Abstract

PT Petrokimia Gresik requires a high-quality supply of demineralized water to support the performance of turbines and boilers in the production process. The quality of demineralized water plays a crucial role in energy efficiency and operational continuity. This study aims to analyze the types, causes, and control of defects in demineralized water by integrating the Six Sigma method, New Seven Tools, and Failure Mode and Effects Analysis (FMEA). The results indicate that the highest defect rates occur in the parameters of Total Hardness (TH), SiO₂, and conductivity. The main causes include suboptimal resin regeneration processes, instability in operational parameters, and weak quality control and instrument calibration. A Defect per million opportunities (DPMO) value of 20,673.48 and a sigma level of 3.5 indicates that the process has not yet reached optimal quality, although it remains within statistical control limits. Proposed improvements include optimizing Standard Operating Procedures (SOPs) for resin regeneration, retraining operators, scheduling regular calibrations and equipment inspections, developing an online quality monitoring system, and implementing routine preventive maintenance on key units, such as cation, anion, and filter systems. This approach is expected to sustainably enhance the quality of demineralized water.
