Abstract


PT.Artamulia Tatapratama is a company engaged in the field of coal mining. PT.
Artamulia Tatapratama is located at Tanjung Belit Village, Jujuhan District, Muaro Bungo
Regency.
In the overburden hauling process to the disposal area there is a dumptruk queue at
some point of the road and long stand by time on the loader, this can cause the loader and
hauler productivity to be small so that the production target of 1.190.838 bcm / month
overburden is not reached. This incompetence is due to a combination of unsuitable tools
causing the occurrence of a waiting gateway or a queue of loads when it is loaded by a
loading device. One way to achieve the production targets is required appropriate fleet
management.
Based on the theory of queue, the waiting time for the conveyance at the time will be
loaded is 13.62 minutes on fleet 1, 22.88 minutes on fleet 2 and 14.58 minutes on fleet 3.
Fleet setting based on the queue theory is 1 unit PC 1250 serving 6 units of HD 465 on fleet
1, 1 unit PC 1250 serving 4 units of HD 465 on fleet 2, 1 unit PC 1250 serving 5 units of HD
465 on fleet 3.
