The Use of the Economic Production Quantity (EPQ) Method to Minimize Tebs Tea Production Costs (Case Study: PT. Sinar Sosro Deli Serdang)

Introduction

Inventory management is a crucial aspect of any production process, as it directly affects the cost and distribution of goods. Effective inventory control ensures that the right amount of goods is available at the right time, thereby minimizing losses and maximizing profitability. In this study, we will explore the application of the Economic Production Quantity (EPQ) method in minimizing Tebs Tea production costs at PT. Sinar Sosro Deli Serdang.

The Importance of Inventory Control

Inventory is a vital element in the production process, encompassing raw materials, goods in the process, and finished goods. Inventory imbalance, either in the form of excess or disadvantages, can cause significant losses to the company. Therefore, inventory control is essential to ensure the availability of goods in the right amount and on time. Proper inventory management can help companies avoid overstocking, reduce storage costs, and improve cash flow.

The Economic Production Quantity (EPQ) Method

The EPQ method is a mathematical model designed to determine the optimal production level of goods, thereby minimizing total inventory costs. This method considers various factors, including production costs and storage costs. The EPQ model is particularly useful in situations where production costs are high, and storage costs are significant.

Case Study: PT. Sinar Sosro Deli Serdang

In this study, the EPQ method was applied to determine the optimal production level of Tebs Tea products at PT. Sinar Sosro Deli Serdang. The calculation results showed that the optimal production rate for each Tebs Tea production cycle is 6,402.56 units, with optimal time intervals of 0.2013 months. The application of the EPQ method resulted in a significant reduction in production costs, reaching Rp. 59,378,435,392.27.

Additional Analysis and Explanation

The EPQ method focuses on determining the most efficient amount of production, so the costs incurred to produce and store goods are minimal. In this case study, it is essential to record that the difference in the cost of procuring Tebs Tea production inventory produced using the EPQ model compared to the production method commonly carried out by the company shows a significant difference. This demonstrates that the application of the EPQ method not only helps reduce costs but also increases the company's operational efficiency.

Advantages of Using the EPQ Model

One of the advantages of using the EPQ model is its ability to provide a clearer picture of when and how many products must be produced. This is very useful for managers in planning production and procurement of raw materials. Thus, companies can avoid overstocking or understanding that can be detrimental.

In addition, the application of this method can also have a positive impact on the company's cash flow. With lower production and storage costs, companies can allocate their budgets better for other purposes, such as marketing and development of new products.

Conclusion

The use of the Economic Production Quantity (EPQ) method in the context of PT. Sinar Sosro Deli Serdang shows how important inventory control is in increasing company profitability. Adopting this approach not only guarantees production efficiency but also supports business continuity in the long run. Through this study, it can be concluded that investment in a good inventory control system is very beneficial for companies in achieving optimal performance.

Recommendations

Based on the findings of this study, the following recommendations are made:

  1. Implement the EPQ method: PT. Sinar Sosro Deli Serdang should implement the EPQ method to determine the optimal production level of Tebs Tea products.
  2. Monitor and adjust: The company should continuously monitor and adjust the production level to ensure that it remains optimal.
  3. Invest in inventory control: The company should invest in a good inventory control system to ensure that the right amount of goods is available at the right time.

By implementing these recommendations, PT. Sinar Sosro Deli Serdang can minimize production costs, improve operational efficiency, and increase profitability.

Limitations of the Study

This study has several limitations, including:

  1. Limited data: The study was based on limited data, which may not be representative of the entire company.
  2. Simplification of assumptions: The study assumed that the production costs and storage costs are constant, which may not be the case in reality.
  3. Limited scope: The study focused on the application of the EPQ method in a single company, and its applicability to other companies is not clear.

Future Research Directions

Future research should focus on:

  1. Extending the scope: The study should be extended to other companies to determine the applicability of the EPQ method in different contexts.
  2. Improving the model: The EPQ model should be improved to take into account more complex factors, such as seasonality and demand fluctuations.
  3. Investigating the impact: The study should investigate the impact of the EPQ method on other aspects of the company, such as cash flow and employee productivity.

By addressing these limitations and future research directions, the study can provide more comprehensive insights into the application of the EPQ method in minimizing production costs.
