"Usability Analysis of Web-Based Global Academic Information Systems (GAIS) Using the System Usability Scale (SUS) Method

Abstrak

Web-based Global Academic Information Systems (GAIS) play a crucial role in
supporting academic administration in higher education institutions. However,
their effectiveness largely depends on the system’s usability. This study aims to
evaluate the usability of the GAIS Academic Information System using the
System Usability Scale (SUS). Data were collected through a questionnaire
distributed to 30 active users of the system. The results indicate that the system
achieved an average SUS score of 72, which is above the standard benchmark of
68[1][5], categorizing it as good in terms of usability. These findings suggest that
the system is generally easy to use and acceptable to users[20]. Nevertheless,
further analysis reveals notable issues related to interface consistency and
navigation efficiency. Therefore, improvements in user interface design and
system structure are recommended to enhance the overall user experience. This
study contributes by providing an empirical usability evaluation and practical
recommendations for improving web-based academic information systems.
