However, unhealthy eating behaviors, low consumption of fruits and vegetables, excessive intake of sugar, salt, and fat, and limited awareness of sustainable food consumption remain common among adolescents. Educational interventions are needed to improve knowledge and awareness regarding healthy and sustainable dietary practices. Objective: This study aimed to evaluate the effectiveness of a community-based educational program in improving knowledge of healthy and sustainable dietary practices among adolescents at Al-Hikmah Islamic Boarding School. Methods: A community service-based educational intervention was conducted among 240 high school students from grades 10, 11, and 12 at Al-Hikmah Islamic Boarding School, Lampung, Indonesia. The program consisted of interactive lectures, group discussions, and question-and-answer sessions focusing on balanced nutrition, healthy eating habits, sustainable food consumption, reduction of food waste, and the role of dietary behavior in achieving Sustainable Development Goals (SDGs). Participants completed structured questionnaires before (pre-test) and after (post-test) the educational intervention. Changes in knowledge levels were assessed descriptively. Results: The educational intervention was successfully implemented with active participation from all participants. Post-intervention assessment demonstrated a 40% increase in participants’ knowledge compared to baseline measurements. Participants showed improved understanding of balanced nutrition principles, healthy food choices, responsible food consumption, local food utilization, and food waste reduction. The program also increased awareness regarding the relationship between dietary practices, environmental sustainability, and long-term health outcomes. Conclusion: The educational intervention effectively improved adolescents’ knowledge and awareness regarding healthy and sustainable dietary practices. School-based nutrition education programs within Islamic boarding school settings may serve as a strategic approach to promoting lifelong healthy behaviors and supporting Sustainable Development Goals, particularly SDG 2 (Zero Hunger), SDG 3 (Good Health and Well-Being), and SDG 12 (Responsible Consumption and Production).</p> Risti Graharti Intan Kusumaningtyas Linda Septiani Shinta Nareswari Femmy Andrifianie Terza Aflika Happy Copyright (c) 2026 SEVA : JURNAL PENGABDIAN MASYARAKAT 2026-06-15 2026-06-15 1 1 1 8
