Abstract

The Computer-Based Testing (CBT) application plays a significant role in supporting the learning evaluation process in the modern era. As a technology- based tool, this application enables examinations to be conducted more efficiently, quickly, and in a more structured manner compared to conventional paper-based methods. SMA Negeri 1 Semendawai Barat is a state senior high school located in Kangkung Village, Semendawai Barat Sub-district, Ogan Komering Ulu Timur Regency, South Sumatra Province. The school has implemented information and communication technology (ICT) in its teaching and learning activities, including the administration of examinations through the use of the Bravo Computer-Based Testing (CBT) application to improve the quality of academic evaluations. The use of the Bravo CBT application reflects the school's commitment to keeping pace with developments in educational technology. One method that can be used to evaluate the effectiveness of such applications is WebQual, which is an enhancement of the Servqual method a tool that has long been used in evaluating service quality. WebQual has been adapted specifically to measure the quality of applications or websites through three main dimensions: usability, information quality, and service interaction. Research findings indicate that the variables Usability and Information Quality do not have a significant effect on Service Quality, whereas the Service Interaction Quality variable does have a significant impact on Service Quality.

Abstract

A facial recognition-based attendance system is a modern solution to overcome the weaknesses of manual attendance methods that are prone to manipulation and recording errors. This study uses a deep learning-based attendance application by implementing a Convolutional Neural Network (CNN) using MobileNetV2, VGG16, and ResNet50 architectures optimized for devices with limited resources. The facial dataset was collected independently and went through preprocessing stages, including normalization, resizing, augmentation, and face detection with OpenCV. The model was trained using TensorFlow and Keras on Google Colab with a GPU. It was then evaluated using a confusion matrix, which yielded accurate predictions with a low error rate. A classification report was also conducted, with an accuracy of 0.98, a precision of 1.00, a recall of 1.00, and an F1-score of 1.00, achieving a very high level of performance, indicating no prediction errors. A Flask web-based application was designed to connect the facial recognition model with the user interface, and was tested in real-time to measure the speed and accuracy of attendance. The results show that the CNN-based attendance application is able to provide a safer, faster, and more efficient attendance alternative compared to conventional methods.
