The border between two countries is an area that often faces complex legal problems. This condition involves conflicts of interest between countries that share borders and emerging issues related to jurisdiction, security, migration, trade, environment, and human rights. This paper aims to analyze the role of state law and policy in dealing with legal problems at the border. First, the analysis focused on state law as a legal framework governing relation between countries on the border. Countries try to address issues that arise at borders through bilateral and multilateral agreements. The concept of state sovereignty, international law, and the principles of diplomacy are used as legal foundations for resolving disputes and promoting cooperation on borders. Second, the role of policy is also crucial in dealing with legal problems at the border. The research method used is a descriptive-analytical method with a qualitative approach. The data obtained will be analyzed with a normative sociological approach to understanding the social aspects and norms involved in cross-border deliberation. Data were collected through participatory observation, in-depth interviews, and document studies. The respondents involved in this study were community leaders, village leaders, and local government representatives who had knowledge and experience related to cross-border problems. Flexible and adaptive policies need to be developed considering local communities' specific needs. Through active dialogue and participation, suitable solutions can be found to ensure the effective implementation of laws and policies in Temajuk Village.
