【 摘 要 】

This study aims to know the total profit gained as the third party's saving effort as waste processor from the utilization of foundry sand paper sludge as the raw material of red brick without burning. There are variations of the composition of the raw materials to get the red brick product with the quality of 50, that is A, B, and F. the calculations are obtained from the red brick production calculation data from 5% subtraction of the amount of paper sludge and foundry sand needed to meet production needs, production cost calculation data from consumables material which is being used in the making process of red brick without burning, calculation of waste fees data by the third party, third's party economic benefits and total profits calculation data as effort of saving by the third party. So, the total profit obtained by producing A variation is IDR841.803.600,00; B IDR471.602.500,00; and for F is IDRp556.641.900,00.
