Abstract

Sea grapes (Caulerpa spp.) are abundantly available in the coastal waters of Tual City; however, their utilization remains highly limited. This community service initiative aimed to empower coastal communities, particularly women-led micro, small, and medium enterprises (MSMEs) and fisheries extension officers, through the transfer of a zero-waste processing technique for sea grape jam production. Grounded in community empowerment theory, the program used a participatory approach that consisted of preparation, hands-on training, and evaluation involving 24 participants. The evaluation results showed a substantial improvement in participants’ technical knowledge, with mean scores increasing from 32.3% in the pretest to 97.6% in the post-test, representing a 291.5% increase. Beyond technical skill acquisition, the intervention successfully reshaped participants’ perceptions and fostered strong entrepreneurial motivation to develop marine-based household enterprises. In conclusion, integrating local marine resource innovation with targeted capacity building not only strengthens coastal economic resilience but also provides a socioeconomically and environmentally sustainable model for regional microenterprise development.
