A COMPARATIVE ANALYSIS OF MACHINE LEARNING ALGORITHMS AND USER EXPERIENCE FOR ACADEMIC PERFORMANCE PREDICTION

Tasril, Virdyra, Prayudani, Santi, Prayoga, J., Mayang Sari, Rahayu
Abstract: This study aimed to compare the performance of machine learning algorithms and user experience in predicting students’ academic achievement. The research is motivated by the need for prediction systems that are not only… y highly accurate but also easily interpretable by users. The proposed methodology involved the implementation of two algorithms, namely Decision Tree and Random Forest, using an academic dataset that included grade point average, attendance, and assessment scores. Model performance was evaluated using accuracy, precision, recall, and F1-score, while user experience was assessed through the System Usability Scale (SUS) based on a simple user interface. The findings revealed that Random Forest achieved higher predictive accuracy, whereas Decision Tree provided better interpretability and ease of understanding for users. These results indicated a trade-off between model performance and user experience, suggesting that algorithm selection should consider both aspects in order to develop an effective and user-friendly academic prediction system

Effendi, Diana, Dhaniawaty, Rani Puspita, Hidayat, Rahmat, Alghani, Muhammad
Abstract: Abstract: Mosques are places of jamaah and centers of social and economic activity for Muslims. Still, in the process of managing their activities, DKM administrators often face challenges related to efficiency, integration,… ion, and transparency of information. This research aims to develop a web-based Mosque Management Information System (SIMMAS) that integrates the management of ZISWAF (zakat, infaq, sadaqah, waqf), qurban, inventory, activity information, and digital payments via QRIS. Using the Rapid Application Development (RAD) method, the system was designed to be developed quickly and in alignment with user needs. The evaluation was conducted using the Customer Satisfaction Index (CSI) approach, involving 60 respondents comprising mosque administrators and congregants. The results show that all SIMMAS services received CSI scores above 85%, indicating a high level of user satisfaction, particularly with the religious lecture scheduling feature. Nevertheless, there remains room for improvement, especially in the responsiveness and empathy aspects of financial and inventory services. This research is expected to serve as a foundation for the continued development of SIMMAS to become more effective, efficient, and digitally integrated in mosque management.   Keywords: user satisfaction; mosque information system; CSI; SIMMAS; ZISWAF   Abstrak: Masjid merupakan tempat ibadah, pusat aktivitas sosial dan ekonomi umat Islam, namun dalam proses pengelolaan kegiatannya, pengurus dkm kerap menghadapi tantangan terkait efisiensi, integrasi, dan transparansi informasi Penelitian ini bertujuan untuk mengembangkan Sistem Informasi Manajemen Masjid (SIMMAS) berbasis web yang mengintegrasikan pengelolaan ZISWAF, qurban, inventaris barang, informasi kegiatan, serta pembayaran digital melalui QRIS.

ANALYSIS OF THE QUALITY OF "ONLINE EQUIVALENT" E-LEARNING USING WEBQUAL 4.0 AND IPA METHODS

Rahman, Taufik, Azizah, Alfi
Abstract: Abstract: The use of e-learning in non-formal education is increasingly important to support the improvement of access to learning, one of which is through the online platform. This study aims to analyze the quality of online… nline services using WebQual 4.0 and Im-portance Performance Analysis (IPA) methods to evaluate the suitability between user expectations and perceptions. The research method used a quantitative approach by distributing questionnaires to active users, then analyzed using the WebQual Index to measure the overall quality of the system as well as the IPA to determine improvement priorities. The results showed that the quality of SeTARA Online was relatively good with a WebQual Index value of 0.798. However, there is still a gap between user expectations and satisfaction with a negative gap value of -0.238. The IPA analysis identified indicators in Quadrant I as priority improvements, especially in the aspects of service interaction and information presentation. These findings underscore the need for continuous development of features and technical support to optimize the user experience. The conclusion of this study suggests that there should be improvements in priority indicators to increase user satisfaction, as well as strengthen the effectiveness of online learning. Advanced research can expand variables, compare with other platforms, and combine quantitative and qualitative analysis methods for more comprehensive results.   Keywords: e-learning; importance performance analysis; quality of service; online equivalent; webqual 4.0
