Tissue Preservation Index (TPI) and Gelification Index (GI) with the Quality of Coal as well as the Connection to the Acid Water Mining Dian Agus Widiarso

This research focuses on the coal environment, especially the relation between the depositional environment (TPI-GI) with coal quality and acid water mining. Tissue Preservation Index (TPI) and Gelification Index (GI) are secondary analyzes of the coal depositional environment. The analysis of TPI-GI was carried out based on the analysis of Diesel, 1986. Coal Quality and Acid Water Mining have a relation, especially where coal is deposited, therefore this research studies further how these relations are related. In addition, this study explains a little about coal and its quality and how to correlate the two using the trendline polynomial method.
