dc.description.abstract Along with the awareness to obtain quality plant products, the use of plant-based insecticides is increasingly being used. One of the plants used as a plant-based insecticide is Jatropha curcas L. (Jarak pagar) because it contains toxic ingredients to kill cabbage caterpillar pests (Crocidolomia binotalis). This study aims to determine the effectiveness of Jatropha curcas L. on the mortality of Crocidolomia binotalis cabbage caterpillars. The research method used was a Completely Randomized Design (CRD) 7 × 3, consisting of seven treatment concentrations (0,000 ppm, 10,000 ppm, 20,000 ppm, 30,000 ppm, 40,000 ppm, 50,000 ppm, 60,000 ppm), with three replications. Observations were made at 24, 48, 72, 96, 120, 144 hours after application (HAA) of Jatropha. The research activities were carried out in two stages, namely 1) the extraction stage of Jatropha curcas L. seeds and the breeding of the Crocidolomia binotalis test larvae and 2) the testing stage with seven concentration levels of Jatropha curcas L. extract as a plant-based insecticide. ANOVA test showed that the treatments of Jatropha curcas L. extract gave the death effect on larvae [F-count > F-table (116.8 > 2.37)]. Dead larvae change color to black and their body shape will curve. The fastest larval death occurs 24 HAA, with a concentration of 40,000 ppm, which is 50%. At lower concentrations (30,000 ppm), which can kill larvae up to 50%, occurs 120 HAA. With a concentration of 50,000 ppm, 90% of larvae can be killed occurring 96 HAA. en_US
