Abstract

ABSTRACT This research investigates a battery charging system using renewable energy with the help of a buck converter, which functions to step down the voltage from the renewable energy source to a level suitable for the battery. The test results show that the battery charging voltage remains stable between 12.5 to 13.8 volts during 3 days of charging. The buck converter plays a crucial role in maintaining charging efficiency by dynamically adjusting the voltage and current according to the battery's needs. The system also maintains good stability, with automatic monitoring that adjusts the charging process based on fluctuations in solar intensity. The sustainability of the system is achieved through the use of solar energy, reducing reliance on fossil fuels. The automation of the charging process allows the system to operate independently without human intervention, enhancing efficiency and convenience. Thus, this system is not only efficient and stable but also supports the more sustainable and environmentally friendly use of renewable energy. Keywords: Renewable energy, battery charging system, buck converter, voltage stability, solar energy ABSTRAK Penelitian ini mengkaji sistem pengisian baterai menggunakan energi terbarukan dengan bantuan buck converter, yang berfungsi untuk menurunkan tegangan dari sumber energi terbarukan ke level yang sesuai untuk baterai. Hasil pengujian menunjukkan bahwa tegangan pengisian baterai tetap stabil antara 12,5 hingga 13,8 volt selama 3 hari pengisian. Buck converter berperan penting dalam menjaga efisiensi pengisian dengan menyesuaikan tegangan dan arus secara dinamis sesuai kebutuhan baterai. Sistem ini juga mempertahankan stabilitas yang baik, dengan pemantauan otomatis yang menyesuaikan pengisian berdasarkan fluktuasi intensitas sinar matahari. Keberlanjutan sistem tercapai melalui pemanfaatan energi surya yang ramah lingkungan, mengurangi ketergantungan pada energi fosil. Otomatisasi pengisian memungkinkan sistem berjalan secara mandiri tanpa intervensi manusia, meningkatkan efisiensi dan kenyamanan. Dengan demikian, sistem ini tidak hanya efisien dan stabil, tetapi juga mendukung penggunaan energi terbarukan yang lebih berkelanjutan dan ramah lingkungan.

Abstract

This study analyzes the power flow in the 150 kV Kedinding–Bangkalan Transmission Circuit using two simulation platforms, ETAP and MATLAB Simulink, to evaluate the performance of the transmission system and ensure the sustainability of the electrical power supply. Power flow analysis is essential in electrical systems to determine steady-state conditions, including voltage, current, active power, and reactive power. The Kedinding–Bangkalan circuit plays a crucial role in the stability of the electricity supply to Madura Island, which relies on energy from Java Island. The objective of this study is to compare the simulation results between ETAP, which uses the Newton-Raphson method for high accuracy, and MATLAB Simulink, which is more flexible in dynamic modeling. The simulation results show that the voltage profiles from both platforms are highly consistent, with minimal differences in active and reactive power (less than 2%). ETAP's simulation slightly underestimates the power loss (around 1.5%) compared to Simulink, but both show good stability under full load and fault conditions, with respective power losses recorded at 3.2% and 3.5%. These results indicate that both platforms can be used together to obtain a more comprehensive view of the transmission system's performance. Their integration allows for the exploration of more complex scenarios, such as load variations and faults, while enhancing simulation accuracy. This research is expected to contribute to the development of more effective and adaptive transmission system analysis methods, strengthening the reliability and efficiency of power systems, and supporting decision-making in transmission network planning and management

Abstract

Graphical user interface is a subset of HCI in the form of interaction between humans and machines through a graphical user interface. GUI is used by various fields of engineering, electronics, economics and even medicine. The development of graphic hardware has triggered various fields to visualize various models in order to increase knowledge. This systematic review aims to provide clear information about the influence of the graphical user interface on monitoring voltage, current, and frequency. Testing the ESP32 microcontroller that has been carried out shows that the output voltage at condition 1 averages a value of 3.5 V and when at condition 0, the output voltage is 0.38 V. Designing a 3-phase electricity monitoring system equipped with a power controller using a desktop application in real time, this is made for efficient use of electricity and control in electrical safety systems in an industry

Abstract

This research explores the design and development of the Smart Solar Cell Lamp an environmentally friendly garden lighting system that runs on renewable energy. The lamp is powered through a hybrid system that combines solar panels as the main energy source with a PLN (state electricity) adapter as a backup, allowing it to operate reliably even when sunlight is limited. To make the system more efficient, an LDR (Light Dependent Resistor) sensor is used to automatically adjust the LED brightness according to the surrounding light conditions. The research applies a prototype approach, starting from identifying the core problem to designing, assembling, and testing the device. Test results show the solar panel consistently generates voltage between 15.69 V and 16.49 V, with the battery storing up to 13.30 V. During nighttime operation, the system maintains a steady supply of current and voltage to power the LEDs. The LDR sensor responds well to changes in ambient light, allowing the lamp to switch on and off automatically without user input. While the system performed as expected under lab conditions, further improvements such as better weather protection, enhanced durability, and remote monitoring are recommended to support long-term use and real-world deployment
