Reklamasi Tambang Dengan Menggunakan Metode Simplek

Abstract

The mining industry has positive and negative impacts on the environment, so maximum utilization is carried out in reclamation activities. In maximizing company profits with limited resources, this problem can be solved by using linear programming models, including the simplex model. Therefore, an analysis was carried out to determine the maximum benefits of reclamation in terms of land and appropriate plant types. The research was conducted using the simplex method to determine the decision variables in reclaiming mining areas, so as to obtain maximum benefits. Based on the calculation results using the simplex method on the reclamation of mining areas with jabo, aren and dao plants amounting to Rp. 107,810,000,- from planting jebon (X₁) = 0 Ha, aren (X₂) = 2.68 Ha and dao (X₃) = 68.3 Ha. Planning and implementing reclamation to restore the environment can be done using linear programming to determine the number of plants to be planted on the land to be reclamation.
