Abstract

Energy transportation and distribution are crucial components in the national energy system, serving as the main link between energy sources and consumers. The efficiency of both systems is crucial to maintain the stability of energy supply and minimize energy loss during the distribution process. This study aims to explore the importance of energy transportation and distribution in the context of national energy security and the geographical and energy infrastructure challenges in Indonesia. Using a literature study method, this study collects and analyzes literature from various academic sources and relevant reports. The results show that an efficient energy transportation and distribution system plays a major role in reducing the energy gap between regions, expanding energy access to remote areas, and supporting sustainable economic development. In addition, Indonesia's geographical challenges as an archipelagic country, such as the distance between islands and population inequality, widen the energy infrastructure gap between the western and eastern regions. Investment in energy infrastructure development, especially in disadvantaged areas, and the integration of renewable energy are important steps in strengthening national energy security. This study concludes that in order to achieve better and more equitable energy security, inclusive and sustainable energy infrastructure development policies and strategies are needed.

Abstract

Transformator tipe kering menghadapi tantangan utama terkait kenaikan temperatur, rugi-rugi daya akibat temperatur tinggi, serta potensi kegagalan isolasi yang dapat menyebabkan kerusakan, gangguan pasokan daya, hingga penggantian unit. Untuk mengatasi permasalahan ini, berbagai metode diagnostik digunakan, termasuk pengukuran Transformer Turn Ratio (TTR), Winding Resistance, Insulation Resistance, dan Polarity Index. Penelitian ini bertujuan untuk menganalisis kondisi operasional transformator tipe kering berusia 35 tahun dengan kapasitas 2000 kVA, 20/0,4 kV, menggunakan metode diagnostik berbasis pengukuran. Pengujian dilakukan secara off-line dengan konfigurasi rangkaian terbuka menggunakan peralatan berakurasi tinggi, yaitu Omicron CPC 100 dan Megger MIT1025. Hasil pengukuran dibandingkan dengan standar yang ditetapkan oleh International Electrical Commission (IEC), Institute of Electrical and Electronics Engineers (IEEE), serta American National Standards Institute (ANSI). Hasil pengukuran menunjukkan bahwa nilai deviasi TTR berada dalam rentang 0,01% hingga 0,05%, yang masih berada di bawah batas maksimum deviasi sebesar 0,5%, sehingga dapat disimpulkan bahwa transformator masih dalam kondisi baik. Selain itu, hasil Polarity Index berkisar antara 2,41 hingga 4,35, yang memenuhi standar ANSI C57.125-1991, yaitu di atas nilai minimum 2,00, sehingga menunjukkan bahwa kondisi isolasi transformator masih dalam kategori aman. Hasil penelitian ini mengonfirmasi bahwa transformator yang diuji masih dalam kondisi layak operasi berdasarkan parameter diagnostik yang telah diukur.

Abstract

The increase in industrial activity in Indonesia has resulted in a large volume of waste heat that is often discarded without being utilized. One promising solution to convert this waste heat into electrical energy is the use of a Thermoelectric Generator (TEG). This study examines the utilization of the TEG type SP1848-27145 to harness industrial waste heat within a temperature range of 150–250 °C, as well as to evaluate the potential of the generated energy for storage applications. The utilization of industrial waste heat energy is an efficient strategy to support clean energy transition and industrial sustainability. This study aims to analyze the potential of TEG type SP1848-27145 in storing heat energy from industrial waste within a temperature range of 150–250 °C.

Abstract

Indonesia’s rural energy crisis encourages the utilization of existing infrastructure, including technical irrigation networks, as renewable energy sources. This study evaluates the hydroelectric potential of irrigation canals by integrating geospatial analysis and secondary hydrological data to identify feasible micro-hydro power generation sites. The research was conducted along the West Tarum Main Canal managed by BBWS Citarum in West Java, covering a 45 km primary canal segment selected through purposive sampling.The methodology employed Geographic Information System (GIS) spatial analysis using National Digital Elevation Model (DEMNAS) data with an 8.25 m resolution and daily discharge records from Automated Water Level Recorders (AWLR) collected during 2020–2025. Key parameters analyzed included gross head (H_g), dependable discharge (Q₈₀), Manning’s roughness coefficient (n), and head loss.The results identified a total hydroelectric potential of 514.29 kW distributed across five priority nodes, with an average hydraulic head of 3.91 m. A strong positive correlation was found between discharge stability and power output efficiency (r = 0.892; p < 0.001). Nevertheless, sedimentation and inorganic waste remain operational challenges affecting system performance.The study concludes that irrigation infrastructure has economically feasible energy potential due to its proximity to rural load centers, averaging 306 m. These findings support community-based electrification and renewable energy development policies in Indonesia.

Abstract

The use of non linear loads in high rise elevator systems, such as Variable Speed Drives (VSD), provides significant energy efficiency, but on the other hand causes harmonic distortion. This study aims to analyze the harmonic characteristics of a 6 unit elevator system in the PT ASIM Tower using the Total Demand Distortion (TDD) parameter based on the IEEE 519-1992 standard. Measurements were taken at the 400 V voltage common coupling point. The measurement results showed current harmonic distortion (THDi) values of 86% for phase R, 77% for phase S, and 74% for phase T. To assess compliance with IEEE 519-1992, the Total Demand Distortion (TDD) limit was determined based on the ratio between the available short-circuit current (Isc) and the maximum demand load current (IL) at the Point of Common Coupling (PCC). The calculated Isc/IL ratio placed the system in the IEEE 519-1992 category with a maximum allowable TDD limit of 8%. Based on the calculated compensation current requirement, an Active Harmonic Filter (AHF) with a nominal capacity of 32.34 A was identified as a potential mitigation measure. However, verification through post-installation measurements or simulation studies is required to confirm the final TDD level.

Abstract

Perovskite solar cells (PSCs) are a promising next-generation photovoltaic technology due to their high power conversion efficiency (PCE) and facile fabrication. However, structural instability, environmental sensitivity, and operational degradation limit their practical applications. This study investigates the effects of compositional and interfacial engineering on PSC performance and stability. Three perovskite types mixed-cation, interface-modified, and anti-perovskite were fabricated and characterized in terms of crystallinity, morphology, optical absorption, and electrical performance. Mixed-cation perovskites exhibited superior crystallinity, homogeneous morphology, broad optical absorption, the highest PCE (21.0 ± 0.3%), and 86.7% efficiency retention after 500 hours. Interface-modified PSCs enhanced Voc and fill factor, whereas anti-perovskites showed the lowest performance due to poor crystallinity and secondary phase formation. These findings indicate that combining cation/anion compositional engineering with interface modification is an effective strategy for developing high-performance and stable PSCs, offering insights for next-generation photovoltaic device optimization
