Daftar Isi:
- The presence of Leptocorisa acuta in paddy fields can decrease up to 50 percent on rice productivity. Eco-friendly pest management using organic insecticide is needed to maintain of rice production. This study aims to determine the effectiveness of the soursop leaf insecticide on the mortality of L. acuta. This study was conducted from February to April 2022 at the Teaching Farm of paddy fields of Lampung State Polytechnic. This study used a randomized block design with 8 treatments and 3 replications. The treatments tested included: k0=Control; The concentrations of soursop leaf extract: k1=5%, k2=10%, k3=15%, k4=20%, k5=25%, k6=30%, k7=35%, and k8=40%. Organic insecticides from soursop leaf extract with a concentration of 10 – 40% were effective in L. acuta controlling. This is indicated by significant differences in the percentage of efficacy, LT50, total grain, total grain amount, empty grain, and panicle-filled grain.
- Keberadaan walang sangit pada budidaya padi sawah dapat menyebabkan penurunan hasil produksi sampai 50%. Diperlukan metode pengendalian hama untuk mempertahankan hasil produksi yang bersifat ramah lingkungan salah satunya menggunakan insektisida organik. Tujuan penelitian mengetahui efektivitas insektisida organik daun sirsak terhadap tingkat kematian hama walang sangit. Penelitian dilaksanakan di Teaching Farm Padi Sawah Politeknik Negeri Lampung pada bulan Februari sampai April 2022. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 8 perlakuan dan 3 ulangan. Setiap plot ulangan diberikan 10 hama walang sangit dewasa untuk pengamatan di tanaman padi. Perlakuan yang diujikan antara lain: k0=Kontrol; Ekstrak daun sirsak dengan konsentrasi : k1=5%, k2=10%, k3=15%, k4=20%, k5=25%, k6=30%, k7=35%, dan k8=40%. Insektisida organik daun sirsak dengan konsentrasi 10 – 40% efektif dalam mengendalikan hama walang sangit pada padi sawah yang ditunjukkan dengan perbedaan yang nyata pada persentase efikasi, LT50, jumlah gabah total, gabah hampa, dan gabah isi permalai.
