Enhancing Immigration Functions at the Motaain Cross-Border Post and Its Relation to National Resilience

Border security is very important to maintain state sovereignty, especially at the Motaain Cross Border Line (PLBN) which borders Timor Leste. This research analyzes the application of social control theory to improve immigration functions in tackling transnational crimes, as well as its relationship with the theory of national security and resilience. The method used is a qualitative approach with a case study at PLBN Motaain, involving interviews with immigration officials and security forces. The results show that the application of social control through strict supervision and cross-agency cooperation increases the effectiveness of crime prevention such as smuggling and illegal immigration. Strengthening the technology-based immigration system also strengthens the mitigation of threats to border stability. Immigration plays a strategic role in maintaining social, economic and national security balance. However, there are obstacles such as limited surveillance infrastructure and weak cross-border coordination. Improving immigration policies, strengthening the surveillance system, and enhancing bilateral cooperation with Timor Leste are needed to ensure more effective border security.
