Of course this is very inefficient considering the weather conditions are often erratic. there will often be a delay in lifting the clothesline and it will be very detrimental if the cinnamon bark is not dry optimally. Because it will have a big effect on the quality of the product later. In this modern era, microcontroller/automation technology is growing in all fields, ranging from industry, education, health and others. So we need a system that can dry and lift / protect the drying automatically. This study uses a prototype system development method where the first step is system requirements analysis, at this stage the aim is to analyze the drying system that is currently running at the company that processes cinnamon bark and analyze the proposed system in the automatic drying system. the second is system design, at this stage explains how the process of designing systems, hardware and software (programs). The third is system testing, at this stage discusses the results of testing the entire system. The fourth stage is implementation, at this stage explaining how the development process and comparing the old system with the new system. The result of this research is that the workers in the company will be more free to do other jobs and will not worry if it rains at any time because the system will automatically pull the clothesline to a shady place. From the results of the tests that have been carried out, the success rate of the design tool for automation drying cinnamon rack stacking using the Arduino Uno R3 microcontroller based on android is 90%.} }
