Abstract

Abstract. This study aimed to identify production losses that occur in the Clearator Unit in one of the state-owned drinking water treatment companies so that the implementation of improvements can increase the effectiveness of the process. The Clearator Unit, as the object of the research, is a flocculation building used to accelerate the sedimentation in processing raw water into usable water. The methodology used to achieve the research objectives is the Six Big Losses and Overall Equipment Effectiveness (OEE) approach for production loss analysis. In addition, quality tools such as the Ishikawa Diagram and Linear Regression were used to identify the causes of losses and formulate improvement solutions. From the results of this study (based on August 2022), it was found that the losses were “reduced speed” and “defect process”, with OEE values of 37%. This value indicated that the effectiveness of the Clearator Unit is below the standard limit of world-class company (OEE value should be more than 85%). The proposed improvement was to create a standardized dosing usage of Aluminium Sulfate (alum) to improve the water output quality. The alum standard dose based on the equation of the regression test results was: “decreased water turbidity (NTU)” = 2,497 + 0,00099 “alum usage (kg)”. This solution implementation can affect the production of higher-quality clean water (SDG6) and more responsible production governance (SDG12).
