Abstract
Abstract: This community service program aimed to improve adolescents’ knowledge of balanced nutrition guidelines through an interactive educational program at SMPN 28 Jakarta. The identified problem was the low level of students' knowledge regarding the “Isi Piringku” concept, which may affect nutritional status and eating habits among adolescents. The method was conducted through three stages: preparation, implementation, and evaluation. The intervention consisted of nutrition education delivered using PowerPoint media, followed by a practical activity involving the arrangement of the Isi Piringku puzzle. The evaluation employed a pre-test and post-test design involving 30 seventh-grade students to assess changes in knowledge before and after intervention. Data were analyzed using the Wilcoxon test, which showed a significant difference between pre-test and post-test scores (p=0.003). The proportion of students with good knowledge increased from 6,7% to 26,7% after the intervention. Monitoring conducted three days after the education session indicated that some students had begun applying the “Isi Piringku” concept, although food availability at home remained a challenge. This study concludes that education using visual media and interactive practices is effective in improving adolescents' nutritional knowledge; however, support from families and schools is necessary to optimize sustainable behavioral changes.
