<![CDATA[Land occupies an important position in Indonesian society because it possesses economic, social, cultural, and legal values. The increasing value of land creates a need for a land administration system capable of providing certainty regarding the subject, object, and legal status of land rights. Law Number 5 of 1960 concerning Basic Agrarian Principles establishes land registration as an instrument for achieving legal certainty. This study aims to analyze the position of land registration within Indonesian agrarian law, the forms of legal certainty and protection generated through land registration, and the relevance of the land registration system in the era of digital land services. This research applies normative legal research using statutory, conceptual, and case approaches. The analysis employs Gustav Radbruch’s theory of legal certainty, Philipus M. Hadjon’s theory of legal protection, and Soerjono Soekanto’s theory of legal effectiveness. The study finds that land registration constitutes an important instrument for ensuring legal certainty and protection; however, a land certificate does not constitute absolute evidence of ownership. Legal certainty can only be achieved when physical data, juridical data, certificate issuance procedures, and actual possession of land correspond with one another. Electronic land registration may improve efficiency and transparency, but it must be supported by accurate data, reliable information systems, and effective protection of lawfully acquired land rights.]]>
