Oct 13, 2025 by wbrum.org 13 views

Introduction

CV. Nina Bakery, a company engaged in the field of bread production, faces the problem of frequent damage to roll machines, resulting in decreased production and operational efficiency. To overcome this problem, an in-depth analysis is needed to find the root cause of the engine damage and solutions. This study aims to analyze the level of effectiveness of the roll machine using the Overall Equipment Effectiveness (OEE) method and Failure Mode and Effect Analysis (FMEA) to identify potential failure modes and their impact on the roll machine.

The Problem of Roll Machine Damage in CV. Nina Bakery

The roll machine is a crucial component in the bread production process, responsible for shaping and rolling the dough into the desired shape. However, the frequent damage to the roll machine has resulted in a significant decrease in production and operational efficiency. The damage to the roll machine is caused by various factors, including machine, human, methods, and environmental factors.

Analysis of Roll Machine Effectiveness using OEE Method

The OEE method is a widely used technique to measure the effectiveness of equipment in a production process. The OEE value is calculated by multiplying the availability, performance efficiency, and product quality level of the equipment. The analysis of the roll machine effectiveness using the OEE method showed an average OEE value of 52.46% during the October 2022-May 2023 period. This figure is below the standard, indicating the need for improvement efforts.

The analysis of the roll machine effectiveness using the OEE method also showed that the roll machine has an average availability value of 85.90%, performance efficiency of 63.31%, and product quality level of 96.46%. The results indicate that the roll machine is not operating at its optimal level, resulting in decreased production and operational efficiency.

Analysis of Six Big Losses

The Six Big Losses analysis is a technique used to identify the main causes of losses in a production process. The analysis of the roll machine showed that the largest loss comes from reduced speed (reduced speed losses) of 59.72%. This is caused by damage to the engine that often occurs, which ultimately affects the effectiveness of the roll machine.

Causal Diagram Analysis

To find the root cause of the speed decrease, this study uses a causal diagram. The results show several factors that cause the speed decrease, including machine, human, methods, and environmental factors. The causal diagram analysis helps to identify the potential causes of the speed decrease and provides a basis for further analysis.

FMEA Analysis

The FMEA analysis is a technique used to identify potential failure modes and their impact on the roll machine. The analysis results show that the use of spare parts that do not match the specifications has a RPN value (risk priority number) of 336. This has the potential to cause engine damage and stop the production process.

Recommendations for Improving Roll Machine Effectiveness

Based on the results of the analysis, corrective action is needed to increase the effectiveness of the roll machine. Here are some recommendations:

Preventive Engine Maintenance

Periodic preventive maintenance will help prevent engine damage and increase the use of its use.
Regular maintenance will help to identify potential problems and take preventive action.

Ensuring the Use of Components and Spare Parts According to Specifications

The use of components according to specifications will minimize the risk of engine damage and increase their reliability.
Ensuring the use of spare parts that match the specifications will help to prevent engine damage and increase the effectiveness of the roll machine.

Improving Quality and Operational Standards

Improving quality and operational standards will help minimize human errors and improve the efficiency of the production process.
Implementing quality control measures will help to identify potential problems and take preventive action.

Implementing an Effective Monitoring and Control System

The application of an effective monitoring and control system will help detect potential problems and take preventive action.
Implementing a monitoring and control system will help to identify potential causes of engine damage and take corrective action.

Conclusion

The analysis of the roll machine effectiveness using the OEE method and FMEA analysis has identified several areas for improvement. The recommendations provided in this study aim to increase the effectiveness of the roll machine, minimize losses due to engine damage, and increase the efficiency of the overall production process. By implementing these recommendations, CV. Nina Bakery can improve the efficiency of the roll machine and increase the overall production process.

Future Research Directions

This study has identified several areas for future research, including:

Conducting a more in-depth analysis of the causal diagram to identify the root cause of the speed decrease.
Conducting a more detailed analysis of the FMEA results to identify potential failure modes and their impact on the roll machine.
Implementing a monitoring and control system to detect potential problems and take preventive action.
