Abstract
Mining activities conducted in PTBA is directed to undertake the mining environmentally.
Mining activities conducted include exploration, land clearing, stripping topsoil, excavation of
overburden ,coal mining, transporting, processing and marketing of coal. Reclamation is the
activities that are performed throughout the stages of the mining effort to organize, restore, and
improve the quality of the environment and the ecosystem to function returns appropriate
allocation. The success of reclamation activities according to Regulations the Minister of
Mineral Resources number 07 2014 covering the activities of the arrangement of land, the
promised land of tops (top soil), water management and erosion control, revegetation and the
prevention and mitigation of acid mine water. All activities on the reclamation process above
requires considerable cost and its implementation should be planned so that the cost have to be
effective and efficient.
Technical planning of reclamation on the outside dump Mahayung 2015 designed by
rearranging the land by using the method of encapsulation, perform the promised land of tops to
immediately do revegetasi, make and take care of the channel that is in a outside dump of
Mahayung to prevent erosion and maintain the water and add to the compartment on a pool of
Mud and Precipitator liming regularly to prevent the occurrence of acid mine water. The cost for
the reclamation activities at the outside dump of Mahayung is the total cost of reclamation
consists of two that is direct costs and indirect costs. Direct costs for reclaiming the year 2015
amount Rp 39.565.434.558,- and indirect costs Rp 3.758.716.283,- Then the total cost of
reclaiming the year 2015 amount to Rp 43.324.150.841
