Abstract

Coal handling facility (CHF) at PT. Anugerah Bara Kaltim, a mining company authorized to carry out coal crushing activities which is one of the determinant of the quantity of product to be produced to meet market need. However, problem often occur which prevent production target from being achieved. A technical study of the crushing plant unit is carried out and effort are made to minimize the obstacle that occur in coal crushing activitie. The production target for the coal crusher unit is 541,667 tons/month based on observations and calculation that have been carried out, the actual production obtained is only 519,305.85 tons/month. Production target that have not been achieved occur because the production of crushers is still low due to the obstacles that occur. From the result of research and calculations carried out to achieve production that is close to the production target of the coal crusher unit, efforts have been made to increase production, one of which is by improving non-technical barriers which can minimize the time delay. after repairing the inhibition time. The value of the availability of the coal crusher unit before repairing the drag time is as follows: mechanical availability (MA) = 95.28%, physical availability (PA) = 88.79%, equipment use availability (UA) = 95.75%, effective use (EU ) = 85.00 %. Handling that can be done by adding bait in June is 26,381.38 tons with an additional 35 times repetition in June, and in July adding bait to achieve the production target of 32,939.06 tons with an additional 44 times repetition in July with handling time delays and feed handling, the production target of the coal crusher unit at PT. ABK can be fulfilled
