The development activities of the former coal mine will face problems in the form of mining mud material. Mud is a liquid or half liquid material formed from a mixture of water and soil. Special techniques are needed so that production targets are achieved. PT Arutmin Indonesia Senakin Mine found a problem related to the mining of mud material in pit 8 mining. Mud must be cleaned up immediately so that coal mining can be carried out. In the mud removal activity at pit 8, Senakin Mine operates the Hitachi 1200 excavator as a digging device and the CAT 777D dumptruck as a conveyance. From the observations obtained a match factor value of 0.47 and 0.54. Even though the match factor values are 0.47 and 0.54, the mud production target has been reached. Therefore there is no need to add transportation units because the production target has been reached. The productivity value of Hitachi 1200 excavators is 140 BCM / Hour and 129 BCM / Hour. While the productivity value of the CAT 777D dumptruck is 40 BCM / Hour and 45 BCM / Hour for one dumptruck unit. The production target set is 3500 BCM within 2 days.
