Abstract

Money as a medium of exchange in conducting transactions is also used by persons with disabilities including the visually impaired. Blind people have limitations in the ability to identify the type of money and the authenticity of the money, so they are vulnerable to being confused, taken wrongly, vulnerable to being deceived by counterfeit money and not according to the nominal value. The use of a money detector with speaker output can help blind people to make it easier to process transactions such as trading or other economic activities. The purpose of making this tool is to develop technology for people with disabilities. The method of making this money detector includes literature study and design by trial. To make this tool, several components and modules are needed, such as Arduino Nano as the basis of this tool, ML8511 ultraviolet sensor, ultraviolet LED, TCS3200 color sensor, mini DF player, LCD, and speakers as sound output. The power supply of this tool uses DC 5V, the way this tool works is to start by attaching a banknote object to a board that has been made and designed on top of the sensors, then the ultraviolet sensor and color sensor will automatically detect the banknote, after the sensor detect then the database will match the value created in programming with the banknote object, then the LCD output will display the result and the DF player will pass the sound to the speaker. The results of the research on this tool show success in the trial process, on the results of testing the banknotes applicable in Indonesia such as the nominal Rp 1000, the accuracy rate is at 70% after 10 trials, Rp 2000, Rp 5000, Rp 10.000 is at the level of 80% accuracy, for nominal of Rp 20.000 have the highest accuracy of 90%, and Rp 50.000, Rp 100.000 have an accuracy rate of 60%. The conclusion is that the accuracy level of this tool is quite high, but it still needs to be developed for further research, this money detector is able to function properly.
