Abstract

This study aimed to analyze the effectiveness of the smoking method using teak (Tectona grandis) wood waste in the agathis (Agathis sp) wood preservation process. The smoking process was done by putting teak wood waste into the combustion chamber and inserting agathis wood into the smoke room. The smoking duration was divided into 6 hours, 9 hours, and 12 hours with a maximum temperature ±70°C. The analysis carried out was an analysis of the chemical compound using GC-MS pyrolysis and testing the termite based on SNI 7207-2014. The results of GC-MS showed that the resin wood treated with smoking contained anti-termite compounds, namely phenolic, phenyl, and acid compounds, with the highest composition of 92.76% obtained from the duration of 12 hours of smoking. The termite test results showed that untreated wood had a higher weight loss and lower termite mortality than smoked wood. Meanwhile, the longer the smoking process, the lower the wood weight loss with the same mortality rate of 100%. It can be concluded that the smoking method using teak wood effectively increases the durability value of agathis against termites Coptotermes curvignathus.

Abstract

Plantation forests is generally harvested at the age of less than 10 years, thus the log is in small diameter, inferior physicalmechanical properties, and susceptible to bio-deterioration. The application of glued-laminated timber (glulam) could overcome theseissues and increase its utilization. This paper reviews the utilization of wood from plantation forest for glulam. Currently, woodfrom plantations forest studied in glulam research were jabon (Anthocephalus cadamba), rubber-wood (Hevea brasiliensis),mahogany (Swietenia sp.), mangium (Acacia mangium), manii (Maesopsis eminii), mindi (Melia azedarach), pine(Pinus merkusii), sengon (Falcataria moluccana), and sungkai (Peronema canescens). Kempas wood (Koompassiamalaccensis) and merbau (Intsia sp.) from natural forests were used as a layer combination of the glulam. The adhesives usedfor manufacturing glulam were tannin-based adhesives from mangium, mahogany, and merbau, as well as synthetic adhesives,namely isocyanate and phenol resorcinol formaldehyde (PRF). The results shows that glulam bonded with tannin-based adhesivehas physical-mechanical properties comparable with those of solid wood and glulam adhered with PRF adhesive. The physicalmechanical properties of glulam glued with isocyanate were similar with its solid wood. However, the shear strength of glulam waslower than solid wood. There was no delamination occurred in both cold and boiling water delamination tests. Thus, it fulfilledJAS 1152- 2007. The polystyrene impregnation applied in sengon and mindi glulams manufacturing resulted in a few effect ofcolor change, comparable shear strength to its solid wood, and increases its resistance to subterranean termites (Coptotermescurvignathus Holmgren) attack.
