Milk quality test using lactose, specific gravity and fat test approaches at the Kertajaya Village Cooperative Unit, Kediri

The quality of fresh milk based on SNI 2011 regarding fresh milk requirements includes physical, chemical and the number of microorganisms. One of the physical properties of milk can be seen from the density test. The chemical properties of milk can be seen from the lactose and fat rate. The lactose test is by means of titration of the filtrate resulting from filtering milk which is free from any content other than lactose. Density test using a lactodensimeter. Fat test using the Gerber method. From the results of research on the quality of cow's milk which was carried out using the lactose test approach, density and fat obtain average results of 3.98% of lactose rate, 1.0259 g/ml of density and 2.7% of the at rate in VUC Kertajaya is good and close to the criteria according to SNI 2011. This can affect the selling price of milk from farmers in VUC Kertajaya.
