Territorial Operations Strategy of Korem 131/Santiago in Securing the Sangihe and Talaud Islands to Support National Sovereignty

The border areas of Sangihe Islands Regency and Talaud Islands Regency hold strategic importance as they are directly adjacent to the Philippines and located along maritime routes vulnerable to sovereignty violations.. This study aims to analyze the implementation of the Territorial Operation strategy of Korem 131/Santiago, The research employed a qualitative descriptive-analytical approach through interviews, field observations, and document analysis. The findings indicate that the implementation of the strategy has been carried out through integrated development of geographic, demographic, and social aspects, supported by territorial patrols and intensive social communication. However, operational effectiveness remains affected by archipelagic geographical constraints, limited personnel relative to the vast area of responsibility, inadequate maritime transportation facilities, and uneven communication systems. Interagency coordination has also not been fully integrated into a unified operational system. In conclusion, the implemented strategy is relevant and adaptive to the characteristics of the region but requires further optimization through enhanced personnel capacity, modernization of maritime surveillance facilities, integration of territorial information systems, increased budgetary support, and strengthened intersectoral synergy to ensure sustainable national sovereignty.
