Abstract

The productivity of green beans according to BPS North Sumatra data for 2021 from 2019 to 2021 has decreased, with an average of 2.52%. One of the causes of decreased green bean productivity is the occurrence of thrips pest attacks. One alternative that can be done to overcome thrips pests is to use plant-based pesticides. This study aims to determine the effect of applying a combination of lemongrass and kenikir vegetable pesticides on thrips on the vegetative growth of green bean plants and to determine the most effective concentration of the use of vegetable pesticides. This study used a non-factorial Randomized Block Design (RBD), namely concentrations (P0 = control; P1 = 100 ml of lemongrass and marigold extracts/L water; P2 = 200 ml of lemongrass and marigold extracts/L of water; P3 = 300 ml of lemongrass and marigold extracts and kenikir/L of water). The results showed that P3 (300 ml/L) treatment had a very significant effect on attack intensity of 14.91%, attack percentage of 25.35% and leaf area index of 0.46cm. Meanwhile, each treatment P0, P1, P2, P3 had no significant effect on plant height and leaf chlorophyll levels.

Abstract

Produktivitas kacang hijau menurut data BPS Sumatera Utara tahun 2021 sejak tahun 2019 hingga 2021 mengalami penurunan yaitu dengan rata-rata 2,52%. Penyebab menurunnya produktivitas kacang hijau salah satunya adalah terjadinya serangan hama thrips. Salah satu alternatif yang dapat dilakukan untuk mengatasai serangan hama thrips adalah menggunakan pestisida nabati. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pestisida nabati kombinasi serai dan kenikir terhadap hama thrips pada pertumbuhan vegetatif tanaman kacang hijau serta untuk mengetahui konsentrasi paling efektif dari penggunaan pestisida nabati. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) Non Faktorial, yaitu konsentrasi (P0 = kontrol ; P1 = 100 ml ekstrak serai dan kenikir/L air; P2 = 200 ml ekstrak serai dan kenikir/L air; P3 = 300 ml ekstrak serai dan kenikir/L air). Hasil penelitian menunjukkan bahwa perlakuan P3(300 ml/L) berpengaruh sangat nyata pada intensitas serangan sebesar 14,91%, persentase serangan sebesar 25,35% dan indeks luas daun sebesar 0,46cm. Adapun pada setiap perlakuan P0,P1,P2,P3 tidak berpengaruh nyata pada tinggi tanaman dan kadar klorofil daun.
