Abstract

Student learning concentration is one of the key factors influencing academic achievement and the effectiveness of the learning process. However, monitoring students' concentration levels manually is often subjective and challenging, especially in classrooms with a large number of students. This study aims to implement a Convolutional Neural Network (CNN) model for facial expression detection to classify the learning concentration levels of Senior High School (SMA) students. The research employs a quantitative experimental approach using facial image datasets collected during classroom learning activities. The dataset undergoes several preprocessing stages, including face detection, cropping, image resizing, and pixel normalization before being used for model training. The CNN architecture is designed to automatically extract facial features and classify students' concentration levels into three categories: high, medium, and low concentration. Model performance is evaluated using accuracy, precision, recall, and F1-score metrics. The experimental results indicate that the CNN model is capable of recognizing facial expression patterns related to learning concentration effectively and achieving high classification performance. Furthermore, the developed system provides a more objective and efficient approach for monitoring student concentration compared to conventional observation methods. Therefore, the implementation of CNN-based facial expression recognition has significant potential to support intelligent educational systems and improve learning evaluation processes in school environments.

Abstract

A routine activity carried out by students and teachers before the teaching and learning process is attendance. Attendance is one of the important components used as a benchmark for assessing attendance and performance. Attendance activities, especially in schools, tend to still use manual methods. So there are still frequent errors in recapitulation and recording of attendance. One of the microcontroller components that supports attendance activities is the ESP 32 Cam. Therefore, research was conducted to create an effective and easy-to-use attendance system based on the ESP 32 Cam. The ESP 32 Cam has the advantage of being equipped with a camera and wifi so that teachers who will take attendance are required to record facial images. This minimizes the occurrence of fraud in the attendance process. Furthermore, the Firebase Database functions as a storage place for teacher attendance data. Firebase Database is a service that provides a cloud-based data storage application in JSON format. In addition, Firebase Database also has the advantage of real-time data synchronization. After conducting research, the ESP32 Cam is not equipped with a good operating system for managing system files. Therefore, the author tried to conduct research by developing a teacher attendance system with the ESP 32 Cam and Firebase Database. The attendance process begins with the administrator registering or recording a facial image. The attendance process is then carried out by bringing the face close to the ESP 32 Cam camera. The identified facial recording is then sent and stored in the Firebase Database. The results of this study indicate that the attendance system can only be used by teachers who have previously registered and only covers teachers at one school.

Abstract

This study aims to develop an integrative model based on data mining and machine learning to analyze purchasing patterns and predict consumer product sales at CV. Mitra Ridge. The approach used combines the FP-Growth algorithm to discover product association patterns (frequent itemsets and association rules), XGBoost as a gradient boosting-based sales prediction model, and SHAP (SHapley Additive Explanations) to provide transparent interpretability of the model's prediction results. The data used is sales transaction data from October 2024 to September 2025, which includes 500 transactions with various types of consumer products. The results show that the integration of association pattern features from FP-Growth as additional input to the XGBoost model can improve prediction accuracy compared to a single XGBoost model without integration. SHAP analysis revealed that purchase frequency, product category, and product combination patterns are the most influential factors in sales prediction. This integrative model is proven to be superior in performance and provides deeper business insights, so it can be used as an operational decision support system in stock management, bundling strategies, and data-driven marketing planning in consumer retail companies.

Abstract

Examination timetabling in vocational higher education is a combinatorial optimization problem involving courses, students, invigilators, classrooms, laboratories, and time slots. At AMIK Medicom, the schedule preparation process is still semi-manual, which may cause student conflicts, room conflicts, unbalanced invigilator assignments, and poor exam distribution. This study aims to design an examination timetabling optimization model by integrating Linear Programming (LP) and Simulated Annealing (SA). LP is used to formulate hard constraints to ensure schedule feasibility, while SA is applied to improve schedule quality based on soft constraints, such as exam spread and room utilization. The dataset consists of 29 lecturers, student data from academic years 2021/2022 to 2024/2025, and curricula from three study programs with 154 courses in total. The proposed design shows that the model can transform the examination timetabling problem into structured decision variables, objective functions, and mathematical constraints. In the prototype testing scenario, the LP-SA approach is directed to produce a timetable with zero hard-constraint conflicts and lower soft-constraint penalties compared with semi-manual preparation. The model can serve as a basis for developing a web-based automatic examination scheduling system to improve academic administrative efficiency at AMIK Medicom.
