Abstract

Stockpile is a temporary storage place for coal before it is sold to consumers. The stockpile must be properly regulated so that the quality of the coal is maintained, so that when it reaches the consumer it is still of the desired quality. The plan is that in November the coal that will be included in the ROM stockpile of PT. Bara Mega Quantum will experience changes, both in quality and quantity. This study aims to determine the readiness of the stockpile to face the planned increase in coal production. PT. Bara Mega Quantum has a ROM Stockpile which is located southwest of the mining site, precisely located in the coal processing area on Pulau Baai Terminal Coal PT. Pelindo Bengkulu, Kampung Melayu District, Bengkulu City, Bengkulu Province. Where the distance between the pit and ROM Stockpile is approximately 67 km. The processing area consists of ROM Stockpile, Hopper, and Jetty Loading. Based on calculations from rainfall data, the total water discharge entering the ROM Stockpile area is 4393,67 m3/day. To accommodate this amount water, sufficient dimensions of the settling pond are needed to prevent overflow. Based on the data processing carried out, the dimensions available sludge settling pond are 5960 m3. The height of the coal pile is taken based on the specifications of the Whell Loader with the Komatsu 350 type. The following is a picture of the dimensions of the Whell Loader with the Komatsu 350 type used in the ROM Stockpile activity by PT BMQ. In accordance with the design that has been made and the data that has been processed for the capacity of the coal stockpile on the ROM Stockpile, namely on ROM 1, ROM 2 and ROM 3, the volume obtained is 20214.58 m3 and for tonnage 26278,95 MT.

Abstract

Analysis of financial statements is an important step in assessing the value of the company. This research has a goal of determining mining costs based on the stripping ratio and the amount of profit obtained from the mining plan. In this study, the author uses an applied method with a quantitative analysis approach, where research demands the use of numbers, starting from data collection, interpretation of the data, and the appearance of the results which are presented in the form of mathematical calculation results. Coal production produced in 2021 is 305,100 MT/Year and Overburden production is 1,054,815 BCM/Year, so the coal production cost is Rp. 103,900.11/MT or $ 7.27/MT and an overburden fee of Rp. 41,176.94/BCM or $2.88/BCM. Based on the Reference Coal Price in 2021, after calculating the sales of domestic and export coal, the sales income of $26,532,614.30 for a year (2021) was obtained.
