Abstract

Perkembangan teknologi dalam bidang perikanan berhasil menghasilkan alat pemberi pakan otomatis yang mampu memberikan kemudahan dalam mengatur waktu dan durasi pemberian pakan. Namun perkembangan ini masih bisa ditingkatkan dengan memperhatikan tingkat pemberian pakan/ feeding rate (FR) di suatu kolam budidaya ikan agar pemberian pakan optimal dan tidak berlebihan. Penentuan FR ini pada prakteknya dipengaruhi oleh beberapa faktor seperti berat atau umur ikan, banyaknya oksigen terlarut dalam air, suhu air dan tingkat kejernihan (turbidity) air. Untuk memperhitungkan pengaruh faktor-faktor tersebut terhadap FR dari alar pemberi pakan otomatis akan digunakan metode fuzzy logic sehingga bisa didapatkan nilai optimal pemberian pakan berdasar pertimbangan faktor-faktor tersebut. Dalam penelitian ini akan dilakukan simulasi penerapan sistem penentuan penyesuaian nilai FR dengan memperharikan faktor-faktor tersebut menggunakan aplikasi MATLAB.

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

Abstract

The insulation condition of high-voltage equipment can be determined by measuring partial discharge (PD), which is an important indicator in insulation degradation. One of the PD detection methods that can be used is to use antennas as sensors in detecting electromagnetic waves generated from PD activities, especially in gas insulated switchgear (GIS) systems. This study focuses on designing and testing dipole antennas in the ultra-high frequency (UHF) frequency range of 300 Mhz-3 GHz to detect PD signals in GIS. Previous studies on dipole antennas with dimensions of 66×15 mm have reported a bandwidth of 336 MHz and a return loss of -22.4 dB at 1.3 GHz. The antenna was fabricated using an FR4-epoxy substrate with a thickness of 1.6 mm, a substrate radius of 102 mm, and a gap distance of 2 mm. Optimization of the antenna length and width significantly improved performance characteristics. Simulation results show that a dipole antenna with dimensions of 35×40 mm antenna produced a wider bandwidth of 989 MHz with a return loss of −28.47 dB at 1.4 GHz. Experimental validation using vector network analyzer (VNA) and PD testing on GIS confirmed that the optimized dipole antenna effectively detected PD activity at a voltage level of 16 kV.

Abstract

Distributed photovoltaic (PV) generation has emerged as a key solution for enhancing the performance of medium-voltage (MV) distribution networks, particularly in isolated systems with limited conventional generation. This study investigates the impact of centralized and distributed PV integration on voltage profile and power losses in the 20 kV East Sumba distribution system. A steady-state load flow analysis using the Newton–Raphson method was performed in DIgSILENT PowerFactory under three PV penetration levels (20%, 50%, and 100% of peak load). The base-case condition shows significant undervoltage at remote buses and total active power losses of 474.47 kW, mainly due to long radial feeders and concentrated loading. The results indicate that centralized PV placement yields the strongest voltage recovery near the interconnection point at 100% penetration, whereas the minimum system power loss is achieved at 50% penetration. By contrast, distributed PV placement provides more uniform voltage support across remote buses, although with lower effectiveness in reducing total system losses. These findings reveal a clear operational trade-off between voltage improvement and loss minimization, implying that the preferred PV placement strategy should be selected according to the specific technical objective of the network. This study provides practical insights for planning and optimizing PV integration in weak and isolated MV distribution systems.

Abstract

The utilization of renewable energy, particularly solar energy, is becoming increasingly crucial in efforts to reduce dependence on fossil fuels and mitigate the impacts of climate change. Higher education institutions play a vital role in adopting and promoting clean energy technologies. This research aims to plan the implementation of a solar power generation system (PLTS) at Siliwangi University Campus II Mugasari using Helioscope software-based simulation. The research methodology includes topographical analysis of the location, evaluation of solar energy potential, and optimization of system design to maximize efficiency and energy output. Helioscope was chosen for its ability to model photovoltaic systems by considering critical variables such as solar radiation, panel configuration, and specific location characteristics. Simulation results indicate that the designed PLTS system has significant potential in generating electrical energy and contributing to the reduction of greenhouse gas emissions. Quantitative analysis includes estimates of energy production capacity, optimal configuration of photovoltaic arrays, and long-term system performance projections. This research provides a comprehensive blueprint for developing renewable energy infrastructure in the campus environment. Additionally, this study contributes to the body of knowledge related to the integration of solar technology in academic contexts and can serve as a replicable model for other higher education institutions in transitioning towards more sustainable and environmentally friendly campuses.

Abstract

Isolator merupakan komponen listrik yang mempunyai sifat dielektrik, berfungsi sebagai pemisah antara konduktor dengan menara saluran udara. Kinerja pada isolator sangat dipengaruhi oleh kondisi lingkungan salah satunya kelembapan udara. Karena kelembapan dapat meningkatkan konduktivitas lapisan kontaminan pada permukaan isolator dan memperbesar risiko terjadinya flashover. Penelitian ini bertujuan menganalisis pengaruh kelembapan udara terhadap tegangan flashover isolator porselen yang terkontaminasi garam NaCl. Metode yang digunakan adalah eksperimen kuantitatif dengan variasi kelembapan relatif 65%, 70%, 75%, 80%, 85%, 90%, dan 95%, sedangkan tingkat kontaminasi NaCl dijaga tetap. Pengujian tegangan flashover dilakukan menggunakan Slow Rate of Rise Test, dan setiap tingkat kelembapan diuji sebanyak sembilan kali. Hasil penelitian menunjukkan bahwa peningkatan kelembapan udara menurunkan tegangan flashover dari 93,66 kV menjadi 57,57 kV dan nilai Equivalent Salt Deposit (ESDD) terukur mengalami kenaikan dari 0,2567 mg/cm² menjadi 0,5857 mg/cm². Kenaikan nilai ESDD ini menunjukkan bahwa kelembapan yang lebih tinggi meningkatkan derajat ionisasi dan efektivtas pelarutan polutan garam di permukaan isolator, yang pada akhirnya meningkatkan konduktivitas permukaan. Temuan ini menunjukkan bahwa kelembapan udara berperan penting dalam menurunkan performa isolasi permukaan, sehingga perlu dipertimbangkan dalam evaluasi keandalan isolator pada lingkungan lembap.
