This research was conducted at a water treatment company with coagulant chemicals as the main raw material. So far, the company has only used one supplier to procure coagulants, but the company has received offers from several suppliers. This is of course a problem of how to choose the best supplier in accordance with the criteria set by the company. The AHP method is used to solve the problem of coagulant supplier selection. Supplier selection is one of the most important things in purchasing activities for companies, where purchasing activities are activities that have important value for companies because purchasing components, raw materials, and supplies represents a fairly large portion of the finished product. There are many offers by suppliers, selected 3 suppliers (A, B, C) that are worthy of consideration with the 6 criterias. The results of this study are supplier A in the first rank (weight 0.67), Supplier B in rank 2 (weight 0.19) and supplier C in rank 3 (weight 0.15).
