This paper discusses a study on the treatability and durability of six wood species treated by CKB preservative by full cell process against subterranean termite and powder post beetle. Six wood species measuring 5 cm by 5 cm by 60 cm were treated with 7% CKB preservative by full cell process for 1 hour, 2 hours and 4 hours in 150 psi. The treated and untreated wood samples were tested against subterranean termite and powder posts beetle for 8 months. The results of the study indicated that full cell process with CKB were able to prevent insect attack. Untreated woods specimens were susceptible to subterranean termite and powder post beetle attack. The results, after taking both retention and penetration showed that sengon (Paraserianthes falcataria (L.) Nielsen) were permeable; while cempaka (Elmerillia ovalis Dandy), surian (Toona sureni Merr.) and durian (Durio zibethinus Merr.) were moderately resistant. While mersawa (Anisoptera costata Korth.) and Palado (Aglaia sp.) were extremely resistant

The bait formulation from the mixture of organic wastes for termite (Coptotermes sp) control was evaluated in laboratory and field tests. Four formulations were prepared by equally mixing based on dried weights, i.e. the mixture of degraded pine wood and HVS wastepaper, degraded pine wood with HVS and newsprint wastepaper, degraded pine wood with HVS and cardboard wastepaper, and the mixture of degraded pine wood with HVS, newsprint, and cardboard wastepaper. Boiled soybean water was used as an additional substance of the formulation. The termite survival rate and food transfer were evaluated using no-choice test. The food transfer was studied using test samples dyed with 0.1% Nile Blue A. The food formulations were also subjected to field test for six weeks to evaluate the termite attacks. The results showed that the highest food transfer efficiency was found for degraded pine wood and HVS wastepaper formulation, however, the survival rate was not significantly different among the formulations. The field test proved that the mixture formulation of degraded pine wood with HVS and cardboard wastepaper as well as that of degraded pine wood with HVS, newsprint, and cardboard wastepaper were attacked by termites to the failure level.Keywords: bait formulation, Coptotermes sp., food transfer efficiency, survival rate, termite control

Utilization of Oil Sludge (OS) is facing until now many problems due to heavy metal content. This experiment tried to find out an alternative how to use of OS as a lignocellulosic fiber reinforced composite material. One important reason for this purpose is the wide utilization of composite material for building material. Two problems have to be solved are how to catch the heavy metal and how to increase the bonding ability of OS. In this experiment additive PTA08 was used for catching the heavy metal. The OS with additive PTA were mixed at temperature of 80ºC and fiber in varying composition (40, 50 and 60 % based oven dry weight of raw material). After mat forming, the material was pressed at temperature of 120ºC for 20 minutes. The density of composite was arranged from 0.5, 0.6 and 0.7 g/cm3. Two percent of phenol formaldehyde resin was used to increase the bonding ability of composite material. The experiment results showed that in general the OS could be used as raw material for production of composite material with medium strength. Modulus of rupture (MOR) could reach 75~120 kg/cm2, while modulus of elasticity (MOE) 5000~7000 kg/cm2. Water absorption of the product was excellent namely below 20 %, and the thickness swelling varied from 8 to 18 %. The leaching test results showed that the leaching of heavy metal was fulfilled the standard

This study was to investigate the changes of morphological, macroscopic and microscopic characteristic on betung bamboo fiber during single culture of white rot fungi pretreatment. Fresh, and bark less 2 years old betung bamboo (Dendrocalamus asper) chips, 1.6 cm in length were inoculated by 10% of white-rot fungi inoculums stock for 30 and 45 days in room temperature. This study used three kinds of fungi i.e Trametes versicolor, Pleurotus ostreatus and Phanerochaete chrysosporium. After the incubation period was finished the chips were separated by maceration process (Schutze method) to analyze the fiber dimension and its derived value. The fibers were then observed the macroscopic and microscopic structure by optical microscope. The pretreatment caused the decreasing of fiber length, cell wall thicknesses, while the lumen and fiber diameter were since in versa. The improvement on fiber derived value except muhlsteph ratio was found in this study. Bamboo pretreated by T. versicolor for 30 days showed the best fiber dimension and fiber derived value and the treated bamboos were predicted to produce pulp with superior grade quality (grade I).Key words: bamboo structure, betung bamboo, fiber dimension, white rot fungi
