Introduction

Sludge separators are crucial tools in palm oil mills, responsible for separating mud (sludge) from palm oil. The existence of this machine is vital to maintain product quality and operational efficiency in the factory. This study aims to identify failures that occur in the sludge separator using two analytical methods, namely Fault Tree Analysis (FTA) and Root Cause Analysis (RCA). In addition, analysis of variance (ANOVA) and Reliability Block Diagram (RBD) will also be used to assess the level of reliability of the engine. The sludge separator machine analyzed is located in the PTPN IV Palm Oil Factory Adolina Business Unit, which was found that the engine suffered severe damage and often experienced problems. Therefore, good maintenance management becomes very important to support the productivity and efficiency of the system in each factory.

Understanding the Importance of Sludge Separator Maintenance

Machine failure in the sludge separator can have a negative impact on the production process, both in terms of quality and quantity. The inability of the engine to operate optimally can cause a buildup of sludge and contamination in the final product. The Fault Tree Analysis (FTA) method helps to map the relationship between various causes of failure, so that a clear picture can be obtained regarding existing risks. On the other hand, Root Cause Analysis (RCA) focuses on identifying the root causes of existing problems, which can be a crucial step in preparing an effective improvement plan.

In the analysis, the FTA technique will describe a tree diagram that shows the main failures and related causes. By analyzing this diagram, companies can identify critical factors that contribute to engine damage. Meanwhile, the RCA will involve techniques such as 5 Whys or Fishbone Diagram to find deeper root problems, not just symptoms that are seen.

The Role of Fault Tree Analysis (FTA) in Identifying Causes of Failure

Fault Tree Analysis (FTA) is a method used to identify the causes of failure in a system. It involves creating a tree diagram that shows the main failures and related causes. By analyzing this diagram, companies can identify critical factors that contribute to engine damage. FTA is a useful tool in identifying the root causes of failure, which can be used to develop an effective improvement plan.

The Role of Root Cause Analysis (RCA) in Identifying Root Causes of Failure

Root Cause Analysis (RCA) is a method used to identify the root causes of existing problems. It involves techniques such as 5 Whys or Fishbone Diagram to find deeper root problems, not just symptoms that are seen. RCA is a crucial step in preparing an effective improvement plan, as it helps to identify the underlying causes of failure.

Analysis and Results

From the results of the analysis conducted at the PTPN IV factory, found several main causes that caused failure in the sludge separator. Some of them include damage to mechanical components, lack of regular maintenance, and problems in the operational process. By using variance analysis (ANOVA), it can be seen the effect of each cause of the engine failure rate. This result will provide deeper insight about which parts need to be improved or optimized.

The Use of Analysis of Variance (ANOVA) in Identifying the Effect of Each Cause

Analysis of Variance (ANOVA) is a statistical method used to identify the effect of each cause on the engine failure rate. By using ANOVA, it can be seen which parts need to be improved or optimized. This result will provide deeper insight about the causes of failure and help to develop an effective improvement plan.

The Use of Reliability Block Diagram (RBD) in Assessing the Reliability of the Sludge Separator System

Reliability Block Diagram (RBD) is a method used to assess the reliability of the sludge separator system. With this diagram, management can evaluate the probability of the success of machine functions within a certain period of time. The results of the RBD analysis show that if some key components are not functioning, there will be a direct impact on the whole process of separation.

Conclusion

Through the use of the Fault Tree Analysis and Root Cause Analysis method, the company is expected to better understand the cause of failure in the sludge separator and take appropriate improvement action. Proper and well-scheduled maintenance can minimize damage, thereby increasing factory productivity and efficiency. With this comprehensive analysis, PTPN IV can improve their maintenance management system and ensure that important machines operate well, which in turn will have a positive impact on production results.

Recommendations for Future Research

Based on the results of this study, several recommendations for future research can be made. Firstly, further research can be conducted to identify the root causes of failure in other machines in the factory. Secondly, the use of other analytical methods, such as Failure Mode and Effects Analysis (FMEA), can be explored to identify the causes of failure in the sludge separator. Finally, the development of a maintenance management system that incorporates the results of this study can be explored to improve the productivity and efficiency of the factory.

Limitations of the Study

This study has several limitations. Firstly, the analysis was conducted on a single machine in the factory, which may not be representative of the entire factory. Secondly, the use of only two analytical methods, FTA and RCA, may not be sufficient to identify all the causes of failure. Finally, the development of a maintenance management system that incorporates the results of this study may require further research and development.

Future Directions

Based on the results of this study, several future directions can be explored. Firstly, the development of a maintenance management system that incorporates the results of this study can be explored to improve the productivity and efficiency of the factory. Secondly, further research can be conducted to identify the root causes of failure in other machines in the factory. Finally, the use of other analytical methods, such as FMEA, can be explored to identify the causes of failure in the sludge separator.
