Application of Blockchain Technology for Strengthening The Integrity of The Electronic Investigation Management System (E-Mp) in The Indonesian National Police

This study discusses the application of blockchain technology in strengthening the integrity of the electronic investigation management system (e-MP) within the Indonesian National Police (Polri). As demands for transparency, accountability, and data security in the investigation process increase, the e-MP system faces serious challenges related to potential data manipulation, weak internal controls, and limited objectively verifiable digital footprints. Blockchain technology offers a solution with its decentralized, transparent, and immutable characteristics, thus enhancing the validity of digital evidence and preventing illegal intervention in legal processes. This study uses a normative juridical approach by analyzing recent regulations such as Law No. 4 of 2023 on the Development and Strengthening of the Financial Sector (P2SK), Law No. 27 of 2022 on Personal Data Protection (UU PDP), as well as technical provisions from the Financial Services Authority (OJK) and Commodity Futures Trading Regulatory Agency (Bappebti) regarding digital assets. The analysis results show that the implementation of blockchain in e-MP requires regulatory readiness, institutional capacity strengthening, and the development of integrated digital infrastructure. The legal implications include the need for adjustments in criminal procedural law, personal data protection, and national policy strategies in the digital law sector. This study recommends the formulation of cross-sector policies, training for law enforcement officers, and institutional cooperation to ensure the technology's implementation aligns with legal and human rights principles. With the right approach, blockchain has the potential to become a main pillar in the reform of a modern and trustworthy investigation system.
