Abstract

Ulat kantung (Metisa plana) merupakan salah satu hama penting pada tanaman kelapa sawit menghasilkan yang dapat menyebabkan kerusakan daun dan menurunkan produktivitas tanaman. Salah satu upaya pengendalian yang dapat dilakukan adalah penggunaan insektisida berbahan aktif Asefat melalui metode injeksi batang. Penelitian ini bertujuan untuk mengetahui efektivitas insektisida Asefat dalam mengendalikan hama Metisa plana, menentukan dosis yang paling efektif, serta mengetahui pengaruh aplikasi injeksi batang terhadap penurunan populasi hama. Penelitian dilaksanakan pada tanaman kelapa sawit menghasilkan di Kelurahan Pulo Padang, Kecamatan Rantau Utara, Kabupaten Labuhanbatu. Penelitian menggunakan Rancangan Acak Kelompok (RAK) non-faktorial dengan lima perlakuan, yaitu P0 (kontrol), P1 (Asefat 10 mL/pokok), P2 (Asefat 20 mL/pokok), P3 (Asefat 30 mL/pokok), dan P4 (Asefat 40 mL/pokok), dengan enam ulangan sehingga diperoleh 30 satuan percobaan. Pengamatan dilakukan sebelum aplikasi (H-1) dan setelah aplikasi pada H+3, H+7, H+14, dan H+21. Parameter yang diamati meliputi populasi ulat kantung hidup dan persentase mortalitas. Data dianalisis menggunakan ANOVA dan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf 5% apabila terdapat pengaruh nyata. Hasil penelitian menunjukkan bahwa aplikasi Asefat melalui metode injeksi batang memberikan pengaruh sangat nyata terhadap penurunan populasi Metisa plana (P<0,05). Perlakuan P4 dengan dosis 40 mL/pokok merupakan perlakuan paling efektif, dengan rata-rata populasi ulat pada H+21 sebesar 1,50 ekor per pelepah dan mortalitas mencapai 88,61%. Hasil uji DMRT menunjukkan bahwa seluruh perlakuan berbeda nyata satu sama lain. Dengan demikian, semakin tinggi dosis Asefat yang diberikan melalui metode injeksi batang, semakin tinggi efektivitas pengendalian hama ulat kantung pada tanaman kelapa sawit menghasilkan.

One method of controlling this pest is the application of an insecticide containing the active ingredient acephate through stem injection. This study aimed to determine the effectiveness of acephate insecticide in controlling Metisa plana, determine the most effective dosage, and evaluate the effect of stem injection on reducing pest populations. The study was conducted on mature oil palm plants in Pulo Padang Village, Rantau Utara District, Labuhanbatu Regency. The research used a non-factorial Randomized Complete Block Design (RCBD) consisting of five treatments: P0 (control), P1 (acephate 10 mL/plant), P2 (acephate 20 mL/plant), P3 (acephate 30 mL/plant), and P4 (acephate 40 mL/plant), with six replications, resulting in 30 experimental units. Observations were conducted before application (H-1) and after application at H+3, H+7, H+14, and H+21. The observed parameters included the number of living bagworms and mortality percentage. The data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level when significant differences were detected. The results showed that the application of acephate through stem injection had a highly significant effect on reducing the population of Metisa plana (P<0.05). Treatment P4, with a dosage of 40 mL/plant, was the most effective treatment, resulting in an average population of 1.50 bagworms per frond at H+21 and a mortality rate of 88.61%. The DMRT results showed that all treatments differed significantly from one another. Therefore, increasing the dosage of acephate applied through stem injection increased the effectiveness of bagworm control in mature oil palm plants.
