Abstract

Pembangkit Listrik Nano Hidro (PLNH) adalah teknologi yang memanfaatkan energi kinetik aliran air untuk menghasilkan listrik. Penelitian ini bertujuan untuk menganalisis kinerja turbin dalam PLNH dengan memvariasikan debit air yang masuk ke sistem. Data yang diukur meliputi kecepatan putaran (RPM), tegangan listrik (Volt), arus listrik (Ampere), dan daya listrik (Watt). Hasil penelitian menunjukkan bahwa penurunan debit air secara signifikan mempengaruhi keempat parameter tersebut. Ketika debit air berkurang dari 0.9 L/s menjadi 0.18 L/s, terjadi penurunan pada RPM dari 445 menjadi 136, tegangan dari 4.32 V menjadi 1.29 V, arus dari 1.22 A menjadi 0.28 A, dan daya dari 1.4884 W menjadi 0.084 W. Hal ini menunjukkan bahwa debit air merupakan faktor utama yang menentukan efisiensi dan output listrik dari PLNH. Penelitian ini mengindikasikan potensi PLNH sebagai sumber energi alternatif yang efisien dan ramah lingkungan, terutama di daerah-daerah terpencil dengan akses terbatas pada sumber energi konvensional

Abstract

The impact of installing a capacitor bank on the performance of an electrical system is evaluated through the analysis of changes in active power, reactive power, voltage, and power factors at various buses. The analysis indicates that the addition of the capacitor bank results in a significant increase in active power and a substantial reduction in reactive power. At Bus 1 (20 kV), active power increased from 648.93 kW to 687.38 kW, while reactive power decreased from 613.19 kVAR to 124.24 kVAR. At Bus 2 (0.4 kV), active power from 635.65 kW to 679.25 kW, and reactive power dropped from 560.59 kVAR to 92.046 kVAR. Voltage levels remained stable or slightly increased, and the power factor showed significant improvement, rising from 72.684% to 98.046% on Bus 1 and from 75.000% to 99.094% at Bus 2. Overall, the capacitor bank enhances system efficiency by optimizing power usage and reducing reactive power.

Abstract

Pembangkit Listrik Tenaga Pico Hydro (PLTPH) merupakan solusi efisien untuk penyediaan energi terbarukan di daerah dengan sumber daya air terbatas. Penelitian ini mengevaluasi kinerja PLTPH dengan kapasitas 5 kW di Desa Cintaraja, fokus pada pengukuran kecepatan aliran, debit air, serta daya dan arus generator sepanjang tahun. Analisis menunjukkan bahwa meskipun PLTPH beroperasi dengan efisiensi tinggi dan penetrasi energi terbarukan melebihi 100% di sebagian besar bulan, terdapat fluktuasi signifikan dalam output daya, terutama pada bulan-bulan dengan debit air rendah seperti Juli dan Agustus. Penurunan output daya ini menandakan ketergantungan pada sumber energi eksternal seperti PLN untuk memenuhi kebutuhan listrik desa. Faktor kapasitas hidro generator tercatat sebesar 126%, dengan biaya pembangkitan rata-rata (LCOE) sebesar 2.232 Rp/kWh, mencerminkan efisiensi ekonomi yang baik.Dimana Hasil yang didapatkan menunjukkan bahwa potensi PLTPH dalam menyediakan energi terbarukan yang andal sangat tinggi.

Abstract

In the industrial sector, the widespread use of non-linear loads such as inverters and variable speed drives has led to increased harmonic distortion, which negatively impacts power quality. These harmonics can cause equipment malfunctions, overheating, reduced system efficiency, and potential failures in power infrastructure. This study aims to optimize the design of a Single-Tuned Passive Filter (STPF) using the Particle Swarm Optimization (PSO) algorithm to minimize harmonic distortion in industrial electrical systems. Harmonic measurements in a representative system revealed Total Harmonic Distortion of current (THDi) values of 20.2%, 20.3%, and 18.6% for phases L1, L2, and L3, respectively, with the 5th and 7th harmonic orders being the most dominant. Initial simulation using standard filtering reduced THDi to 3.03%, 3.10%, and 2.89%, but significant residual harmonics were still present. By applying a PSO-optimized STPF, the THDi was further reduced to 2.42%, 2.43%, and 2.23%, indicating a marked improvement in harmonic mitigation. These findings confirm that the PSO-based design approach effectively enhances filter performance, resulting in improved power quality, increased system reliability, and better protection of electrical equipment. The implementation of the optimized STPF is particularly valuable in industrial environments such as the automotive sector, where power stability and equipment longevity are critical.

Abstract

Electric power distribution to consumers requires periodic preventive maintenance, including thermal inspection of electrical components. An efficient maintenance strategy can save an industry from potential hazards and devastating losses. Therefore, monitoring the temperature of electrical components is crucial to prevent excessive heat that can lead to fires. This research aims to analyze the detection of electrical component damage in consumer distribution networks using IR Thermography for consumer electric network maintenance. The method involves capturing thermal images of targeted hotspots in various components within the consumer distribution substation. The observed components include transformer 2500 kVA connections, connections in the Low Voltage Main Distribution Panle (LVMDP), connections in the Capacitor Bank, and the Panel Change Over Switch (COS). The acquired data is then processed using Smart View software for analysis, categorization, and recommendations. The results reveal the highest temperatures recorded were 91.0°C in the transformer 2500 kVA, specifically in Phase R, and 71.8°C in the LVMDP panel, in Phase T. These findings indicate that the main causes of temperature rise are load imbalance in the transformer and connection failure in the breaker junction.

Abstract

Teknologi mekatronika merupakan integrasi dari mekanika, elektronika, kontrol, dan sistem informasi yang berperan penting dalam industri modern. Dengan mekatronika, sistem otomatisasi dapat dikembangkan secara efisien, meningkatkan produktivitas dan kualitas produk di berbagai sektor, seperti manufaktur, pertanian, dan kesehatan. Contoh aplikasi mekatronika mencakup lengan robot dan mesin bubut yang mengunakan kontrol numerik, yang dapat menjalankan tugas kompleks dengan program yang dapat disesuaikan.Meskipun potensi mekatronika tinggi, pemahaman dan penerapannya di masyarakat, terutama di daerah pedesaan, masih rendah. Program pengabdian masyarakat ini bertujuan untuk memperkenalkan teknik mekatronika kepada siswa, guru, dan pemuda melalui pelatihan dan workshop, sehingga mereka dapat memahami prinsip dasar dan penerapan mekatronika dalam kehidupan sehari-hari serta usaha kecil. Universitas Mayasari Bakti di Tasikmalaya telah menghasilkan inovasi, seperti sistem Motor Operated Valve (MOV) untuk penyiraman tanaman dan pemantauan inkubator telur bebek berbasis IoT. Kolaborasi dengan SMK Igasar Pindad bertujuan untuk meningkatkan pemahaman mekatronika, memberikan manfaat bagi masyarakat, dan memperkuat kompetensi dalam menghadapi era industri 4.0.

Abstract

Inverter-based Heating, Ventilation, and Air Conditioning (HVAC) systems are increasingly utilized in industrial settings for their superior energy efficiency and controllability. Despite these advantages, nonlinear switching in inverters generates significant harmonic distortion, particularly at lower-order frequencies such as the 3rd and 5th, which can compromise power quality, reduce system lifespan, and lead to non-compliance with regulatory standards. This study proposes a hybrid passive filter solution—combining a Double Tuned Filter (DTF) and a High Pass Filter (HPF)—to mitigate harmonic distortion in an industrial HVAC system. Field data collected using a Power Quality Analyzer (PQA) revealed a 3rd-order Individual Harmonic Distortion of Current (IHDi) of 12.9%, far exceeding the 4.0% threshold specified in IEEE 519:2022. The hybrid filter was analytically designed and validated through MATLAB/Simulink simulation. Post-simulation results demonstrated effective mitigation of Total Harmonic Distortion (THD) to 3.45%, with the 3rd-order IHDi mitigated to 3.42%, achieving full compliance with IEEE 519:2022. Furthermore, the hybrid filter preserved voltage waveform quality and suppressed high-order harmonics without incurring additional energy losses or resonance issues. The combination of DTF and HPF offers wide-spectrum harmonic mitigation and enhanced power system stability. This solution is well-suited for high-load, scalable infrastructures aligned with Industry 4.0 requirements. The study concludes that passive hybrid filters are a reliable and cost-effective strategy for harmonic suppression, and future work should explore real-time adaptive control and hybrid active-passive configurations for enhanced dynamic performance
