<![CDATA[Mosquito control in community settings still relies heavily on chemical-based products, while the utilization of natural materials and biomass waste as alternative mosquito-repellent products remains limited. This Community Service (PkM) program aimed to improve the knowledge and practical skills of members of the Serengan Family Welfare Empowerment (PKK) group in utilizing lemongrass, cloves, agarwood, and coconut shell waste to produce SEGARA mosquito-repellent briquettes and promote a value-added product with economic potential. The program was implemented through educational sessions, demonstrations, hands-on briquette production training, and pre- and post-test evaluations. Three briquette formulations (F1, F2, and F3) were prepared and evaluated to determine the most suitable formulation. The results showed that 10 kg of coconut shell waste was successfully utilized as raw material. Formulation F2 was selected as the optimal formulation because it exhibited a strong aroma of lemongrass, cloves, and agarwood, good structural integrity, approximately 52 minutes of burning time, stable combustion, and relatively low smoke production. Participants’ knowledge improved, with the mean score increasing from 62% in the pre-test to 85% in the post-test. The program also successfully produced packaged SEGARA briquettes in labeled standing pouches, demonstrating potential as a community flagship product and source of productive economic activity.]]>
