Memonitoring Suhu Dan Laju Aliran Gas Pada Destilasi Crude Oil Memanfaatkan Metode Control Proportional Integral Derivative Berbasis Iot Menggunakan Flutter

Abstract

Purification of plastic waste crude oil by distillation process is carried out to produce purer oil products. This research aims to utilise technological advances in producing an Internet of Things (IoT) based monitoring system on crude oil distillation equipment, so that monitoring of the operational conditions of the distillation process can be done remotely in real-time through the flutter platform installed on a smartphone. This monitoring system uses several supporting components such as NodeMCU ESP32 as the main controller and WiFi module, MAX6675 Thermocouple sensor to measure temperature changes in the reactor tube, and servo motor to regulate gas flow in the combustion stove. Crude oil of High Density Polyethylene (HDPE) plastic type is heated in the reactor tube using a heat source from a gas burner. Heating the crude oil causes a change in temperature in the reactor tube which will be detected by the MAX6675 Thermocouple temperature sensor. The input from the temperature sensor will be read by the NodeMCU ESP32 then process the data into outputs displayed on the LCD display and also on the flutter platform. From this research, the process of monitoring temperature changes through a smartphone on the flutter platform has been carried out. With this IoT-based monitoring system, it can help monitor temperature changes more effectively and efficiently during crude oil distillation work.
