Integrity in the Civil Servant Apparatus (ASN) is crucial in improving the quality of public services, enhancing the accountability and transparency of public institutions, optimizing the use of public resources, and improving the quality of human resources. Integrity is a fundamental moral value in daily life and particularly in the workplace, including for ASN employees. One method for approaching this is through qualitative research, which is used to understand phenomena or events in-depth, through descriptive and non-numerical data collection. In qualitative research, the aim is to understand phenomena holistically and contextually, as well as to consider the role and influence of social and cultural factors in shaping these phenomena. This study uses literature review as a method for data collection. Literature review is a critical analysis of ongoing research on a specific topic or question about a particular area of knowledge in a systematic way. The findings of this research indicate that strong integrity in shaping the personality of ASN is crucial in providing high-quality public services. ASN employees with strong integrity tend to have strong moral values, such as honesty, fairness, and responsibility, which can shape good character. Good character can lead to good performance in carrying out duties and responsibilities as an ASN. Through strong integrity, ASN can maintain professionalism in carrying out their duties and responsibilities. ASN employees with good integrity will work diligently, diligently, and enthusiastically in serving the community. In addition, ASN with strong integrity can also maintain the quality of public services and avoid unethical behavior that can harm the community. The government and society need to pay special attention to the formation of ASN integrity, both in the recruitment process, career development, and public ethics training. The formation of good integrity can also be achieved through strict supervision and severe sanctions for ASN ethical violations. Thus, strong integrity can shape good ASN personalities, provide high-quality public services, and maintain the image and trust of the community in government institutions.
