Increasing household plastic bottle waste and the underutilization of backyard land require community-based solutions. This community service program aimed to improve the knowledge and skills of the Women Farmers’ Group (KWT) in Sawaru Village, Camba Subdistrict, Maros Regency, in reusing plastic bottles as hydroponic media for Family Medicinal Plants (TOGA) and developing a community-based Living Pharmacy. The program adopted the Participatory Rural Appraisal (PRA) approach through five stages: socialization, training, technology implementation, mentoring, and evaluation. Fifteen KWT members participated in training on wick-system hydroponics using recycled plastic bottles and cups, TOGA cultivation, and Living Pharmacy management. Evaluation involved pre-tests, post-tests, and questionnaires analyzed using descriptive quantitative methods. The results showed that the average knowledge score increased from 46.67 to 88.00, with an N-Gain of 0.77, categorized as high. Participant responses were positive, with 86.67% strongly agreeing and 13.33% agreeing that the program was beneficial. All participants (100%) expressed willingness to continue hydroponic TOGA cultivation independently at home. These findings indicate that reusing plastic waste as hydroponic media provides a simple, environmentally friendly, and sustainable alternative for optimizing home gardens. The program also promotes community self-reliance through waste reduction, medicinal plant cultivation, and productive use of household land.
