The objectives of this research were to analyze the physical and mechanical properties of Oriented Strand Board (OSB) prepared from steam treated betung bamboo (Dendrocalamus asper) strands under various adhesive combinations. The strands were steamed at 126 °C for 1 h with the pressure of 1.4 kg cm-2 prior to be blended with adhesive. Three-layered OSBs with the core layer orientation perpendicular to the face layers were prepared by bonding using 5% methylene diphenyl diisocyanate (ISO), 7% phenol formaldehyde (PF), combination of ISO:PF:ISO and PF:ISO:PF adhesives. Paraffin in amount of 1% was added as an additive. The strand ratio for face, core, and back layers was 1:1:1, respectively.The results indicated that the physical properties i.e., water absorption and thickness swelling, and mechanical properties i.e., modulus of rupture and modulus of elasticity both parallel and perpendicular to the grain direction and internal bond of OSB bonded ISO and combination of ISO:PF:ISO adhesives were much better than that of bonded with combination PF:ISO:PF and PF adhesives. Almost all parameters of OSB tested in this experiment were higher than the minimum criteria requirement of CSA 0437.0 (Grade 0-2) standard, except the value of MOE perpendicular to the grain direction of OSB bonded with PF adhesive.Key words: betung bamboo, isocyanate, oriented strand board, phenol formaldehyde, steam

Bamboo is multipurpose plant and is traditionally used by Indonesian rural community to substitute wood for housing material. Bamboo is susceptible to termite and powder post beetle. Consequently, bamboo and its derivative products have relatively short service life. Most available information regarding the natural durability of bamboo in Indonesia was acquired based on various different methods and are less accurate. The present research was aimed to analyze the natural durability of ampel bamboo (Bambusa vulgaris Schrad. Ex Wendl), betung bamboo (Dendrocalum asper), andong bamboo (Gigantochloa verticillata), hitam bamboo (Gigantochloa atroviolaceae) and tali bamboo (Gigantochloa apus)) against subterranean termite (Coptotermes curvignathus), dry wood termite (Cryptotermes cynocephalus), and powder post beetle (Anobium sp) referring to SNI 01.7207-2006. The results showed that bamboo species determined its natural durability against C. curvignathus, C. cynocephalus and Anobium sp. Natural durability of tali bamboo, betung bamboo, and hitam bamboo against C. curvignathus belonged to the 2nd class (resistant), while andong bamboo and ampel bamboo belonged to the 4th class (poor). Natural durability of non-barked hitam bamboo, and andong bamboo against C. cynocephalus belonged to the 3rd class (medium), while those of tali bamboo, betung bamboo, and ampel bamboo belonged to the 4th class (poor). Natural durability of all barked bamboos species against C. cynocephalus were categorized to the 4th class (poor). The resistance of ampel bamboo and andong bamboo against Anobium sp were lower compared to those of tali bamboo, hitam bamboo, and betung bamboo.Keywords: bamboo, dry wood termite, natural durability, powder post beetle, subterranean termite

The objective of this research was to evaluate the resistance of bamboo oriented strand board (BOSB) prepared from steamed and non-steamed strands of five (5) bamboo species against subterranean termite (Coptotermes curvignathus), dry wood termite (Cryptotermes cynocephalus), and powder post beetle. The five bamboo species were betung, andong, ampel, hitam, and tali. In steaming treatment, bamboo strands were steamed in autoclave at 126 °C and 1.4 kg cm-2 pressure for 1 h prior mixing with adhesive. Strands were bonded into BOSB by the use of commercial Phenol formaldehyde (PF) adhesive at 10% (w/w) of oven dried strands. The resistance of BOSB against termite was done based on SNI 01.7207-2006 procedures and requirement. The results indicated that the resistance of BOSB against termites was significantly affected by bamboo species and steam treatment. The resistance of BOSB prepared from steamed bamboo strands against C. curvignathus and C. cynocephalus was higher than that of non-steamed bamboo strands particularly that of ampel bamboo strands. The powder post beetle was identified as Anobium sp. Bamboo species and strands steaming did not significantly influence the resistance of BOSBs against Anobium sp.Key words: bamboo, dry wood termite, oriented strand board, powder post beetles, subterranean termite

In this study, activated carbon was prepared using hydrochar derived from oil palm shell through hydrothermal carbonization (HTC), and activated by 5% kalium hydroxide (KOH). The activation process was carried out using a temperature of 700 °C - 800 °C, with activation time of 60-120 minutes. The parameters of the activation process were optimised by response surface methodology (RSM). The central composite design (CCD) is used to determine the effect of activation temperature and activation time on some responses i.e. proximate analysis, ultimate analysis, methylene blue number, iodine number, electrical conductivity, yield percentage, and some gas pollutants adsorption. The results showed that almost all of activated charcoal met the technical standard of activated charcoal of SNI 06-3730-1995 for moisture content, ash content, volatile matter, fixed carbon, iodine number, and methylene blue number. The optimum conditions for the activation process involving the response observed were at 787.85 °C for 116.52 minutes

Lignocellulosic waste from oil palm industry is a potential versatile resource. It can be used as raw material of bio-composite, pulp and paper, bioenergy, and many chemicals products. The aimed of this research was to investigate the characteristics of particleboard from oil palm empty fruit bunch (EFB) bonded with phenol formaldehyde (PF)-fortified oil palm EFB liquid adhesive. Fortification level of EFB liquid was varied at 5, 10, and 15%. The adhesive level of 10, 15, and 20% were used for particleboard manufactures with target density of 0.7 g cm-3. The particleboard quality was evaluated based on its physical (density, moisture content, thickness swelling) and mechanical properties (modulus of elasticity, modulus of rupture, internal bonding, and screw holding resistant) according to JIS standard. In order to improve bonding quality, the EFB particles was treated by hot water at 100 oC for 6 h. The results showed that the quality of particleboard increased by addition of fortifier as well as adhesive level, except for thickness swelling. The best particleboard properties was produced with 20% adhesive level and 15% fortifier, however, physical and mechanical properties of most particleboard produced did not satisfy the JIS A 5908:2003 requirement.Keywords: empty fruit bunch, fortifier, liquid adhesive, oil palm, particleboard, phenol formaldehyde

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.
