Abstract
Chicken feathers contains about 4-6% of total weight of chicken are most influential waste by-product from poultry farm and slaughter. Keratin protein is a fibrous protein that primar constituen of featrhers and is used in several application. This present work, protein was extracted from waste chicken feather and then protein powder was produced from drying of protein solution extract. The objective of this research was characterization the protein extract and to study the influence concentration NaOH anf time on yield protein extract. Experimental results on extrcation protein shows that at concentration NaOH was 1,75 N and 90 minute, yiels of crude protein was 94,8%. This is concluded that hydrolytic process can used to produced soluble protein. Caracterization powder protein extract by Fourier-Transform Infrared Spectroscopy (FTIR) shows that the protein extract remained their characteristic as protein.
