Comparison of Stepping Stone Methods and Revised Distribution Methods (RDI) to Minimize Distribution Costs: Case Study of PT. Mega Eltra Medan Branch

Introduction

The problem of transportation is a significant challenge that companies face in the process of distributing goods. In the operational context of a company, product distribution to various regions requires a small amount of transportation costs. Therefore, companies need to make careful planning to ensure that the costs incurred are as efficient as possible, without sacrificing service quality. This is particularly true for PT. Mega Eltra, a company engaged in trade, especially local trade, which has branches in Medan involved in the distribution of Semen Padang products to several regions in North Sumatra Province.

Background

PT. Mega Eltra, as a company engaged in trade, has a significant role in the distribution of goods in North Sumatra Province. The company's operational context requires careful planning to ensure that the costs incurred are as efficient as possible, without sacrificing service quality. In this context, the company faces a significant challenge in the process of distribution of goods, which requires a small amount of transportation costs. Therefore, the company needs to make careful planning to ensure that the costs incurred are as efficient as possible.

Problem Statement

Literature Review

Several methods have been proposed to solve transportation problems, including the Vogel's Approximation (VAM) method, the Stepping Stone method, and the Revised Distribution (RDI) method. The Vogel's Approximation (VAM) method is a technique used to find the initial solution to transportation problems. The Stepping Stone method is a technique used to find optimal solutions to transportation problems by analyzing existing paths and determining whether there are more efficient alternative routes. The Revised Distribution (RDI) method is a more complex approach that also aims to find optimal solutions by considering all related distribution routes and costs.

Methodology

This study applied several methods, including the Vogel's Approximation (VAM) method to find the initial solution, as well as the Stepping Stone and Revised Distribution (RDI) method to find the optimal solution. The results of the calculations carried out showed that the Stepping Stone method produces transportation costs of Rp. 351,845,000. As a comparison, the RDI method produces higher transportation costs, which is Rp. 361,850,000.

Analysis of Stepping Stone and RDI Methods

Stepping Stone Method

The Stepping Stone method is a technique used to find optimal solutions to transportation problems by analyzing existing paths and determining whether there are more efficient alternative routes. This method helps in identifying more minimized costs by moving a number of items from one point to another. In the context of PT. Mega Eltra, this method shows that there is a significant opportunity to reduce distribution costs, making it a better choice than other methods.

Revised Distribution Method (RDI)

On the other hand, the RDI method is a more complex approach that also aims to find optimal solutions by considering all related distribution routes and costs. Although this method gives valid results, in the case of PT. Mega Eltra, the cost produced by RDI turns out to be higher than the stepping stone. This shows that in certain situations, although the RDI method is considered more sophisticated, the results are not always better than simpler methods such as stepping stone.

Comparison of Stepping Stone and RDI Methods

Conclusion

The results of this analysis underline the importance of choosing the right method in transportation planning. Although RDI offers high accuracy, in the context of PT. Mega Eltra, the stepping stone method is proven to be more efficient and economical. Therefore, the company is advised to apply the Stepping Stone method in an effort to minimize transportation costs. In addition, the efficiency in spending distribution costs not only helps companies in increasing profitability, but can also increase competitiveness in the market.

Recommendations

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

PT. Mega Eltra should apply the Stepping Stone method in an effort to minimize transportation costs.
The company should also consider the use of other methods, such as the RDI method, in certain situations where the results are expected to be better.
The company should also consider the use of other methods, such as the Vogel's Approximation (VAM) method, to find the initial solution to transportation problems.

Limitations of the Study

This study has several limitations, including:

The study only considered the use of the Stepping Stone method and the RDI method in transportation planning.
The study only considered the use of the Vogel's Approximation (VAM) method to find the initial solution to transportation problems.
The study only considered the use of the Stepping Stone method and the RDI method in the context of PT. Mega Eltra.

Future Research Directions

Future research directions include:

The use of other methods, such as the RDI method, in transportation planning.
The use of other methods, such as the Vogel's Approximation (VAM) method, to find the initial solution to transportation problems.
The use of other methods, such as the Stepping Stone method, in the context of other companies.
