This study aims to analyze the implementation of New Public Service (NPS) principles in improving the quality of passport services at the Denpasar Class I TPI Immigration Office. The main problem raised is the low level of public satisfaction with passport processing services due to the suboptimal process, long queues, and lack of attention to the rights of the community as service users. With a qualitative approach, this study uses observation methods, in-depth interviews, and documentation to obtain data from officers and passport applicants at the research location. The results of the study indicate that the implementation of NPS principles, such as responsive, participatory, fair, and transparent services, contributes positively to improving the quality of services and public satisfaction. Integrated technology systems and priority services for vulnerable groups have succeeded in accelerating the process and increasing fairness in access to services. However, there are obstacles such as high application volumes and system disruptions that need to be addressed in order for services to be more optimal. The existence of a more efficient information system and ongoing training for officers is expected to reduce existing problems. This study also highlights the importance of the active role of the community in providing feedback to improve the quality of services. Overall, this study concludes that the integration of NPS principles can strengthen the relationship of trust between the government and the community and produce higher quality and fairer immigration services. The implementation of these principles will not only have an impact on increasing efficiency, but also on increasing transparency and accountability in the public service system.
