dc.description.abstractThe potential of jackfruit seeds both in powder form and carbon form activated with HNO3 in adsorption of Rhodamine B from aqueous solution was studied. The synthesized jackfruit seeds were prepared at size that passed at 100 mesh and retained at 200 mesh, for carbon form were carbonized at 400o C for 3 h and the jackfruit seed in powder form and carbon form were activated with HNO3 0,3 M. Surface area of adsorbent was analyzed through methylene blue adsorption tests based on SNI No. 06-3730-1995. Adsorbents were characterized using SEM for surface morphology analysis and FTIR spectroscopy for functional group analysis. Effects of parameters such as dosage of adsorbent and contact time were evaluated and optimized. Based on this study, it was obtained that the activation process was increased the surface area of adsorbent for jackfruit seed powder from 7.8586 m2/g to 8.3862 m2/g and decreased the surface area for jackfruit seed carbon from 4.9015 m2/g to 2.8491 m2/g. The optimum adsorption was achieved for jackfruit seed powder activated HNO3 at 0.9 grams optimum dose of adsorbent and optimum of contact time for 150 minutes, the optimum adsorption efficiency of about 96.53%.en_US
