Abstract

This study aims to evaluate the usability level of a university website using the System Usability Scale (SUS) method, with a case study conducted on the website of Universitas Narotama, which can be accessed at https://narotama.ac.id. Data were collected through a questionnaire distributed to 50 respondents who had prior experience using the website. The SUS instrument consists of 10 statements measured using a five-point Likert scale. The collected data were analyzed by calculating the SUS score based on standard procedures.
The results indicate that the website achieved a SUS score of 72.75, which falls into the “Good” category and suggests that the system is acceptable to users. Further analysis reveals that users generally perceive the website as easy to use and learn; however, several aspects such as navigation structure, interface consistency, and information clarity still require improvement.
These findings suggest that although the website has met basic usability standards, further optimization is necessary to enhance the overall user experience. This study provides practical recommendations for improving the quality and development of more user-friendly websites.
