Abstract

This study investigates the effectiveness of Qur’anic teachers in delivering instruction to learners across various age groups within formal Islamic educational institutions. The research is motivated by the absence of standardized professional criteria for Qur’anic educators, which has contributed to inconsistent teaching practices, instructional challenges, and varying interpretive outcomes among students. The study aims to (1) identify the key factors that influence Qur’anic teachers’ performance and (2) explore the strategies implemented by school leaders to enhance instructional quality. Using a qualitative design, data were gathered through interviews, classroom observations, and document analysis involving Qur’anic teachers, students, and institutional administrators. The credibility of the data was strengthened through prolonged engagement, persistent observation, and methodological triangulation. The findings indicate that effective Qur’anic teaching performance is demonstrated through strong content mastery, the application of appropriate pedagogical strategies, and the ability to address students’ inquiries using reliable scholarly sources. The study highlights the importance of clearly defined performance standards and targeted professional development initiatives in enhancing the overall quality of Qur’anic education.

Abstract

The ripeness level of bananas is a crucial factor that affects the quality, taste, and selling value of the commodity, but the manual sorting process that is commonly carried out is still subjective, inconsistent, and time-consuming. This study aims to implement and evaluate the performance of a VGG16-based Convolutional Neural Network (CNN) architecture in automatically classifying the ripeness level of bananas. The research dataset consists of 5,616 digital images obtained from the Roboflow Universe platform and grouped into six specific classes: freshripe, freshunripe, overripe, ripe, rotten, and unripe. The system development methodology includes data division using stratified splitting techniques, image pre-processing with data augmentation strategies to prevent overfitting, and the application of transfer learning. The model was trained using the Stochastic Gradient Descent (SGD) optimization algorithm with a learning rate of 0.001 for 25 epochs on GPU-based hardware. Performance evaluation was conducted in depth using a confusion matrix, F1-Score metrics, and Precision-Recall curve analysis. The experimental results showed that the VGG16 model achieved an overall accuracy of 97.13%. Class-by-class analysis shows perfect performance in the freshunripe category, although there is a slight decrease in precision in the ripe class due to the similarity of visual characteristics with the overripe class. The stability of the training and validation accuracy curves also indicates that the model has good generalization capabilities. This study concludes that the VGG16 architecture is a reliable and accurate solution to support the efficiency of smart farming systems.
