Abstract: Kerusakan daun oleh ulat grayak (Spodoptera litura) mengganggu proses fotosintesis dan akhirnya mengakibatkan kehilangan hasil panen. Kerusakan daun sebesar 12,5%, menyebabkan kerugian ekonomi setara dengan biaya dua kali aplikasi insektisida. Tujuan penelitian ini untuk mengetahui efektivitas berbagai sumber pestisida nabati terhadap hama S. litura dan mengetahui efektivitas berbagai pestisida nabati terhadap produksi pada tanaman kacang kedelai (Glycine max L. Merill). Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) non faktorial yang terdiri dari 1 faktor, yaitu : 1. Perlakuan berbagai pestisida nabati terdiri dari : P0(-) = air (kontrol), P0(+) = pestisida kimia merk dagang Fostin (bahan aktif Klorpirifos 550 g/l : sipermentrin 60 g/l), P1 = ekstrak biji jarak pagar konsentrasi 15% P2 = ekstrak biji jarak pagar konsentrasi 30%, P3 = ekstrak biji jarak pagar konsentrasi 45%. P4 = ekstrak daun serai wangi konsentrasi 15%, P5 = ekstrak daun serai wangi konsentrasi 30%, P6 = ekstrak daun serai wangi konsentrasi 45%, P7 = ekstrak daun babadotan konsentrasi 15%, P8 = ekstrak daun babadotan konsentrasi 30%, P9 = ekstrak daun babadotan konsentrasi 45%. Hasil penelitian memperlihatkan pemberian insektisida nabati tidak berpengaruh nyata dalam mengendalikan hama S. litura. Pestisida nabati dari daun babandotan konsentrasi 45% merupakan perlakuan yang terbaik dalam mengendalikan hama S. litura dengan persentase mortalitas mencapai 67% dibandingkan dengan perlakuan pestisida nabati lain yang diuji. Efektivitas dari pestisida nabati yang tertinggi terdapat pada perlakuan P9 dengan nilai 103,03% sedangkan yang terendah P1, P2, dan P7 dengan nilai 21,21% Pemberian insektisida nabati tidak berpengaruh nyata dalam produksi tanaman kacang kedelai. Pestisida nabati dari daun babandotan konsentrasi 45% memiliki produksi tertinggi sebesar 215,33 g atau 1,49 ton/ha, dibandingkan dengan perlakuan pestisida nabati lain yang diuji. Leaf damage by armyworm (Spodoptera litura) disrupts the process of photosynthesis and eventually results in crop loss. Leaf damage is 12.5%, causing an economic loss equivalent to the cost of twice the insecticide application. The purpose of this study was to determine the effectiveness of various sources of botanical pesticides against S. litura pests and to determine the effectiveness of various botanical pesticides on soybean production (Glycine max L. Merill). This research was conducted using a non-factorial Randomized Block Design (RBD) consisting of 1 factor, namely: 1. Treatment of various vegetable pesticides consisting of: P0(-) = water (control), P0(+) = chemical pesticides trademark Fostin (Active ingredient Chlorpyrifos 550 g/l : cypermentrin 60 g/l), P1 = Jatropha seed extract concentration 15% P2 = Jatropha seed extract concentration 30%, P3 = Jatropha seed extract concentration 45%. P4 = 15% concentration of citronella leaf extract, P5 = 30% concentration of citronella leaf extract, P6 = 45% concentration of citronella leaf extract, P7 = 15% concentration of babadotan leaf extract, P8 = 30% concentration of babadotan leaf extract, P9 = babadotan leaf extract concentration of 45%. The results showed that the application of vegetable insecticides had no effect on controlling S. litura pests. Botanical pesticides from babandotan leaves with a concentration of 45% were the best treatments for controlling S. litura pests with a mortality rate of 67% compared to the other tested pesticides. The effectiveness of the highest botanical pesticides was in the P9 treatment with a value of 103.03% while the lowest were P1, P2, and P7 with a value of 21.21%. The application of vegetable insecticides had no effect on soybean crop production. Botanical pesticides from babandotan leaves with a concentration of 45% had the highest production of 215.33 g or 1.49 tons/ha, compared to the other vegetable pesticides tested.
