Background/purpose: This study aims to formulate an effective communication strategy model implemented by Kodim 0317/TBK in instilling national awareness among senior high school students in Karimun Regency. The research addresses the need for adaptive, culturally contextualised civic education strategies in response to the vulnerability of students in border areas to external ideological influences. Materials/methods: A qualitative approach was adopted to explore the interaction dynamics between Babinsa (village supervisory non-commissioned officers) as military actors and students as strategic targets of civic education. Data collection techniques included in-depth interviews, participatory observation, focus group discussions (FGDs), and document analysis. The data were analysed using the Miles, Huberman, and Saldana technique, supported by source and methodological triangulation. Results: The findings show that the success of Kodim 0317/TBK's communication strategy relies on seven key components: (1) integration of theory and practice, (2) contextual local adaptation, (3) use of digital and social media, (4) participatory educational methodology, (5) dynamic evaluation, (6) capacity building for Babinsa, and (7) a scientifically structured implementation phase. Activities such as group discussions, military drills, educational videos, and community projects enabled students to not only understand but actively internalise national values. Conclusion: This study contributes to the development of a more humanistic, inclusive, and evidence-based military-civil communication model. It highlights the importance of symbolic communication, cultural adaptation, and student participation in shaping a resilient national identity amid globalisation challenges.
