Abstract

Water turbidity testing is needed in the process of water treatment for water to be consumed. Therefore, an effort is needed to develop a tool that serves as a detector of turbidity of water, in order to set a standard parameters of water clarity that can be consumed by the community. In this research, the physics parameters related to water consumption, ie turbidity or turbidity are discussed. Turbidity describes the optical properties of water determined by the amount of light scattered by the materials present in the water. The direction of the transmitted light path will change when light touches the particles in the water column. The particle size affects the value of turbidity, where in the testmilk powder and coffee are suspended matter that causes water turbidity. The particle size of milk powder is smaller than coffee, therefore, the light is more scattered in milk solution than with turbidity value about 3.01 NTU while coffee 2.67 NTU at 5 gr / l solution.
