SISTEM PENDUKUNG KEPUTUSAN DENGAN MENGGUNAKAN METODE WEIGHTED PRODUCT (WP) GUNA MENENTUKAN MATERIAL KAIN TERBAIK UNTUK PRODUKSI FOAM MATTRESS PADA PT. XYZ

PT. XYZ is one of the manufacturing companies that has a background in foam mattress production. Quality raw materials are a company asset that plays an important role in supporting production activities. PT. XYZ in the process of selecting good fabric materials is still based on subjective analysis of Quality Control (QC) officers in the field, sometimes the data owned as a reference for standardization can still change according to the demands of field conditions. Furthermore, a study was conducted on determining the best fabric material for foam mattress production at PT. XYZ using the Weighted Product Method. This study was conducted for 3 months with the stages of system creation including system design, system testing, system improvement, and training. The results of the study showed that the system created using the web-based PHP programming language makes it easier for users to access, save time, and minimize human error in data processing. Finally, from the results of the questionnaire data processing, a significance value of 0.000 <0.05 was obtained with an average difference of -3,800 which means that the decision to select fabric at PT.
