Analysis of the Number of Optimal Workforce Based on Work Methods at the Wooden Sorting Station at PT Bukit Intan Abadi

Introduction

PT Bukit Intan Abadi, a wood processing factory located in Medan Deli District, specializes in the production of sawn wood such as Finger Joint Laminating Board (FJLB) and Plywood. The factory's production process involves various stages, including the wooden sorting station, where wood is sorted according to size. However, the wooden sorting station at PT Bukit Intan Abadi faces significant challenges due to inappropriate work methods, resulting in severe workload for workers and daily targets that are often not achieved. In this situation, 26 workers are assigned to sort wood according to size, with the volume of wood that enters up to 100 m³ per day, while the sorting capacity that can be achieved only ranges from 50-70 m³ per day.

The Challenges Faced by PT Bukit Intan Abadi

The main problems faced by PT Bukit Intan Abadi are related to less efficient work methods, hot working conditions, and daily targets that are too high. The current work methods used by the workers at the wooden sorting station are not only inefficient but also cause a significant imbalance between the number of workers and the existing workload. The workload received by each worker is 117.83% with the current work method, which shows an overload (excess) workload. This situation not only affects the productivity of the factory but also has a negative impact on the welfare of the workers.

The Importance of Time Study Method and Stopwatch Time Study

To find solutions to this problem, the time study method and stopwatch time study are used to analyze the workload and find the optimal number of workers. The time study method is a technique used to measure the time taken to complete a specific task or activity, while the stopwatch time study is a method used to record the time taken to complete a task or activity. By using these methods, the factory can identify the most efficient work methods and the optimal number of workers required to achieve the daily targets.

The Results of the Analysis

Based on the results of the calculations carried out, the workload received by each worker is 117.83% with the current work method, which shows an overload (excess) workload. Meanwhile, if you use the recommended work methods, the workload is 77.33%, which is classified in the category of underloading workload. From this, it can be concluded that there is a significant imbalance between the number of workers and the existing workload.

The Optimal Number of Workforce

The results of the analysis show that the optimal number of workforce with the current work methods is 31 people, while the recommended work methods are only 21 people. The decline in the number of labor can be interpreted that the application of more effective methods not only reduces workload, but also optimizes the use of existing human resources.

Conclusion and Recommendations

In order to achieve a more efficient production target, it is important for PT Bukit Intan Abadi to apply better work methods. With the recommended work methods, companies can avoid the necessity to recruit additional workers, which will certainly reduce operational costs. In addition, the improvement of work methods will also create a more conducive work environment and reduce the risk of fatigue for workers.

Overall, optimizing the number of workforce and work methods will contribute not only to the achievement of production targets, but also to the welfare of workers and the company's operational effectiveness. The balance between workload and the ideal number of workers must be the main focus in each industry, especially in the wood processing sector that has high demands.

The Benefits of Optimizing Workforce and Work Methods

Optimizing the number of workforce and work methods will have several benefits for PT Bukit Intan Abadi. Firstly, it will improve the productivity of the factory by reducing the workload of each worker. Secondly, it will reduce the operational costs of the factory by avoiding the necessity to recruit additional workers. Thirdly, it will create a more conducive work environment and reduce the risk of fatigue for workers.

The Challenges of Implementing New Work Methods

However, implementing new work methods can be challenging for PT Bukit Intan Abadi. Firstly, it requires a significant investment in training and development for the workers. Secondly, it requires a change in the mindset of the workers and the management. Thirdly, it requires a significant change in the work processes and procedures.

The Way Forward

In order to overcome the challenges of implementing new work methods, PT Bukit Intan Abadi needs to take a proactive approach. Firstly, it needs to invest in training and development for the workers. Secondly, it needs to communicate effectively with the workers and the management. Thirdly, it needs to monitor and evaluate the progress of the implementation of the new work methods.

Conclusion

In conclusion, optimizing the number of workforce and work methods is crucial for PT Bukit Intan Abadi to achieve a more efficient production target. The results of the analysis show that the optimal number of workforce with the current work methods is 31 people, while the recommended work methods are only 21 people. The decline in the number of labor can be interpreted that the application of more effective methods not only reduces workload, but also optimizes the use of existing human resources.

Recommendations

Based on the results of the analysis, the following recommendations are made:

PT Bukit Intan Abadi should implement the recommended work methods to optimize the number of workforce and work methods.
The factory should invest in training and development for the workers to improve their skills and knowledge.
The factory should communicate effectively with the workers and the management to ensure a smooth implementation of the new work methods.
The factory should monitor and evaluate the progress of the implementation of the new work methods to ensure that the desired outcomes are achieved.

Limitations of the Study

This study has several limitations. Firstly, the study only focuses on the wooden sorting station at PT Bukit Intan Abadi. Secondly, the study only uses the time study method and stopwatch time study to analyze the workload and find the optimal number of workers. Thirdly, the study does not take into account the impact of other factors such as technology and equipment on the workload and the optimal number of workers.

Future Research Directions

Future research should focus on the following areas:

The impact of technology and equipment on the workload and the optimal number of workers.
The effect of different work methods on the workload and the optimal number of workers.
The impact of other factors such as training and development on the workload and the optimal number of workers.
