Introduction

PT Guna Kemas Indah, a company located in Tanjung Morawa, Medan, North Sumatra, is a leading manufacturer of various types of plastic cups, including Cening Cup, Cup Printing, and Lolly Cup. The company's main raw materials are Titro Propylenna 6531, Titanlene, and Afal, which are imported from outside the city. Despite its success in the plastic packaging industry, PT Guna Kemas Indah still uses traditional methods to determine production costs, which can lead to inaccurate cost allocation and distortion in the allocation of costs. This article aims to analyze the production costs of PT Guna Kemas Indah using the Activity Based Costing (ABC) approach, a method that focuses on activities that cause costs and uses a cost driver that is directly related to these activities.

Traditional Costing Methods and Their Limitations

Traditional costing methods, such as the absorption costing method, allocate costs evenly across departments or sections. However, this approach can lead to inaccurate cost allocation and distortion in the allocation of costs. As a result, companies may experience undercost or overcost on certain products. In the case of PT Guna Kemas Indah, the traditional costing method may not accurately reflect the true costs of production, leading to inaccurate decision-making and reduced competitiveness.

Activity Based Costing (ABC) Approach

The ABC approach is a method of costing that focuses on activities that cause costs and uses a cost driver that is directly related to these activities. This approach provides more accurate and relevant cost information for each product, allowing companies to make more informed decisions about production strategies, resource allocation, and selling prices. The ABC approach involves the following steps:

Identify activities: Identify the activities that cause costs, such as production, marketing, and distribution.
Assign cost drivers: Assign a cost driver to each activity, such as the number of units produced or the number of customers served.
Calculate costs: Calculate the costs associated with each activity using the cost driver.
Allocate costs: Allocate the costs to each product or department based on the cost driver.

Application of ABC at PT Guna Kemas Indah

The ABC approach was applied to PT Guna Kemas Indah to determine the production costs of each type of cup. The results of the calculation are as follows:

Clear Cup: Rp. 21/gr
Cup Printing: Rp. 12.07/gr
Cup Lolly: Rp. 34.23/gr

The results indicate a significant difference in the production costs of each type of cup, suggesting that the traditional costing method may have led to undercost or overcost on certain products.

Benefits of ABC at PT Guna Kemas Indah

The application of ABC at PT Guna Kemas Indah has several benefits, including:

More appropriate decision making: Accurate cost information allows companies to make more informed decisions about production strategies, resource allocation, and selling prices.
Increased efficiency: By understanding the most cost activities, PT Guna Kemas Indah can optimize the use of resources and reduce waste.
Increased competitiveness: The more accurate cost of production allows companies to set more competitive selling prices and increase competitiveness in the market.

Conclusion

The ABC approach provides a more accurate and relevant method of costing than traditional methods. By applying the ABC approach, PT Guna Kemas Indah can improve its efficiency, profitability, and competitiveness in the plastic packaging industry. The benefits of ABC include more appropriate decision making, increased efficiency, and increased competitiveness. While the application of ABC requires extra time and effort, the benefits obtained will be very significant in the long run.

Recommendations
