The development of information technology encourages organizations to develop information systems capable of providing user satisfaction. The Information Systems Student Association (ISSA) at the University of Bengkulu still manages administration and finance using Google Drive and basic Google Sheets, resulting in unintegrated archive management, inefficient document search processes, and manual financial recording that is not yet capable of generating automated financial reports. This condition indicates the need for a web-based management information system capable of integrating the management of administrative and financial archives in a structured manner. This study aims to design, develop, evaluate the system's usability, and analyze the effect of usefulness, ease of use, and ease of learning on satisfaction. The usability evaluation involved 148 respondents referring to ISO 9241-11 using the USE Questionnaire to measure users' satisfaction levels. Then, Generalized Structured Component Analysis (GSCA) was used as the method for analyzing relationships between variables. The study results showed a usability level of 86.84%, categorized as excellent. Hypothesis testing indicated that the variables of usefulness and ease of use had a positive and significant effect on satisfaction, whereas the variable of ease of learning does not have a significant effect. The research model also met the goodness of fit criteria with a FIT value of 61%, an AFIT 60.4%, a GFI 99.3%, and a SRMR 0.047.
