The Integration of Six Sigma and FMEA Methods in Determining Crude Palm Oil (CPO) Quality Improvement Factors at the Cot Girek Palm Oil Mill Unit of Pt. Perkebunan Nusantara-1

Abstract

AbstractThe Cot Girek Palm Oil Mill (POM) Unit of PT. Perkebunan Nusantara-1 adheres to high-quality standards in order to meet the company’s objectives. According to the study’s findings, there is still many data on the quality levels of Crude Palm Oil (CPO) that exceed the upper limit of the standards set, such as in 2019, the average free fatty acid (FFA) content of 3.59%, moisture content of 0.26%, average free fatty acid (FFA) content of 3.65%, and moisture content of 0.27% in 2020. Meanwhile, CPO impurity levels remain within the company’s control limits. The purpose of this study is to prioritize actions to increase CPO quality. According to the findings of this study, the raw material of fresh fruit bunches (FFB) containing free fatty acids and high moisture content with an RPN value of 504 is one of the elements that reduce CPO quality levels. Furthermore, the equipment at the continuous clarifier station, pure oil tank, oil purifier, and vacuum dryer do not operate efficiently, preventing them from effectively separating water, impurity, and CPO with an RPN value of 448.
