This study examines the implementation of the general principles of good governance in public service delivery in Bandung City and formulates an operational model for strengthening legal compliance and service quality. It employs normative legal research using statutory, conceptual, and case approaches, supported by document analysis of national legislation, Bandung municipal legal instruments, public-service standards, and oversight reports. The analysis shows that legal certainty, public interest, impartiality, accuracy, non-abuse of authority, openness, proportionality, professionalism, and accountability must operate as mutually reinforcing standards throughout the service cycle. Bandung has developed digital services, integrated service mechanisms, information disclosure, and complaint channels; However, implementation remains vulnerable to fragmented service standards, unequal digital access, weak feedback loops, and output-oriented accountability. The study proposes an AUPB-based service control model that links published standards, traceable administrative decisions, inclusive access, complaint resolution deadlines, and corrective follow-up. The AUPB model shifts from an abstract ethical reference into measurable legal safeguards for citizens and an internal control framework for municipal agencies.
