<![CDATA[The Marunda Public Housing area faces socioeconomic challenges, including limited space, population density, and low health and nutrition awareness. These conditions necessitate innovative strategies for community empowerment, integrating health and creative economic approaches. The Community Service Program through the Marunda Nutrition House was designed to enhance nutritional literacy, entrepreneurial skills, and self-reliance among child and adolescent health volunteers. The program consisted of socialization, training, technology application, mentoring, and evaluation. Key activities involved nutrition education classes, mobile nutrition consultations, waste management into marketable products, maggot and catfish farming, and vertical vegetable gardening. Results indicated an average increase of 20 points in participants’ knowledge and significant improvements in practical skills related to organic waste processing and independent health monitoring. The program also produced educational media and community-based products with economic value. The findings conclude that a multidisciplinary collaborative approach through the Nutrition House effectively develops community potential and promotes sustainable welfare among Marunda residents.
