| Abstract: | Penelitian ini berjudul Sebaran dan Intensitas Serangan Hama Ulat Kantong Metisa plana pada Tanaman Kelapa Sawit (Elaeis guineensis) Jacq di PT Perkebunan Nusantara IV Dolok Ilir Regional II. Penelitian ini bertujuan untuk mengidentifikasi tingkat serangan hama ulat kantong serta menganalisis intensitas serangan (IS) pada beberapa blok pengamatan di Afdeling IV dan Afdeling V. Pengamatan dilakukan secara langsung selama empat minggu pada bulan Juli– September 2025. Data yang diperoleh dianalisis secara deskriptif untuk mengetahui kategori tingkat serangan pada masing-masing blok. Hasil penelitian menunjukkan bahwa serangan hama ulat kantong ditandai dengan gejala kerusakan berupa bercak kecokelatan hingga kehitaman pada helaian daun yang berpotensi mengurangi luas permukaan fotosintesis. Intensitas serangan (IS) pada Afdeling IV dan Afdeling V bervariasi antarblok dengan kisaran nilai 0%–28,57%. Berdasarkan hasil perhitungan jumlah dan rataan selama empat minggu, pada Afdeling IV intensitas serangan tertinggi terdapat pada Blok 2 dengan rataan sebesar 23,21%, sedangkan pada Afdeling V terdapat pada Blok 4 dengan rataan sebesar 17,86%. Sebagian besar blok lainnya menunjukkan rataan intensitas serangan yang lebih rendah, yaitu berkisar antara 8,93%–14,29% pada Afdeling IV dan 10,72%– 12,50% pada Afdeling V, sehingga termasuk dalam kategori serangan ringan. This study is entitled Inventory of Bagworm Pest (Metisa plana) on Oil Palm (Elaeis guineensis Jacq.) at PT Perkebunan Nusantara IV, Dolok Ilir Unit, Regional II. The aim of this study was to identify the level of bagworm pest infestation and to analyze the infestation intensity (IS) across several observation blocks in Afdeling IV and Afdeling V. Observations were conducted directly over four weeks during July– September 2025. The data obtained were analyzed descriptively to determine the category of infestation levels in each block. The results showed that bagworm pest infestation was characterized by damage symptoms in the form of brownish to blackish spots on leaflets, which potentially reduce the effective surface area for photosynthesis. The infestation intensity (IS) in Afdeling IV and Afdeling V varied among blocks, ranging from 0% to 28.57%. Based on the total and mean calculations over four weeks, the highest infestation intensity in Afdeling IV was found in Block 2 with a mean of 23.21%, while in Afdeling V it was found in Block 4 with a mean of 17.86%. Most other blocks showed lower mean infestation intensities, ranging from 8.93%–14.29% in Afdeling IV and 10.72%–12.50% in Afdeling V, which are categorized as light infestation levels. |
