Quality is one of the issues that requires special attention in the operation of a company since it can affect the relationship between producers and consumers as well as reduce the company’s losses. PT. Z is a company that mainly produces Crude Palm Oil (CPO) and Palm Kernel Oil (PKO). The problem that often occurs in this factory is that the quality of processed palm kernel is under the set standard of the company, especially palm kernel products, resulting in a loss for the company indirectly. To minimize the loss, the quality control must be conducted. The purpose of this research is to control the quality of palm kernel by using individual moving range (I-MR) chart. From the research result, it is found that the level of impurities in the palm kernel products still require control because the value was above the company's provision which is ≤ 6 while the research result was > 6.
