Colorimeter is a detector that is used to determine the concentration by analyzing the intensity of light transmitted by the solution. The samples used in this study are harmful and harmless dyes. The light emitted will pass through the sample, so that the beam of light in the sample will be captured by the photodiode sensor. The photodiode sensor functions to convert light into an output voltage. The output voltage will be amplified by a voltage amplifier circuit. The results of the output
