Title: Evaluation of the Usability of the Indonesian Qur'an ApplicationAuthor: Shiddiq SeptianaAffiliates: Informatics Engineering Study Program, Faculty of Engineering, Muhadi Setiabudi University Brebes, IndonesiaAbstract:<i> </i><i>This study aims to evaluate the reliability and validity of the construct of the usability measurement instrument which includes the dimensions of efficiency, errors, learnability, memorability, satisfaction, and overall usability. The data analysis methods used included Cronbach's Alpha calculation, Composite Reliability (rho_a and rho_c), and Average Variance Extracted (AVE). The results showed that all dimensions had Cronbach's Alpha values above 0.70 (0.730 - 0.894), indicating good internal consistency. Similarly, the Composite Reliability values (rho_a and rho_c) for all dimensions exceed 0.70 (0.736 – 0.969), indicating strong reliability. Furthermore, the AVE value for the entire dimension is above 0.50 (0.618 - 0.689), indicating adequate convergent validity, where each construct describes a significant variance of its indicators. Overall, these findings confirm that the measurement instruments used are reliable and valid for assessing various aspects of usability, providing a solid basis for further usability studies.</i><br><i>Keywords:</i><b><i> </i></b><i>Usability, Reliability, Validity, Cronbach's Alpha, AVE</i><br><br>
