Use of rice straw as a biosorbent for water treatment in batik industry is not fully developed. Liquid waste for the colour’s adsorption using rice straw biosorbent represented by methylene blue solution. Rice straw biosorbent has been activated by HNO3 1 M and NaOH 0,75 M. Then characterized using Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM EDS) dan Fourier Transform Infrared (FTIR) Spectroscopy. The variation of dosage and drying temperature applied to know the optimum dosage for utilization of biosorbent and optimum drying temperature for biosorbent synthesis. The equilibrium were fitted to Langmuir isotherm and Pseudo Order 2 kinetics. The optimum adsorption obtained in 1,67 gr/L biosorbent with 100ºC drying temperature in 4 ppm methylene blue waste simulation solution with 95.27% adsorption capacities and 4 ppm batik industrial waste solution with 30.59% adsorption capacities.
