Abstract

Penelitian ini membahas perhitungan intensitas medan listrik pada Saluran Udara Tegangan Tinggi (SUTT) 150 kV di jalur Lubuk Alung – Padang Industrial Park – Pauh Limo yang mengalami relokasi akibat pembangunan jalan tol. Kajian difokuskan pada perhitungan parameter teknis seperti andongan konduktor, jarak antar fasa, tinggi konduktor, dan jari-jari konduktor berdasarkan data dari PT. Maxima Arta. Metode analitik elektrostatis digunakan untuk menghitung intensitas medan listrik pada tiga titik uji utama: permukaan jalan tol, kendaraan yang melintas, dan safety net. Hasil perhitungan menunjukkan bahwa intensitas medan listrik tertinggi sebesar 6,040 kV/m terjadi pada safety net yang telah di-grounding, sehingga tidak menimbulkan risiko bagi manusia maupun lingkungan di bawahnya. Nilai medan listrik pada titik uji jalan dan kendaraan berada dalam batas aman sesuai SNI 04-6918-2002 dan rekomendasi WHO. Dengan demikian, relokasi SUTT 150 kV pada jalur ini dinyatakan aman dari aspek paparan medan listrik dan dapat dijadikan referensi teknis dalam perencanaan ulang jaringan transmisi di area publik

Abstract

The crucial challenge in Condition Monitoring (CM) and Predictive Maintenance of high-voltage (HV) equipment is achieving reliable detection and precise localization of the Partial Discharge (PD) source. PD is a vital indicator of insulation degradation. This challenge is compounded by the complex and non-homogeneous operational environment, where internal structures like transformer windings and cores significantly distort and attenuate signals, while simultaneously creating the phenomenon of acoustic multipath. This critical analysis examines the convergence of advancements in sensor technology, calibration techniques, and sophisticated algorithms in the effort to overcome these PD localization challenges. The review highlights significant progress across various sensor types, including Acoustic Emission (AE) sensors optimized with the KLM Model to enhance sensitivity, UHF sensors that offer superior noise immunity, and innovative pressure-balanced fiber-optic acoustic sensors specifically designed for detecting dual PDs. To achieve higher localization accuracy, signal processing techniques have evolved beyond the basic Time Difference of Arrival (TDOA) method. Currently, robust algorithms are applied, such as Generalized Cross-Correlation with Phase Transformation (GCC-PHAT), which effectively suppresses noise and reflections, and Particle-Swarm-Optimization Route-Searching (PSORS) to intelligently model the acoustic signal propagation paths around internal obstructing structures. Alternative approaches also include online localization based on electrical Transfer Function analysis. The integration of highly sensitive sensor technology with intelligent pathfinding algorithms is key to realizing accurate multi-method diagnosis, thereby supporting more reliable and efficient operation of HV equipment

Abstract

Indonesia is located within the Pacific Ring of Fire, one of the most seismically active regions in the world due to the interaction of multiple major tectonic plates. Understanding the spatial distribution of earthquakes and accurately estimating their magnitudes is essential for effective disaster risk assessment and mitigation planning. This study aims to analyze earthquake distribution patterns and develop a machine learning-based approach to predict earthquake magnitude using seismic data from the Meteorology, Climatology, and Geophysics Agency (BMKG). The study employs two machine learning methods: K-Means Clustering to identify spatial groupings of earthquake events and Random Forest Regression to predict magnitude based on spatial and temporal features. The dataset consists of 67 earthquake events recorded in February 2026, including attributes such as latitude, longitude, depth, magnitude, and occurrence time. Clustering results indicate that the optimal number of clusters is k = 4, with a Silhouette Score of 0.3444, suggesting a moderate clustering structure. This implies that spatial patterns are present, although cluster separation is not yet well-defined. The Random Forest model achieved an R² of 0.7382 on training data and 0.0975 on testing data, indicating overfitting likely due to the limited dataset size. Feature importance analysis reveals that longitude contributes the most (43.7%), followed by depth (29.6%), latitude (20.6%), and time (6.0%). These findings highlight the dominant role of spatial factors in Indonesia’s seismic activity. However, the limited dataset restricts model generalization; therefore, future studies should use larger datasets and incorporate additional geophysical parameters to improve predictive performance.

Abstract

This study aims to design and evaluate an on-grid Solar Power Generation System (PLTS) for the Water Treatment Plant (IPA) Taban III in Lubuk Minturun, Padang, addressing the lack of research on on-grid PLTS in government-operated water treatment facilities. Using an engineering design approach, the study covers energy load analysis, Helioscope simulation, and economic feasibility assessment. The site has an average daily solar irradiance of 4.91 kWh/m²/day. The total facility load is 34.32 kW (40,376.47 VA). The PLTS is designed to supply 20% of this, prioritizing a 2.3 kW active load with daily energy demand of 13.8 kWh. The proposed system consists of 27 monocrystalline solar panels (550 Wp) and a 20 kW three-phase grid-tied inverter. Simulation results show an annual energy output of 19,287.9 kWh and a Performance Ratio of 78.06%. The PLTS supplies approximately 59% of daily load demand, with the remaining 41% from the PLN grid via net metering. Deviation between manual calculations and simulation is below 0.5%. Total investment is IDR 239,250,476 with annual savings of IDR 23,419,400, yielding a payback period of approximately 10 years and 3 months. The system is feasible and supports national renewable energy targets, and is recommended for similar public utility facilities.

Abstract

The government's initiative to enhance energy resilience and independence includes the augmented use of green energy. PLTA Singkarak is a renewable energy facility that harnesses water from Lake Singkarak to operate its turbines, featuring an average tailrace discharge of 30 m³/s. The Singkarak Hydroelectric Power Plant receives its energy from PLN's Singkarak Substation, utilizing a 5 MVA transformer for distribution to meet its own consumption needs. Consequently, each month, the Singkarak Hydroelectric Power Plant must reduce its total kWh output by its own use, averaging 4,127.8 kW each day. A small-scale Micro Hydro power plant will be developed to utilize the potential water source at the outflow of the Singakrak Hydroelectric Power Plant, serving as the primary supply for the facility, and so decreasing the company's performance target for its own consumption. A sufficiently big outflow tailrace discharge is likely to be repurposed for a micro-hydropower plant. The initial elevation of the Singkarak Hydroelectric Power Plant tailrace exit is 71 meters above sea level, whereas the end elevation is 67 meters above sea level, as measured by hand. A micro-hydropower plant (PLTMH) can be engineered with a net head of 3.8 m and a flow rate of 10.618 m³/s, yielding a maximum power output of 327.8 kW. The turbine employed is a Kaplan turbine, while the generator utilized is a 3-phase synchronous generator, with both components functioning at 1000 rpm . This PLTMH design can supplant the self-consumption of the Singkarak hydropower plant (PLTA), hence enhancing the system's energy efficiency.
