Cutworms population is increasing rapidly and may damage crops in Indonesia. Therefore, control of those pests is needed using bioinsecticides obtained from Pong-Pong fruit seed extract. These seeds have an active ingredient from alkaloid and steroid groups that can eliminate the worms. The seeds are prepared by mashing and mixing them with a Natural Deep Eutectic Solvent (NADES) and undergo ultrasonic-assisted extraction (UAE) with different concentration and sonication times to obtain the most optimal one by checking the most lethal extract given to the worms. Tests using Liebermann-Burchard, FTIR and LCMS have identified the components of the extract.
