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>

摘要：本研究旨在评估可用性测量工具的构念信度与效度，该工具涵盖效率、错误率、易学性、记忆性、满意度及整体可用性六大维度。本研究采用的数据分析方法包括克朗巴哈α系数（Cronbach's Alpha）计算、组合信度（rho_a与rho_c）以及平均变异数萃取量（AVE）。结果显示，所有维度的克朗巴哈α系数值均高于0.70（区间为0.730~0.894），表明内部一致性良好；同理，各维度的组合信度（rho_a与rho_c）值均超过0.70（区间为0.736~0.969），说明信度优异。此外，所有维度的平均变异数萃取量（AVE）值均高于0.50（区间为0.618~0.689），表明收敛效度达标，即各构念均可有效解释其对应指标的显著变异量。综上，本研究结果证实所采用的测量工具具备良好的信效度，可用于评估可用性的各维度，为后续可用性相关研究提供了坚实的基础。
