Abstract
Abstract. Tanjung Formation is an Eocene - Oligocene coal carricr formation. This formation igraphically situated above the bedrock of Pratersier age. The location of步 is in Binuang area, South Kalimantan approximately 20 km northwest of Banjarbaru city. The method of research by taking the coal sampling from the bottom seam to the top. Laboratory ysis is done in the form of coal petrography analysis and adsorption test. Coal Tanjung Formation is found with thickness 50 to 600 cm. Mcgascopy, this coal seam is black. bright (bright-bright banded), black scratch, concoidal shards, and lightweight. Results of developing meceral analysis were vitrinite 22. 6% - 46.4%, inertinite 0.6% - 19.4%. and liptinite 0.4%o, mineral matter 0.4% - 0.6%. Based on the reflectance reflection of vitrine (Rv) shows the range between 0.53 - 0.58. The rank of the entire coal is subbituminous B. based on the ASTM classification. Based on the analysis of gas adsorption shows from the lower coal scam to upper with the range 412.94 - 675.27 SCF / Ton. The upper coal seam of the small gas adsorption while at the bottom of coal seam is large gas adsorption. This change in gas adsorption is caused because the lower coal seam contains pyrite minerals, while the top is rarely found in pyrite minerals. The size of pyrite mineral content will affect the adsorption of methane gas. Keywords: maceral, adsorption, vitrinite reflectant.
