Corruption is a special offense that is regulated separately outside the Criminal Code. In the process of handling corruption cases, the principle of priority or precedence in the settlement process applies. This is following Article 25 of Law no. 20 of 2001 concerning Amendments to Law Number 31 of 1999 concerning the Eradication of Criminal Acts of Corruption, which states that investigations, prosecutions, examinations in courts of corruption cases take precedence over other cases in order to be resolved as soon as possible. The problems in this study are how to regulate the law of corruption in order to achieve legal certainty (Research Study at the Tanjung Pinang Police Criminal Investigation Unit), how to implement corruption law enforcement to create legal certainty (research study at the Tanjung Pinang Police Criminal Investigation Unit) and what factors become an obstacle or obstacle as well as a solution to law enforcement for corruption in order to realize legal certainty (Research Study at the Tanjungpinang Police Criminal Investigation Unit). This study aims to determine the legal regulation of corruption in order to create legal certainty (research study at the Tanjung Pinang Police Criminal Investigation Unit), to determine the implementation of the juridical analysis of corruption law enforcement in order to realize legal certainty (Research Study at the Tanjung Pinang Police Criminal Investigation Unit), to find out factors that become obstacles or obstacles as well as Law Enforcement Solutions for Corruption in order to Realize Legal Certainty (Research Study at the Tanjungpinang Police Criminal Investigation Unit). This study uses a descriptive method by using a normative approach (legal research) to obtain primary data through field research. The results of the study indicate that Law Enforcement of Corruption Crimes to Achieve Legal Certainty (Research Studies at the Tanjungpinang Police Criminal Investigation Unit) has basically been carried out well, although there are still many obstacles in the field, especially the substance and legal culture. It is necessary to have a firm legal regulation that provides a deterrent effect to perpetrators of corruption.
