Abstract

Isolator berperan penting dalam menjaga kestabilan dan keandalan sistem jaringan listrik. Pada kondisi lapangan kontaminasi polutan seperti asap kendaraan pada permukaan isolator dapat mengurangi kekuatan dielektrik dan meningkatkan resiko terjadinya flashover pada isolator, terlebih kondisi basah memperburuk kondisi ini. Karena itu, penelitian ini dilakukan untuk menganalisis pengaruh kontaminasi dan variasi massa polutan asap kendaraan terhadap tegangan flashover isolator. Isolator yang digunakan adalah isolator porselen jenis pasak, dengan polutan berupa jelaga asap kendaraan yang diambil dari knalpot sepeda motor dan variasi massa polutan yang diuji adalah 1, 2, 3, 5, 7, dan 9 g. Proses kontaminasi isolator oleh polutan menggunakan standar IEC 60815-1, dilakukan dengan cara mencampurkan polutan dan 50 ml air aquades lalu mengoleskannya pada permukaan isolator secara merata menggunakan kuas. Pengujian tegangan flashover dilakukan pada kondisi isolator basah dan kering menggunakan tegangan tinggi AC melalui metode Slow Rate of Rise Test. Isolator porselen bersih memiliki tegangan flashover 79,49 kV kondisi kering dan 58,84 kV kondisi basah, setelah dikontaminasi tegangan flashover menurun seiring dengan penambahan massa ploutan hingga mencapai 48,69 kV kondisi kering dan 28,54 kV kondisi basah pada massa polutan 9 g. Penelitian ini juga mengukur NSDD (Non-Soluble Deposit Density) untuk mengetahui tingkat deposit polutan pada isolator. Nilai NSDD meningkat seiring dengan penambahan massa polutan, mulai dari 0,6 mg/cm² untuk 1 g polutan hingga 5,53 mg/cm² untuk 9 g, yang berkontribusi pada penurunan tegangan flashover dan performa isolator porselen.

Abstract

This community service program was conducted in 2025 with the Taruna Tani Sukamandiri Farmers’ Group in Ciamis Regency to address water scarcity and high fuel dependency in rainfed farming. An automatic solar-powered water pump system was introduced to strengthen energy independence, reduce irrigation costs, and increase the productivity of chili and cucumber crops. The program was implemented through five stages: coordination, technology installation, training, mentoring and evaluation, and ensuring sustainability. Results showed a significant reduction in diesel pump usage, cutting operational costs by IDR 1–1.5 million per season. Irrigation efficiency improved crop yields during the first two harvests, although the third harvest declined due to excessive rainfall. Farmers actively participated in installation, training, and maintenance, while students gained valuable hands-on learning. Academic outputs include a submitted journal article and a draft technical manual being processed for intellectual property rights, making this program a replicable model of sustainable agriculture.

Abstract

The increasing demand for electrical energy, along with economic growth and regional development, requires power systems to have a high level of reliability. One of the common problems in power systems is the overload condition on power transformers, particularly during load transfers caused by faults or network maneuvers. If left unaddressed, overload conditions can cause excessive temperature rise, accelerate insulation degradation, and potentially lead to widespread blackouts. Therefore, a protection scheme in the form of overload shedding is necessary to maintain system continuity and reliability. This research aims to analyze overload shedding scenarios during load transfers at the 150 kV Cilawu Substation. The analysis was conducted to determine the condition of the power transformer under normal conditions, during fault conditions, and throughout the manual overload shedding process based on a load selection scheme. The research methods used include literature study, substation system data collection, network modeling, as well as load and load shedding simulations using ETAP 19.0.1 software and script-based MATLAB. The analysis focuses on static loading conditions without discussing transient effects and dynamic system stability. The results show that the implementation of the overload shedding scheme is capable of reducing the power transformer loading to within safe limits, thereby preventing transformer tripping and wider blackouts. Furthermore, proper load selection during the load shedding process plays a crucial role in maintaining the electricity supply to priority loads. Thus, the overload shedding scheme can be utilized as an operational strategy to improve power system reliability at the 150 kV Cilawu Substation.

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 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

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.
