This research was conducted in soil chemical laboratory, Faculty of Agriculture, Andalas University, from December 2016 untilMay 2017.The purpose of this research are todetermine the level of activeness ofpowder coal Sub-bituminouscoal withSodium Hydroxide (NaOH) and to determine the appropriate dosage of the mixture in improving the chemical properties of Ultisols. This research was conducted in 2 stages: first stage study with 10 treatments (1% to 10% (w/w) NaOH) and the second stage study on soil using 15 treatment combinations (3 doses of powder sub-bituminous coal with 5 doses of NaOH). The results of the first stage of research is the addition of NaOH in Sub-bituminous to increase the activity of powder Sub-bituminous coal with parameters of pH, CEC, and increases the number of O-H, C=O, and CH3 groups.The results of stage II studies is the provision of a mixture of 20 ton (ha)-1 powder Sub-bituminouscoal and10% of NaOH were able toincreases the pH of H2O, CEC,organic-C, Available-P,andTotalN Ultisol each of 1.49 units, 28.08 me.100g-1, 1.63 % C, 2.37 ppm P, 0.06% N, and decreases Al-exch Ultisol by 1.17 me.100g-1and , SARUltisolby0.03,andESPUltisolsby0.82%comparedtonaturesoil.
