Abstract

Damages of building construction due to termite attacks have caused high economic losses and therefore, efforts are continuously developed to overcome the serious problem. Baiting system is one way to control termite attacks as it consists of acceptable termite food sources, combined with a slow-acting substance lethal to termites. This study was conducted to produce termite bait materials from organic waste mixtures and evaluate its effectiveness against termite attacks in the field. The termite baits were produced by mixing paper, cardboard, and degraded pine wood, combined with leaves of Melaleuca leucadendron Linn assumed to be toxic to termites. Tapioca starch was used as glue and added to the organic materials mixture before pressed at room temperature with the target density of 1.0 g/cm3. The produced baits were placed in the field with signs of heavy attacks of termites, Coptotermes sp., and observed every three days for the termite elimination. Results showed that the bait formulation enables to significantly eliminate the termite attacks with high attractant properties. However, its effectiveness was still lower than the commercial bait due to its high capacity of water absorption, indicating the importance of further research on its mixture and glue formulation.

Abstract

Information about colony fragments survival of the termite species Coptotermes curvignathus Holmgren in the laboratory is very limited. This study was conducted to determine colony fragments survival of the subterranean termite C. curvignathus Holmgren in laboratory maintenance. The test media used the Termitarium PSIH-IPB: 1999 as a glass vessel containing 4 kg of a mixture of sand and clay with 4 proportions and 4 different pH determined as treatments that would be studied for their effects on termite survival. The results showed that the proportion of the sand:clay mixture affected the survival and feeding preferences of the subterranean termite C. curvignathus Holmgren. The highest percentage of termites that survived was found in the termitarium containing a mixture of sand:clay 50:50. The highest percentage of bait wood weight loss occurred in the test media containing a mixture of sand: clay 50:50. The weight loss of bait wood is directly proportional to the termites survival.

Abstract

Fast-growing species are chemically and thermally modified to improve quality. These changes affect wood’s chemical composition and surface characteristics. This study aims to analyze the durability of fast-growing teak wood that has been chemically and thermally modified. Chemical modification was carried out by impregnation using citric acid and polyethylene glycol (PEG) 400, while heat modification carried out at 150 °C. The wettability of wood was tested by measuring the contact angle with six types of liquid, aquades, toluene, glycerin, methanol, alkyd, and acrylic paint. The results showed that chemical modification treatment significantly improved the wettability of wood compared to control and heat treatment. Wood treated with citric acid and PEG 400 exhibits a lower contact angle, indicating increased liquid absorbency. Conversely, heat treatment increased the contact angle value making the wood more hydrophobic. Alkyd showed better wettability than acrylic paints, possibly due to their lower viscosity values. This suggests that chemical modification more effectively improves wood coating adhesion.

Abstract

The wood processing industry produces red meranti (Shorea leprosula) sawdust waste. This waste is generally not optimally utilized and can have negative impact. The use of sawdust as a raw material for particleboard is an environmentally friendly and economically valuable solution, given that particleboard has the potential to replace solid wood in the wood industry. This study aims to utilize red meranti sawdust waste as raw material for particleboard production using urea formaldehyde adhesive with different particleboard thicknesses. This studi evaluates the effect of thickness variations (1 cm, 1.5 cm, and 2 cm) on the physical properties (moisture content, density, and thickness swelling) and mechanical properties (elasticity/MoE, breaking strength/MoR, and tensile strenth) of particleboard. The results of testing the physical properties of particleboards showed that the average moisture content ranged from 10.92 % to 11.76 %, the density ranged from 0.54 g/cm3 to 0.6 g/cm3, and the thickness swelling ranged from 4.05 % to 12.02 %. Mechanical property testing of particleboard showed that the average MoE ranged from 9,110 kg/cm2 to 67,813 kg/cm2, MoR ranged from 9.44 kg/cm2 to 37.93 kg/cm2, and internal bonding ranged from 0.292 kg/cm2 to 0.396 kg/cm2. Based on the results of statistical analysis, it shows that in testing physical properties, thickness variation does not affect moisture content and density, but affects the thickness swelling of particleboards after being immersed for 2 and 24 hours. In mechanical property testing, thickness variation did not affect internal bonding, but it did affect MoE and MoR. Overall, this study confirms the potential of red meranti sawdust waste as a raw material for particleboard, although improvements are needed in increasing mechanical strength, particularly MoR and internal bonding.
