Optimizing Manufacturing Systems: A Study on the Measurement of Overall Equipment Effectiveness (OEE) and Failure Mode and Effect Analysis (FMEA) at PT. Perkebunan Nusantara II Kwala Hadu Sugar Factory

Introduction

In today's competitive manufacturing landscape, achieving high production targets is crucial for the success of any organization. One key factor that contributes to a company's ability to meet its production targets is the effectiveness of its production machines. At PT. Perkebunan Nusantara II Kwala Hadu Sugar Factory, machines and production equipment play a vital role in supporting the smooth production process. Therefore, proper and sustainable maintenance is essential to ensure that these machines function optimally. In this study, we focus on calculating the effectiveness value of the Cane Cutter machine used in the production process in the sugar factory.

The Importance of OEE and FMEA in Manufacturing Systems

Overall Equipment Effectiveness (OEE) is a widely used metric that measures how effective a machine operates based on the time available for production, speed, and quality of the product produced. OEE analysis consists of three main components: availability, performance, and quality. Availability measures how often the machine is available for operation, performance measures how fast the engine runs compared to the maximum speed, and quality measures the number of products that meet quality standards compared to the total products produced.

Failure Mode and Effect Analysis (FMEA) is another important method used to identify potential damage that can occur in machines. FMEA helps teams understand the types of failures that may occur, their impact on the production process, and preventive steps that can be taken to minimize these risks.

Calculating OEE Values at PT. Perkebunan Nusantara II Kwala Hadu Sugar Factory

In this study, we used the OEE method to calculate the effectiveness value of the Cane Cutter machine used in the production process in the sugar factory. The data used in this analysis was taken from the production process from February to July 2015. The calculation results show that the average Cane Cutter engine OEE value reaches 43% during that period. This low OEE value indicates that there are significant problems in engine performance, which can be caused by several factors such as damage, stop time, or productivity that is not optimal.

Deeper Analysis of OEE and FMEA

In more depth, OEE analysis consists of three main components:

Availability: Measuring how often the machine is available for operation.
Performance (Performance): Measuring how fast the engine runs compared to the maximum speed.
Quality (quality): Measuring the number of products that meet quality standards compared to the total products produced.

These three components need to be analyzed continuously to understand the source of the problem that causes low OEE values. For example, if the availability of the engine is low, the cause needs to be examined, whether due to unjected maintenance or engine damage.

In addition, the application of the FMEA method is very important to identify the potential damage that can occur in the machine. FMEA helps the team to understand the types of failures that may occur, their impact on the production process, and preventive steps that can be taken to minimize these risks.

Action Recommendations

Based on the results of OEE and FMEA analysis, some of the recommended actions to increase the effectiveness of the machine at PT. Nusantara Plantation II include:

Routine Maintenance Schedule: Carry out regular maintenance to ensure that all machines are in optimal condition.
Employee Training: Provide training to machine operators so that they better understand how to care for and operate the machine properly.
Investment in Technology: Considering replacing an outdated or inefficient machine with a newer and more effective one.
Monitoring and Measurement: Applying sophisticated monitoring systems to detect problems early and avoid unwanted downtime.

By applying these steps, it is expected that the OEE value can increase, which in turn will contribute to the optimization of the manufacturing system at PT. Perkebunan Nusantara II Kwala Hadu Sugar Factory and Achievement of Better Production Targets.

Conclusion

In conclusion, the measurement of OEE and FMEA values is a crucial step in optimizing the manufacturing system at PT. Perkebunan Nusantara II Kwala Hadu Sugar Factory. By analyzing the effectiveness value of the Cane Cutter machine used in the production process in the sugar factory, we can identify the source of the problem that causes low OEE values. The application of FMEA method is also important to identify the potential damage that can occur in the machine. By implementing the recommended actions, it is expected that the OEE value can increase, which in turn will contribute to the optimization of the manufacturing system and Achievement of Better Production Targets.

Recommendations for Future Research

Based on the findings of this study, we recommend the following for future research:

Conduct a more in-depth analysis of OEE and FMEA: Conduct a more in-depth analysis of OEE and FMEA to identify the root causes of low OEE values and potential damage that can occur in the machine.
Develop a more effective maintenance schedule: Develop a more effective maintenance schedule that takes into account the specific needs of each machine and production process.
Invest in technology: Invest in technology that can help detect problems early and avoid unwanted downtime.
Provide training to machine operators: Provide training to machine operators so that they better understand how to care for and operate the machine properly.

By implementing these recommendations, it is expected that the OEE value can increase, which in turn will contribute to the optimization of the manufacturing system and Achievement of Better Production Targets.
