Development of national resilience strategies in Indonesia's marine border areas, especially in the northern Natuna sea, Malacca strait, and Sulawesi sea

As the largest archipelago in the world, Indonesia has a vast marine area with strategic potential and high vulnerability, especially in border areas. This research aims to analyze the condition of national resilience in Indonesia's marine border areas, identify threats and challenges, and formulate strategies to strengthen national resilience. The method used is qualitative-descriptive with literature study, policy document analysis, and case studies in the North Natuna Sea, Malacca Strait, and Sulawesi Sea. The results showed that threats to Indonesia's sea borders include unilateral claims by other countries, illegal fishing activities, and the weak welfare of coastal communities. The strategy to strengthen national resilience is carried out through Defense approaches, diplomacy, coastal economic development, as well as strengthening maritime culture and awareness of the state's Defense. In conclusion, strengthening national resilience in the marine border region requires synergy between agencies and active community participation to maintain the sovereignty and territorial integrity of the Republic of Indonesia.
