Abstract
Corn (Zea mays) production in Indonesia has experienced fluctuations due to disturbances from the fall armyworm (Spodoptera frugiperda). The utilization of plant-based pesticides from the Babandotan and Putri Malu plants is a method to control the fall armyworm while maintaining the stability of corn production. This study aims to determine the active ingredient content and the effective concentration of Babandotan and Putri Malu extract solutions in reducing the population of S. frugiperda pests. The research was conducted from June to November 2024 at the Pest Laboratory of the TPH Protection UPT in Surabaya. The study was designed based on a Factorial Randomized Complete Design (RAL) with the first factor being the type of plant extract and the second factor being the concentration of the extract, conducted with five replications. The observation parameters included phytochemical analys, phytoconstituents screening GC-MS, anti feedant activity, attack intensity, repellent activity, mortality rates, LT50, LC50, number of pupae formed, and number of imagos formed. The results showed that extracts of Babandotan and Putri Malu, particularly at the highest concentration (1%), significantly affected mortality rates, the number of pupae formed, and the number of imagos formed. The extracts contained flavonoids, tannins, and triterpenoids, which can help control the S. frugiperda population. The results of the GC-MS screening showed that the babandotan extract contains insecticidal compounds, namely 2H-1-Benzopyran, 6,7-dimethoxy-2,2-dimethyl- (25.55%); Hexadecanoic acid, methyl ester (5.68%); and 6-Octadecenoic acid (5.08%). The mimosa extract contains 3-O-Methyl-d-glucose (65.86%), Desulphosinigrin (0.65%), 3,5,6,7,8,3',4'-Heptamethoxyflavone (1.01%), and D-Amygdalin (0.12%).
