Abstract

Adsorpsi Remazol Yellow FG oleh adsorben selulosa bakterial nata de coco telah dilakukan. Adsorben selulosa bakterial nata de coco dibuat dari nata de coco kering yang telah dihaluskan dan lolos ayakan 30 - 40 mesh. Adsorpsi dilakukan dengan metode ruah/batch dengan variasi pH, dosis adsorben, waktu kontak, dan konsentrasi adsorbat. Dari hasil percobaan diperoleh kondisi optimum adsorpsi pada pH 2, dosis adsorben 0,1000 g, waktu kontak 60 menit dan konsentrasi awal larutan 1509,085 mg/L dengan kapasitas adsorpsi sebesar 44,357 mg/g. Kinetika adsorpsi Remazol Yellow FG oleh adsorben selulosa bakterial nata de coco mengikuti model kinetika orde satu (K = 0,0564), serta adsorpsi isotermalnya mengikuti persamaan isotermal Langmuir dengan nilai KL = 43,860 L/mg dan b sebesar 0,056 mg/g. Penelitian adsorpsi Remazol Yellow FG dalam limbah batik tulis oleh adsorben selulosa bakterial nata de coco juga telah dilakukan pada kondisi adsorpsi optimum dan didapatkan hasil prosentase adsorpsi sebesar 26,506% dan kapasitas adsorpsi sebesar 44,161 mg/g ==============================================================================================Adsorption of Remazol Yellow FG using nata de coco bacterial cellulose as adsorbent has been done. Nata de coco bacterial cellulose as adsorbent was made from dry nata de coco that has been mashed and pass 30-40 mess sieve. Adsorption was done using implementing batch method with various of specified pH, adsorbent dosage, contact time, and adsorbat concentration. Based on the result of the study, the optimum condition of adsorption were pH 2; 0,1000 g of adsorbent dosage; 60 minutes of contact time, and 1509,085 mg/L of initial solvent concentration with 44,356 mg/g adsorption capacity. The kinetic adsorption of Remazol Yellow FG that performed by nata de coco bacterial cellulose as adsorbent was following first order kinetics model (K = 0,0564). The isothermal adsorption was following Langmuir isothermal equation with KL = 43,860 L/mg and b = 0,056 mg/g. The adsorption study of Remazol Yellow FG on written batik waste using nata de coco bacterial cellulose as adsorbent has also been done on optimum adsorption condition that was resulting 26,506% on adsorption percentage and 44,161 mg/g on adsorption capacity
