Abstract
White cement is the cement that consumers use to make exterior and interior decorations of homes and buildings without reducing the quality of the compressive strength of the cement so that it can increase the selling value and beauty of the building. The company “X” is the only white cement producer in Indonesia, strives continuously to improve its quality in terms of its production process to produce products that are acceptable in the market. This study aims to create a standard series of testing the value of the degree of whiteness and see the difference and the relationship of each tool. The method for making the standard series is by using two types of cement, white cement with a ratio of 100% by weight of 600g used up to 10% by weight of 600g of white cement used and gray cement Ordinary Portland Cement (OPC) with a ratio of 100 % by weight of 600g used up to 10% by weight of 600g of gray cement. This test showed that the degree of whiteness decreased in the three tools, this is proportional to the use of the higher percentage of Ordinary Portland Cement (OPC) gray cement. The results of the comparison of the three tools obtained a linear regression value (r) which is close to 1 so that it can be said that the three tools have an interrelated relationship so that the value generated from one tool can be equated with other tools.
