Until 2022 OJK as the regulator curbed illegal P2P lending platforms with POJK 10/2022, a more assertive and detailed in regulating this industry. Although OJK has issued a new regulation POJK 10/2022, it is inevitable that risks can still occur.

Therefore, the purpose of this study is to understand and analyze how OJK's supervision processes and procedures for platforms, to assess their effectiveness in ensuring platform compliance with applicable regulations.
