Abstract

Face recognition systems have become increasingly prevalent in various applications, including security, biometric authentication, and digital identity verification. This article presents a comparative study on the implementation and performance of two face recognition methods: Convolutional Neural Network (CNN) and Local Binary Pattern Histogram (LBPH). The research utilized the Labeled Faces in the Wild (LFW) dataset, which comprises 19 classes of faces, with 760 images for training and 475 images for testing. The system was developed using the Python programming language, incorporating TensorFlow/Keras, OpenCV, and Visual Studio Code, along with a Graphical User Interface (GUI). The primary focus of this study was to implement both face recognition methods and analyze the selectivity of the system in distinguishing between known and unknown faces. Experimental results demonstrated that the CNN method offered superior classification stability and consistent face recognition, whereas the LBPH method provided faster training times and reduced computational complexity. Additionally, the results indicated that threshold settings significantly influenced the system’s ability to classify recognized and unknown faces. In conclusion, the study found that CNN is more suitable for applications requiring robust classification capabilities, while LBPH is better suited for lightweight face recognition systems that prioritize processing speed and efficiency.

Abstract

Conventional authentication methods such as passwords and Personal Identification Numbers (PINs) have proven to be vulnerable to misuse and data breaches, highlighting the urgent need for more reliable identity verification systems. Biometric-based authentication, particularly iris recognition, has emerged as a promising solution due to the unique and physiologically stable nature of iris patterns throughout a person's lifetime. However, previous studies in iris recognition have reported limited accuracy and lacked comprehensive evaluation using metrics such as Precision, Recall, and F1-Score. This study designed and implemented an iris recognition system using Gabor Wavelet as the feature extraction method combined with the K-Nearest Neighbor (K-NN) classification algorithm. The dataset was obtained from the CASIA Iris Database, consisting of 100 images covering 20 identity classes, of which 20 images were used as test data. The system pipeline comprised iris segmentation, normalization, feature extraction using Gabor Wavelet, and classification using K-NN with K=1 and Euclidean distance. System performance was evaluated using accuracy, Precision, Recall, and F1-Score metrics across multiple threshold values. The experimental results showed that the proposed system achieved an accuracy of 95%. At a threshold of 0.5, the system produced the best overall performance with a Precision of 0.90, Recall of 0.95, and F1-Score of 0.92. These findings confirmed that the combination of Gabor Wavelet and K-NN was effective for biometric-based iris recognition systems.

Abstract

Teacher performance plays a crucial role in determining the quality of education. However, many schools continue to face challenges related to suboptimal teacher productivity, which may be influenced by leadership and cultural factors within the school environment. This study aims to examine the contribution of principal leadership and school culture to teacher performance. The research employed a quantitative approach using a correlational method. Data were collected from 80 teachers across several schools through structured questionnaires. The variables measured included principal leadership, school culture, and teacher performance. The data were analyzed using descriptive statistics, Pearson correlation, and multiple regression analysis. The results showed that both principal leadership and school culture had a strong and positive correlation with teacher performance, with correlation coefficients of 0.684 and 0.701, respectively. Furthermore, the regression analysis indicated that principal leadership and school culture together contributed significantly to teacher performance, with an R² value of 0.581. Among the two, school culture demonstrated a slightly higher influence than leadership. In conclusion, the findings suggest that enhancing both leadership practices and school culture can significantly improve teacher performance. It is recommended that school management prioritize the development of effective leadership strategies and the cultivation of a positive, collaborative school environment to support teacher growth and performance outcomes

Abstract

Background. The learning process in vocational engineering electronics still faces challenges such as low student literacy, limited face-to-face learning time, and the need for experiment-based instruction. Previous studies have generally examined inquiry-based learning, blended learning, and digital learning separately, with limited integration into a structured Smart Learning–supported instructional model. Smart Learning facilitates digital resources, online discussions, assignment management, and flexible blended learning activities. Purpose. This study aims to develop and validate the Integrated Inquiry Blended Learning (IIBL) model supported by Smart Learning in vocational engineering education. Method. A Design-Based Research approach was employed through iterative processes of analysis, design, development, implementation, and evaluation, including expert validation, practicality testing, and effectiveness testing. Validation instruments were analyzed using SEM-PLS to ensure construct validity, while practicality was measured through student and lecturer perception surveys. Effectiveness was evaluated across three implementation cycles through analyses of cognitive, psychomotor, affective, and 21st-century skills, supported by paired sample t-tests comparing pre- and post-test scores in control and experimental groups. Results. The IIBL model was construct-valid, with outer loadings above 0.70, AVE above 0.50, CR above 0.70, and HTMT below 0.90. Practicality evaluations by lecturers and students reached a very high category, while effectiveness testing showed significant improvements in students’ cognitive, psychomotor, affective, and 21st-century skills. Conclusion. The developed IIBL model provides a validated instructional framework integrating inquiry-based learning, blended learning, and Smart Learning support, contributing a structured IIBL syntax empirically validated through SEM-PLS and demonstrating potential to enhance students’ engagement, practical competencies, and 21st-century skills.
