L Limestone mining activities of PT. Holcim Indonesia pit kamuning tunnelsand extensions using 2 types of gear loader tool that is Cat 1k Cat loader wheel loader1 unit and Cat990H Wheel Loader amounted to 2 units, and 2 types of transportequipment that is DT Cat777D amounted to 6 units and DT Cat773E amounted 6units. The working system is a Cat992K 1 Wheel Loader with 3 DT Cat777D and 1Wheel Loader Cat990H with 3 DT Cat773E. With this work partner the monthlyproduction target of 650,000 tons / month is not achieved. It is therefore necessary toevaluate the loading and carrying tools.The purpose of this research is to perform a combination of working pairs ofloading and hauling equipment to achieve a specified production target. The researchmethod used is action research and using quantitative data with megukur time offreight and conveyance equipment, bucket fill factor. The actual productivity of WLCat992K and DT Cat777D is 959 tons / hour and 330.7 tons / hour. Productivity WLCat990H and DT Cat773E is 820 tons / hour and 219 tons / hour, And totalproduction yielded 581,781 tons / month. When a work partner is exchanged theproductivity of the tool changes. WL Cat992K and DT Cat773E obtainedproductivity of 228,4 tons / hour. Productivity WL Cat990H with DT Cat777D to327.4 tons / hour, with total production of 588,857 tons / monthby simulating swapping pairs of work, there is a change in the productivityof the conveyance due to changes in the time of its release when changing partners.When the Cat992K WL is paired with DT Cat777D and WL Cat990H with theremaining 3 DT Cat 777D units. the production produced is 661,046 tons / monthindicating that the production target can be achieved.
