There are four productions of granite processing, namely stone ash, screening, stone 1/2 and 2/3, seen from the modulus of fineness by means of a sieve analysis test, rock ash with a fineness modulus of 2.45, stone 1/1 or screening has a modulus smoothness 6.32, stone 1/2 with modulus to smoothness 6.42 and stone 2/3 having a modulus of fineness 6.29. There are two types of costs incurred to produce these products, namely owning costs with a total cost of IDR 231,904,748 / month and an operating cost with a total cost of IDR 369,359,470.80 / month.
