Dye waste is one of the largest issues in textile manufacturing company because the waste is clearly identified by human eye and not easily biodegraded. One of the most significant treatments is to remove it from water with dye adsorbent. The adsorption characteristic of Azo (Direct Red-31), one of the most used dye substances in industry, is investigated further in this research. Among several possible adsorbent materials from biosilica, rice husk ash is used because of its abundance in Indonesia. This experiment has been run in batch process with dye concentration varying from 20 ppm, 40 ppm, 60 ppm, 80 ppm, to 100 ppm. The adsorbent mass was also varied from 2 g/L, 4 g/L, 6 g/L, 8 g/L, to 10 g/L. Equilibrium model is determined by running three commonly used models in literature: Linear, Freundlich, and Langmuir. For the mass transfer coefficient determination, the external adsorption model is used. The experiment results proved that the equilibrium model of Direct Red-31 and rice husk ash follows the Langmuir model, as it had been expected, with the mass transfer coefficient (k c ) of 2x10 -5 cm/min.
