PDCA - Eight Steps Implementation to Increasing Productivity in the Production of Compound Tread Off Road TBR

This study aims to implement the PDCA-eight steps to improve the productivity of the Tread Off Road TBR compound at Tire Manufacturer. Implementation begins with determining the theme of improvement with Pareto diagram tools to select production machines for improvement. The second step, set the target of improvement with histogram data. The third step, use a checksheet to find all possible causes during the observation and divide it into 4 categories: Man, Machine, Material & Method. The fourth step is to analyze the root of the problem using the fishbone diagram. The fifth and sixth steps, Plan & implement Corrective Actions using the 5W + 1H method. The seventh stage, evaluation of the results using the Pareto diagram for productivity and SPC for evaluation of compound quality. The Pareto diagram shows an increase in productivity of 31.15% and quality is maintained with an average CPK of 2.33. The last stage is to standardize and determine the next plan. The results of the implementation in this study indicate that this implementation can increase production productivity.
