Abstract

This study implements an Adaptive Extended Kalman Filter (AEKF) for real-time state of charge (SoC) estimation to support charge–discharge regulation in a LiFePO₄ battery system integrated with photovoltaic (PV) generation. Due to the variability of PV output, accurate and stable SoC estimation is essential for ensuring reliable battery operation. A first-order equivalent circuit model (1RC ECM) is employed to represent battery dynamics based on measured current and terminal voltage. The proposed AEKF algorithm is implemented on a Raspberry Pi 5 to enable real-time computation, and the estimated SoC is directly used as the control variable in a dual-relay switching mechanism to regulate charging and discharging processes. Experimental results show that the proposed method achieves a Mean Absolute Error (MAE) of 1.24% and a Root Mean Square Error (RMSE) of 1.58%, which are both below the 5% target specified in the system design. The system successfully maintains the battery within a safe SoC range of 57.5% to 85.2%, while ensuring stable relay operation without chattering under dynamic load and charging conditions. These results demonstrate that the proposed AEKF-based approach provides accurate, stable, and practical SoC estimation, making it suitable for real-time battery management in small-scale energy storage applications.

Abstract

Artificial Intelligence (AI) has become a key enabler of intelligent vehicular (V2X) and Unmanned Aerial Vehicle (UAV) networks. These networks face extreme mobility and rapidly changing topologies, making stable communication and decision-making very difficult. Traditional AI models such as CNN and RNN fail to adapt quickly to these dynamic conditions. This survey reviews recent AI-based approaches designed to improve reliability, latency, and energy efficiency in V2X and UAV networks. The study compares Deep Reinforcement Learning (DRL), Graph Neural Networks (GNN), and Federated Learning (FL) methods, highlighting their benefits and limitations. Future research should focus on adaptive AI architectures that can operate under continuous topology changes and mobility uncertainty.

Abstract

Indonesia's electricity needs are still heavily dependent on fossil fuels, necessitating the development of more environmentally friendly alternative energy sources. One potential solution is the use of rooftop solar power plants (PLTS). This research aims to design an on-grid rooftop solar power system for the Integrated Lecture Building (SBSN) at Khairun University. The research phase involved collecting data on the building's electricity consumption, potential solar radiation at the site, and calculating the system design based on module capacity, number of panels, and performance ratio (PR). The analysis revealed that an installed capacity of 40 KWP can generate 52,560 kWh of electricity per year. Compared to the building's total annual electricity demand of 266,400 kWh, this PLTS contributes 19.7%. The economic analysis also indicates potential savings of approximately Rp 3.22 million per month or Rp 38.67 million per year in electricity costs. Therefore, the implementation of rooftop solar power plants is considered a viable renewable energy solution to reduce electricity costs while supporting the implementation of clean energy on campus.

Abstract

Class-D audio power amplifiers deliver high operational efficiency but remain highly susceptible to catastrophic failures induced by thermal runaway and overcurrent events. Conventional protection mechanisms, such as passive fuses, typically exhibit delayed response times and lack the capability to record historical diagnostic data. This study designs and implements an active, intelligent protection framework driven by an Arduino Nano microcontroller and a Python-based interface. The methodology integrates an LM35 thermal sensor and an INA219 digital current monitor, strictly validated through a one-point calibration procedure and enhanced by a hybrid filtering technique to eliminate signal noise. A digital OR logic gate algorithm is applied to execute rapid decision-making. Experimental results demonstrate exceptional measurement precision, achieving an average relative error of only 0.43% for temperature and 1.16% for current. The logic-based actuator successfully and instantaneously disconnected the power load during simulated fault conditions whenever the predefined safety thresholds (60°C or 2.0 A) were exceeded. Furthermore, the integrated data logger effectively captured real-time failure telemetry for post-incident evaluation. In conclusion, the proposed digital logic framework provides a highly responsive, data-driven, and superior preventive alternative to traditional passive audio amplifier protection.

Abstract

Meningkatnya permintaan akan sistem deteksi jatuh yang andal dalam pemantauan perawatan pasien sekaligus membantu lingkungan kehidupan mendorong pengembangan model visi komputer yang mampu mengidentifikasi kejadian jatuh secara akurat dalam kondisi dunia nyata. Sistem ini harus mendeteksi perubahan postur tubuh manusia di berbagai posisi sambil mempertahankan ketahanan terhadap latar belakang yang kompleks, yang seringkali mengurangi akurasi deteksi. Selain itu, penerapan di dunia nyata membutuhkan model yang beroperasi secara efisien pada perangkat berbiaya rendah dan memproses aliran video langsung secara real-time. Studi ini menganalisis efektivitas peningkatan versi nano dari arsitektur YOLOv12 untuk deteksi jatuh dengan mengintegrasikan mekanisme ONA-Net. Modul yang diusulkan memungkinkan jaringan untuk fokus pada beberapa respons penting yang terkait dengan postur tubuh manusia, memungkinkan model untuk menangkap isyarat spasial yang terkait dengan kejadian jatuh dengan lebih baik. Desain yang ringan mengurangi beban komputasi sambil mempertahankan ekstraksi fitur yang efektif untuk deteksi yang akurat. Temuan eksperimental menunjukkan YOLOv12-ONA-Net sebagai model yang diperkenalkan memperoleh kinerja deteksi yang kuat, dengan memperoleh 92,3% mAP@50 dan 59,7% mAP@50:95. Meskipun arsitekturnya ringan, model ini tetap mempertahankan efisiensi praktis dengan mencapai kecepatan inferensi 13,13 frame per detik (FPS). Hasil ini menunjukkan bahwa penggabungan ONA-Net ke dalam jaringan YOLOv12n meningkatkan kemampuan deteksi jatuh sekaligus mempertahankan penggunaan komputasi yang sesuai untuk penggunaan pemantauan waktu nyata pada perangkat dengan kapasitas komputasi terbatas.

Abstract

Violence against women and children constitutes a serious and escalating social problem; however, reporting rates remain critically low due to the absence of safe, accessible, and confidential reporting mechanisms. This study aimed to develop a web-based violence reporting application for the SP Sambe Women’s School (Sekolah Perempuan/SP) community in Tiley Pantai Village, Morotai Island Regency. The application was developed using the waterfall software development model, which encompasses four sequential phases: requirements analysis, system design, development, and testing. Data were collected through structured observation and in-depth interviews with prospective end-users. The results indicate that the application’s core features include anonymous incident reporting, report tracking via unique system-generated codes, role-specific dashboards for administrators and officers, and a case follow-up management module. Black-box testing confirmed that all implemented features functioned in accordance with the specified requirements. The application is expected to facilitate rapid, secure, and confidential reporting for community members, while simultaneously improving the efficiency of case management and administrative oversight for the SP Sambe community. This study affirms that the strategic utilisation of information technology can meaningfully contribute to the resolution of complex social problems, particularly those pertaining to violence against women and children.
