Reducing tyre scrap blister under tread with PDCA approach: A case study in manufacturing industry

Abstract

Productivity by economists determines productivity as "output ratio" relative to "physical input". It is usually associated with the industry as a whole in the sector within the economy. One of the decreasing productivity factors is the value of scrap products.The purpose of this study is to reduce the amount of scrap that occurs to increase productivity tyreThe value of the tire produced by the company is high enough and the highest value percentage due to Scrap Blister Under Tread (BL / UT), and this process occurs in TBM (Tire Building Machine). This study will analyze both the actual data and the data with the PDCA concept (Plan Do Check Action). The result of this study is that the BL / UT scrap tire decreased from 0.141% (January-April 2017) to 0.016% (Sept 2017) or down by 86% and the average after-repair output increased 8.5% from baseline (January-April 2017) besides giving an impression on QCDSM (Quality, Cost, Delivery, Safety, Morale).
