Abstract

Rework in the rubber compounding area is very important to be improved for continuity the supply compound to the next process by achieving a key performance indicator over from target of 19,624 ppm. The rework activities caused by the quality out-of-standard compounds, including re-mixing and blend 10%, to find the root of the problem using a fishbone diagram and decision making to determine the priority scale using the Analytical Hierarchy Process method. The criteria used are based on compound properties including modulus, hardness, specific gravity, and the cost for rework criteria are based on energy consumption and waiting time. The alternative for solution of reduce rework is best sequence of produce mixture. In calculations using AHP, the weight values obtained for the criteria for hardness (0.198), modulus (0.238), specific gravity (0.181), energy consumption (0.174), and waiting time (0.208). The weights for the alternatives obtained are Mixture 1 (0.226), Mixture 2 (0.335), and Mixture 3 (0.439). Using priority on the criterion that has the highest weight is Modulus with a value of 0.238 and the alternative that has the highest Mixture 3 weight of 0.439, the number of rework has been reduce 45.1% and the cost rework is 59.8%.
