摘要

XYZ公司是一家从事棕榈仁(CPKO)加工的公司。CPKO分为粗棕榈仁油苷(CPKOL)和粗棕榈仁硬脂苷(CPKST)。CPKST的IV质量(碘值)质量标准存在差异,影响了销售价格和消费者需求。公司对IV值的测定范围为5-7。对IV值进行分组和数据收集,为期3个月,然后采用I-MR控制图、过程能力和因果图的统计质量控制(SQC)方法对数据进行分析。本研究旨在分析IV CPKST不符合公司标准的工艺能力。数据处理结果表明,部分CPKST IV值超出控制范围,在UCL 0.70和LCL 0范围内移动,个体在UCL 7.33和LCL 6.18范围内移动,过程能力较好,在6.37和1范围内进行了因果分析。根据鱼骨图分析结果,找出了造成质量不符合的因素,包括人、机、法三个方面。有必要在现有法规的基础上努力保持和维护产品质量。

Analisis Proses Kapabilitas Iodine Value (IV) Crude Palm Kernel Oil Stearin (CPKST) Di Pabrik Kelapa Sawit
PT. XYZ, is a company engaged in the processing of palm kernel (CPKO). CPKO was separated into CPKOL (crude palm kernel olein) and CPKST (crude palm kernel stearin). There is a discrepancy in the quality standard of IV quality (Iodine Value) at CPKST which affects the selling price and consumer demand. Determination of the value of IV by the company ranges from 5-7. Grouping and data collection of IV values was carried out for 3 months, then the data was analyzed using statistical quality control (SQC) methods of I-MR control charts, process capabilities, and cause-and-effect diagrams. This study aims to analyze the process capability of IV CPKST which is not in accordance with company standards. The results of data processing show that some CPKST IV values are outside the control limits, moving ranges with UCL 0.70 and LCL 0, individuals with UCL 7.33 and LCL 6.18, and process capability is said to be good with a value range of 6.37 and 1 A causal analysis was performed using a fishbone diagram. Based on the results of the fishbone diagram analysis, the factors of quality non-compliance are found in humans, machines and methods. It is necessary to make efforts to maintain and maintain product quality based on existing regulations.
