<p>Termite <em>Coptotermes</em><em> sp.</em> is one of the most harmful types of termite class of Rhinotermitidae, Coptotermes genus. One of the controlling efforts is by using an extract of <em>Carica</em><em> papaya</em> leaves. This study aims at finding out the effectiveness of the leaf extract<em> Carica papaya</em> on the termite <em>Coptotermes</em><em> sp.</em> Mortality, as well as finding out the concentration of the extract of papaya C. leaf highly effecting on controlling the termites <em>Coptotermes sp.</em> This was an experimental research with Completely Randomized Sampling (CRS) in six extract treatments (0%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%) and 3 replications. The mortality data and the loss of feed were analyzed through the analysis of variance (ANOVA) and followed by Duncan test at 5% significance level. The lethal concentration (LC) and lethal time (LT) were analyzed by Probit analysis. The results showed that the leaf extract of <em>Carica</em><em> papaya</em> can be used to control termites and it functions most effectively at a concentration of 1.5%. The lethal concentration (LC) leaf extract of <em>Carica</em><em> papaya</em> is 0.005 and lethal time (LT) is 3.201 days.</p><p> </p><p>Key words: <em>Coptotermes sp</em>., extract of <em>Carica</em><em> papaya</em> leaves</p>
