Abstract

Indonesia has the potential for new and renewable energy (EBT), including solar energy as a source of power generation. Energy efficiency can be defined as the ratio between the electrical power generated and the input power received. Low efficiency impacts the electrical power output of solar modules. This underlies the use of Solar Power Plants (PLTS) as a new and renewable electrical energy source to replace fossil fuels that have limited quantities and pollute the environment. Solar cells as PLTS units have the constraint of insufficient output power and are highly dependent on natural conditions. One method of optimizing solar cells is by using sunlight-reflecting glass (reflectors). Sunlight is a renewable energy source that can be utilized as a new power generator. However, in the process, certain additions are required to the solar cell module to optimize the output voltage produced. Efforts to optimize electrical output in solar modules by maximizing the intensity of light falling on the surface of the solar module by using direct sunlight. The results obtained are in the form of a comparison.

Abstract

Transformator tiga fasa merupakan komponen vital dalam sistem distribusi tenaga listrik, namun berpotensi menghasilkan dan menyebarkan harmonisa akibat beban non-linier. Harmonisa ini dapat menurunkan efisiensi, menyebabkan panas berlebih, dan gangguan pada peralatan lain. Penelitian ini bertujuan untuk merancang dan mensimulasikan filter untuk mitigasi harmonisa pada transformator tiga fasa menggunakan perangkat lunak MATLAB. Data bentuk gelombang arus dan tegangan dari ketiga fasa diperoleh melalui pengukuran lapangan. Simulasi dilakukan untuk membandingkan kondisi sistem sebelum dan sesudah pemasangan filter. Hasil menunjukkan bahwa penggunaan filter mampu menurunkan total harmonisa (THD) pada orde ketiga dari 13,17% menjadi 7,02%. Penelitian ini memberikan kontribusi pada upaya peningkatan kualitas daya dan keandalan sistem distribusi.

Abstract

Faktor daya adalah perbandingan antara nilai daya aktif dengan nilai daya semu. Faktor daya menggambarkan sudut perasaan antara nilai daya aktif dengan nilai daya semu. Perbaikan nilai faktor daya umumnya merupakan penambahan sebuah komponen kapasitor bank sebagai pembangkit nilai daya reaktif yang memungkinkan untuk dapat mensuplai kebutuhan nilai daya reaktif kVAR terhadap beban-beban induktif. Kapasitor bank adalah sebuah peralatan listrik yang memiliki sifat kapasitif yang terdiri dari beberapa kapasitor yang disambung secara paralel/seri agar menghasilkan kapasitas kapasitif tertentu. Metode pada penelitian ini menggunakan metode kuantitatif. Penelitian ini bertujuan untuk mengurangi nilai daya reaktif pada sebuah panel MCC 01 di PT Unilever Oleochemical Indonesia dengan cara menaikkan nilai faktor daya pada sistem tersebut yang menggunakan sebuah komponen yaitu kapasitor bank. Hasil pengukuran dan penelitian pada panel MCC 01 tanpa menggunakan kapasitor bank menunjukkan rata-rata nilai faktor daya sebesar 0,81 setelah menggunakan kapasitor bank nilai faktor daya naik menjadi 0,9 dengan begitu nilai daya reaktif pada panel MCC 01 juga berubah dengan nilai daya reaktif awal sebesar 152 kVAR dan setelah pemasangan kapasitor bank menghasilkan daya reaktif akhir sebesar 101 kVAR dengan kapasitas kapasitor sebesar 51 kVAR.Penggunaan kapasitor bank dapat menurunkan nilai daya reaktif dikarenakan kenaikan nilai faktor daya pada sistem yang menggunakan kapasitor bank.

Abstract

Distribution transformers are crucial components in power distribution systems that require real-time monitoring to prevent disruptions and ensure efficient operation. Internet of Things (IoT)-based monitoring systems offer innovative solutions with the ability to detect disruptions early and provide real-time information to operators. This study proposes an optimized early-detection monitoring system for distribution transformers by utilizing IoT devices, including temperature, pressure, and humidity sensors installed on the transformers to monitor their operational conditions. Data collected through the sensors is then processed using a cloud platform for further analysis, with machine learning algorithms used to detect anomalous patterns indicating potential disruptions. Furthermore, the system is designed to send automatic notifications to operators via a mobile application or web dashboard when a disruption is detected, enabling faster response and prevention of further damage. Test results show that the system is capable of detecting disruptions with high accuracy and can improve maintenance efficiency and reduce transformer operational downtime. The implementation of IoT in distribution transformer monitoring also opens up opportunities for optimizing condition-based maintenance management that is more economical and proactive.

Abstract

Load imbalance in three-phase distribution transformers leads to high neutral currents, increased power losses, and decreased system efficiency. This study aims to analyze and simulate load imbalances on distribution transformers located on Feeder LK.10 at PT PLN (Persero) ULP Medan Kota. Data collection was conducted through field measurements of voltage and current, followed by manual calculations and simulations using ETAP 19. The analysis focused on load imbalance percentage, transformer loading, neutral current, and power losses. Results indicate that several transformers exhibit critical imbalance conditions, with some exceeding 25% load imbalance and significant neutral current. The ETAP 19 simulation results show a high level of accuracy compared to actual field measurements, with an average error below 3%. This study confirms that accurate monitoring and proper load redistribution are essential to maintain distribution transformer performance. The findings are expected to support PLN in improving power quality and reliability in distribution systems.

Abstract

This study investigates the impact of imports, exports, Foreign Direct Investment (FDI), and economic growth on the financial performance of governments in ASEAN countries. Utilizing secondary data from the Central Statistics Agency (BPS) and websites www.tradingeconomics.com and www.macrotrends.net, the study analyzes a census sample of all 10 ASEAN countries over the period 2015–2024, resulting in 100 panel data observations. The analysis employs panel data regression with Stata Version 17, supported by Chow, Hausman, and Lagrange Multiplier tests to ensure robustness. Findings reveal that FDI positively and significantly influences government financial performance, whereas economic growth has a significant but negative effect. Imports and exports were found to have no significant impact. These results underscore the importance of prioritizing foreign investment management and fiscal policy adaptation to address the complexities of economic growth while optimizing international trade dynamics in ASEAN countries. This study contributes empirical evidence to the literature by clarifying the distinct effects of key economic variables on government financial performance in ASEAN, offering implications for policy-making and economic governance.
