Application Of The Economic Production Quantity (EPQ) Method To Calculate The Level Of Optimal Coffee Beans Production Control (Case Study: Baitul Qiradh Baburrayyan Cooperative)
Introduction
Inventory management is a crucial aspect of the production process, as it directly affects the costs and distribution of goods. Whether it's raw materials, goods in the process, semi-finished goods, or finished goods, improper inventory management can result in significant losses for the company. The advantages or disadvantages of inventory can cause the loss of opportunities to achieve profits that should be obtained. Therefore, it is essential to implement effective inventory control.
In this study, we focus on applying the Economic Production Quantity (EPQ) method in calculating the level of optimal production control for coffee in the Baitul Qiradh Baburrayyan Cooperative. The EPQ method is used to determine the most efficient level of production, so that the total inventory costs can be minimized. The results showed that the optimal level of coffee production for each cycle was 281,591.27 kg with an optimal time interval of 1.59 months. The difference in the cost of procuring coffee inventory produced using the EPQ model reaches Rp2,124,068,386.20 when compared to the traditional calculation method applied by the company.
The Importance of Inventory Control
Efficient inventory control is very important for companies in maintaining operational stability and profit. The EPQ model not only helps the company in calculating the optimal amount of production, but also reduces unnecessary inventory costs. In this study, the EPQ method was proven to be able to provide better alternatives compared to conventional methods, which often ignore important variables in the production process.
Through the use of EPQ, the Baitul Qiradh Baburrayyan Cooperative can optimize their production cycle by minimizing procurement and storage costs. This will certainly have positive implications for the company's cash flow, where the costs incurred can be allocated for other investments. In the context of increasingly fierce market competition, the application of this method is a necessity for business people, especially in the agricultural sector and coffee production.
The Benefits of EPQ Method
The EPQ method offers several benefits to companies, including:
- Reduced Inventory Costs: The EPQ method helps companies to minimize unnecessary inventory costs by determining the optimal level of production.
- Improved Cash Flow: By minimizing procurement and storage costs, companies can allocate their resources for other investments.
- Increased Operational Efficiency: The EPQ method helps companies to optimize their production cycle, leading to increased operational efficiency.
- Better Decision Making: The EPQ method provides companies with accurate and reliable data, enabling them to make informed decisions.
Case Study: Baitul Qiradh Baburrayyan Cooperative
The Baitul Qiradh Baburrayyan Cooperative is a coffee producer that has been using the traditional calculation method to determine their production levels. However, this method has resulted in significant losses for the company. In this study, we applied the EPQ method to determine the optimal level of coffee production for the cooperative.
The results showed that the optimal level of coffee production for each cycle was 281,591.27 kg with an optimal time interval of 1.59 months. The difference in the cost of procuring coffee inventory produced using the EPQ model reaches Rp2,124,068,386.20 when compared to the traditional calculation method applied by the company.
Conclusion
The application of the EPQ method is a necessity for companies in the agricultural sector and coffee production. The method offers several benefits, including reduced inventory costs, improved cash flow, increased operational efficiency, and better decision making. In this study, we applied the EPQ method to determine the optimal level of coffee production for the Baitul Qiradh Baburrayyan Cooperative.
The results showed that the EPQ method can provide better alternatives compared to conventional methods, which often ignore important variables in the production process. We hope that this research can be a reference for other companies in adopting the best practice in controlling inventory and improving their production process.
Recommendations
Based on the results of this study, we recommend that companies in the agricultural sector and coffee production adopt the EPQ method to determine their production levels. The method can help companies to minimize unnecessary inventory costs, improve their cash flow, and increase their operational efficiency.
We also recommend that companies conduct a thorough analysis of their production process to identify areas for improvement. This can help companies to optimize their production cycle and reduce their costs.
Limitations of the Study
This study has several limitations, including:
- Limited Data: The study was conducted using data from a single company, which may not be representative of other companies in the industry.
- Simplifying Assumptions: The study made several simplifying assumptions, including the assumption that the production process is a continuous process.
- Limited Scope: The study focused on a single company and a single product, which may not be representative of other companies and products in the industry.
Future Research Directions
Future research should focus on:
- Validating the EPQ Method: Future research should validate the EPQ method using data from multiple companies and products.
- Improving the EPQ Model: Future research should improve the EPQ model by incorporating additional variables and assumptions.
- Applying the EPQ Method to Other Industries: Future research should apply the EPQ method to other industries, such as manufacturing and retail.
By addressing these limitations and future research directions, we can further develop the EPQ method and its applications in inventory management.
Introduction
The Economic Production Quantity (EPQ) method is a widely used technique in inventory management to determine the optimal level of production.
