Abstract

This study aims to determine the quality of Sumbawa wild horse milk with viscosity and dielectricity methods. The sample used was Sumbawa wild horse milk with concentration variations from 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. Variations in the concentration of wild horse milk are mixed with soda. Based on the results of the measurement of the viscosity coefficient, the coefficient value at a concentration of 100% shows the viscosity coefficient value of 1.299 Poise and takes 1.52 seconds. At the smallest concentration variation, which is 10% with a mixture composition of 45 ml of wild horse milk and 5 ml of solvent, it has a viscosity coefficient value of 0.910 Poise with a time of 1.12 seconds. Furthermore, at the dielectricity measurement, the dielectric constant value for 100% concentration was 2.63 x 106. Furthermore, at the 10% concentration variation, the dielectric constant value was 1.68 x 107. The results showed that the higher the concentration of the solution, the higher the coefficient. solution viscosity. This is because the density of the solution is directly proportional to the viscosity coefficient of the solution. However, on the dielectricity of the solution, the higher the concentration of the solution, the lower the value of the dielectric constant of the solution. This is because the density of the solution is inversely proportional to the dielectric constant of the solution, so the higher the concentration of the solution, the higher the density of the solution so that the dielectric constant of the solution is lower.
