Abstract
This study aims to make a detector for the nominal value and authenticity of money (rupiah currency). The working principle of this tool is as follows: UV LEDs function to provide lighting to objects (money). The light will circulate hidden colors in real money so that you can differentiate real money or money whose authenticity is doubtful. The White LED provides lighting for the object, then the light is received by the TCS 3200-DB color sensor to read its Red, Green, and Blue (RGB). Furthermore, the RGB value will be processed by Arduino Mega 2560 to be compared with the RGB values in the program. The mini DFPLayer functions to play sound according to the sound that has been recorded with the program. Testing the tool is done to determine the percentage of success of the tool in distinguishing between original money and the authenticity of money is doubtful. Testing of 7 (seven) nominal 2016 emission rupiah, namely Rp. 1,000 (80%), Rp. 2,000 (60%), Rp. 5,000 (100%), Rp. 10,000 (100%), Rp. 20,000 (80%), Rp. 50,000 (100%) and Rp. 100,000 (66%), so the average percentage of success of the tool is 83.71%.
