ABSTRACT
Berau Regency is one of the regencies administration in
East Kalimantan Province blessed with several natural resources including coal
and mineral resources. Coal and mineral resources has been exctracted by mining
business activities conducted under Mining Business Permit (IUP). According to
the Law Number 4/2009, mining businesss activities shall be carried out within
Mining Area (WP). Furthermore, Mining Business Area (WUP) is a part of Mining Area
that already has data, potential and/or information about geology informations.
Geospatial analysis methode used in determining of Mining
Business Area, meanwhile Analytical Hierarchy Process (AHP) Methode used in prioritizing
Mining Business Area. Geological conditions as criterias for Mining Business Area
prioritizing, several factors were considered such as : mining commodity,
resources aspect, land status and geographical location. Based on respondens
answers analyzed by AHP methode showed that the highest weight is resources
aspect with 38.7%, then mining commodity weight is 37.4 %, land status weight
is 13.0 % and geographical location weight is 10.9%. Therefore, geological
conditions are a major factor in determining priority of Mining Business Area.
The results of spatial analysis based on geological
condition and limitation factors yield 19 (nineteen) blocks of Mining Business Work
Area consist of 5 (five) blocks Metal Mining Business Area, 8 (eight) blocks
Non Metal Mining Business Area, 2 (two) blocks Rocks Mining Business Area and 4
(four) blocks Coal Mining Business Area.
The result of weighting process of 19 (nineteen) Mining Business
Area Blocks are 3 (three) types of rank of Mining Business Area Priority such
as : Fisrt Priority Mining Business Area consist 2 (two) blocks of Metal Mining
Business Area, Second Priority of Mining Business Area consist 3 (three) blocks
of Metal Mining Business Area, 4 (four) blocks of Non Metal Mining Business Area
and 4 (four) blocks of Coal Mining Business
Area and Third Priority of Mining Business Area consist 5 (five) blocks of Non
Metal Mining Business Area and 2 (two) blocks of Rocks Mining Business Area.
The results of spatial analysis and weighting process
with AHP method showed that geological factors and spatial planning of Berau
Regency influenced of determining and prioritizing of Mining Business Area.
