Abstract

In the evolving landscape of digital education, Learning Management Systems (LMS) have become pivotal in managing student engagement and academic resources. These platforms not only facilitate course delivery but also log extensive behavioral data, including attendance rates, quiz performances, LMS usage time, and forum activities. Leveraging this data, educators and institutions can enhance academic outcomes through predictive analytics. This study investigates the use of Random Forest Regression, a machine learning technique, to predict student final grades based on LMS behavioral data. A synthetic dataset comprising 100 student records was used, each containing features that reflect engagement and performance. The data underwent standard preprocessing procedures including normalization and partitioning into training and testing sets. The Random Forest model was trained and evaluated using Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE) as performance metrics. The model achieved a MAE of 4.57 and RMSE of 5.90, indicating a high level of predictive accuracy. Feature importance analysis revealed that average quiz score and attendance rate were the most significant predictors, followed by LMS time and forum activity. These findings demonstrate the effectiveness of ensemble learning methods in educational settings and support the integration of predictive systems in LMS platforms for real-time academic monitoring. Such systems could provide early alerts for at-risk students and assist educators in designing targeted interventions. This research contributes to the field of Educational Data Mining by validating the practical utility of Random Forest Regression in supporting personalized and data-driven learning strategies.

Abstract

The rapid evolution of 5G networks has unlocked new capabilities for the Industrial Internet of Things (IIoT), enabling ultra-reliable, low-latency, and scalable communication. However, challenges such as dynamic resource allocation, network congestion, and growing cybersecurity threats continue to limit the full potential of 5G-IIoT integration. Building upon previous literature, this paper proposes a novel architectural framework that combines artificial intelligence (AI) for intelligent network optimization and blockchain technology for decentralized, secure data management.The framework introduces a layered system comprising four integrated components: AI-driven resource management, a permissioned blockchain layer for secure authentication, an edge-cloud coordination module for low-latency computing, and a network slicing orchestrator for application-specific service differentiation. Each component is designed to address specific limitations in existing 5G-IIoT deployments by enhancing adaptability, reducing security risks, and optimizing performance.This paper outlines the architectural design, data flow, and interaction between components. It also defines the evaluation metrics and simulation setup for benchmarking the proposed framework against conventional 5G-IIoT systems. Preliminary findings and existing literature suggest that integrating AI and blockchain mechanisms can significantly improve latency, throughput, energy efficiency, and security resilience.This work aims to serve as a foundational blueprint for building intelligent, secure, and future-ready IIoT infrastructures powered by 5G. Future work will focus on simulation, real-world deployment, and integration with upcoming 6G paradigms.

Abstract

Cyber-Physical Systems (CPS) are increasingly deployed across sectors such as energy, manufacturing, and healthcare, where real-time monitoring and secure operations are essential. As these systems become targets for sophisticated cyber threats, the need for accurate, low-latency intrusion detection has become critical. While many studies have proposed AI-based solutions for securing CPS, there remains a lack of systematic benchmarking across diverse datasets and attack scenarios.This paper presents a dataset-driven benchmarking study of machine learning and deep learning-based Intrusion Detection Systems (IDS) tailored for CPS environments. Using publicly available CPS-related datasets—including UNSW-NB15, CICIDS2017, BATADAL, and the ICS-Cyber Attack Dataset—we evaluate the performance of Support Vector Machines (SVM), Random Forest (RF), Long Short-Term Memory (LSTM) networks, and a proposed Hybrid AI model. Evaluation metrics include accuracy, precision, recall, F1-score, and false positive rate, providing a holistic view of each model's effectiveness. Results indicate that while traditional models like RF and SVM offer faster inference times, deep learning models such as LSTM consistently outperform in terms of detection accuracy and false positive reduction. The Hybrid AI model demonstrates a balanced trade-off between performance and efficiency, making it a promising approach for real-world CPS deployments. This benchmarking effort serves as a foundation for selecting and optimizing IDS solutions in CPS, highlighting the importance of aligning detection models with dataset characteristics and operational constraints.

Abstract

The use of artificial intelligence (AI) technology is growing rapidly in various sectors, including public services. One of the main challenges in digital public services is how to provide answers that are fast, accurate, and easy for the public to understand. Natural Language Processing (NLP) is key in the development of automated question-and-answer systems. This study evaluates and optimizes the use of ChatGPT as an NLP model in a question-and-answer-based public service system. The methods used include literature review, system design, prototype implementation, and performance evaluation based on accuracy, response speed, and user satisfaction. The results show that ChatGPT can increase answer accuracy by up to 88%, reduce the average response time to 2.9 seconds, and increase user satisfaction to 85%. The system is also able to adapt its language style to make it more understandable to the public. These findings indicate that ChatGPT can be effectively integrated into digital public services, with important considerations regarding ethics, data security, and bias mitigation.

Abstract

Violence against children in Indonesia remains a crucial issue that requires a data-driven approach for more targeted interventions. This study aims to cluster provinces in Indonesia based on the number of cases of violence and the types of violence committed, namely physical, psychological, and sexual violence. The method used in this study is the K-Means Clustering algorithm, an unsupervised learning technique in data mining that is able to find hidden patterns in large data sets. Data was obtained from the Ministry of Women's Empowerment and Child Protection's Gender and Child Information System (SIGA), which covers 38 provinces. The clustering results produced three main groups: a cluster with high levels of violence consisting of the provinces of North Sumatra, DKI Jakarta, West Java, Central Java, and East Java; a cluster with moderate levels of violence consisting of 16 provinces; and a cluster with low levels of violence covering 17 provinces. These findings are expected to form the basis for the development of evidence-based child protection policies geographically and thematically.

Abstract

This paper presents a dual-band frequency reconfigurable microstrip antenna integrated with an Electromagnetic Band Gap (EBG) structure for modern wireless communication applications. The proposed antenna operates at two key frequency bands of 1.8 GHz and 2.4 GHz and is fabricated on a Rogers 4003C substrate to achieve low dielectric loss and stable radiation performance. Frequency reconfigurability is achieved by embedding varactor diodes across strategically etched slots on the radiating patch, allowing continuous tuning through DC bias voltage control without altering the physical structure of the antenna. The EBG structure is employed to suppress surface wave propagation and enhance antenna gain and radiation stability. Simulation and experimental results demonstrate effective frequency tuning from 1.68–1.88 GHz and 2.38–2.81 GHz with stable impedance matching and directional radiation patterns. The proposed antenna is suitable for compact and reconfigurable wireless systems such as IoT and 5G applications.

Abstract

This paper presents the design and analysis of metasurfaces for surface-based wireless communication systems. Metasurfaces are widely used as reflecting or transmitting surfaces in wireless communications. The reflection phase characteristic of a metasurface plays an important role in determining its operating behavior, namely whether it functions as a reflector or a transmitter. In this work, a comprehensive analysis is conducted to obtain two distinct reflection phase characteristics of metasurface unit cells. The unit cells are analyzed at an operating frequency of 3.5 GHz. It is observed that the unit cell exhibits a reflection phase close to 0° when designed using two rectangular rings, while a reflection phase close to 180° is achieved when the unit cell is modeled as a square ring. In both designs, the unit-cell substrate size is fixed at 16.25 × 16.25 mm². The presented reflection phase characterization provides a clear design guideline for selecting metasurface unit-cell geometries to support reflection and transmission functionalities in future surface-based wireless communication systems.

Abstract

This work focuses on refining the radiation pattern of a dipole antenna by introducing a parasitic element and carefully adjusting its size and position. A dual‑band response emerges when the parasitic element is set to a width of 9 mm. The study explores dimensions of 0.98 Wh, 0.90 Wh, 0.70 Wh, and 0.75 Wh. For the first three cases, the element is placed 9.4 mm away from the dipole antenna. In the 0.75 Wh case, however, the spacing is increased to 11.8 mm, which produces a clear improvement in gain. These results show how subtle changes in geometry and placement can significantly influence antenna performance, offering a straightforward path to achieving dual‑band operation with enhanced radiation characteristics.
