<![CDATA[Monitoring compliance with administrative sanctions is a crucial tool in environmental law enforcement to ensure that businesses comply with environmental protection and management regulations. This study aims to analyze the implementation of compliance monitoring of administrative sanctions based on Minister of Environment Regulation No. 14 of 2024 in Modern Cikande Industrial Estate (MCIE), Serang Regency, and to identify the obstacles that affect its effectiveness. The novelty of this research lies in testing the implementation of the 2024 regulations in a large-scale integrated industrial zone with a multi-tiered authority structure. The study employs an empirical legal method with a sociological approach to law. The data were collected through semi-structured interviews with Environmental Supervisory Officials (PPLH) of the Serang Regency DLH and a literature review, and were then analyzed qualitatively using descriptive and prescriptive thematic analysis, with Soerjono Soekanto’s theory of legal effectiveness serving as the analytical framework. Supervision has been carried out in accordance with the provisions of Article 61 of Ministry of Environment Regulation No. 14 of 2024; however, it has not been optimal due to limited human resources, overlapping authorities, low compliance among business operators, and suboptimal utilization of the Electronic Environmental Reporting Information System (SIMPEL). These findings underscore the dominant role of law enforcement officials and resources in determining the effectiveness of oversight and serve as the basis for recommendations to strengthen institutional coordination, enhance the capacity of oversight officials, and optimize SIMPEL]]>
