The teaching factory (TEFA) in State Polytechnic of Malang (Polinema) attempts to address the replication of the real industrial process inside the traditional educational setting. In Polinema, the TEFA deals with the bottled mineral drinking water, and its supply chain starts from the water purifying until the marketing. A key aspect of achieving an economically and technically feasible production is the selection of wellspring as the source of raw material. The potential water sources are located at Wringinsongo, Ampeldento, Prigen, and Ngijo in Malang area. A decision support system is required to select the suitable source by integrating weighted tangible and intangible criteria, namely water quality, distance, and willingness to pay. Multicriteria decision-making by analytical hierarchy process is applied to assign criteria weight and select the source. The results demonstrate that Ngijo wellspring is recommended, followed by Wringinsongo, Ampeldento, and Prigen according to the performance value. The system could serve as a tool for the selection, instead of intuitive judgment with a better compromise for improving the TEFA productivity. © Published under licence by IOP Publishing Ltd.
