The rapid development of industrial sector gave not only positive impact on national income but also a negative impact on the environment. Iron (III) heavy metal ion is one of harmful metal ion for biotic creatures and human. In order to control the metal ion in wastewater, adsorption method was introduced. Andisol soil (AndS) containing allophane and sugar palm fiber (SPf) having cellulose are potential materials utilized as an adsorbent for iron metal ion removal in aqueous solution. In this study, the AndS/SPf composite was successfully fabricated and characterized as well as optimized as an adsorbent. The adsorption process was performed using a batch method by varying pH condition, calcination temperature, AndS:SPf ratio and contact time. This study obtained that the optimum pH by 5, calcination temperature by 100°C, AndS:SPf ratio by 1:3 and contact time by 45 minutes. This research also studied the isotherm adsorption, i.e. Langmuir and Freundlich model and found that the adsorption followed Freundlich model.
