Modeling of Land Clearing and Reclamation for Mining Area of Nickel

Land clearing and reclamation in the mining process impact the environmental sustainability. Therefore, understanding the dynamics of land clearing and reclamation is very important. In applying the model to planning land clearing and reclamation of mining areas, there is a threshold for the area to be explored and reclaimed. The simulation process was carried out using data from PT. Manusela Prima Mining regarding the land clearing and reclamation plan for Nickel land in Maluku for 2022-2029. As a result, the logistic equation is suitable for land clearing and exploration planning. We analyze positivity and boundedness of the system. In addition, the study analyzed environmentally realistic equilibrium states by applying the eigenvalues criterion, which is mathematically proven to be locally asymptotically stable. The equilibrium region shows stability for various parameters, including scenarios with no action taken for reclamation and scenarios where two actions coexist in a sustainable manner. Numerical simulations reveal that fighting power significantly converts exploration efforts. This conversion leads to reclamation growth. Our research uses a modified logistic model. It also explores thresholds for environmental sustainability.
