Abstract

Calibration laboratories play an important role in ensuring the accuracy of measuring instruments used in various industries. However, operational activities in this laboratory are not free from risks, which can have an impact on operator safety and work efficiency. This case study conducted at the PT XYZ calibration laboratory aims to identify, analyze, and provide mitigation proposals for operational risks using an integrated Failure Mode and Effect Analysis (FMEA) and Root Cause Analysis (RCA) approach. Data collection is done through direct observation and interviews with operators and laboratory leaders, followed by analysis using FMEA to determine risk priorities based on the Risk Priority Number (RPN) value. Furthermore, RCA through Ishikawa diagram was used to find the root causes of the main risks. The results identified two prioritized risks, namely electrocution and mental fatigue. Proposed mitigations include occupational safety training, periodic inspections, installation of dehumidifiers, workload adjustments, and application of the “5R (Cleanliness, Health, Safety, Order, and Beauty)” work principles. This case study demonstrates that the application of integrated methods can provide a comprehensive solution for managing operational risks in calibration laboratories. The outputs of this case study include practical recommendations to improve work safety and operational efficiency, which are expected to have a positive impact on the company in the long term.

Abstract

Inefficient warehouse operations often generate various forms of waste, including excessive waiting times, unnecessary transportation, and redundant activities, which ultimately increase lead times and reduce operational performance. Despite the critical role of finished feed product warehouses in maintaining supply chain responsiveness, studies addressing waste reduction in this context remain limited. This study aims to identify non-value-added activities in the finished feed product warehouse process and propose improvement strategies to enhance warehouse efficiency using a Lean Warehouse approach. The study integrates Value Stream Mapping (VSM), Value Stream Analysis Tools (VALSAT), fishbone diagram analysis, and the 5W+1H method to systematically identify, analyze, and eliminate waste within warehouse operations. The findings reveal that the current warehouse process has a total lead time of 447 minutes. Following the implementation of the proposed improvements, the future-state lead time is reduced to 269 minutes, representing a 39.8% reduction. In addition, Process Cycle Efficiency (PCE) improves from 20.81% to 34.57%, indicating a 13.76 percentage-point increase in operational efficiency. The identified improvements primarily address delays, excessive movement, and procedural redundancies in the warehouse flow. These results demonstrate that the Lean Warehouse approach provides an effective framework for minimizing waste and improving the performance of finished feed product warehouses. The study contributes practical insights for warehouse managers seeking to enhance operational efficiency and supports the broader application of lean principles in warehousing environments.
