<![CDATA[Online gambling has become a controversial issue in Indonesia, with serious social impacts. One of the most noticeable impacts is the increase in cases of gambling addiction, which impacts individuals' mental health and financial situation. This social impact also extends to families, causing conflicts and negatively affecting children and spouses. In addition, illegal online gambling can be used for illegal money laundering. Thus, the development of online gambling in Indonesia has caused significant social impacts, especially related to the increase in addiction cases, serious financial problems, and family conflicts. In addressing this issue, the Indonesian government, through the Financial Services Authority (OJK), takes a crucial role in monitoring and blocking the flow of money from illegal online gambling. Qualitative research methods were used to gain in-depth insight into OJK's actions and processes in its law enforcement efforts related to illegal online gambling. A normative juridical approach with literature study became the foundation of the research. The results show that OJK, as a financial sector supervisory institution, has an important role in overseeing suspicious financial transactions related to illegal gambling. OJK cooperates with the Ministry of Finance to exchange information and track cross-border money flows. Through intensive surveillance, OJK focuses on identifying signs of suspicious activity, including the use of digital payment methods and unusual transaction patterns. The importance of OJK's role lies in its contribution to protecting the public from the negative impact of illegal gambling. By blocking the flow of money from online gambling, OJK supports efforts to prevent illegal gambling and maintain the integrity of Indonesia's financial sector. Through commitment, cross-sector cooperation, and the application of technology, OJK plays a key role in maintaining the safety and stability of the financial sector and protecting the public from adverse social and economic impacts]]>
