Because it has a system that is not right, the company gets suppliers that have not met the requirements. The goods shipped are of poor quality.

In this method, the first step is weighted for criteria using the Entropy method. There are 4 criteria selected in weighting, price, weight, durability, and design attractiveness. Then, select the supplier with the TOPSIS method. There are 3 suppliers that will be analyzed based on predetermined criteria. After doing the analysis, get the results of 1 supplier, namely PT.
