ABSTRACT
PT. Bintang Mitra Sejahtera (PT. BIMA) is one of the limestone mining
companies located in Ajibarang District, Banyumas Regency, Central Java. Where
this company is a contractor company PT. Sinar Tambang Arthalestari (Semen
Bima). In carrying out limestone mining activities, PT. Bintang Mitra Sejahtera
(PT. BIMA) uses a Surface Mining system. Within a day, cement needs by PT. Sinar
Tambang Arthalestari (PT. STAR) is 3,400 tons / day to meet the needs of Limestone
as a raw material for making cement. Limestone mining is currently done using
Hitachi 470 LC Backhoe and Backhoe Doosan DX 340 as loading-digging tool, and
dumptruck Hino FM 260 IT as a conveyance.
At this time PT. Bintang Mitra Sejahtera has a target of limestone production
supply of 3,400 tons / day when it is taken into consideration when this production
target has not been achieved. The current actual production of loading and
unloading equipment is 3.174 tons / day and for transportation equipment is 2.867
tons / day. The production target is currently not approved because of the low
effective working time of the challenges that exist in increasing work efficiency to be
low.
Efforts can be made so that the production target of stone supply can be
increased by increasing working time so as to increase work time, improve tool
circulation time. After repairs to effective working time, circulation time to obtain
production capability of 3.768 tons / day on digging-loading equipment, and 3.536
tons / day on transport equipment.
