Abstract

Material waste is one of the serious problems in making ready mix concrete. Efforts to reduce the material waste will help companies increase profits and reduce material costs as well as production processes effectivity that have an impact on the products quality. This is a case study in PT Waskita Beton Precast, the purpose of this study was to determine the causal factors and how to reduce those in order to reduce material residuals. The method used is Analytic Hierarchy Process (AHP) with respondents that related to the ready-mix concrete production. From the pairwise comparison and weighting rank results show that strategy that should be chosen is developing quality of work process (0,499) which involves production function (1,711). Therefore, production function which covers throughout production control has the most priority to develop so that material cost will diminish as the cutting material cost (1,430) is one of best plans. Significant factor such as proper material handling will enhance its strategy performance since it has the highest rank (0,330) and correlates with proper material usage-storage-movement.
