Abstract

Coal oil mixture (COM) is one of the methods of making liquid coal fuel in addition to liquefaction and coal water fuel. Coal oil mixture (COM) is a mixed fuel with a balanced composition between coal, petroleum, and additives (Maeda, 1991: 66).In this study, the coal used is low rank coal mixed with additives and diesel. The ratio of coal: diesel: the additives used are 25%: 75%: 0% (COM A1), 25%: 74%: 1%, (COM A2) and 25%: 73%: 2% (COM A3).The results showed that the viscosity characteristics tested on COM A1, A2, A3 were closer to MDO than HFO as standard ISO 8217 2010 MDO (Marine Diesel Oil) viscosity with maximum limit of 11 cSt at 400c temperature. The calorific value of COM A1, A2, A3 is lower than MDO due to the utilization of low calorie coal in the mixture.

Abstract

Abstract. Based on the coal price index issued by the global coal new castle index, coal prices experienced an increase in mid-2016, as of 2017 coal prices reached $80-100 per ton. To obtain profits, companies need to increase production targets by re-planning mining designs. Before changing the mining design, the total production target for overburden stripping was 87,077,536 bcm and coal production was 6,022.83.3. After a change in mining design, the production target increased, the total overburden production target was 212,815.00 bcm and the coal production target was 13,390.00 tons. In the re-planning of the mining design, it is necessary to assess economic feasibility by considering the need for excavators and transport equipment, production targets, and costs to be incurred during mining.In carrying out this research, the author combines theory with field data, so that both approaches are obtained from problem solving. The research method used in this th esis is a quantitative research method. This research is more directed to descriptive research, which is one type of research that aims to solve problems by collecting data, compiling, analyzing and interpreting it. Based on production targets and results of productivity studies, overburden stripping uses 8 units of Caterpillar 390D excavators and 36 units of Caterpillar 773E OHT. Coal mining uses 1 units of Hitachi ZX 470 excavators and      6 hino FM 260Ti dumptruck units. The total costs incurred during mining amounted to $966,405,923.28 and the total profits obtained were $81,178,110.72. The feasibility of the investment plan after the change in mining design obtained a positive NPV, IRR value of 43% and a payback period of 3,49 years. Keywords: Production Target, Equipment Needs, Costs, Benefits, NPV, IRR, Payback Period
