Abstract
Community service initiatives grounded in coastal ecosystems represent a tangible manifestation of the non-military defense paradigm, which is increasingly relevant in addressing multidimensional threats. The activity, conducted by the Faculty of Defense Strategy at the Republic of Indonesia Defense University (Unhan RI) in Kampung Bahari Nusantara, Sidodadi Village, Teluk Pandan Subdistrict, Pesawaran Regency, South Lampung, on May 22, 2026, involved the planting of 5,000 mangrove seedlings, environmental education, and the distribution of basic food aid to 300 fishers. This article analyzes these activities within the conceptual frameworks of coastal area resilience, sustainable ecosystem management, and the synergy between defense institutions, academia, and local communities. Employing a descriptive-qualitative approach through participatory observation and literature review, the findings indicate that mangrove rehabilitation not only contributes to mitigating coastal abrasion and climate change impacts but also strengthens the socio-economic resilience of coastal communities and serves as a vehicle for instilling the values of national defense among students. This activity recommends the reinforcement of the Kampung Bahari Nusantara program as a model for inclusive and sustainable coastal empowerment and proposes the integration of the silvofishery concept to enhance the economic value of mangrove conservation.
