Abstract

Inconsistencies in legislation can significantly hinder the effectiveness and efficiency of the central and local government administrations. The Indonesian government requires standard harmonization of each piece of legislation to prevent such problems. However, this process is often manual and requires the involvement of multiple experts with varying backgrounds. This leads to high resource expenses regarding human resources, cost, and time. To address this, a software system should be developed to detect potential disharmony among legislation. However, the system requires a well-constructed legislation conceptual model represented in an appropriate modeling language. This research aims to develop the Indonesian local regulation ontology in web ontology language (OWL), where no such ontology exists. The ontology was created using the Ontology Development 101 methodology and evaluated using competency questions and expert judgment approaches. The resulting ontology becomes a basis for developing an automatic recommendation system to detect potentially inconsistent legislation in future works.

Abstract

This study aims to analyze the authority of Notaries and Land Deed Officials (PPAT) in controlling land-use conversion of Sustainable Food Agricultural Land (LP2B) during the transfer of land rights and to examine the juridical implications arising from such authority. The research is grounded on the existence of normative ambiguity and the lack of integration between notarial authority and spatial planning control systems, which creates legal gaps enabling formal yet unlawful land conversion. This research employs a normative juridical method with statutory, conceptual, and case approaches. The findings indicate that the authority of Notaries and PPAT remains general in nature and does not explicitly impose obligations to verify LP2B status, resulting in the suboptimal preventive function as gatekeepers. The juridical implications include potential invalidity of authentic deeds, administrative, civil, and criminal liabilities, as well as legal uncertainty and weakened spatial control effectiveness. Therefore, a comprehensive regulatory reconstruction is required to strengthen the preventive role of Notaries and PPAT in controlling land conversion in order to support national food sovereignty
