Penelitian ini bertujuan mengetahui efektifitas pestisida nabati terhadap hama wereng batang coklat (Nilaparvata lugens Stall) pada tanaman padi sawah varietas ciherang. Penelitian ini di laksanakan di Laboratorium Kultur Jaringan dan Green House Jurusan Agroteknologi Fakultas Pertanian Universitas Negeri Gorontalo pada Bulan Maret sampai Mei 2018. Penelitian ini menggunakan rancangan acak lengkap (RAL) terdiri dari satu faktor yaitu: Konsentrasi pestisida nabati 0, 20, dan 30%, dan jenis pestisida nabati daun bintaro, daun gulma siam, dan biji mahoni. Parameter yang diamati adalah mortalitas dan perkembangan wereng batang coklat (Nilaparvata lugens Stall) setelah di aplikasi dengan pestisida nabati. Analisis data menggunakan sidik ragam (ANOVA) dengan uji DMRT 5%. Hasil penelitian menunjukan bahwa perlakuan pestisida nabati ekstrak daun Bintaro konsentrasi 30% selama 11 hari setelah aplikasi efektif meningkatkan mortalitas hama wereng batang coklat (Nilaparvata lugens Stall) sebesar 100% dibanding control sebesar 16,67%. Ekstrak biji mahoni konsentrasi 30% efektif menghambat perkembangan hama wereng batang coklat (Nilaparvata lugens Stall) dengan jumlah total telur 13 butir telur dan turunan F1 10 ekor, dibanding kontrol 42 butir telur dan turunan F141 ekor.
Kata Kunci: pestisida nabati,wereng batang coklat, bintaro, mahoni, gulma siam
ABSTRACT
The research aimed to know the effectiveness of biological pesticide on brown plant hopper (Nilaparvata lugens Stall) pest in rice field paddy of ciherang variety. It was counducted in Laboratory of Tissue Culture and Green House of Departemen of Agrotechnology, Faculty of Agriculture, State University of Gorontalo from March to Mei 2018. It applied completely randomized design comprised one factor namely concentration of biological pesticide for 0, 20, and 30%, and it's types were bintaro leaves, siam weed leaves, and mahogany grain. The observed parameters were mortality and development of brown plant hopper (Nilaparvata lugens Stall) after aplication of the biological pesticides. The data analysis employed Analysis of Variance (ANOVA) with DMRT test for 5%. The research finding confirmed that treatment of Bintaro leave extracts as the biological pesticide in 30% concentration during 11 days after the application was effective to improve mortality of brown plant hopper (Nilaparvata lugens Stall) for 100% compared to control for 16,67%. Extract of mahogany grain in 30% concentration was found effective in hampering the development of brown plant hopper (Nilaparvata lugens Stall) with egg total of 13 eggs and F1 derivative of 10 insects compared to control 42 eggs and F1 derivative of 41 insects.
Keywords: biological pesticide, brown plant hopper, bintaro, mahogany, siam weed
