This research to develop simple tools for the analysis of slurry by application of color is derived from the principles of the system color RGB (red-green (R) (G) and blue (B)) in the initial stage will use Green solvents in various variables in the study to find the wavelength of Green solvents by Simeon noble machine UV-spectrophotometer. Discovered that the wavelength of the Green solution absorption maximum is 630 NM. Later, as a select range of slurry concentration in green. It is found that the concentration of the range of green solutions that are appropriate, then the concentration range 0.001 – 0.01 percent by weight per volume, then remove the concentration ranges studied with simple tools. By making the appropriate distance between the camera and find mobile phones with analysis by test tube with a simple tool. It is found that the appropriate term is 3 cm distances, then it is to find the proper distance between the lamp to test tubes, which at this stage in the analysis of conditions is to turn off the lights and turn on the light laboratory laboratory. Which found that the appropriate distance between the lamp tubes reaches 20 cm distance is and check the reliability of the analysis. Found that to find the accuracy of simple tools. The% RSD values less than 2 percent, to find the accuracy of simple tools, the value% RE less than 5 percent, so have taken the simple tool developed to analyze the different color solution. The analytical solution can be found that Carmine. Yellow, Orange, blue, purple, and red. The result is equivalent to machine the Casino, noble-UV spectrophotometer. However, the simple tool developed to Analysis and easy cheap
