Adsorption of procion red dye has been done from songket industry liquid waste using eggshell. Eggshell was activated using activator of NaOH 15%. In this research, the effect of eggshell weight, contact time, particle size of adsorbent and pH was analyzed to determine optimum condition. The result showed that the optimum adsorption using eggshell are weight at 0.95 gram, contact time at 90 min…
