This research analyzes the performance of the Academic Information System (SIAKAD) in supporting student tuition payments at STMIK Widuri using the PIECES method (Performance, Information, Economy, Control, Efficiency, Service). SIAKAD aims to streamline academic administration and enable online payments. However, issues such as system access delays, especially near payment deadlines, still occur, negatively impacting students' academic services and resulting in administrative penalties. The study employed data collection techniques through observation, interviews, questionnaires, and literature review. The PIECES framework was applied to evaluate six key indicators: performance, information, economy, control, efficiency, and service. The findings reveal that all indicators achieved an average score above 3.80, indicating a "good" system performance. Nonetheless, further improvements are necessary, particularly in terms of access speed and data security, to minimize user difficulties. The study concludes that optimizing the SIAKAD system is crucial for achieving effective and efficient payment processes. Recommendations include enhancing service quality, improving information accuracy, and strengthening data security. This optimization is expected to increase user satisfaction and support the institution's financial management stability.

Grha Kedoya Hospital in West Jakarta faces significant challenges in document management, including medical records, financial reports, and administrative documents. This study aims to analyze the document storage system in the Secretariat Unit of Grha Kedoya Hospital using the User Acceptance Testing (UAT) method. The results show that the security, functional, and non-functional aspects of the document storage system are rated very well by respondents, with average scores of 80.4%, 81.4%, and 76.4% respectively. Despite challenges in transitioning to a digital system such as staff adaptation and infrastructure investment, the majority of respondents support this change to enhance efficiency and security. The UAT method proves effective in identifying the system's strengths and weaknesses, providing constructive feedback for improvement.
