One point of securing the border is from the regionalism perspective. Analysis of the role and whereabouts of TNI Military Forces, Battleships and Combat Aircraft in the outer border regions of Indonesia, can be correlated with the conditions of the area, as well as various national interests that must be secured. Region is defined as a group of countries that have geographical proximity because it is in one particular region. The main difference between realist and institutionalist (idealist) perspectives is about the most important aspects in determining attitudes towards regional security. The realists consider that the Military is the most important factor of Security, this can be analogous to the Corbett concept. Meanwhile, institutionalists say it is not only the military which is the most important aspect of regional security, but also the political and social fields. This can be analogous to the concept of Mahan. Therefore, collaboration from both perspectives is expected to be able to answer the problems that develop in the North Kalimantan border region. In line with national interests, border security activities are efforts to protect the existence of the state, which is marked by the protection of sovereignty, population, and territory from various types of threats. This conception is part of an understanding of national security, which is essential “the ability of the state to protect what is determined as core values, where its achievement is a continuous process, using all elements of force and available resources, and covers all aspects of life”. In the strategic security scheme, especially in border areas, the state does not hesitate to prioritize methods of military reinforcement, one of which is the construction of forward military bases.
