<![CDATA[The management of Indonesia's Border Crossing Posts (Pos Lintas Batas Negara/PLBN) in land border areas presents a critical normative gap between the country's international legal obligations and their actual implementation. This study departs from prior descriptive approaches by offering a critical normative-gap analysis that identifies specific disharmonies between bilateral agreements, international conventions, and national legislation governing PLBN operations. Employing a normative juridical method with statute, conceptual, and case approaches, this research examines three focal issues: (1) the normative gap between Indonesia's international legal commitments under instruments such as the United Nations Charter, Vienna Convention on Consular Relations 1963, Revised Kyoto Convention, International Health Regulations 2005, and the United Nations Convention against Transnational Organized Crime (UNTOC), and their domestic implementation; (2) the legal factors generating regulatory disharmony in PLBN governance, particularly the inconsistency between bilateral Border Crossing Agreements with Malaysia and Timor-Leste and national legislation; and (3) specific case-based evidence of implementation failures, including unauthorized border crossings at PLBN Motamasin and the pending boundary delimitation in the Noel Besi Citrana and Bidjael Sunan Oben segments with Timor-Leste. The findings reveal that regulatory disharmony, institutional fragmentation in the CIQS system, inadequate human resource capacity, and unresolved boundary disputes constitute structural legal deficits that undermine the effective governance of PLBN. This article recommends a comprehensive legal harmonization strategy, strengthened bilateral diplomatic engagement, and institutional reform grounded in international legal standards. ]]>
