Abstract - The need for an effective and efficient control system is now increasingly needed, for example in the waste sorting industry that uses a gasoline engine conveyor belt as a means of mobilizing waste to be sorted, but different waste loads result in unstable conveyor belt movements. This study aims to control the rotational speed of the gasoline engine by applying sensors and control actuators that are implemented with the PID control system algorithm, as well as finding the right KP, Ki, Kd parameter values so that the speed can reach the set point with the best time and stability. The study was conducted on a Stihl PC-75 gasoline engine using a hall effect sensor as a speed sensor, a potentiometer sensor used to determine the gas position, and a speed control actuator, namely a DC motor designed to pull the throttle throttle cable, to process data processing carried out on a microcontroller. Arduino Mega 2560. The results obtained from this study are the hall effect sensor is able to read speeds up to 18000 rpm using a moving average filter worth 25 sampling, and the gas control actuator is able to work on this system, the best PID parameter value to reach the set point of 8000 rpm is at the value of Kp = 0.51, Ki = 0.3, Kd = 5, it takes 15.5 seconds to reach a stable state and with a stability error of 3.88%.

Increasing the effectiveness and efficiency of agriculture can be done by applying sensor technology, automation, monitoring, and remote control through the Wireless Sensor Network (WSN). One of the technologies used is Bluetooth Low Energy (BLE). The presence of the ESP32's System on Chip (SoC) makes it possible to implement a battery-powered WSN device that is suitable for agricultural purposes when the electrical infrastructure is limited. In this research, a battery-powered BLE sensor node prototype has been created. The node can transmit temperature, humidity, and battery level information. The data sent has been designed based on the Bluetooth Generic Attribute Profile (GATT) standards and specifications. nRF Connect’s application shows that the data sent by the designed node complies with the GATT attributes standard. Testing of temperature and humidity sensor readings has also been carried out with 1% and 2.2% errors respectively. Tests were also carried out on battery-level readings and a 4.2% error was obtained. Through distance testing between nodes, the node can transmit data properly up to 10 meters.
