Abstract
Rice production faces various challenges, one of which is the attack of Leptocorisa oratorius. In pest management, farmers tend to rely on chemical insecticides, which leads to the development of resistance. This study aims to determine the effect of botanical insecticides derived from Pluchea indica leaf extract on the mortality of Leptocorisa oratorius in rice plants. This study was conducted from July to August 2025 at the Bioscience and Plant Protection Laboratory, Jember State Polytechnic. The experiment used a Completely Randomized Design (CRD) Non- Factorial with six treatments and four replications, consisting of a control and Pluchea indica leaf extract concentrations of 5%, 10%, 15%, 20%, and 25%. Observational data were analyzed using ANOVA, and if there was a significant effect, further analysis was carried out using the Least Significant Difference (LSD) test at a significance level of 5%. Lethal Concentration values were determined through probit analysis in SPSS based on mortality data. The results showed that botanical insecticides from Pluchea indica leaves had a significant effect on rice pest mortality in treatment P5 (25% concentration) with an LC₉₅ value of 41.78%
