QUALITY CONTROL ANALYSIS WITH STATISTICAL QUALITY CONTROL (SQC) AND FAILURE METHODSMODE EFFECT ANALYSIS (FMEA) ON THE PRODUCTION OF ZA PLUS FERTILIZER

Abstract

PT.XYZ is an industrial logistics company, one of whose divisions is warehousing and MBU which serves fertilizer bagging. as for the problems that occur at PT.XYZ is the bagging of fertilizers that still occur defects. The purpose of this study is to determine the percentage of defects that occur most often and the factors that cause defects. as well as provide suggestions for improving the quality of fertilizer bagging. The methods used in this research are Statistical Quality Control (SQC) and Failure Mode Effect Analysis (FMEA). SQC tools are check sheet, pareto diagram, control map, and fishbone diagram. Then continue the FMEA analysis for proposed corrective actions. Based on the results of research on Statistical Quality Control (SQC), it is known that the most dominant bagging defects are tearing defects (58%), then stitching defects (27%), defects in weighing less (15%). Based on the results of research on Failure Mode Effect Analysis (FMEA), it is known that the cause of the highest problem with RPN100 is the type of tearing defect with the cause of less carefulness during the process of putting fertilizer on the pallet. The recommendation for improvement proposals to overcome this problem is to provide work procedure training to employees so that employees understand the work procedures at PT.XYZ.
