In Indonesia, banana production is the highest compared to other fruits. One of the variations is the Cavendish Banana, which has high economic value and has the potential to support Indonesia's economic recovery. Due to the high demand for Cavendish Banana fruit, farmers use ethylene gas to accelerate fruit ripening. The ripening process is done by manually directing the ethylene gas taken from the container to the ripening room through a pipe system. The purpose of this research is to create a prototype of an automatic system for ethylene gas usage and temperature control, where compressor pressure is an alternative to ethylene gas pressure. This system operates automatically according to the schedule that has been set on the RTC Module. There is a Pressure Transmitter Sensor in charge of measuring pressure with an error rate of 3.5%, a Selenoid Valve that plays a role in flowing air pressure into a box equipped with a DC fan as a spreader, and a DHT22 Sensor used for temperature monitoring with an error rate of 2.8%. Information regarding time, temperature, and pressure values are displayed on a 20x4 LCD screen. System testing involves time scheduling where the device is turned on one minute after the system is activated. Subsequently, the device was switched on again after different times of 2 and 5 minutes. The pressure value was set at 30Psi. Based on the results of the system automation testing, the device was successful with a success rate of 80%, so this automation system is ready to be implemented directly on the Cavendish Banana fruit ripening device.
