Abstract

Lithium-ion (Li-ion) batteries are one of the battery technologies widely used in electric motorcycles (EVs) because they have high efficiency and good durability. This battery functions as the main energy source for electric vehicles and is an important component in supporting vehicle performance. This study aims to analyze the characteristics of Lithium-ion batteries in electric motorcycles by considering factors such as operating temperature, voltage, and the influence of speed and terrain. Tests were carried out on flat and uphill tracks with speed variations of 10 km/h, 30 km/h, and 50 km/h. The results showed that Lithium-ion batteries tend to experience a faster increase in temperature when used at high speeds, but the battery voltage remains stable during the Discharge and Charging process without any significant spikes. These findings provide insight into the performance of Lithium-ion batteries in electric vehicles, as well as the importance of temperature management to maintain optimal battery performance.

Abstract

A hybrid solar-wind power plant is a combination of two renewable energy sources, namely solar and wind energy, used to generate electricity. This study aims to analyze the performance and efficiency of a hybrid solar-wind power system as a practical learning tool. The research methodology involves collecting performance data from solar panels and wind turbines, as well as analyzing the integration of these two energy sources. The results show that the hybrid system can enhance the stability and continuity of electricity supply compared to using a single energy source. The implementation of a hybrid solar-wind power plant as a learning tool provides students with a deeper understanding of the application of renewable energy technologies and encourages innovation in the field of sustainable energy.

Abstract

Power system stability is a critical factor in maintaining the continuity and quality of energy supply, especially in transmission systems that face load fluctuations and integration of renewable energy sources. The main problems in this study are voltage instability and reactive power oscillations that often occur due to disturbances such as sudden load changes or short circuits, as well as the limited capacity of conventional controllers in reducing these impacts. This study aims to explore the role of Static VAR Compensator (SVC) as part of Flexible AC Transmission Systems (FACTS) technology in improving transmission system stability through a qualitative approach. The research method is carried out with descriptive analysis based on literature studies, mathematical modeling of the power system, and numerical simulations to understand the dynamics of the system response to disturbances. The focus is given to qualitative evaluation of the interaction between SVC, system parameters (voltage, reactive power, and phase angle), and the impact of controller placement on network reliability. Simulation case studies cover small to large disturbance scenarios to assess the effectiveness of SVC in restoring stability. The results show that SVC integration makes a significant contribution to improving the dynamic stability of the transmission system. Qualitative analysis finds that SVC is able to reduce voltage oscillations and accelerate post-disturbance system recovery through adaptive reactive power regulation. However, the limited capacity of SVC in handling extreme disturbances indicates the need for combination with other FACTS controllers (such as STATCOM or UPFC) for more complex systems. This study also reveals the importance of proper SVC placement strategy to optimize its effectiveness.

Abstract

Solar Power Plant is a power generation system that uses solar energy to generate electricity. PLTS components consist of solar panels, solar charger controller, battery and inverter. Solar panels are used to convert solar energy into DC electrical energy. The solar charger controller functions to regulate the voltage value distributed to the battery. The battery is used to store electrical power and the inverter is used to convert DC current to AC. In its use, the components installed on the PLTS need to know the efficiency percentage so that the amount of electrical energy utilization that can be generated can be known. This study aims to analyze the efficiency of electrical energy generation produced by solar panels with a capacity of 250 WP and a 2000 W inverter. Tests were carried out 5 times within a 5-hour time span (10:00 WIB – 14:00 WIB) using a 350 W Water Pump load. The test results showed that the solar panels were able to produce an average power of 76.39 W, with the largest power reaching 86.55 W. The calculated solar panel efficiency was 15.13%. The battery efficiency, based on the highest power measured, reached 0.80%. The inverter's power output varied, averaging 919.6 watts, with the highest output reaching 935 watts.

Abstract

The stability of a three-phase power supply is crucial for ensuring the reliable operation of photography studio equipment, which is generally sensitive to electrical disturbances. One common disturbance is phase failure, which can cause equipment damage, reduced work quality, and safety risks. This study aims to analyze and implement a microcontroller-based phase failure detector system capable of detecting abnormal conditions in a photography studio's electrical system quickly and accurately. The system is designed using an ATmega328P microcontroller integrated with voltage sensors on each phase. When one of the phases fails, the system will provide a warning via a buzzer and LED indicator, and can optionally disconnect the load to prevent further damage. Test results show that this detector is capable of detecting the loss of a phase in less than 1 second with an accuracy level of XX% (adjusted based on the results). Thus, this system can improve protection for studio equipment and support more reliable operations.

Abstract

Energy consumption in office buildings represents a significant portion of operational costs and environmental impact. Efficient energy management has therefore become a critical priority. This study analyzes the potential of implementing remote monitoring and control systems to improve energy efficiency in office buildings. The system integrates Internet of Things (IoT) technologies and microcontroller-based controllers to monitor and regulate electrical loads such as lighting, air conditioning, and other office equipment. Data collection and analysis were conducted through sensor integration, cloud-based dashboards, and control algorithms. The results show that real-time energy monitoring and automated control can reduce unnecessary energy usage by up to 25%, improve responsiveness to occupancy patterns, and enable predictive maintenance. The system also supports remote access via web or mobile interfaces, allowing facility managers to make informed decisions. The findings suggest that remote monitoring and control systems offer significant potential to enhance energy efficiency, reduce operational costs, and contribute to sustainable building management practices.
