<![CDATA[Unhealthy snack consumption among elementary school students remains a serious public health concern in Indonesia, with many school canteen products failing to meet food safety standards. This community service program, Sigap Jajan Sehat, aimed to improve knowledge and awareness about healthy, nutritious, and safe snack consumption among students (grades 1–6) at SDN 2 Semanding, Ponorogo. The program was implemented in January 2026 as part of the Field Practice Program (PKL) of the Faculty of Public Health, Universitas Airlangga. An interactive picture-guessing method was used, combined with a pre-test and post-test to measure knowledge change. Results showed that students’ average correct answers increased from 40,4% (pre-test) to 86,8% (post-test), with 100% participation in quiz activities. These findings indicate that the intervention was able to improve elementary school students’ knowledge of healthy and safe snacks within a short period.]]>
