<![CDATA[Law enforcement in border areas plays a vital role in safeguarding state sovereignty and maintaining territorial security. However, its implementation is often constrained by structural and contextual challenges, including difficult geographical access, limited infrastructure and operational facilities, and complex socio-cultural dynamics within border communities. These conditions contribute to persistent issues in controlling undocumented cross-border movements. This study aims to assess the effectiveness of law enforcement against undocumented border crossers at the Motaain Border Post, situated on the boundary between East Nusa Tenggara, Indonesia, and Timor-Leste. The research employs a normative juridical approach, complemented by empirical legal analysis through statutory and conceptual perspectives. Data were collected from primary, secondary, and tertiary legal sources and analyzed using qualitative methods. The findings reveal that law enforcement at the Motaain Integrated Border Post demonstrates a relatively adequate level of effectiveness in managing undocumented crossings. Nonetheless, several critical challenges remain, particularly those related to geographical constraints, limited institutional capacity, and suboptimal administrative coordination among relevant agencies. These issues hinder the optimal implementation of border control measures. In conclusion, while current law enforcement practices have achieved moderate effectiveness, significant improvements are necessary to enhance overall performance. Strengthening institutional capacity, integrating advanced surveillance technologies, improving administrative coordination, and developing early warning systems are recommended as strategic measures to optimize border law enforcement in this region.]]>
