Implementation of the Total War Strategy (SISHANTA) in Efforts to Defend the South Sumatra Region

South Sumatra's coastal area is highly vulnerable to external attacks due to its sloping terrain, which makes it easier for enemies to land large numbers of troops. The proximity of Bangka Island, which acts as a natural barrier, further increases the risk of invasion from two directions. This research aims to analyze strategic measures for defending the region against potential invasions through the application of the Total Defense Strategy (SISHANTA). Utilizing a qualitative methodology, this study is based on a comprehensive literature review to examine defense strategies. The findings of this research highlight the formulation of a Total Defense Concept for South Sumatra, which is an integrated approach that involves all national components, including military, civilian, and government sectors, to establish a comprehensive defense system. The study emphasizes the importance of community involvement, strong local governance, and strategic geographical management in ensuring the effectiveness of the total defense strategy. This comprehensive framework offers practical recommendations for future defense policies, focusing on strengthening resilience, enhancing military readiness, and fostering collaboration across sectors. The results provide valuable insights into how regional defense strategies can be applied in coastal areas with similar vulnerabilities.
