| dc.description.abstract | In the palm oil processing factory, many macro-mushrooms of various sizes, shapes and colors grow quickly in empty fruit bunches. The potential of fungal biomass as a biosorbent is known for its ability to adsorb heavy metals. Conditioning of biomass used as a medium for adsorbing heavy metals is carried out by activation using alkaline solution (NaOH). One alternative for the separation of heavy metals from industrial waste that is effective, inexpensive, and environmentally friendly with biosorption processes, where the process uses microorganisms as biosorbents of heavy metals such as algae, fungi, and bacteria. The research objectives are: 1) macroscopic and microscopic identifying fungi that grow in empty fruit bunches. 2) Characterization of fungi using FTIR analysis. 3) Calculate the efficiency and adsorption capacity by fungi under conditions of activation using NaOH with variations in concentration and not activated on Cr (VI) metals. The results of macroscopic and microscopic identification of fungi that grow on empty fruit bunches is the fungus Coprinus comatus. After analysis using the fungus Coprinus comatus contains functional groups such as hydroxyl, alkenes, carboxylates, esters, amines and alkaline which qualify as biosorbents. Furthermore, the biosorbent is activated using NaOH with a concentration variation of 0.3 N; 0.5 N and 0.7 N and without activation. The best adsorption of Cr (VI) metal in the condition without activation. The highest efficiency values are 48.36% and 11.42 mg / gr adsorption capacity by the Coprinus comatus fungus. Biological waste treatment that uses fungi as biosorbents to adsorb heavy metals has the potential to be developed. | en_US |
