This research has studied the efficiency of dye adsorption with coconut coir pith. The input is the pH contact time adsorbent dosage The initial concentration of the dye solution affecting the optimum conditions. In addition, Also studied the isotherm adsorption and kinetics adsorption of dyes. The batch experiment and analyze the concentration of dye and the remaining after through adsorption process with UV-Vis Spectrometer. The results showed that increasing the amount of coconut coir pith and initial concentration of the dye. The percentage of adsorption and adsorption ability increase. Adsorption isotherms and kinetics adsorption equation model consistent with Langmuir equation and Pseudo-second Order respectively. The maximum adsorption efficiency (Qm) of 357.1429 mg/g
