Abstract

Abstract. Based on data from bauxite production in April 2019 at PT. Bhakti Karya Mandiri, bauxiteproduction did not reach the target. the production target is 25000 bcm. but the production achieved wasonly 16,916 bcm. This is caused by wasted work time and disruption time which causes operating timeand productivity to be low. To determine the potential for improving the production process and theeffectiveness of using equipment, an analysis using the overall shipping effectiveness (OEE) methodneeds to be done. After analysis and improvement methods were carried out, the production of KobelcoSK 330 exceeded the planned target which was previously 16,916 bcm to 25,629 m³. But the OEE valueis still <61% not yet achieved the world class OEE> 85%, it can be concluded that the use of equipmentis not optimal.

Abstract

Abstract. PT. Semen Padang is located in Indarung Village, Lubuk Kilangan Subdistrict which is 14 KM from the center of Padang City with a height of + 200 m above sea level is one of the companies engaged in the cement industry. Reserve calculation is an important work, the responsibility is in evaluating a mining project. All technical decisions are very dependent on the work. In this study, calcareous reserves will be calculated based on the cut-off grade of each material. In each of these materials there are levels of SiO2, Al2O3, CaO and MgO. In calculating the limestone reserves contained in the Tajarang Hill area, this was done using geostatistical techniques. This geostatistics uses the estimation method while still based on the model. The method that will be used in geostatistics is the indicator krigging method. The IK estimation method does not use the assumption of a normal (free) distribution, and still takes into account the outlier (high levels), so that it can be applied to the estimation of limestone reserves. The IK method is based on the concept of probability. Data is converted into indicators with zero (0) and one (1) value relative to a limit level (discriminator). The purpose of the IK assessment is to estimate the probability at various levels of a predetermined limit. From the results of calculation of limestone resources using the krigging indicator method based on the cut-off grade of PT. Semen Padang obtained the amount of limestone resources of 36,764,700 m 3 or 97,426,455 tonsKeywords: Reserve calculation, cut off grade, geostatistics, indicator krigging, and probabilistic

Abstract

Abstract.The people’s limestone mining in Bukit Tui has a mineable reserve of 12,826,641.60 MT. This study analyzes the limestone processing techniques in the Bukit Tui people's limestone mining and also analyzes the economic feasibility of the processing using the Discounted Cash Flow method. The efficiency of the limestone furnace at the Bukit Tui processing plant is very low, at 26.63% for each ton of lime produced with fuel consumption of 336.18 kg/ton of lime which generated. This is due to the incomplete combustion process. To increase the combustion efficiency, a furnace modification is needed, in the form of adding fans and recuperators. In the case of Bukit Tui limestone processing, the air needed is 8,928.42 kg. Therefore to complete the combustion process, a fan is needed to supply air to the furnace with a discharge of 0.07 m3/s. And if combustion takes place completely, fuel consumption will be reduced to 89.49 kg / ton of lime produced. Based on an analysis of economic value, it can be seen that the economic value of the Bukit Tui limestone processing can be declared economically feasible. However, it still needs to be adjusted to the processing technique to match the good mining practice rules (GMP).Keywords: Limestone, GMP, Processing Techniques, Furnace Efficiency, Economic Value
