Brown planthopper (Nilaparvata lugens) is a very dangerous pest for rice plants which has become a global pest. One of the efforts to eradicate brown planthopper pests is to use vegetable pesticides. Ciplukan leaves are thought to have an effect as a vegetable pesticide against brown planthoppers (Nilaparvata lugens) because they are considered to have alkaloid compounds and abatement substances where these substances are able to kill pests and insects. This study aims to determine the effect of ciplukan leaf extract (Physalis angulata L.) on the death of brown planthopper (Nilaparvata lugens) so that it can provide information to the public that ciplukan leaf can be used as a vegetable pesticide. This study is an experimental study with a completely randomized design (CRD) with 5 treatments and 5 replications. The samples used were brown planthopper (Nilaparvata lugens) with P0 Dichloro Diphenyl Trichloroethane (DDT) (100 ml), P1 (10%), P2 (20%), P3 (30%), and P4 (40%). Observations of dead pests were carried out for 24 hours and 48 hours. The results showed that within 24 hours at a concentration of 10% the average dead pests reached 32%, a concentration of 20% reached 48%, a concentration of 30% reached 64%, a concentration of 40% reached 80%, while within 48 hours at a concentration of the average 10% of dead pests reached 48%, the concentration of 20% reached 68%, the concentration of 30% reached 88% and the concentration of 40% reached 100%. Based on analysis of variance (Ansira) showed that ciplukan leaf extract (Physalis angulata L.) had a very significant effect (p > 0.01) on the death of brown planthopper (Nilaparvata lugens). The effective concentration to kill the brown leafhopper (Nilaparvata lugens) was 30% concentration. Key words: Ciplukan leaf extract (Physalis angulata L.), vegetable pesticides, brown planthopper (Nilaparvata lugens)
