Abstract

Distribution transformers are crucial components in power distribution systems that require real-time monitoring to prevent disruptions and ensure efficient operation. Internet of Things (IoT)-based monitoring systems offer innovative solutions with the ability to detect disruptions early and provide real-time information to operators. This study proposes an optimized early-detection monitoring system for distribution transformers by utilizing IoT devices, including temperature, pressure, and humidity sensors installed on the transformers to monitor their operational conditions. Data collected through the sensors is then processed using a cloud platform for further analysis, with machine learning algorithms used to detect anomalous patterns indicating potential disruptions. Furthermore, the system is designed to send automatic notifications to operators via a mobile application or web dashboard when a disruption is detected, enabling faster response and prevention of further damage. Test results show that the system is capable of detecting disruptions with high accuracy and can improve maintenance efficiency and reduce transformer operational downtime. The implementation of IoT in distribution transformer monitoring also opens up opportunities for optimizing condition-based maintenance management that is more economical and proactive.

Abstract

This research analyzes the efficiency comparison between the Auxiliary Power Unit (APU) and Ground Power Unit (GPU) on the Airbus A320 aircraft's electrical system during ground operations. Aircraft operations require a stable power supply, provided by either an internal APU or an external GPU. Although the APU offers flexibility, its high fuel consumption and significant environmental impact are considerable concerns. Conversely, the GPU is deemed more efficient and environmentally friendly. The study aims to calculate energy consumption, analyze efficiency, and recommend the most efficient and environmentally sound electrical power source. The method employed is a quasi-experimental field observation, involving direct data collection from a Houchin LTD model C690 GPU unit. Data collection was conducted over 7 days, from June 1 to June 7, 2025. Data analysis includes mathematical calculations for energy efficiency and operational economic analysis. Research findings indicate that the GPU significantly outperforms the APU. The diesel GPU exhibits an energy efficiency of approximately 31.30%, considerably higher than the APU's around 1.54% (based on 7 days of data). The GPU also presents superior electrical power quality, characterized by a higher Power Factor and lower Total Harmonic Distortion (THD). It is recommended that airlines prioritize GPU usage, and airport authorities expand Fixed Electrical Ground Power (FEGP) infrastructure to enhance energy efficiency and reduce operational costs.

Abstract

Switched Reluctance Generators (SRGs) have attracted attention due to their robust construction, low cost, and high fault tolerance, suitable for extreme environments. However, SRGs suffer from torque ripple and acoustic noise due to the non-linear torque-excitation current relationship. Although SRG component optimization has been investigated, a gap exists in the analysis of the effect of stator excitation current on the drive torque in a single-phase "6/6" SRG design with external amplification. This study analyzes the impact of varying stator excitation current on the drive torque of a single-phase 6/6 SRG. The methodology includes design, finite element analysis (FEA), and testing of an initial drive torque prototype. Results show that increasing the stator coil supply voltage results in a greater magnetic force, which counteracts the mechanical torque on the rotor shaft. This understanding is crucial for optimizing torque performance, mitigating ripple, and improving SRG efficiency for future applications.

Abstract

Penelitian ini menganalisis instalasi sistem kelistrikan pada perencanaan pembangunan gedung industri PT. Growth Asia berfokus pada kesenjangan antara prosedur formal dan praktik lapangan. Pasokan listrik yang tidak stabil dan instalasi sementara berisiko tinggi menyebabkan downtime, penurunan produktivitas, dan kecelakaan kerja. Menggunakan metode deskriptif kuantitatif dengan pendekatan studi kasus, penelitian dilaksanakan selama tiga bulan (Juli–September 2025) di Kota Medan. Data dikumpulkan melalui observasi terstruktur, kuesioner, dokumentasi proyek, serta catatan gangguan listrik, dan dianalisis menggunakan statistik deskriptif, uji korelasi Pearson, serta paired sample t-test. Hasil menunjukkan bahwa terdapat kesenjangan antara pemahaman teknisi di lapangan dengan standar teknis isolasi (PUIL/IEC), yang mendorong praktik normalisasi deviasi seperti penyambungan tanpa prosedur standar. Korelasi negatif sedang ditemukan antara kualitas isolasi kabel dan kestabilan sistem listrik (r = -0,574), sementara uji t menunjukkan peningkatan kualitas isolasi secara signifikan menurunkan gangguan kelistrikan (p = 0,00026). Penelitian ini merekomendasikan penguatan pengawasan lapangan dan pelatihan teknis sebagai upaya peningkatan keselamatan kerja dan efisiensi sistem kelistrikan proyek konstruksi.

Abstract

Pembangkit listrik tenaga surya (PLTS) menghasilkan tegangan listrik dari solar cell yang terkena paparan sinar matahari. Tinggi rendahnya tegangan yang dihasilkan adalah tergantung dari banyak sedikitnya sinar matahari yang mengenai panel solar cell. Bayangan yang menutupi solar cell dari sinar matahari secara langsung telah diteliti akan mengakibatkan penuruan tegangan keluaran secara drastis. Panel solar cell yang tertutup tidak akan bekerja sehingga akan mengurangi tegangan keluaran secara keseluruahan pada bagian yang tertutup tersebut. Namun demikian lapisan film yang menutupi panel solar cell tidak menutup cahaya matahari secara keseluruahn, akan tetapi mengurangi unsur sinar matahari yang sampai ke solar cell. Cahaya matahari tetap sampai tetapi unsur panas yang berkurang setelah melewati filter. Memalui penelitian ini diperoleh hasil tegangan akan tetap dihasilkan tetapi terdapat perbedaan dengan hasil paparan matahari secara langsung. Filter yang digunakan tidak hanya mengurangi panas pada solar cell jenis polycrystalline tetapi juga penurunan tegangan keluaran namun tidak terlalu besar. Manfaat tabir ini lebih besar pada penurunan suhu permukaan solar cell.

Abstract

Abstrak. Penelitian ini mengeksplorasi inovasi dan tantangan dalam pengembangan sistem transmisi tenaga listrik berbasis teknologi tinggi, terutama melalui penerapan teknologi Ultra High Voltage (UHV), kabel superkonduktor, dan sistem kontrol cerdas berbasis teknologi informasi dan komunikasi (ICT). Studi ini bertujuan untuk menjawab kebutuhan akan sistem transmisi yang lebih efisien, andal, dan mampu mendukung integrasi energi terbarukan sambil mengurangi dampak lingkungan. Hasil penelitian menunjukkan bahwa teknologi UHV dapat mengurangi kehilangan daya hingga 30%, sementara kabel superkonduktor hampir menghilangkan kehilangan daya pada jarak pendek. Sistem kontrol cerdas berbasis ICT juga meningkatkan stabilitas jaringan dan respons terhadap fluktuasi beban. Namun, implementasi teknologi-teknologi ini masih menghadapi tantangan signifikan, termasuk biaya tinggi, kebutuhan infrastruktur yang kompleks, dan risiko keamanan siber. Penelitian ini menyarankan perlunya kolaborasi lebih lanjut antara industri, pemerintah, dan akademisi untuk mengatasi hambatan tersebut dan mendorong adopsi teknologi transmisi yang lebih luas dan efektif.
