Judul: Pendugaan Kadar Neutral Detergent Fiber dan Acid Detergent Fiber pada Pakan Berdasarkan Hasil Analisa Proksimat
Abstrak: Feed is an important component in animal husbandry industry. Feed quality can be evaluated by physical characteristic, chemical composition and biological values. Proximate analysis is one of chemical analysis to counting chemical composition in the feed. Van Soest analysis is one of chemical analysis to evaluate fiber in the feed. This study was aimed to determine the relationship beetwen proximate analysis and Van Soest’s fiber component in feed and to predict Van Soest’s fiber component (NDF and ADF) from proximate analysis component such as Ash, Crude Protein (CP), Ether Extract (EE), Crude Fiber (CF) and Nitrogen Free Extract (NFE). This study used database of feed ingredients from Laboratory of Feed Science and Technology, Departement of Nutrition and Feed Technology, Faculty of Animal Husbandry, Bogor Agricultural University. Data were analyzed by correlation analysis and regression (linier regression with single and multiple variables). Accuracy levels of the relationships between variables were expressed as coefficient determination (r2), P Values and Root Mean Square Error (RMSE). The result showed that Neutral Detergent Fiber (NDF) had a strong correlation with Ash, Extract (EE), Crude Fiber (CF) and Nitrogen Free Extract (NFE). Acid Detergent Fiber (ADF) component had a strong correlation with Ash, Crude Fiber (CF) and Nitrogen Free Extract (NFE). NDF can be predicted using a model NDF = -3.925 + 1.64 Ash + 1.528 CF – 0.02 EE + 0.399 NFE (r2=0.814; P=0.002; RMSE = 14.20) and ADF can be predicted using a model ADF = 24.937 + 1.082 Ash + 0.645 CF – 0.077 NFE (r2=0.319; P<0,001; RMSE=12.67). It concluded that proximate analysis component can be used to predict Van Soest’s component in the fee

Judul: Verifikasi Metode Analisis Serat Pangan Dengan Metode AOAC Dan Asp Terhadap Parameter Repeatability, Selektivitas, Dan Ruggedness
Abstrak: Methods of analyzing dietary fiber (DF) have undergone extensive development in the last two decades. At present, the most widely used methods are the enzymatic-gravimetric AOAC official method and the enzymatic-chemical Englyst method. Enzymatic-gravimetric was used in this research because of its economic value. New modifications of the AOAC method are continuously being proposed by researchers. We need to ensure that the method has good performance by verification method. The purpose of this study was to verified enzymatic-gravimetric method for analyzing DF. Four kind of food, raw peanut, raw soybean, carrot, and oat were analyzed for total DF, soluble DF and insoluble DF content by two current enzymatic-gravimetric methods; AOAC Official Methods (1999) and the Asp Method (1992). The results obtained by these two methods were compared. Results for raw soybean were significantly different while other samples were relatively similar. Different enzyme used in two methods leads to variance of DF content for high protein sample. Asp method could efficiently hydrolyze protein because it has two enzyme hydrolyzing step. Ruggedness test was carried out to find the best concentration of ethanol for precipitate SDF between 95% and 78%. Ethanol 78% could precipitate SDF.
