Kualitas Serat Limbah Pertanian dan Hasil Samping Pertanian yang Difermentasi dengan Aspergilus Niger pada Aras dan Lama Pemeraman yang Berbeda

Research to assess the effect of fermentation waste Agriculture and agricultural byproducts by A. Niger on various old cedars and different curing the fiber components related to the use of local waste has been carried out from January to March 2012 in the Department of Laboratory Animal Food Technology and Nutrition Faculty of Animal Science, Diponegoro University Semarang. Material research is corn straw, rice straw, rice bran, cassava, pulp brem, tofu, A. Niger. Chemicals used include neutral detergent, acid detergent, Natriumsulfit (Na2SO3), acetone, acetic acid and hot water. Experimental design used was completely randomized factorial design 4x4 each consisting of 3 times. Parameters measured were acid detergent fiber component fiber (ADF) and neutral detergent fiber (NDF). Data processing using various analysis to determine the effect of treatment and if there is a real effect followed by Duncan multiple test area to determine the differences and the effect of treatment on the level of 5%. The results showed that there was no interaction effect of elevated cedar and long curing time starter for the content of NDF and ADF. However, partially significant (p <0.05) to decrease the content of NDF and ADF. It was concluded that the treatment increased the cedar starter up to 6% and up to 21 days curing time partially reduce levels of ADF and NDF. The addition of A. Niger Aras to 4% and the long curing for 14 days each produce the lowest levels of NDF and ADF
