Tuba ( Derris elliptica ) is one of the insecticide-producing plant which can reduce the pest population due to its active compound, rotenone (C 23 H 22 0 6 ). The rotenone is deposit in all parts of tuba plant, as such as roots, stems, and leaves. The aim of this research aims was to evaluate the effectiveness of tuba bark extract against subterranean termite Coptotermes sp. The powder of tuba bark extract with 40-60 mesh size macerated with the ethanol by solvent obtains the extract. The extract was made into varions concentration namely 0,5%, 1%, and 1,5%, and applied to the paper disc. There are two types of termite test in this study, namely toxicity test and respiratory test. The mortality of termite and the weight loss of the paper disc were used as indicators of extract activity. The result showed that the concentration of 1,5% indicated the highest mortality from both of two types of test. This study was similar for the lowest weight loss of sample which was also given by concentration 1,5%.
