− The purpose of this research is to analyze the impact of user satisfaction on the Sipenmaru portal at Universitas Muhammadiyah Jambi, addressing common issues such as difficulties in accessing the portal, system overload, and inaccuracies in information. These problems highlight the need for a thorough evaluation of the quality of the system, information, and services provided. By adopting the End-User Computing Satisfaction (EUCS) model and DeLone and McLean's model, this study focuses on identifying factors that influence user satisfaction and how that satisfaction affects the effectiveness of using the Sipenmaru portal. The model includes six main variables: content, accuracy, format, ease of use, timeliness, and user satisfaction, which are integrated with DeLone and McLean's information system success model. As part of the methodology, a questionnaire was distributed to 210 respondents, and the collected data were analyzed using the PLS-SEM method with the help of SmartPLS software. Significant factors influencing user satisfaction include accuracy, format, ease of use, timeliness, information quality, and service quality. To enhance user satisfaction and the effectiveness of using the Sipenmaru portal, it is recommended to optimize the system, improve information quality, and regularly enhance technical services.
