Abstract

Feed gas which is produced by the factory of gas processing generally contains acid gas with high concentrations of acid gas wich must be removed by reducing the contrentration of CO2 and H2S according to product specification of sweet gas of <4 ppm-mol H2S and 5 % CO2. The research on the unit of WSA aimed to compare the simulated data and actual performance data and trial simulation (combustion pressure, the inlet temperature of SO2 converter, and water excess. The method used to retrieve the actual data of each piece of equipment was the results of the analysis of the composition of the acid gas, the composition of the stack, and purity H2SO4. The results obtained showed that the conditions of the performance test and simulation are not significantly difference, yet the purity H2SO4 obtained from the simulation results higher than the performance test. Based on the results of observations showed that the higher the molar flow acid gas is the higher the flow rate of the inlet will be and influence to the products where the flow rate of H2SO4 will decline, when water excess is added, the purity of the product will increase, and the flow rate of product will decline. There are differences in the purity of H2SO4 from the performance test and simulation.

Abstract

I In nickel laterite mining, it is necessary to map grade distribution and estimates to be able to calculate resources before the mining process takes place. Resource estimation plays an important role in determining the quantity and quality of a deposit. On the basis of the foregoing, a study was conducted on exploration activities aimed at determining the amount of nickel laterite deposit resources. In this study, estimation of nickel laterite resources was carried out using the Inverse Distance Weighting (IDW) method. The purpose of this study was to determine the direction of distribution of grades and amount of nickel laterite deposit resources in the study area. This research was conducted using Microsoft Excel software, ArcGIS 10.8, surpac 6.5.1. Based on the results of the drilling database provided by PT X which totaled 20 drill points, the distribution of nickel laterite mineralization grades in the study area based on grade distribution maps, laterite nickel with grades <1 occupies the western and southeastern parts of the study area (green, yellow and red). , while the distribution of laterite nickel grades with grade values > 1 occupies the northeast, southwest and northwest (dark gray and purple colors). has nickel resources of 169.950 tons, with an average value of Ni content of 1,87% from the number of drill points of 20 with a spacing of 50 m.

Abstract

Mining Design plays an important role in extracting reserves from mineral deposits. The mine design makes it easy to meet production targets and is ideal for horizontally shaped ore bodies such as coal. The purpose of this study is to determine the design of the ramp in the mining pit, determine the ramp pit and the type of ramp used. This research method uses mine planning surpac software and data processing excel software to make a ramp design, determine the type of ramp. The results of the research that has been carried out obtained a ramp design with the type of Constant berm ramp using a stepped geometry, namely the maximum overall slope of the high wall is 60° and the low wall is 45°, the step height is 8 m, and the step width is 3 m, the road width is 10 m, with a road grade of 12%. of these results assumes that the mine is theoretically free from landslides. So that the tool can work optimally both empty and loaded on an incline. The type of road used has the highest level of safety when compared to other types of mining roads.

Abstract

Electrical energy is one of the basic needs in modern human life. Electricity is very integrated into everyday life, work, or commercial. Indonesian society, urban, already depend on electric energy to run everyday life. The purpose of this study to determine the level of electricity consumption in South Sulawesi and to determine selling value of energy demand to PLN. Stages and research methods undertaken consist of the process stages of research, methods of data retrieval, data processing and stages of data analysis, and the stage of report generation. The data taken are primary data and secondary data, after the data collected data are analyzed to calculate the supply-demand of electrical energy needed by PLN. The composition of electricity demand in the base year (2013) consists of Commercial sector 999,485.90 MWH, industrial sector 859,482.75 MWH, government sector 248,237.97 MWH, social sector 202,789.65 MWH and household sector with 2,568,038,85 MWH. For the year 2015 also still dominated by the household sector with 2,568,038.85 MWH. This figure is the same from 2013. Likewise with the commercial sector which rose to 1,011,709.57 MWH and industrial sector to 861,117.44 MWH. government sector to 249,256.10 MWH and social sector to 204,689.38 MWH. To be able to meet the needs of electrical energy in South Sulawesi, is expected with the power plant PLTU PT. Bosowa Jeneponto Energy with total power generated of 128,877.37 MWH can supply electrical energy for PLN South and West Sulawesi in fulfilling the needs of 100 MW electricity energy every year for new customers, with the selling price of PLTU power plant PT. Bosowa Energy to PLN Rp 500 / Kwh.

Abstract

Batugamping disebut juga batukapur atau limestone merupakan batuan sedimen dengan kandungan mineral kalsium karbonat (kalsit) CaCO3 sebesar 90%, dolomit 3% dan sisanya adalah mineral clay. Penelitian ini bertujuan untuk mengetahui karakteristik mineral batugamping berdasarkan analisis petrografi dan mengetahui komposisi mineral batugamping berdasarkan analisis XRD serta mengetahui lingkungan pengendapan mineral batugamping. Metodologi penelitian didasari dengan melakukan pengujian berupa analisis XRD dengan menembakkan sinar X pada sampel untuk mengetahui komposisi mineral dan analisis petrografi menggunakan alat mikroskop menyinari berkas cahaya atau elektron pada sampel batuan pada suatu jalur optik untuk mengetahui mineral penyusun pada batuan. Berdasarkan analisis petrografi, pada sampel 1 menunjukan mineral kalsit, grain, opak, dan mud. dengan nama batuan packstone. pada sampel 2 menunjukan mineral kalsit, grain, opak, mud. dengan nama batuan wackstone. pada sampel 3 menunjukan mineral kalsit, grain, opak, mud. dengan nama batuan wackstone. pada sampel 4 yang menunjukan mineral kalsit, grain, mud. dengan nama batuan tersebut packstone. Komposisi mineral berdasarkan analisis XRD pada sampel 1 menunjukkan kandungan kalsit (CaCO3) sebesar 100%. Hasil analisis XRD pada sampel 2 menunjukkan kandungan kalsit (CaCO3) sebesar 100%.
