<![CDATA[The rapid development of information technology has encouraged digital transformation in the religious domain, including the emergence of digital Qur’an applications. Al Quran Indonesia is a widely used application that helps users read and understand the Qur’an practically, however, several issues and user complaints related to system performance and usability constraints are still reported. This study aims to evaluate the usabilitu level of the Al Quran Indonesia application using the System Usability Scale (SUS) method. A quantitive approach was employed, with data collected through a SUS questionnaire consisting of 10 Liker-scale statement. The study involved 100 students from Faculty of Science and Technology at Universitas Jambi as respondents. The data analysis techniques used include individual SUS score calculation, average score determination, and data interpretation base on standard usability criteria ( Adjectival Rating, Grade Scale, and Acceptability Ranges). The result indicate that the application achieved an average SUS score 84,85, which falls into the Best Imaginable (Grade A) category and is considered acceptable. This demonstrates a very good level of usability in terms of effectiveness, efficiency, and user satisfaction, although some minor issues were still identified, such as feature inconsistency and suboptimal system performance. Therefore, the findings are expected to provide valuable insight for developers to continuously improve application quality and user experience.]]>
