<![CDATA[Educational administration in the digital era demands governance transformation through information technology; however, at State Vocational High School (Sekolah Menengah Kejuruan or SMK) Negeri 1 Sukoharjo, which possesses specific administrative complexities such as Field Work Practice (Praktik Kerja Lapangan or PKL) logbook management, comprehensive evaluation of service quality from the end-user perspective is still very minimal, potentially triggering inefficiencies in academic administration. This study aims to evaluate the quality level of the Academic Information System at SMK Negeri 1 Sukoharjo and to identify service attributes that are top priorities for improvement as well as those that need to be maintained. The research method used is descriptive quantitative by adopting the Website Quality 4.0 (WebQual 4.0) instrument, which includes Usability, Information Quality, and Service Interaction Quality dimensions, as well as the Importance Performance Analysis (IPA) method to visualize improvement priorities into a Cartesian quadrant matrix. Research data were gathered through online questionnaires and documentation studies involving stakeholders consisting of students, teachers, and administrative staff, where the minimum sample size determination was calculated using the Slovin formula through the Proportionate Stratified Random Sampling technique. The results of the conformity level analysis and attribute mapping on the Cartesian diagram show an overall level of conformity of 85.36%, with the Usability dimension achieving the best performance, while the Information Quality and Service Interaction Quality dimensions, particularly the PKL data update and helpdesk responsiveness attributes, were identified as top priorities for improvement in Quadrant I. The novelty of this research lies in its multi-stakeholder evaluation (students, teachers, administrative staff) of an Academic Information System at a vocational high school with the unique complexity of PKL logbook management, yielding a structured improvement priority map with concrete recommendations for the development team and school management in efficiently planning budget allocation and system enhancements to optimize overall user satisfaction.]]>
