Shifts in the strategic environment, technological advancements, and rising public expectations regarding the quality of public services are driving government organizations to adopt adaptive governance in the delivery of immigration services. This study aims to analyze the implementation of adaptive governance to improve immigration service quality at the Banggai Class II Non-TPI Immigration Office, identify the factors supporting and hindering its implementation, and explain its contribution to enhancing public service quality. A qualitative approach utilizing a case study design was employed. Informants were selected via purposive sampling and included the office head, structural officials, service staff, and service users. Data were gathered through in-depth interviews, observation, and document analysis, and subsequently analyzed using an interactive model involving data condensation, data display, and conclusion drawing. The findings indicate that adaptive governance is implemented through adaptive leadership, institutional flexibility, organizational learning, service innovation, collaboration, and the use of information technology. This implementation contributes to improved effectiveness, efficiency, transparency, and quality of immigration services. Supporting factors include leadership commitment, employee capabilities, technological innovation, and collaborative networks, while obstacles include a lack of digital infrastructure, disparities in public digital literacy, and the need to enhance technological skills. The study concludes that strengthening adaptive governance on a continuous basis can bolster organizational capacity to deliver immigration services that are responsive, innovative, and focused on public needs.
