Smoke treatment can be used to enhance wood resistance to subterranean termite attack. In this study, kesambi (Schleichera oleosa) wood was pyrolyzed to produce charcoal. The smoke produced as a by-product of pyrolysis was used to treat sengon (Falcataria moluccana), jabon (Anthocephalus cadamba), mangium (Acacia mangium), and pine (Pinus merkusii) wood samples for 1, 2, or 3 weeks. Following the smoke treatment, the wood specimens were exposed to subterranean termites (Coptotermes curvignathus Holmgren) according to the Indonesian standard 7207-2014 in a laboratory. The color change caused by smoke treatment was observed, and chemical analysis of smoke was also done. The results showed that chemical compounds of kesambi smoke predominantly consisted of acetic acid, phenol, ketones, amines, and benzene. The color of smoked wood became darker, less yellow, and a little redder, while a longer smoking period produced a darker color which was more resistant to termite attack. Smoke treatment enhanced the resistance of wood to subterranean termite attack, and the resistance levels were not significantly different based on the duration of the smoke treatment.

kesambi（Schleichera oleosa ）烟处理的快速生长的热带木材的颜色变化和抗白蚁作用。

烟雾处理可用于增强木材抵抗地下白蚁侵袭的能力。在这项研究中，将kesambi（Schleichera oleosa）木材热解生成木炭。热解副产物产生的烟气用于处理sengon（Falcataria moluccana），jabon（Anthocephalus cadamba），Mgium（Acacia mangium）和松木（Pinus merkusii）木材样品1、2或3周。烟气处理后，按照印度尼西亚标准7207-2014在实验室中将木材标本暴露于地下白蚁（Coptotermes curvignathus Holmgren）。观察到由烟雾处理引起的颜色变化，并对烟雾进行了化学分析。结果表明，kesambi烟的化学成分主要由乙酸，苯酚，酮，胺和苯组成。烟熏木的颜色变深，较少的黄色，略带红色，而较长的吸烟时间会产生较深的颜色，更能抵抗白蚁的侵袭。烟熏处理增强了木材对地下白蚁侵袭的抵抗力，并且烟熏处理的持续时间对烟熏抵抗力水平没有显着差异。
