Abstract
Daerah penelitian terletak di daerah Tambang Air Laya, Kecamatan Tanjung
Enim, Kabupaten Muara Enim, Propinsi Sumatera Selatan. Berada di Kabupaten
Muara Enim terletak ± 247km di sebelah barat daya kota Palembang. Daerah
penelitian ini berada pada Formasi Muara Enim yang mempunyai umur miosen
atas sampai pliosen bawah,dan pada daerah penelitian terdapat intrusi batuan beku
sedimen yang menyebabkan nilai kalori batubara lebih baik dari pada daerah yang
tidak terdapat intrusi batuan beku. Penelitian ini menggunakan metode well
logging dengan titik bor sebanyak 3 titik bor. Tujuan penelitian ini adalah untuk
analisa dari hubungan data log densitas dengan nilai kalori air dried basis dan air
recived lapisan batubara daerah Tambang Air Laya, Kecamatan Tanjung Enim,
Kabupaten Muara Enim, Provinsi Sumatera Selatan. Hasil penelitian
menunjukkan bahwa batubara pada daerah penelitian memiliki rata – rata nilai
densitas 1.5 sampai 2.00 gr/cc, kalori ADB 6845.96 cal/gr dan kalori AR
6239.03cal/gr . Dengan menggunakan metode trideline scatterplot bivariant
digunakan untuk mendapatkan hubungan korelasi dari 2 variabel, dimana pada
daerah penelitian memiliki hubungan lemah sampai sedanng. Dari hasil hubungan
antara Hubungan antara density air dried basis dengan kalori memiliki variasi
positif R2 = 0.5305 = 53.05% dan hubungan antara density air recived memiliki
variasi positif R2 = 0,5507 =55.07 %.

The study area is located in the area of Mine Air Laya, District Tanjung Enim, Muara
Enim, South Sumatra Province. Being located in the district of Muara Enim ± 247km
south-west of the city of Palembang. The study area is located in the Muara Enim
Formation which has upper Miocene to Pliocene age the bottom, and in the research
area are igneous intrusions of sediment that causes the calorific value of coal is better
than the regions that are not igneous intrusions. This study uses a method well logging
with drill point drill as many as 3 points. The purpose of this study was to analysis of log
data density relationship with a calorific value of water and air dried basis recived coal
seam mining area Air Laya, District Tanjung Enim, Muara Enim, South Sumatra
Province. The results showed that the coal in the research area has average density value
of 1.5 to 2:00 gr / cc, calories ADB 6845.96 cal / g and calories AR 6239.03cal / g. By
using the scatterplot trideline bivariant used to obtain the correlation of two variables,
whereas in the study area has a weak relationship to moderate correlation. From the
results of the relationship between the relationship between the density of water dried
with a calorie basis has a positive variation of R2= 0.5303 = 53.03%, and the
relationship between the density of water recived have a positive variation of R2 =0.5507
= 55.07%
Keywords: intrusion, well logging, log density, air dried base, air recived
