Abstract
One of the poultry businesses that is developing in Indonesia is duck farming. Duck farming has a relatively smaller risk, so it has great potential for development. One solution that is being developed is the use of keratin contained in duck feathers as an adsorbent that can be used to reduce metal levels. This research aims to determine the optimum volume and adsorption capacity required in the manganese ion adsorption process. The optimum volume and manganese adsorption capacity were measured using Atomic Absorption Spectrophotometer (AAS) to determine the amount of manganese ions that were adsorbed with the duck feather keratin-Na2S2O5- HDPE composite adsorbent. Determination of the optimum volume is carried out with volume variations of 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, 2.0 liters, while determining Adsorption capacity was carried out using a 100 ppm manganese solution flowed at a speed of 0.2 liters/minute. The results of this research show that the optimum conditions for manganese ion adsorption occur at a volume of 1.2 liters of 82.248 mg/L and an adsorption capacity of 17.029 mg/g. The conclusion of this research is that HDPE duck feather composite can absorb mn metal ions, where the resulting adsorbent will have strong adsorption capacity and can bind metal ions.
