Supplier Selection Analysis for Sand Materials Using AHP in the Indonesian Manufacturing Industry

The analysis of supplier selection aims to identify suppliers that best match an organization's specific needs.In the past, an Indonesian manufacturing enterprise relied solely on price as a criterion for selecting suppliers, overlooking other important factors.This study employs a qualitative approach using the analytic hierarchy process (AHP) to select suppliers of sand raw materials.A geometric mean algorithm calculates eigenvalues and ranks the suppliers based on various criteria.The evaluation is based on the vendor performance indicator (VPI) criteria, which include quality, cost, lead time, flexibility, and responsiveness.The findings indicate the following global weightings for each supplier: Supplier U (0.224), Supplier V (0.327), Supplier W (0.197), Supplier X (0.123), Supplier Y (0.052), and Supplier Z (0.077).From this assessment, Supplier V is identified as the most suitable vendor for raw sand materials.Consequently, the enterprise should consider selecting Supplier V as its primary supplier.
