<![CDATA[Aflatoxin is a metabolite secondary of Aspergillus flavus and A. Parasiticus. Contamination aflatoxin in poultry have an impact on their liver damage. Technique to reduce the effects of aflatoksin can be done by addition of aflatoxin binder. Aflatoxin binder material commonly used still import as glucomannan yeast product (GYP), so we needed study local material that has the potential as a a aflatoxin binder. The purposes is test proximate content and the binding power of flour iles-iles compared to GYP. Sample in research is flour derived from bulbs iles-iles (Amorphophalus oncophylus) and GYP as control. The parameters in research that is the physical characteristics , proximate analysis , glukomannan levels and the ability of binding aflatoksin in vitro between flour iles-iles and GYP. The results of the physical test, the sample has delicate texture and gross energy flour iles-iles not significantly different with GYP. The results of proximate analysis ( the water level , ashes , crude fiber , crude protein and crude fat) show between flour iles-iles and GYP was significantly different, except crude fat that shown the result is no different (p<0,05) .The results of the analysis in the glukomannan levels of flour iles-iles is 52,74 % and GYP 17,36%. Testing the ability bind done with a solution of aflatoksin 2 ml (2.7 ng/ml) and materials binder used is 0 g; 0,0013 g; 0,0027 g and 0,0040 g. The research results show binding aflatoxin by flour iles-iles optimal in heavy 0,0013 g (92,92 %), while binding aflatoxin by GYP optimal in heavy 0,0040 g (87,71 %). The ability binding aflatoksin flour iles-iles in proportion to GYP so that can be used as a alternative binder in feed. Keyword: Iles-iles (Amorphophallus oncophylus), aflatoxin, Glucomannan ]]>
