Abstract

Coptotermes curvignathus Holmgren is one of the building pests that have the highest level of damage in Indonesia (Subekti, 2016). This termite control still uses synthetic termiticide. This synthetic termiticide is carcinogenic if exposed to human skin, not on target and causes soil pollution. Therefore, natural termiticide is needed. Alternative natural materials that can be used as natural termiticide is gaharu leaf Aquilaria malaccensi. Research method that used in this study are made extract of gaharu leaf using Soxhlet method, nanoparticle fabricaton of gaharu leaf and eating preferences of subterranean termites Coptotermes curvignathus Holmgren (Ohmura et al. 2000). Result research demonstrate that main compounds nanoparticle from gaharu leaf were n-hexane, methanol and ethyl acetate fractions. The ANOVA and Tukey’s test results showed that termite mortality was significantly higher with the extract treatment compared to the negative control (F= 3.116, df1,2= 17, 36; P< 0.005). The LC50 value of n-hexane nanoparticles against C. curvignathus was lower (0.11%) than ethyl acetate nanoparticles (0.88%) and methanol extract (5.88%). The conclusion of this research is the extract of gaharu leaf was effective as a natural biotermiticide that is environmentally friendly, right on target and nonpolluting.
