"Fill My Plate" Educational Action: Improving Nutritional Literacy and Healthy Habits Among Madiun Gen Z
Keywords:
Nutritional Literacy; Fill My Plate; Generation Z; Vocational Students; Balanced DietAbstract
This community service–based study aimed to improve nutritional literacy and promote balanced dietary habits among Generation Z adolescents through an interactive “Fill My Plate” (Isi Piringku) educational action. The program was conceptually grounded in adolescent developmental theory and empirically aligned with Sustainable Development Goal 3 (Good Health and Well-being), addressing the growing challenges of malnutrition, anemia, and obesity among Indonesian youth. The intervention was conducted offline at State Vocational High School 4 Madiun, East Java, targeting vocational students whose daily learning activities involve relatively high physical demands. A quantitative pre-experimental design with a one-group pre-test and post-test approach was employed to assess changes in students’ nutritional knowledge. Data were collected using validated nutrition knowledge questionnaires administered before and after the intervention. The educational action integrated multimedia presentations, visual demonstrations, interactive nutritional games, and guided group discussions based on the “Fill My Plate” framework. The results demonstrated a substantial improvement in students’ nutritional literacy, as reflected by a marked increase in mean knowledge scores from the pre-test to the post-test. Beyond cognitive gains, participants showed an enhanced ability to practically apply balanced meal composition and portioning principles in daily contexts. High levels of engagement during the activities further indicated that interactive and visual-based learning strategies are highly effective for Gen Z learners. These findings suggest that periodic, school-based interactive nutrition education plays a critical role in strengthening adolescents’ dietary literacy and fostering healthy habits as a preventive strategy against nutrition-related health risks. The study offers a replicable and scalable educational model for vocational schools to support the development of a healthy, productive future workforce. Longitudinal studies are recommended to evaluate the sustainability of behavioral changes in actual dietary intake.
