The government provides different trash cans so that people can dispose of garbage according to the type of garbage and waste will be easily recycled, and this is done in order to be a smart city. However, there are some people who do not understand in which vats they have to dispose of so that in the end they immediately throw garbage in any barrel without seeing the type of garbage in each trash can. This study aims to create a trash can that can determine the type of waste that is discarded and automatically dispose of it in the right barrel. The research method used is device design, device making, data retrieval, and data analysis. So that the results of this study are that it can be made a smart trash can prototype to be implemented in smart city based on arduino and android. Which later can also be a device for education about the type of garbage in children from an early age.
