Abstract

The one way to control microorganism can be done with sterilize, such as ultraviolet radiation. The aim of this research is knowing how long ultraviolet radiation for chicken flesh and the effectiveness of it for inactivation salmonella sp bacteri. Methode used is equality single linear regretion. Paraeter of monitoring is amount of salmonella sp. bactery and total of bactery (TPC). Rate of inactivation salmonella sp. bactery in liquid culture sample is (μ)= 0,0106 CFU/second with kinetic model y= 0,0106x + 80738 value R2= 0,9635, rate inactivatio salmonella sp. bacteri in media of flesh chicken sampel SSA is (μ)= 0,0156 CFU/second with kinetic model y= 0,0156x + 5,767 value R2= 0,3373, and rate in activation total bacteri in media of flesh chicken sample PCA is (μ)= 0,04 cfu/ml with kinetic model y= 0,04x + 6,6924 value R2= 0,9309. Value D for liquid culture sample of salmonella sp. bacteri is D=94,33 second, value D for the best flesh chicken sample SSA is D= 64,10 second, and value D for media of flesh chicken sample PCA is 25 second.
