This research aims to calculate the production capability of loading and conveyance equipment used in coal mining activities, find out what factors affect non-achievement suggestions, then make efforts increase so that targets have been set can be achieved. . In this study, observation retrieval data field directly (primary data) indirectly (secondary will carried processing. Based on results calculations, it concluded Komatsu PC400LC Excavator is 18,651.11 Tons / month 4 units Nissan CWB450HD Dump Truck 18.325,66 month. Factors cause are low work efficiency due loss working time non-optimal distribution road conditions do not meet standards. Efforts load tools were made by increasing from 63.56% 64.32%, target increased 20,761.54 tons For conveyance, first alternative done 63.34% 64.10% optimize 359.77 seconds 330.10 seconds, increases 20.212,45 The second number bucket fillings 3 times times, 21.986,50
