Abstrak

- Grounded on BLHD's report of South Borneo on 2009, Fe contents in Barito river achieve 2,5455 mg/L. This level pass by KEPMENKES on 2002 which only permit Fe contents in water as many 0,3 mg/L. The goals of this research are to study ability of banana stem to decrease Fe contents in water sample of Barito river. Knowing the best adsorbent condition to decrease Fe contents in Barito river based on variations of activation process, kind of activator, adsorbent diameter size, stirring of velocity and adsorption duration as well as to find water of Barito river which appropriate with clean or drink water standart based on KEPMENKES on 2002.This research started with adsorption process and finishing with filtration process. Banana stem is washed until clean and then cut to small slice to abridge vaporization of water contents when is hoted under the sun. The dried banana stem be broken with blender. Banana stem is screned to find diameter size as big as 20, 30 and 40 mesh. Then, banana stem is activated using KMnO4 ­0,1 M dan ZnCl2 0,1 M solution during 24 hours. Whereas in physics activation, banana stem is pyrolysed during 30 minute at 500oC. Activated carbon is used to adsorption with some variation. The result will test use spectofotometry.Result of this research indicate that banana stem can decrease Fe content in water of Barito river. Activated carbon with size 40 mesh which use physic-chemical activation with KMnO40,1 M solution as well as 150 rpm strring velocity and ahour adsorption duration give the best result.
