<![CDATA[This thesis examines the fundamental concept of the Single Prosecution System implemented by public prosecutors within Indonesia's integrated criminal justice system. The study focuses on the position of the Public Prosecution Service (Kejaksaan) as the dominus litis in the prosecution process and the urgency of integrating the criminal justice system to achieve effectiveness, legal certainty, and justice. This study employs a normative juridical legal research method, which emphasizes the examination of legal norms (law in the books). The research primarily relies on statutory regulations and library materials as secondary legal sources. The approaches applied in this research include the statutory approach, literature approach, conceptual approach, historical approach, comparative approach, and case approach. The legal materials consist of primary legal sources, including the 1945 Constitution of the Republic of Indonesia, Law Number 31 of 1997 concerning Military Courts, the Indonesian Code of Criminal Procedure (KUHAP), Law Number 11 of 2021 concerning the Amendment to Law Number 16 of 2004 on the Public Prosecution Service of the Republic of Indonesia, Law Number 31 of 1999 in conjunction with Law Number 20 of 2001 concerning the Eradication of Corruption Crimes, and Law Number 16 of 2004 concerning the Public Prosecution Service of the Republic of Indonesia. The findings reveal that strengthening the authority of public prosecutors under the Single Prosecution System can improve coordination among law enforcement agencies and reinforce the integration of the criminal justice system. However, effective implementation requires regulatory harmonization and institutional strengthening. Furthermore, the future implementation of the Single Prosecution System in Indonesia does not imply the physical centralization of all prosecutors within a single prosecution office. Rather, it refers to the centralization of prosecutorial policy, standardization, and accountability under a single authority, namely the Attorney General. Under this system, the Corruption Eradication Commission (KPK) and the Military Prosecutor's Office (Oditurat Militer) would continue to exercise their respective specialized functions while acting "for and on behalf of" a unified and integrated national prosecution system.]]>
