Abstract Bintaro fruit contains a lot of organic compounds that cause mortality of a number of insects including cockroaches. The reasearch aims to determine the effect of various concentrations of bintaro fruit (Cerberra manghas) as bioinsecticides, and to know the effective concentration to achieve mortality from Periplaneta americana cockroaches . The method used in this study is a pure experimental method that uses Completely Randomized Design (CRD) with 5 treatments and 5 repetitions, with different concentrations namely concentrations of 0%, 10%, 20%, 30%, and 40%, so that the sum of all a sample of 125 Periplaneta americana cockroaches. Based on the results of statistical tests using the ANOVA test and Scheffe further test, the treatment of the concentration of bintaro fruit extract (Cerberra manghas) 40% significantly affected the Periplaneta americana cockroach compared with other treatments and in terms of LC50 values, is the mortality rate had reached 50% in observations 5 x 4 hours and more mortality than other concentrations.
