Abstract

This research aims to 1) find out the cause of yellow tofu quality rejection by distributor agents in the supply chain, 2) know the comparison of rejection by the distributor agent pre-implementation and post-implementation of DMAIC methodology, 3) know the decrease in rejection by distributor agents in the supply chain. Research methods use the DMAIC methodology. The DMAIC method as the basis for determining the percentage value decreased rejection of yellow tofu products carried out by the distributor agent. The implementation of this research as an effort to provide the value of minimization of the type of rejection that occurs. This research resulted in 1) the cause of yellow tofu quality rejection by distributor agents in the supply chain is the presence of faded, watery, easily destroyed, bantat, torn 10%, torn 25%, smells sour and less chewy, 2) the comparison of rejection by the distributor agent pre-implementation and post-implementation of DMAIC methodology is 34% compared to 18%, 3) decreased rejection by distributor agents in the supply chain post DMAIC methodology by 16%. The three conclusions of this study are in accordance with the goals achieved. Consistent application of DMAIC methodology may provide more significant declines. The implications of this study compare the pre and post DMAIC methodology in the first, second, and third.

Abstract

The fierce competition of the global industry, operational efficiency is crucial for a company's competitiveness, and optimal facility layout can reduce production costs and accelerate cycle times. From-to charts are used to evaluate and optimise material or product flow. The From-To-Chart method is a traditional way to review and improve material or product flow. Its primary focus is to identify and measure material movement within the factory work area. Based on an initial analysis of the radiator seal production flow at PT. XYZ, efficiency remains low. Initial forward efficiency stands at 74.25%, below the optimal target of 75%. Meanwhile, backward efficiency reaches 25.75%, indicating significant unnecessary and repetitive material movement. This situation arises because certain areas, such as the laboratory and NMI zone, are visited more than once during a single production cycle. The analysis results show an improvement from 74.25% to 98.01%. Its primary function is to identify and calculate material movement moments within the industrial layout, thereby enhancing efficiency and effectiveness during operational time.
