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

The objective of this research was to evaluate the natural durability of nine Indonesia lesser known species against subterranean termite (Coptotermes curvignathus Holmgren) and dry wood termite (Cryptotermes cynocephalus Light) attacked grown in Dramaga campus, Bogor Agricultural University. Sap and hearth wood parts of mangium, durian, nangka, angsana, afrika, rukam, trembesi, bisbul, and ki sampang woods with diameter around 13-30 cm were used in this experiment. Evaluation of natural durability of wood referred to SNI 01-7207-2006. The hearth wood of nangka wood was the most durable wood against C. curvignathus attacked and it was classified into 2nd class. Bisbul, rukam and trembesi woods both sap and herath wood and heart wood of angsana wood were classified into 3rd class. Mangium and afrika woods both sap and hearth woods were classified into 4th class. Ki sampang and durian woods both sap and hearth woods and sap wood of nangka and angsana woods were classified into 5th class. All the 9 woods species (i.e. rukam, bisbul, mangium, ki sampang, afrika, nangka, durian, angsana and trembesi woods) both sap and hearth wood parts were moderately resistance to C. cynocephalus and they were classified into 3rd class.Key words: dry wood termite, hearth wood, lesser known species, natural durability, sap wood, subterranean termite

This research focused on distribution of water borne preservative on woods preserved using full cell and empty cell processes. Retention, penetration, and durability of preserved woods against dry wood termite (Cryptotermes cynochephalus LIGHT) attacked were evaluated. Pine (Pinus merkusii) and sengon (Paraserianthes falcataria) woods were preserved using 5% Wolmanit CB (water soluble preservative) using full cell and empty cell processes. The results indicated that retention of preservative preserved with full cell process was higher than empty cell process. Copper penetration on sengon wood preserved using full cell process was much higher than empty cell process. Distribution of copper and chromium on wood preserved using full cell process evenly distributed through the wood both in pine and sengon woods. They were sharply decreased from outerpart to inner part of wood when preserved using empty cell process. The whole part of pine and sengon woods preserved by either full cell or empty cell processes strongly resistance against dry wood termite attacked. Quantitative analysis of active substance of preservative using atomic absorption spectroscopy (AAS) could detect the preservative in preserved wood more accurately compared using conventional method (retention and penetration tests).Key words: distribution pattern, durability, empty cell process, full cell process, water borne preservative
