Results and Discussion Analysis of the Dimensions of KPK Public Service Quality is a critical step in exploring the commitment and success of the institution in providing quality and transparent services to the public. Through a careful approach to the five dimensions of service quality according to Tjiptono's SERVQUAL model (1996), namely Tangibles, Reliability, Responsiveness, Assurance, and Empathy, we can uncover the crucial elements that are the main foundation for the KPK. In analyzing the Tangibles dimension, it can be seen that the KPK shows its seriousness in providing public services by providing adequate facilities and infrastructure, creating positive physical evidence such as waiting rooms, X-Ray machines, and library rooms. In line with that, the Reliability dimension provides an overview of the quality of the KPK's reliability which is reflected in the statistics of the success of preventing and prosecuting corruption. Data from 2022 shows that the KPK has succeeded in handling 95% of reported corruption cases with significant penalties. This achievement is proof of the institution's consistency and accuracy in eradicating corruption, creating a high sense of public trust in the institution's reliability. . The conclusion can be emphasized that the KPK has succeeded in building a solid foundation in providing quality public services, which in turn affects public trust in this institution. From the results of the analysis of the dimensions of the quality of KPK public services, it can be concluded that the purpose of the study to understand the extent to which these dimensions affect public trust has been achieved
