【 摘 要 】

Geology of North Morowali Regency is dominated by ultrabasic rock compounds, most of which have weathered to form rich nickel. The Local Government has issued 52 letters of Nickel Mining Business Licence with a total area of 177,249.20 Ha. Issues for local government are: there are indications of overlapping of land Licences, areas for other limited uses, and many abandoned mine land. Local governments should have clear rules in the provision of Mining Business Licence in order not to cause spatial conflicts. Decisions must be supported by a system that can help local governments to minimize the occurrence of problems. The purpose of this research is to select mine land allocation by using MOLA (Multi Objective Land Allocation) Model. The method used is multicriteria analysis by weighting and scoring in Geographic Information System. The model results show scenario 2 with the proposed 80,000 ha mine area is the best choice, and recommended to the local government. The allocation of mining area is 69, 72%, so there is still 30, 28% for other used. In this scenario, mining area with Exploration Mining Business Licence status decreased 49.60%, while with Production Operation Mining Business Licence status decreased 24.41%.
