Penyemprotan Insektisida Meggunakan Drone untuk Pengendalian Hama Ulat Kantong (Clani tertia) pada Pertanaman Tanaman Kelapa Sawit Menghasilkan

The oil palm plant (Elaeis guineensis Jacq.) is a plant that has quite bright development prospects in the Indonesian economy, but it has various obstacles, one of which is the attack of an oil palm leaf-eating caterpillar, namely bagworms (Clania tertia). The research location in kandis subdistrict , the level of attack by bagworm pests is quite high, while manual control of bagworm is less efficient and precise, so control using drones can overcome this problem. The aim of this research is to determine the number and level of pest attacks and to find out whether the bagworm control efforts that have been carried out, namely by spraying using drones, have been effective. The data used is primary data and secondary data. Primary data includes the results of observations in the field by means of a pest census, and secondary data is data from the previous pest census within the company in October 2023. The blocks with the blocks with the highest level of pest attacks are blocks G60, G59, and G61, amounting to 9 individu/frond, 7 individu/frond, and 6 individu/frond, which are included in the high category. The lowest level of bagworm attacks was in blocks G57, G56, and G55, with the number of pests being 0.4 individu/frond, 0.4 individu/frond, and 0.5 individu/frond, with an attack level of <5 individu/frond, which was in the low category. After chemical control was carried out using drones in blocks G60, G59, and G61, the level of pest attacks decreased to 0.27, 0.21, and 0.2 heads/fronds, which were included in the low category.
