Abstract

Serangan hama ulat api (Setothosea asigna) pada tanaman kelapa sawit menyebabkan kerusakan daun yang mengganggu proses fotosintesis, sehingga diperlukan tindakan pengendalian yang efektif melalui aplikasi fogging berbahan aktif sipermetrin. Penelitian ini bertujuan mengetahui perubahan populasi dan tingkat efektivitas pengendalian hama ulat api sebelum dan sesudah aplikasi fogging. Objek penelitian adalah tanaman kelapa sawit menghasilkan berumur 6 9 tahun dengan tinggi tajuk 8–11 meter pada lima blok pengamatan, yaitu B5, B7, B10, B11, dan C11 di PT Herfinta Afdeling 1. Penelitian menggunakan metode kuantitatif deskriptif dengan pendekatan evaluatif, melalui sensus populasi ulat api per pelepah sebelum dan sesudah fogging, kemudian dianalisis menggunakan uji normalitas Shapiro-Wilk dan Paired Sample t-test pada taraf nyata α = 0,05. Hasil penelitian menunjukkan rata-rata populasi ulat api menurun dari 0,94 menjadi 0,29 ulat per pelepah, dengan nilai signifikansi 0,000 (p<0,05) yang menunjukkan perbedaan nyata antara sebelum dan sesudah aplikasi. Tingkat efektivitas fogging rata-rata sebesar 69,32% dan termasuk kategori efektif, dengan efektivitas tertinggi pada blok B10 (77,42%) dan terendah pada blok B5 (55,21%). Disimpulkan bahwa fogging efektif menekan populasi ulat api dan disarankan dipadukan dengan monitoring rutin serta prinsip Pengendalian Hama Terpadu agar pengendalian lebih optimal dan risiko resistensi insektisida dapat diminimalkan.

This study aimed to determine the change in pest population and the effectiveness of fogging before and after application. The research object was mature oil palm aged 6–9 years with canopy heights of 8–11 meters across five observation blocks, namely B5, B7, B10, B11, and C11 at PT Herfinta Afdeling 1. The study used a descriptive quantitative method with an evaluative approach, through a census of caterpillar population per frond before and after fogging, analyzed using the Shapiro-Wilk normality test and Paired Sample t-test at a significance level of α = 0.05. Results showed the average population decreased from 0.94 to 0.29 caterpillars per frond, with a significance value of 0.000 (p<0.05), indicating a real difference before and after application. The average fogging effectiveness was 69.32%, classified as effective, with the highest effectiveness in block B10 (77.42%) and the lowest in block B5 (55.21%). It is concluded that fogging effectively suppresses the caterpillar population and should be combined with routine monitoring and Integrated Pest Management principles to optimize control and minimize the risk of insecticide resistance.
