<![CDATA[Mosquito-borne diseases frequently occur in tropical regions, such as Indonesia. The use of synthetic chemical repellents can pose health and environmental issues. Essential oil-producing plants, such as lemongrass (Cymbopogon sp.), have significant potential as safe, natural bioinsecticides. However, their utilization by the partner community remains limited to culinary spices or traditional beverages. This community service program aimed to improve the knowledge and skills of the Gerakan Ekonomi Kaum Ibu (GEMI) partner community in processing essential oil-producing plants to produce household bioinsecticides. This program was implemented using the ABCD (Asset-Based Community Development) approach, which involved mapping local essential oil plant assets followed by participatory training to transform these assets into household-scale bioinsecticide products. The impact of this program was evaluated using pretest and posttest approaches, with indicators including increases in average scores, shifts in the score distribution, and improved understanding of essential oil concepts. These findings suggest that the ABCD approach and participatory demonstrations can be used to support the transfer of applicable skills, as evidenced by an increase in the average score from 80.48% to 91% (a 10.52% increase), a clear shift in score distribution from the 70–80 range to 90–100, and the ability of all participants (100%) to produce both dry and wet bioinsecticides. The resulting bioinsecticide products have potential advantages, including the use of affordable local materials, simple production processes, environmental friendliness, and the potential to be developed into economically valuable, independent home-based enterprises.]]>
