Abstract

Application of Temperature Monitoring and Blowing Machine Control System Technology Based on a Programmable Logic Controller in the Plastik Bottle Production Process at CV. Nugroho Plastik is a tool used to monitor the liquid temperature of plastik pellets to drive the plastik pellet machine in the blow molding process at CV Nugroho Plastik, which can operate both manually and automatically. The aim of creating this system is to reduce damage to the plastik ore pushing machine due to the plastik ore liquid not being hot enough or vice versa, which can result in broken axles in the plastik ore pushing machine. The control used in the temperature monitoring and blowing machine control system is PLC CP1L M30DT expansion CP1W-TS002. as a plastik ore sensor, 2 Type K thermocouples are used, while to monitor the output and provide input to the controller used, namely HMI NB7W TW00B. The plastik ore temperature value in this tool is set in the range of 130°C to 190°C. The results of applying this technology show that the type K thermocouple sensor has an accuracy of 99.7% in reading the temperature of the plastik ore heating machine, and in general, the system implemented has succeeded in increasing the effectiveness of the production process. Apart from that, this system has shown good performance in controlling the blowing machine based on the temperature of the pusher machine.
