Stunting remains a major nutritional challenge in Indonesia, particularly among vulnerable households with limited access to diverse and nutritious foods. This community service program aimed to improve household food production and community capacity among stunting-affected families in Penfui Timur Village, Kupang Regency, East Nusa Tenggara, through healthy lifestyle education and the implementation of integrated aquaponics–poultry technology. The program employed a Participatory Action Approach involving 12 households in initial assessment, education, technical training, technology implementation, and monitoring and evaluation. Changes in knowledge of healthy lifestyle practices were assessed descriptively using pre-test and post-test scores, while technology adoption and food production were evaluated based on program monitoring records. The average knowledge score increased from 45 to 78, indicating a descriptive improvement following the educational intervention. Technology adoption reached 83.3%, with 10 of the 12 participating households adopting the introduced technology. The six integrated production units generated a total of approximately 20 kg of vegetables and 20 kg of catfish per month. Total egg production across the units or households monitored increased from 8 to 20 eggs per month. These findings demonstrate the potential of combining health education with integrated household food production technology to diversify food sources and support household food security. However, household food consumption, economic benefits, and child nutritional outcomes were not directly measured. Further evaluation is therefore needed to assess the sustainability of technology adoption, actual household food consumption, economic impacts, and nutritional outcomes. This participatory approach may provide a practical model for strengthening household food production and community capacity in other communities facing similar challenges.
