In response to increasing competition in the manufacturing sector, PT X—a copper busbar manufacturing company—implemented Lean Manufacturing supported by Value Stream Mapping (VSM) to improve production efficiency and reduce supply chain costs. This study utilizes VSM, Value Stream Analysis Tools (VALSAT), and Root Cause Analysis (5 Whys) to identify sources of waste and formulate improvement strategies. The analysis identified three dominant wastes: waiting time, product defects, and excess inventory. These were mainly caused by the lack of standardized material procedures, inadequate supporting equipment, and poor integration between the incoming inspection process and the Enterprise Resource Planning (ERP) system. To address these issues, the study proposes installing silica rolls, providing air wipers and flatness tools, developing standardized work instructions, and integrating Internet of Things (IoT) technology with the ERP system for real-time monitoring. As a result of implementing these solutions, PT X successfully reduced its defect rate from 6.23% to 1.32%, decreased lead time, and achieved notable savings in supply chain costs. The findings demonstrate that integrating Lean Manufacturing principles with VSM can effectively eliminate non-value-added activities, streamline production processes, and enhance overall competitiveness. This study reinforces the strategic value of Lean tools in continuous improvement initiatives within the manufacturing industry.

Fruits and vegetables are perishable food items that require special handling during both the receiving and storage processes. The purpose of this study is to investigate the implementation of fruit and vegetable receiving and storage processes in the kitchen of Hotel Mercure Surabaya Grand Mirama. This research employs two approaches: quantitative descriptive and qualitative. Data collection techniques include questionnaires, interviews, and documentation studies. The data analysis technique used is descriptive quantitative analysis, where questionnaire results are calculated using a percentage formula (%) and described using percentage interpretation criteria. Based on the findings, the implementation of fruit and vegetable receiving processes at Hotel Mercure Surabaya Grand Mirama shows that indicators for product freshness, material inspection, rejection of non-conforming materials, sorting, and washing are categorized as good. However, the indicator for material cleanliness falls under the fair category. Meanwhile, the implementation of storage processes, including storage temperature, storage facilities, storage inspection, and the application of the FIFO (First In First Out) storage method, demonstrates a very good criterion. Nevertheless, material separation received a good criterion, indicating room for further improvement to optimize storage management and ensure compliance with established standards.
