Analisis kualitas core batubara dan mine brand batubara Air Laya 72 di PT. Bukit Asam Tanjung Enim. Tujuan penelitian ini yaitu Mengetahui litologi dan seam serta spesifikasi core dan mine brand kualitas batubara di lokasi penelitian. Mengetahui Faktor-faktor apasaja yang menyebabkan terjadinya perubahan kualitas batubara dan saran pencegahannya. Melakukan analisa parameter kualitas batubara di Laboratorium. Nilai Total Moisture, Caloric, Ash, Volatile Matter, Fixed Carbon, Total Sulphur sesuai dengan Mine Brand yang telah ditetapkan untuk batubara jenis AL 72 adalah 8,57%, 7500 kkal/kg, 8,18%, 42,71%, 58,16%, 1,32% dan rata–rata 6,68%, 7200 kkal/kg, 5,17%, 35,92%, 52,22%, 0,78% dan untuk nilai core TM 5,56%, VM 34,54%, FC 56,81%, Ash 3,38%, CV 7549 kkal/kg dan TS 0,32% serta nilai mine brand yang dilakukan pengujian TM 10,93%, IM 4,31%, Ash 5,15%, VM 38,31%, FC 52,23%, TS 0,62%, CV 7301 kkal/kg. Dilihat terjadi kenaikan nilai mine brand TM 5,37% ,Ash 1,77%, VM 3,77%, TS 0,30% dan penurunan untuk nilai FC 4,58% dan CV 248 kkal/kg dibanding nilai core sehingga dapat disimpulkan nilai core lebih baik dibandingkan nilai minebrand faktor yang menyebabkan perbedaan atau perubahan kualitas dari batubara yaitu bisa dari faktor internal dan eksternal faktor internal biasanya diakibatakan oleh proses terbentuknya batubara seperti pengendapan, temperatur dan usia yang lama dapat membuat batubara menjadi lebih baik secara kualitas dan untuk faktor eksternal terpengaruh oleh Coal handling facility. Kata Kunci: AL 72, Spesifikasi kualitas batubara, Mine Brand, Core Batubara. Analysis of the quality of coal cores and coal mine brand Air Laya 72 at PT. Bukit Asam Tanjung Enim. The purpose of this study is to know the lithology and seams as well as the specifications of the core and the quality of the coal mine brand at the research site. Knowing what factors cause changes in coal quality and suggestions for prevention. Perform an analysis of coal quality parameters in the laboratory. the value of Total Moisture, Caloric, Ash, Volatile Matter, Fixed Carbon, Total Sulfur according to the Mine Brand that has been determined for coal type AL 72 is 8.57%, 7500 cal/kg, 8.18%, 42.71%, 58.16 %, 1.32% and an average of 6.68%, 7200 cal/kg, 5.17%, 35.92%, 52.22%, 0.78% and for TM core values 5.56%, VM 34,54% , FC 56.81%, Ash 3.38%, CV 7549 cal/kg and TS 0.32 as well as the value of mining brands tested TM 10.93% IM 4.31%, Ash 5.15%, VM 38.31%, FC 52.23%, TS 0.62%, CV 7301 cal/kg. Seen an increase in the value of mining brand TM 5.37% , Ash 1.77%, VM 3.77%, TS 0.30% and a decrease in value FC 4.58% and CV 248 cal/kg compared to the core value, so it can be said that the core value is better than the minebrand value. Factors that cause differences or changes in the quality of coal, namely internal factors and external factors, are usually caused by the formation process such as temperature and long life. Make coal of better quality. Factor externally affected by coal handling facilities. Keywords: AL 72, Coal quality specifications, Mine Brand, Coal Core.
