<![CDATA[Corruption is one of the serious problems that hinders development, social justice, political stability, and public trust in state institutions. Previous studies have shown that law enforcement against corruption in Indonesia continues to face various challenges, including political influence on sentencing, disproportionality between sanctions and state losses, weak coordination among law enforcement institutions, and limited institutional independence. Comparative studies have also indicated that the independence of anti-corruption institutions, judicial credibility, governance quality, and public participation are important factors in improving the effectiveness of corruption eradication. Based on these issues, this study aims to analyze and compare criminal sanctions for corruption offenses in Indonesia, Malaysia, and Singapore and to identify factors influencing law enforcement effectiveness and the deterrent effect of criminal sanctions. This study employs a qualitative method with a comparative legal approach. Data were obtained through a systematic literature review of scientific journals, books, legislation, government reports, and publications from international organizations, complemented by semi-structured interviews with legal experts and practitioners. The data were analyzed thematically and comparatively based on legal frameworks, types of sanctions, sentencing patterns, institutional arrangements, law enforcement processes, and socio-political factors. Data validity was strengthened through source triangulation. The findings reveal differences in the effectiveness of anti-corruption law enforcement among the three countries. Indonesia has a relatively comprehensive legal framework; however, its implementation continues to face challenges, including political intervention, weak institutional independence, sentencing inconsistencies, limited resources, low asset recovery, and limited public participation. In contrast, Singapore demonstrates stronger law enforcement effectiveness through the independence of the Corrupt Practices Investigation Bureau (CPIB), relatively efficient judicial processes, consistent application of sanctions, and stronger reporting and whistleblower protection mechanisms. Malaysia has made progress in anti-corruption governance but continues to face challenges related to institutional independence and political influence. The findings indicate that the effectiveness of criminal sanctions is determined not only by the severity of punishment but also by the independence of law enforcement institutions, judicial integrity, sentencing consistency, asset recovery, social norms, and public participation. Therefore, strengthening institutional independence, reforming the judiciary, promoting anti-corruption education, improving asset recovery mechanisms, and enhancing international cooperation are necessary to strengthen the effectiveness of corruption eradication in Indonesia.]]>
