Abstract

The increasingly competitive conditions in the manufacturing industry require companies to continuously improve product quality and production process efficiency in order to maintain customer trust and loyalty. At UD Machillah Jaya, one of the ongoing problems is waste, particularly in the form of long waiting times (delay). This issue is caused by large-sized iron raw materials that require longer cutting times, thus slowing down subsequent assembly processes. As a result, production efficiency decreases and product quality consistency becomes unstable. To address this issue, an in-depth analysis of non-value added activities particularly necessary non-value added activities is required. This study aims to identify and reduce such inefficient activities within the production process. Based on data processing results, it was found that the largest proportion of time was spent on operational activities (88.02%), followed by inspection (0.34%), while delay accounted for 9.01%. This significant percentage of delay is considered a major factor slowing down the production process, likely due to inadequate material handling equipment being used.Keywords: kaizen, lean manufacturing, value stream mapping
