Abstract

Choosing a supplier is a strategic activity, especially if the supplier will supply items that are used for a long period. PT. CPS is a company engaged in the construction services sector which also carries out procurement process activities, including the supplier selection process. In carrying out the building production process, PT. CPS requires the main raw material, namely light brick (Autoclaved Aerated Concrete). PT. CPS does not yet have a main supplier of light bricks AAC, and supplier selection is done subjectively and based on the lowest price without making certain calculations. This resulted in several problems such as miss communication during the process of ordering materials, and delays in delivery that made the company have to order from other suppliers. This study aims to calculate the criteria weight for light brick suppliers and select the best light brick supplier based on the weight criteria specified by PT. CPS. The process of making supplier evaluation criteria is carried out using the Analytical Hierarchy Process (AHP) method and ranking suppliers with the Technique Method for Order Preference by Similarity to Ideal Solution (TOPSIS). From the research results obtained weighting of 5 criteria, namely the criteria of price, quality, delivery, reputation and position in industry, and communication system by placing the price criterion as the criterion with the greatest weight, which was 0.56165. The supplier ranking results obtained the best light brick supplier in the first position, namely PT. Sinar Indogreen Kencana with a Preference Value of 0.76858, the second position of PT. Superior Prima Sukses with a Preference Value of 0.49827, and the third position is PT. Viccon Modern Industry with a Preference Value of 0.49448.
