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.

This study aims to analyze the performance of the mailing system information in an expedition company using the Unified Modeling Language (UML) approach. The mailing information system plays a crucial role in the smooth operation of the expedition company, particularly in managing the dispatch and delivery of letters and documents effectively and efficiently. This research uses a descriptive method with a quantitative approach to illustrate and analyze the extent to which the system's performance meets user needs. Data were collected through a questionnaire distributed to 25 respondents, consisting of 17 females and 8 males, to measure three key aspects of the system: user satisfaction, ease of use, and access speed. The results of the study show that the majority of respondents gave very positive assessments of the system. The easeof use aspect received the highest average score (4.4), followed by access speed (4.28) and satisfaction (4.24). However, there are areas that can still be improved, particularly regarding user satisfaction and system access speed for greater optimization. Overall, the study concludes that the mailing information system in the expedition companys functioning well, but the company needs to continue innovating and improving the system's performance to better meet user expectations.

Performance is a performance of the level of success that exists in employees based on the entire process that has been carried out in relation to certain activities during the period determined by the company, especially in the sales sector to achieve turnover for electrical and mechanical products offered to consumers so that further analysis is needed. To further determine the potential performance, use the SWOT method which has 4 parameters such as strengths, weaknesses, opportunities and threats. After carrying out a SWOT analysis, an evaluation of the previously known SWOT conclusions can be determined.
