KINERJA SISTEM MONITORING SCADA PADA PLANT SISTEM PENDINGIN DAN AHU

Abstract

This research discusses the design and implementation of a Supervisory Control and Data Acquisition (SCADA) system for centralized monitoring of cooling systems and Air Handling Units (AHU) that previously operated separately. This integration aims to improve monitoring efficiency and facilitate real-time supervision. This research covers the design of the SCADA display, communication configuration using the Modbus TCP/IP protocol, and the implementation of alarm and alarm data logger features. Testing was conducted by comparing temperature parameter data between SCADA and the plant HMI to measure the level of accuracy. The test results showed 100% accuracy for all parameters tested, indicating that the system has high reliability in data acquisition. Additionally, the SCADA system can respond quickly to various disturbances and automatically log all alarms into a database. With these features, the system offers benefits in early disturbance detection, integrated monitoring data, and historical documentation useful for evaluation. Overall, SCADA has proven effective in enhancing the performance and efficiency of the HVAC system monitoring system as a whole.
