ABSTRACT
West banko Pit 3 coal mining project is owned by PT. Bukit Asam (Persero)
Tbk., was working by PT. Bangun Karya Pratama Lestari Contractors. The project
is located in Lingga village, district Lawang Kidul, Muara Enim regency, South of
Sumatera province. At west Banko pit 3 during year 2014 there are no able to plan
production target by owner.
Based on data in field, accomplishment production target overburden and coal
only amount 84% from plan. Production target plan during year 2014 is 4.490.000
bcm overburden and 1.600.000 ton coal with total cost of production amount
Rp.157.602.542. Meanwhile actually production target in year 2014 only amount
3.796.943 bcm of overburden and 1.389.548 ton of coal, with total cost of
production amount Rp. 149.889.534.648. Production cost of overburden and coal
gives effect by production achieve. The plan production cost of overburden and
coal is amount Rp.35.101/bcm and Rp. 98.502/ton coal, while actually production
cost is amount Rp. 39.476/bcm overburden and 107.869/ton coal.
Because was found lower job efficiency until happened taking down of
productivities equipment. Job efficiency most effect by barriers was happened
during mining activity. Which means should do it for increase job efficiency is
substract the increase during mining take place. After that, then job efficiency and
productivities advanced and get the plan production target. After that do
improvement, so production cost become Rp. 154.326.192.958 with production
cost of overburden Rp. 37.808/bcm and Rp. 106.099/ton of coal.
