The results showed that there were 4 criteria and 12 sub-criteria, where the Quality criterion (K2) had the greatest value (0.6237), the Accuracy in the Number of Delivery sub-criteria (D1) had the greatest value (0.7215), and based on the calculation of the AHP method which became the priority the first is the IHI supplier (0.4144). Based on the calculation of the TOPSIS method, the first priority is IHI suppliers with a preference value (0.7922). The results of this study show that IHI suppliers are a top priority and are able to meet all the raw material needs for Viton O-ring parts at PT XYZ.]]>
