This emphasizes that every legal action, including law enforcement against corruption, must be oriented towards justice, legal certainty, and benefits for society. Article 1 paragraph . of the 1945 Constitution explicitly states that Indonesia is a country of law, so all aspects of government administration must be subject to applicable legal principles. Journal homepage: http://kampungjurnal. org/index. php/JPN/index ISSN: 2654-8127 Corruption is a serious problem that hinders national development and harms state finances. According to Law Number 31 of 1999 in conjunction with Law Number 20 of 2001 concerning the Eradication of Corruption, corruption is defined as an unlawful act aimed at enriching oneself or others that can harm the country's finances or economy. The high rate of corruption in Indonesia shows the need for an effective eradication strategy, one of which is through optimizing the role of the prosecutor's office in the investigation The Prosecutor's Office as a law enforcement agency has broad authority in the process of handling corruption cases. Based on Law Number 16 of 2004 concerning the Prosecutor's Office of the Republic of Indonesia which has been updated through Law Number 11 of 2021, prosecutors not only function as public prosecutors, but are also authorized to conduct investigations into certain corruption cases. This aims to accelerate the legal process and ensure the effectiveness of eradicating corruption. The professionalism of prosecutors in the investigation process is a crucial aspect in ensuring justice and legal accountability. This professionalism includes technical competence, independence, and moral integrity in handling corruption cases. According to research conducted by the Corruption Eradication Commission (KPK) in 2022, one of the main challenges in investigating corruption cases is political intervention and weak coordination between law enforcement agencies. Therefore, a high standard of professionalism is needed in the implementation of prosecutors' duties. In practice, prosecutors are faced with various obstacles in the process of investigating corruption These obstacles include difficulties in collecting evidence, the complexity of the corruption modus operandi, and the limitations of human resources and technology in supporting investigations. A study conducted by the Institute for the Study and Advocacy for Judicial Independence (LeIP) in 2023 shows that the low quality of investigations is often the main cause of the failure to prove corruption cases in court. One of the strategies in increasing the effectiveness of investigations is through the application of digital technology and strengthening cooperation between institutions. Digitalization in the investigation process, such as the use of digital forensics and electronic-based surveillance systems, can help prosecutors in collecting evidence more effectively and efficiently. In addition, the synergy between the prosecutor's office, the police, and the KPK is an important factor in tackling corruption crimes more comprehensively. The importance of prosecutorial professionalism in investigations is also supported by aspects of supervision and accountability. According to the 2024 Transparency International Indonesia report, improving internal and external oversight mechanisms for prosecutors can reduce the risk of abuse of authority and increase transparency in law enforcement. This is in line with the principles of good governance which prioritize accountability, transparency, and public participation in supervising the performance of law enforcement officials. The success of eradicating corruption does not only depend on law enforcement officials, but also on public support and firm legal policies. Regulatory reform in the criminal justice system, including strengthening punishments for corrupt perpetrators and protection for witnesses and whistleblowers, is a strategic step that needs to be implemented. In addition, increasing legal literacy for the community can help in building a better legal culture. Based on this phenomenon, this study aims to analyze the role of prosecutor professionalism in the process of investigating corruption crimes at the Aceh Besar District Attorney's Office. The focus of this research includes an analysis of factors that affect the effectiveness of investigations, obstacles faced by prosecutors in handling corruption cases, and strategies that can be applied to improve the quality of With this research, it is hoped that it can contribute to the development of policies in the criminal justice system and strengthen the professionalism of prosecutors in carrying out their duties. Efforts to eradicate corruption that are carried out systematically and sustainably will be the key to realizing clean and integrity governance in Indonesia.

Therefore, a more effective coordination mechanism is needed so that the investigation process can run more efficiently and integrate well. Strengthening this cooperation can also help in accelerating the handling of corruption cases involving a wide network and complex modus operandi.

In addition, public involvement in supervising the performance of the prosecutor's office can also be one of the steps to ensure transparency and accountability in the legal process. The success of eradicating corruption does not only depend on the professionalism of prosecutors, but also on public support and firm legal policies. Regulatory reform in the criminal justice system, including strengthening punishments for corrupt perpetrators and protection for witnesses and whistleblowers, is a strategic step that needs to be implemented. With the improvement of prosecutors' professionalism and Jurnal Pengabdian Nusantara ISSN: 2654-8127 adequate regulatory support, it is hoped that efforts to eradicate corruption in Indonesia can run more effectively and have a significant impact on national development.
