Soil quality is a frequent problem hindering mine reclamation success. Much research conducted on this problem proposed the application of organic material for soil amendment. However, most of the soil amendment research only focused on the usability of organic material, such as providing nutrients, improving soil properties, and adsorbing hazardous elements. Considering that reclamation is a complex activity, we propose a comprehensive assessment of both technical and managerial aspects on the selection of organic material due to the distinctive properties of each organic material. This study aimed to assess the criteria that influence the organic material selection and determine the most suitable alternative of organic material in mine reclamation. The assessment was Analytic Hierarchy Process (AHP) with the expert choice concept. The criteria used in this study were availability, cost, usability, ease of application, and side effects. Oil palm empty fruit bunch (EFB) compost, rice husk charcoal, cattle manure, and guano were selected. This study showed that availability was the principal factor, followed by usability, cost, ease of application, and side effects. The analysis also showed that the most suitable organic material was oil palm EFB compost with a global priority of 0.363, followed by rice husk charcoal (0.244), cattle manure (0.218), and guano (0.175).
