Indonesia is greatly interested in maritime borders with other countries as a maritime country. This is because it influences the country’s security and citizens’ socio-economy. As is known, the number of fishermen in Indonesia is vast, around 1,500. 000 inhabitants. There are several ways to create a territorial sea boundary with another country. The 1982 United Nations Convention on the Law of the Sea (UNCLOS) governs the Territorial Sea and the Exclusive Economic Zone (ZEE). There are severe repercussions for fishermen of territorial waters with other countries if boundary issues are not well agreed upon, especially economically. The impact of conflict is not widespread for fishermen at sea. If not maximized, the economy will be disrupted, ultimately affecting society’s welfare. This study will examine the impact of these issues in detail and the steps that can be taken to minimize the risk to border fishermen. The policy taken by the government must be implemented for the safety and welfare of Indonesian fishermen because fishermen are widespread throughout Indonesia, including along the coastline that reaches 95,181 kilometers in length and on many small islands, especially those bordering waters with other countries. Moreover, countries bordering quite a lot there are ten countries. The method used is qualitative, and the type of research is normative with literature studies.
