This research aims to evaluate the level of usability and user satisfaction with the Amikom University Purwokerto student affairs website using the System Usability Scale (SUS) method. This method was chosen because of its simplicity in providing reliable and fast results through a survey based on 10 statements with a Likert scale. The research respondents were active students at Amikom University, Purwokerto, who were selected using a sampling method based on the Slovin formula with a total sample of 97 respondents. Data is collected through an online questionnaire that measures aspects of convenience, satisfaction and system reliability. The analysis results show an average SUS value of 58.85, which is classified in the Marginal Low category based on the interpretation of the SUS scale. These findings indicate that the website has not fully met user expectations in terms of usability, even though it provides relevant features and services. Therefore, improvements are needed in user interface elements, navigation, and design consistency to improve user experience. This research makes an important contribution to the development of information systems in higher education by identifying weaknesses that can be improved to achieve better efficiency and satisfaction.
