The results of laboratory test of wood-wool board properties made fram ten wood species obtained from Nusa Tenggara province are reported in this paper. The properties tested were board density, moisture content, thickness reduction due Io compression and benJing strengih.The Study revealed that the average yield of wood-wool was 423,6 kg per cubic meter of log input. The wood-wool of Anthoceplus cadamba Miq. and Anthocephallus sp. must be soaked in cold water for 24 houn prior to manufacturing of wood-wool board, whereas she other species did not require soaking. The physical and mechanical properties of wood-wool board from nine wood species mineralized with CaCl2 solution were in conformity with the DIN 1101 standard. However, only three wood species mineralized with Ca (OH)2 suspension met the standard requirement.

The results of a study on the properties of wood-wool board made from tapped and untapped pine (Pinus merkusii Jungh et de Vriese) is reported in this paper. The wood is obtained from West Java.The result shows that hydration temperature of tapped tree is 36oC, and untapped pine is 43°C. Based on this data, wood from tapped pine tree can be classified as medium and that from untapped pine as good for wood-wool board material. In general the wood-wool board properties of both wood sources meet DIN standard. The effect of tapping, cement proportion, kind of catalyst, and interaction between cement proportion and kind of catalyst on the mechanical properties of wood-wool board are significant. Tapped pine is better than untapped pine as raw material for wood-wool board.

Papan semen skala laboratorium dibuat dari serutan kayu sengon (Paraserianthes falcataria (L) Nielsen) dengan perbandingan berat antara kayu dan semen 1: 2, 5. Magnesium khlorida (MgCI2) dan natrium silikat (Na2SIO3) digunakan sebagai katalisator. Banyaknya MgCI2atau Na2SIO3 yang ditambahkan pada saat pembuatan papan semen adalah 0: 2.5: 5; 7,5 dan JO % dari berat semen.Kerapatan rata-rata papan semen yang dibuat adalah 1,17 g/cm3. Macam dan banyaknya katalisator berpengaruh nyata pada sifat fisis dan mekanis papan semen kecuali pada sifat pengembangan linier. Penambahan MgCI2 terutama 5% memperbaiki sifat papan semen, tetapi tidak ada pengaruh yang nyata pada perlakuan lain. Modulus patah papan semen yang dibuat dengan katalisator MgCI2 (118-133 kg/cm2) memenuhi persyaratan BISON dan ISO (90-150 kg/cm2). Keteguhan rekat internal dan papan semen tersebut lebih baik dari pada papan semen yang dibuat dengan katalisator Na2SIO3. Berdasarkan hasil penelitian ini, disarankan untuk menambahkan MgCI2 sebanyak 5 % dari berat semen dalam pembuatan papan semen.

This study investigated the resistance of three-layer laminated bamboo boards (LBB’s) to subterranean termites (Coptotermes curvignathus Holmgren) according to the Indonesian standard (SNI 01.7207-2006). Bamboo strips for LBB fabrication were prepared from Gigantochloa pseudoarundinacea and assigned into 4 groups by pre-treatment methods namely: untreated, cold soaking in 5% boron solution for 2 hours, bleached by 17.5% and 20% hydrogen peroxide solutions. The LBB was formed by tannin resorcinol formaldehyde (TRF). Wheat flour was used as extender with two different concentrations (i.e., 2.5% and 5%) based on TRF weight. The results indicated that the resistances of LBB’s were much affected by pre-treatment methods. Applying different concentration of extender in TRF resin resulted in similar termite resistance of LBB’s against C. curvignathus Holmgren. Pre-treated of bamboo strips with 5% boron solution and bleached by 17.5% and 20% hydrogen peroxide solutions prior to be LBB manufactured improved the termite reistance of LBB’s against C. curvignathus Holmgren one level compared to untreated LBB. The termite-resistance of LBB made from untreated bamboo strips was categorized as class IV (poor) whereas those from boron- or hydrogen peroxide-treated bamboo strips belonged to class III (moderate).Key words: boron solution, hydrogen peroxide, laminated bamboo board, subterranean termite, tannin resorcinol formaldehyde

The objective of this study were to determine the characteristics of laminated bamboo lumber (LBL) glued with tannin resorcinol formaldehyde with particular focus on the effects of varying pre-treatment of bamboo strips and extender content on the properties of LBL. Bamboo strips for LBL fabrication were prepared from mature culms of andong bamboo (Gigantochloa pseudoarundinaceae). The strips were assigned into 4 groups by pre-treatment methods: untreated, cold soaking in 5% boron solution for 2 hours, bleached with 17.5% H2O2 solution, and bleached with 20% H2O2 solution. The LBL was manufactured using tannin resorcinol formaldehyde (TRF) added with extender at 4 levels equal to 0, 2.5, 5, and 10% of TRF. The cold pressing time applied was 4 hours. The results showed that the average density, moisture content, thickness swelling, bending strength and bonding strength of LBL produced were 0.77 g cm-3, 8.9%, 5.2%, 1146 kg cm-2, and 51.5 kg cm-2 respectively. No delamination occurred in all samples which indicating high bonding quality. There was strong interaction between pre-treatment of bamboo strips and extender content in affecting some properties of LBL. In general three-layer thick LBL glued with tannin resorcinol formaldehyde adhesive had strength values similar to wood strength class I. Laminated bamboo lumber is suitable for wood substitute especially for furniture material.Key words: extender, laminated bamboo lumber, pre-treatment, tannin resorcinol formaldehyde

The response of Gigantochloa pseudoarundinacea to isocyanate adhesive was investigated by evaluating its bonding quality. The bamboo strips were categorized based on the position at the bamboo culm viz bottom,midle, and top. One part of the bamboo strips were immersed in 7% boron solution for 2 hours.The treated and untreated bamboo strips were glued parallel to each other using the isocyanate adhesive at the glue spread of 250 g m-2 to produce two-ply laminates. The bonding surfaces of two-ply laminates were designed into 3 different combinations viz between inner and outer surfaces, both between inner surfaces, and both between outer surfaces. The bonding strength and bamboo failure were evaluated in dry and wet conditions. Results showed that the response of G. pseudoarundinacea to isocyanate adhesive was significantly affected by the posision at the bamboo culm, bamboo strips treatment and combination of bonding surfaces. In comparasion with the middle and the top part, the bottom part of bamboo culm had the highest bonding strength (dry test). However, the wet test results showed that the bonding strength of laminates made from bottom part did not significantly different with that of middle part. The preservation treatment on bamboo strips reduced the bonding strength.Key words: bamboo, bonding strength, isocyanate, laminates, preservation

Rattan in Indonesia is traditionally utilized for furniture, binding materials, household appliances, and handicraft items. Small diameter rattans are commonly used by craftsmen, while large diameter rattans are not optimally utilized. Large diameter rattan, however, has potential to be developed into rattan laminated board (RLB) by gluing rattan strips using appropriate adhesive. Nevertheless, the information of the suitable natural adhesive for RLB production is still limited. Laboratory scale of RLBs with the dimensions of 60 cm x 7.5 cm x 1.5 cm were manufactured using batang rattan strips (Calamus zollingeri Becc.). The strips were glued with six types of adhesives (4 types of natural adhesives and 2 types of commercial synthetic adhesives) and three glue spread rates of (100, 150, and 200 g/m2) were used. The study objective was to determine the effect of rattan pre-treatments, adhesive types and glue spread rates on the bonding quality and formaldehyde emission of RLBs. The results showed that batang rattan can be processed into RLBs by using natural adhesives originating from wood bark extract (mangium, mahogany), merbau wood powder, as well as commercial synthetic adhesives such as isocyanate and polyurethane. The appropriate pre-treatment in producing RLBs for interior furniture was by applying oil heat treatment with kerosene solution (80 kerosene : 20 water) and glued with tannin adhesive of mangium bark extract with glue spread of 200 g/m2. Similarly, rattan strips treated with heated oil (80 kerosene : 20 water) and glued with polyurethane adhesive (glue spread of 200 g/m2) produced excellent RLBs for exterior furniture.
