Fri, 30 Jan 2026 00:00:00 +0700

Rapid population growth and development inequality in West Java Province are challenges for local governments. Therefore, this research develops a development planning Chatbot as a tool to reduce the workload in handling repetitive requests in the regional development planning process in Kuningan Regency as a sample category of areas with low population density. The system is designed using Term Frequency-Inverse Document Frequency (TF-IDF) method to process user messages into numerical matrix, Support Vector Machine (SVM) method to classify user questions automatically, and Streamlit framework for the interface. The developed chatbot is able to generate reports on economic growth trends based on the value of gross regional domestic product at constant prices and business sector recommendations for investors. Chatbot test results in answering valid or correct questions amounted to 60%. Although the accuracy still needs to be improved, this system can still be a useful tool in providing important information for local government decision-making in development planning in low population density districts in West Java.

Comparative Analysis of Deep Learning Barcode Decoding: Evaluating WeChatQRCode vs Pyzbar in Unconstrained Environments

Saepudin Nirwan, Naufal Fachrudin Nirwan — Fri, 30 Jan 2026 00:00:00 +0700

This research introduces a novel hybrid framework integrating YOLO-v5 object detection with Convolutional Neural Network (CNN)-based decoding to address severe visual degradation in unconstrained logistics environments. Compared to standard detection-decoding pipelines (YOLO+Pyzbar) reporting a 91% accuracy rate under general conditions, this study identifies and quantifies the “Cliff Effect” in traditional heuristic algorithms, which exhibit failure once Gaussian noise exceeds the critical threshold of σ=25. In contrast, the implementation of WeChatQRCode demonstrates absolute robustness with a 100% Success Rate and deterministic latency. The novelty of this work lies in proving that neural decoding provides a superior reliability foundation for Industry 4.0 than classic scanline methods under extreme signal degradation.

Muhammad Ruslan Maulani, Andiga Rahman Maulana — Fri, 30 Jan 2026 00:00:00 +0700

Sistem antrian konvensional sering kali menimbulkan penumpukan dan ketidakteraturan, sehingga dibutuhkan solusi digital yang lebih efisien. Penelitian ini merancang dan membangun sistem antrian berbasis IoT menggunakan mikrokontroler ESP32 yang terintegrasi dengan web, guna meningkatkan kinerja dan kenyamanan layanan. Sistem memungkinkan pelanggan mendaftar antrian secara online melalui web maupun secara offline dengan menekan tombol fisik yang terhubung ke ESP32, serta mencetak tiket antrian menggunakan thermal printer. Algoritma FIFO diterapkan untuk memastikan keadilan urutan pelayanan, dan sistem juga mendistribusikan antrian secara otomatis ke dua loket aktif. Web dashboard bagi petugas dilengkapi fitur untuk memanggil, memantau, dan mengelola status antrian secara real time. Pengujian menunjukkan sistem berjalan sesuai fungsinya dan dapat mengatasi permasalahan antrian secara efektif.

Al Khaidar, Sarah Rahmatillah — Fri, 30 Jan 2026 00:00:00 +0700

SMKS Ulumuddin is a vocational high school located in Muara Dua District, Lhokseumawe City, facing challenges in adopting technology to improve the quality of learning in the digital era. As a solution, the development of the Smart School concept can be implemented to integrate information technology into management and learning, allowing students, teachers, and parents to access materials, exams, and learning outcomes online. This study aims to analyze the implementation of The Open Group Architecture Framework (TOGAF) in planning the information technology architecture at SMKS Ulumuddin, specifically to realize the Smart School concept. TOGAF, with its Architecture Development Method (ADM) approach, provides a systematic guide in designing and managing information systems that support the school's vision and mission. Through the stages in TOGAF, such as Architecture Vision, Business Architecture, and Information Systems Architecture, SMKS Ulumuddin can ensure the integration of information technology components efficiently and in line with the educational and operational needs of the school. The implementation of the Smart School concept at this school focuses on the development of information systems that support the learning process, management, and monitoring of student progress. With 13 proposed applications, SMKS Ulumuddin can improve efficiency in managing learning, administration, and school services as a whole. The results of this study can serve as a reference for other schools to strategically adopt technology to support a technology-based modern education vision.
