Abstract
Penelitian ini bertujuan untuk menganalisis tingkat mortalitas hama ulat kantong (Metisa plana) serta mengevaluasi efektivitas pengendalian menggunakan insektisida asefat 75% melalui metode injeksi batang pada tanaman kelapa sawit TM 7 di PT. Umada Kebun Pernantian. Penelitian dilaksanakan di Blok 22 dengan luas areal 12,17 ha menggunakan 30 sampel tanaman yang mewakili 1.740 pokok. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan pre-experimental menggunakan desain one group pretest–posttest. Pengumpulan data dilakukan melalui sensus awal dan pengamatan mingguan selama tiga minggu setelah perlakuan. Hasil penelitian menunjukkan bahwa populasi awal ulat kantong sebanyak 269 ekor dengan rata-rata 8,96 ekor per pokok yang tergolong serangan sedang hingga berat. Setelah dilakukan perlakuan, populasi ulat mengalami penurunan secara bertahap menjadi 181 ekor pada minggu pertama, 105 ekor pada minggu kedua, dan 42 ekor pada minggu ketiga. Tingkat mortalitas yang diperoleh berturut-turut sebesar 32,71%, 41,99%, dan 60%, dengan total mortalitas mencapai 84,39%. Hasil uji statistik Paired Sample T-Test menunjukkan nilai signifikansi sebesar 0,000 lebih kecil dari α = 0,05 (dua sisi), sehingga dapat disimpulkan bahwa metode injeksi batang menggunakan asefat 75% efektif dalam menekan populasi hama ulat kantong pada tanaman kelapa sawit. Kata kunci: Metisa Plana, Mortalitas, Asefat 75%, Injeksi Batang, Kelapa Sawit ================================================================================================ This study aims to analyze the mortality rate of bagworm pests (Metisa plana) and evaluate the effectiveness of control using 75% acephate insecticide via the stem injection method on TM 7 oil palm plants at PT. Umada Taman Pernantian. The research was carried out in Block 22 with an area of 12.17 ha using 30 plant samples representing 1,740 trees. The research method used is quantitative descriptive with a pre-experimental approach using a one group pretest–posttest design. Data collection was carried out through an initial census and weekly observations for three weeks after treatment. The research results showed that the initial population of bagworms was 269 individuals with an average of 8.96 individuals per tree, which was classified as a moderate to heavy attack. After treatment, the caterpillar population decreased gradually to 181 individuals in the first week, 105 individuals in the second week, and 42 individuals in the third week. The mortality rates obtained were 32.71%, 41.99% and 60% respectively, with total mortality reaching 84.39%. The results of the Paired Sample T-Test statistical test show a significance value of 0.000 which is smaller than α = 0.05 (two-sided), so it can be concluded that the stem injection method using 75% acephate is effective in suppressing bagworm pest populations on oil palm plants.
