Abstract

This research focuses on studying the improvement of efficiency in data collection and process control in packaging production using the Internet of Things (IoT) combined with Total Productive Maintenance (TPM). The initial step involves addressing issues identified in the packaging production department that affect product quality, with the primary problem being packaging leakage. Techniques such as the 7 QC Tools and Why Why Analysis were employed to identify and analyze the root causes. The analysis revealed that the cooling water system using a chiller could not maintain the temperature according to standards due to lack of maintenance. Thus, the cooling water system was redesigned, and IoT devices were installed, including Arduino Uno and Raspberry Pi 4, to collect data and create a dashboard for controlling the cooling water temperature. Data was stored using Google Sheets. Post-installation, the system could log real-time chiller operations. The collected data was then analyzed to plan TPM implementation using three pillars: Equipment and Improvement, Autonomous Maintenance, and Planned Maintenance. The research results demonstrate significant success in reducing the number of packaging leakage cases from 40 incidents before improvement to just 2 incidents afterward, marking a 95% reduction. The enhancement of the cooling water system effectively addressed the issues, reducing production risks and increasing product efficiency. The integration of IoT with TPM in the chiller cooling water production process serves as a model for further improvements in other production process areas, enhancing overall efficiency.
