The imbalance between coal demand and supply realization during 2023–2025 highlights the importance of selecting appropriate suppliers to support coal supply fulfillment at PLTU in Java Island. This study aims to determine the criteria and subcriteria for coal supplier selection, calculate their weights using the Analytical Hierarchy Process (AHP) method, and rank suppliers using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The novelty of this study lies in the development of supplier selection subcriteria based on expert judgment and adjusted to the operational conditions of PLTU in Java Island, resulting in different criteria priorities and supplier rankings compared to previous studies. The results show that quality is the most important criterion with a weight of (0,301), while calorific value is the main subcriterion with a global weight of (0,198). Supplier AI achieved the highest preference value (0,942), followed by BT and BA (0,911), making them the recommended main suppliers. Meanwhile, MI and ABP obtained the lowest preference values (0,246), indicating the need for further evaluation and reconsideration of future cooperation.
