The Application of Lean Maintenance to Reduce Waste on the Production Floor at PT. Growth Sumatra Industry

Introduction

In today's competitive business landscape, companies are constantly seeking ways to improve their efficiency and productivity. One of the key areas of focus is maintenance, as it plays a critical role in ensuring the smooth operation of machinery and equipment. However, many companies still rely on traditional maintenance approaches that can lead to waste, downtime, and lost productivity. This is particularly true for PT. Growth Sumatra Industry, a steel processing company that has been grappling with high waste levels in its maintenance process. In this article, we will explore the challenges faced by PT. Growth Sumatra Industry and how the application of Lean Maintenance can help reduce waste and improve overall production efficiency.

Challenges and Solutions

Waste in the maintenance process at PT. Growth Sumatra Industry is a significant challenge that affects time and productivity. The company's current maintenance system is based on the Corrective Maintenance approach, which means that repairs are only done when the engine is dead. This approach can lead to significant losses in production opportunities, making it essential to adopt a more proactive and efficient maintenance approach. Lean Maintenance is a methodology that aims to eliminate waste and improve the effectiveness of maintenance activities. By applying Lean Maintenance, PT. Growth Sumatra Industry can identify various types of existing waste, calculate the time required for maintenance activities before and after the application of improvements, and provide continuous improvement recommendations.

The Root of the Problem

To address the challenges faced by PT. Growth Sumatra Industry, it is essential to understand the root causes of waste in the maintenance process. This can be achieved through root analysis of the causes of the problem using techniques such as root cause analysis and Five Why (5WHY). By identifying the main causes and looking for the right solution, more effective improvement steps can be taken. For instance, if the root cause of waste is identified as a lack of maintenance planning, the solution could be to implement a maintenance planning system that ensures regular maintenance activities are scheduled and executed.

The Results of the Application of Lean Maintenance

The application of Lean Maintenance at PT. Growth Sumatra Industry has yielded significant results. Based on the results of the analysis conducted through Value Stream Mapping, there is a significant increase in maintenance efficiency in various engine components. For example, efficiency in the Remis Packing component increased from 27.78% to 42.01%, while the shaft or shaft component increased from 25% to 38.46%. In addition, the application of Lean Maintenance has succeeded in reducing total waste. Before repair, Waste Activity shows a high value, but after the application of waste reduction of 50%, the value of the Waste volume is reduced to:

Waste Motion: 34%
Waste Process: 2%
Waste Defect: 7%
Waste Waiting: 7%

Comparison between Current State Map and Future State Map

The comparison between current state map and Future State Map shows a significant increase in efficiency in the process of repairing the engine after the implementation of Lean Maintenance. This indicates that the application of Lean Maintenance has been successful in reducing waste and improving overall production efficiency.

Conclusion

The application of Lean Maintenance at PT. Growth Sumatra Industry has not only succeeded in reducing waste but also increasing overall production efficiency. By identifying and analyzing various types of waste, companies can make sustainable improvements. The use of appropriate analysis methods such as Root Causes Analysis and 5Why is a very valuable tool in this process. With the right steps, PT. Growth Sumatra Industry can achieve an increase in productivity and efficiency, having a positive impact on the sustainability of companies in the steel processing industry.
