This article presents the proportional-integral-derivative (PID) parameter tuning on the automatic voltage regulator (AVR) using the chef-based optimization algorithm (CBOA). CBOA is modeling cooking training activities consisting of students and young chefs in an effort to mature cooking skills. This article uses other methods as a comparison in measuring the performance of the proposed method. The methods used are grasshopper optimization algorithm (GOA) and cooperation search algorithm (CSA). The simulation results show that the proposed method, namely CBOA, has a better ability in the peak value of overshoot, which is 0.232% compared to the CSA method and 12.99% compared to the GOA method.

In new renewable energy, the abundant potential of solar energy in Indonesia needs to be utilized effectively, especially in vocational canteens for the purposes of lights and fans. This research aims to design and build an off-grid solar power generation system and Node-Red-based monitoring at the Canteen. The research method used is experimentation through direct observation at the vocational canteen. The tests carried out are the system of SPGS which includes voltage, current, and power and testing monitoring by system sensors and temperature sensors for 5 hours per day in two days. The results obtained are the voltage in the system both panel voltage, AC voltage, and battery voltage are stable and do not exceed the specifications of solar panels. However, the current has increased and decreased although not too drastically and the battery has only decreased by 10%. This is due to the influence of the weather during testing and is not affected by the load power because it does not exceed specifications. In addition, the system sensor has an error of no more than 2% so it can be said that if this system functions optimally and as expected, it can be developed more to save energy.

In this paper, a gradient-based optimizer (GBO) algorithm is presented to optimize the parameters of a proportional integral derivative (PID) controller in DC motor control. The GBO algorithm which mathematically models and mimics is inspired by the gradient-based Newton method. It was developed to address various optimization issues. To determine the performance of the proposed method, a comparison method with the ant colony optimization (ACO) method. It was compared using the integral of time multiplied absolute error (ITAE). They are most popularly used in the literature. From the test results, the proposed method is promising and has better effectiveness. The proposed method, namely GBO-PID, shows the best performance.

The need for electrical energy in modern life is crucial; however, conventional energy sources such as coal, gas, oil, and nuclear have limitations in their availability. Therefore, people are searching for renewable alternatives for electrical energy. This study aims to evaluate the voltage, current, and revolutions per minute generated by a DC generator, as well as the efficiency of a turbine intended for emergency lighting in a tent. The research involves testing the turbine at seven different head heights, ranging from 20cm to 80cm. In this experiment, a water pump with a flow rate of 5 liters per second is used to supply power to three 8-watt DC lamps. The research results indicate that the maximum power that can be generated for tent lighting is approximately 20.83 watts, with an efficiency of 61.09%, achieved at a head turbine height of 50cm.

The unwise use of electrical energy in households can lead to energy wastage and pose risks such as short circuits, which may result in fires. This research developed a Node-Red-based protection system using an ESP8266 microcontroller and a PZEM 004-T sensor to detect voltage, current, and power in real-time. The system automatically disconnects the current when overload conditions are detected, especially on extension cables. Testing was conducted on household devices such as laptop chargers, fans, and soldering irons. Results demonstrate that the system can accurately monitor current and power, maintain electrical stability, and cut off electricity when the load exceeds the safe threshold, thus reducing fire risk. This implementation is expected to enhance household electrical safety and serve as a reference for further development in IoT-based protection systems.
