Electrical power distribution has risks that cannot be avoided, namely short circuit disturbances, both symmetrical and asymmetrical, temporary or permanent. Electricity providers' efforts to avoid or localize disturbances use protection systems, one of which is the Over Current Relay (OCR). The use of OCR in electric power transmission or distribution networks requires careful current and time settings according to the characteristics of the fault and the location of the fault. As an effort to facilitate operators and academics in the process of understanding and providing learning media or training to be able to simulate the current and time settings of OCR in securing the electric power transmission/distribution network, an OCR setting simulator of the electric power transmission or distribution network system is needed. built electronically using a microcontroller. The simulator built represents a three-phase electrical network with treatment of single-phase, inter-phase and three-phase faults. In each type of short circuit treatment, the fault current that occurs in section I (upstream) is greater than the fault current that occurs downstream, namely section II and section III. The working time of the relay in each section is faster at greater fault current values which are influenced by the variable TMS (Time Multiple Setting) and setting current (IS) values

The tool is designed to ensure that solar panels are always positioned perpendicular to the sun using an Arduino Uno as an automatic controller, along with other components such as light sensors (LDR) and DC motors. This microcontroller operates by processing data from the LDR sensors using programming on the Arduino Uno. When the LDR sensor is not aligned with the sun, its resistance value will differ. If this difference occurs, the microcontroller will move the motor to adjust the solar panel until the resistance returns to an equal value. The data logger monitoring aims to track the power capacity of the solar panels. Arduino is capable of generating optimal voltage when the solar panel is perpendicular to the direction of the sun. Based on tests conducted by comparing static solar panels with solar panels equipped with dual-axis trackers, it was found that solar panels with dual-axis trackers have a more optimal solar energy absorption capability. This is evident from the measurement of the electrical voltage generated, where the voltage on solar panels with dual-axis trackers is higher compared to static solar panels or those using single-axis trackers. The data obtained shows an increase in voltage starting at 09:00, with the maximum voltage recorded at 13:00, before eventually declining. The Data Logger can be monitored using the Blynk application, allowing it to be tracked through the Internet of Things (IoT).

Water turbidity is a critical factor affecting fish growth and health in aquaculture, thus requiring an efficient and automated water quality monitoring system. This study developed an Internet of Things -based system powered by solar energy to monitor and control water quality in real-time. The system uses an ESP32 microcontroller integrated with turbidity, pH, and temperature sensors, as well as water level control, automatic feeder, and an INA219 power monitoring module. Sensor data is transmitted via Wi-Fi to a Firebase-based web dashboard. When turbidity exceeds 25 NTU or pH falls outside the 6.5–8.5 range, the system automatically activates a solenoid valve to discharge dirty water, runs a pump to refill clean water, and injects a pH balancing solution, while sending notifications to the user. Test results show an average response time of 2–3 seconds, with sensor accuracy of ±0.2 for pH, ±0.5°C for temperature, and ±5 NTU for turbidity. The system demonstrates high energy efficiency, consuming approximately 12.6 Watts, with solar panel voltage maintained between 12.9–13.5 Volts, and battery capacity stable at 87–95%. Data transmission is stable, with synchronization to the server occurring in less than 1 second. With reliable performance, quick responsiveness, and energy efficiency, this system proves to be effective in supporting sustainable fish farming, especially in areas with limited access to conventional electricity.

This study aims to analyze the impact of radiator leakage in the main transformer on the power generation performance at the Ampelgading Hydroelectric Power Plant, Malang. Radiator leakage reduces the volume of insulating oil, leading to increased operating temperatures and degradation of insulation quality. A quantitative descriptive method with a case study approach was employed by analyzing temperature data, Breakdown Voltage (BDV), Dissolved Gas Analysis (DGA), and energy production data before and after the disturbance. The results indicate that radiator leakage caused a significant increase in winding and oil temperatures, along with a decline in insulation oil quality marked by elevated dissolved gas levels. Operationally, the disturbance resulted in a power output reduction of 18.27%. Corrective actions, including cold welding, load reduction, and oil purification, were effective in restoring transformer performance, as evidenced by an average BDV value of 68.1 kV categorized as very good, and improved energy production after maintenance. This study concludes that the reliability of the transformer cooling system, particularly the radiator, plays a crucial role in maintaining operational stability and efficiency in hydroelectric power generation.
