap air, MOE, dan MOR meningkat sampai dengan hidroksimetilasi dalam NaOH konsentrasi 3%. Peningkatan gugus OH serat akibat hidrosimetilasi diduga meningkatkan penyerapan air dan pengembangan tebal papan yang dihasilkan. Alkalinitas hidroksimetilasi yang lebih tinggi meningkatkan gugus cincin aromatik yang menunjukkan bahwa reaksi formaldehida berlangsung dengan lebih baik. Peningkatan alkalinitas dalam hidroksimetilasi meningkatkan kristalinitas selulosa. Peningkatan kristalinitas selulosa diduga berkontribusi dalam meningkatkan kerapatan, namun perubahan gugus kimia serat diduga lebih berpengaruh terhadap MOR dan MOE dari papan serat yang dihasilkan. Hidroksimetilasi pulp kenaf berhasil meningkatkan sifat papan. Kecuali untuk kadar air, pengembangan tebal dan IB (pada hidroksimetilasi dalam 0% dan 3% NaOH), semua sifat-sifat dari MDF yang dihasilkan memenuhi persyaratan standar JIS A 5905: 2003 (tipe 5).

The objective of this study was to assess the properties of cross-laminated timber (CLT) fabricated from the combination of Sumatran pine (P) and coconut trunk (C) bonded with polyurethane adhesive. The basic properties of raw materials and adhesives were characterized. The CLT panels’ length, width, and thickness are 100 cm by 30 cm by 3.6 cm, respectively. Three-layer CLT was made with 4 combinations of face/core/back lamina, i.e., PPP, CCC, PCP, and CPC, which are arranged perpendicular to each other. The laminae were bonded using PU adhesive on 160 g.m-2 glue spread. The CLT’s delamination and wood failure percentages (WFP) were assessed following the JAS 3079 (2019) standard. The study’s results demonstrated that the PU adhesive employed in this investigation could curl ideally at 30°C for 200 min. Solid pine and coconut’s physical and chemical characteristics differed, but their wettability to polyurethane adhesives was identical. Hybrid pine CLT has greater attributes compared to single pine CLT. Single coconut CLT, on the other hand, offers better features than hybrid coconut CLT. All CLT samples failed to fulfil the JAS 3079 (2019) requirement for delamination (=< 10%) and WFP (>= 90%).
