Porosity and Density Analysis Using Regression Tests and Analysis of Elasticity Modules
A polynomial regression test was performed to find out the relationship of density to porosity. With a regression test, the correlation between density and porosity can be known to looking for the right order. The right order to use is order 3 which has the value of y= -0,0002x3 + 0,0102x2 - 0,1104x + 3,3713 with a value of R2 = 0.78. Based on the porosity, density, and scale values it can be concluded that in this area there are types of limestone. Besides, the Modulus of Elasticity calculation has been carried out to determine the distribution of rock types found in the Karst area of Batu Maros Forest. The average rock found in the Maros Forest area is limestone as evidenced by the compatibility of the Modulus of Elasticity in the table of rock types and the modulus of elasticity that is equal to 14.78779916, 16.27819781 and 20.79792362 and the rest is a gypsum stone type so that the prospect can be used as raw material for making cement.
