Abstract

Abstract: This study aims to analyze the feasibility of the grounding system and leakage current in the electrical installation of the Menara Building based on the Indonesian Electrical Installation Standard (PUIL) 2011. The research employed a descriptive quantitative method through direct field measurements using a Kyoritsu 4200 Earth Clamp Tester to measure grounding resistance and a clamp meter to measure leakage current in the distribution panels. The results showed that the grounding resistance value of the transformer grounding system was 11.17 Ω, exceeding the standard limit of ≤ 5 Ω and therefore failing to meet the required standard. Leakage current measurements indicated that several distribution panels were classified as hazardous (>30 mA), particularly those located on the 2nd, 7th, 8th, and 9th floors. In conclusion, the grounding system and several distribution panels in the Menara Building are not yet feasible according to PUIL 2011 standards and require technical improvements to enhance the safety and reliability of the electrical installation system.   Keywords: Electrical Installation; Grounding; Leakage Current; PUIL 2011; Grounding System

Abstract

Abstract:  This study aims to evaluate power quality and analyze its impact on the reliability of electrical distribution systems in a high-rise building. The study employed a quantitative descriptive method through field measurements using a Power Quality Analyzer PEL 103 Chauvin Arnoux installed on the distribution panels of ten floors. The observed parameters included voltage, voltage unbalance, current unbalance, power factor, and total harmonic distortion of voltage (THDv) and current (THDi). The results indicate that the voltage level (229.18–235.02 V), voltage unbalance (0.31–1.17%), power factor (0.86–0.99), and THDv (<5%) comply with IEC 61000, SNI IEC 61000, Permen ESDM No. 04 of 2009, and IEEE 519-2014/2022 standards. However, current unbalance exceeded the permissible limit of 20% on seven floors, and THDi values on several floors exceeded 15%, indicating the presence of nonlinear loads. It can be concluded that the electrical distribution system of the high-rise building exhibits good voltage stability; however, load balancing among phases and harmonic mitigation measures are necessary to maintain the long-term reliability and safety of the electrical installation.   Keywords: Electrical Distribution, Harmonics, High-Rise Building, Power Factor, Power Quality.

Abstract

Provinsi Jawa Tengah menanggung kapasitas PLTU batubara terbesar di Indonesia sebesar 10.222,40 MW, sementara fraksi energi baru terbarukan baru mencapai 21,08 % dari target RUED sebesar 21,32 % pada 2025. Penelitian ini mengevaluasi ketersediaan biomassa pertanian Jawa Tengah untuk co-firing pada delapan PLTU batubara periode 2025 sampai 2030 menggunakan perangkat lunak Low Emissions Analysis Platform (LEAP). Massa biomassa yang tersedia diestimasi menggunakan metode Residue to Product Ratio yang dikoreksi dengan collection factor, diproyeksikan dari data produksi BPS 2020–2024. Hasil proyeksi menunjukkan biomassa tersedia turun dari 16,81 juta ton pada 2025 menjadi 15,79 juta ton pada 2030. Enam skenario co-firing, mengombinasikan dua rasio massa (2 % dan 5 %) dengan tiga skenario nilai kalor biomassa, menghasilkan penurunan input energi panas maksimum sebesar 2,77 %, jauh di bawah batas toleransi operasional 3 % yang lazim diterapkan pada boiler eksisting. Skenario 5 % rata-rata menghindarkan emisi 2,98 juta ton CO2 ekuivalen per tahun dan menaikkan fraksi EBT sektor ketenagalistrikan menjadi 22,51 %, di atas ambang RUED. Penghematan biaya bahan bakar netto berkisar Rp 0,95 sampai Rp 5,86 triliun per tahun tergantung skenario harga batubara. Temuan ini menunjukkan bahwa surplus biomassa pertanian Jawa Tengah memadai untuk mendukung implementasi co-firing, baik secara teknis maupun ekonomi.

Abstract

Kebutuhan energi listrik yang terus meningkat serta keterbatasan energi fosil mendorong pengembangan energi terbarukan, khususnya energi surya melalui teknologi photovoltaic (PV). Namun, peningkatan suhu operasi akibat radiasi matahari menyebabkan penurunan efisiensi listrik panel surya. Penelitian ini bertujuan untuk menganalisis efektivitas Thermoelectric Cooler (TEC) sebagai sistem pendingin aktif pada panel surya serta pengaruhnya terhadap kinerja listrik dan termal sistem. Metode yang digunakan adalah analisis komparatif kuantitatif antara sistem photovoltaic konvensional dan photovoltaic dengan pendingin TEC. Penelitian dilakukan menggunakan panel surya monocrystalline 50 Wp yang diuji pada kondisi lingkungan terbuka. Parameter yang dianalisis meliputi suhu permukaan panel, tegangan, arus, daya keluaran, Net Electrical Efficiency, dan Coefficient of Performance (COP). Hasil penelitian menunjukkan bahwa penggunaan TEC menurunkan suhu panel secara signifikan, dari 45,57 °C menjadi 27,71 °C pada bagian atas dan dari 43,57 °C menjadi 29,86 °C pada bagian bawah panel. Penurunan suhu mencapai 39% dan 31% pada masing-masing bagian. Meskipun TEC memerlukan daya tambahan rata-rata sebesar 2,57 W, sistem menunjukkan nilai Net Electrical Efficiency sebesar 24,97% dan COP sebesar 6,14. Hasil ini menunjukkan bahwa TEC efektif meningkatkan performa termal panel surya, namun optimasi lebih lanjut masih diperlukan untuk meningkatkan efisiensi listrik keseluruhan sistem photovoltaic.

Abstract

This study aims to analyze and compare the electrical and thermal performance of a conventional photovoltaic (PV) panel and an air-cooled Photovoltaic/Thermal (PV/T) system under outdoor operating conditions. The research employed an experimental method involving three system configurations a conventional PV panel without cooling, an air-cooled PV/T system, and an air-cooled PV/T system integrated with a Solar Charge Controller (SCC) and a 12 V battery. A 50 Wp monocrystalline solar panel was used as the test object, while the evaluated parameters included panel temperature, output power, and electrical efficiency. The results indicate that the air-cooled PV/T system with an SCC exhibited the best thermal performance, achieving a maximum panel temperature of 42.90°C, which was 12.35°C (approximately 22.35%) lower than that of the conventional PV panel, which reached 55.25°C. In terms of output power, the conventional PV panel produced the highest maximum output power of 36.50 W, whereas the air-cooled PV/T system with an SCC delivered a maximum net output power of 9.80 W with more stable operating performance. Regarding electrical efficiency, the conventional PV panel achieved a maximum efficiency of 14.90%, while the air-cooled PV/T system with an SCC attained a maximum efficiency of 6.20%, exhibiting a more stable efficiency trend throughout the testing period. Overall, the implementation of an air-cooling system in the PV/T configuration was proven effective in maintaining a stable operating temperature and preserving the electrical performance of the solar panel under tropical environmental conditions.

Abstract

This study aims to reconstruct the principle of good faith as an equitable risk-allocation mechanism in energy contracts involving Electricity Sellers, Electricity Buyers, and Gas Suppliers. The urgency of this research stems from the persistence of trapped risk within Power Purchase Agreements (PPAs) and Gas Supply Agreements (GSAs), where Electricity Sellers bear the consequences of gas supply disruptions beyond their control. This study employs a normative juridical method using statutory, conceptual, case, and comparative approaches analyzed through a qualitative-prescriptive framework. The findings reveal that the existing risk-allocation model fails to reflect contractual fairness because it is inconsistent with the risk follow control principle, while the application of force majeure remains confined to the doctrine of legal impossibility and inadequately addresses commercial impracticability. The novelty of this research lies in the doctrinal reconstruction of the good faith principle into a risk-follow-control-based framework implemented through deemed availability relief, incremental fuel cost pass-through, contractual rebalancing, and loss-sharing mechanisms. This framework strengthens legal certainty, commercial fairness, project bankability, and the sustainability of the energy transition toward Net Zero Emissions (NZE).   Penelitian ini bertujuan merekonstruksi asas iktikad baik sebagai instrumen alokasi risiko yang berkeadilan dalam kontrak energi antara Penjual Jasa Listrik (PJL), Pembeli Listrik (PBL), dan Penyedia Gas (PSG). Urgensi penelitian berangkat dari praktik alokasi risiko dalam Power Purchase Agreement (PPA) dan Gas Supply Agreement (GSA) yang masih menimbulkan trapped risk, yaitu pembebanan risiko gangguan pasokan gas kepada PJL meskipun berada di luar kendalinya. Penelitian ini menggunakan metode yuridis normatif dengan pendekatan perundang-undangan, konseptual, kasus, dan komparatif yang dianalisis secara kualitatif-preskriptif. Hasil penelitian menunjukkan bahwa model alokasi risiko saat ini belum mencerminkan keadilan kontraktual karena tidak selaras dengan prinsip pengendalian risiko (risk follow control), sementara penerapan klausul force majeure masih berorientasi pada legal impossibility dan belum mengakomodasi commercial impracticability. Kebaruan penelitian terletak pada rekonstruksi doktrinal asas iktikad baik menjadi prinsip alokasi risiko berbasis risk follow control melalui mekanisme deemed availability relief, incremental fuel cost pass-through, contractual rebalancing, dan loss sharing. Rekonstruksi ini berkontribusi dalam memperkuat kepastian hukum, keadilan komersial, bankability proyek, dan keberlanjutan transisi energi menuju Net Zero Emissions (NZE).

Abstract

Abstract:The increasing demand for electrical energy in university campuses requires the development of energy systems that are reliable, economically feasible, and environmentally sustainable. This study aims to evaluate the technical performance, economic feasibility, and environmental impact of a hybrid energy system integrating Solar Photovoltaic (PV), Wind Turbine (WT), and Waste-to-Energy (WTE) power generation connected to the utility grid. The research methodology involved collecting renewable energy resource data, electrical load profiles, and techno-economic parameters, which were subsequently analyzed using HOMER Pro software to determine the optimal system configuration. The simulation results indicate that the proposed system is capable of generating 972,876 kWh/year of electricity, with renewable energy contributing 717,784 kWh/year or approximately 73.8% of the total annual energy production. The system achieved a renewable fraction of 75.2%, a Net Present Cost (NPC) of IDR 13.85 billion, and a Cost of energy (COE) of IDR 1,122/kWh. Furthermore, the electricity exported to the grid reached 315,694 kWh/year, exceeding the imported electricity of 255,092 kWh/year, indicating that the system operates as a net exporter. From an environmental perspective, the WTE unit utilizes 88.7 tons of municipal solid waste annually while supporting emission reduction and renewable energy utilization. Overall, the results demonstrate that the proposed hybrid system is technically reliable, economically viable, and environmentally beneficial, making it a promising solution for supporting green campus development and sustainable energy implementation.
