Attack Levels of the Leafroller Pest (Erionota thrax L.) on Kepok Banana Plants (Musa sp.) in South Sumatera Province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembangg 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Banana (Musa sp .) is a popular tropical fruit with high economic value in Indonesia. Bananas are spread across almost the entire region of Indonesia, including South Sumatra Province. A common pest that attacks banana plants is the leaf roller caterpillar (E. thrax L.). The purpose of this research was to determine the intensity of the leaf roller pest attack on Kepok banana cultivars (Musa sp.) caused by E. thrax L. in several regencies of South Sumatra Province. This research was conducted in 13 cities/regencies in South Sumatra. This research was carried out from May to October 2023. The method used in this research is a purposive sampling method directly in the field by determining a central point and creating an imaginary circle with a diameter of 100 meters. The results of this study show that each regency/city has a varying number of Kepok banana clumps and stems. The percentage of E. thrax attack on Kepok banana plants was obtained by looking at the number of healthy and attacked stems using the formula listed in the methodology. The highest percentage of leaf roller pest attack on the Kepok banana cultivar was in East Ogan Komering Ulu Regency with a percentage reaching 50.97%, while the lowest percentage of leaf roller pest attack on the Kepok banana cultivar was in 3 regencies: Banyuasin, Palembang, and North Musi Rawas with an attack percentage of 0%]]>
