The Development in technology encourage automation system to use microcontrollers with smaller, cheaper and more efficient advantages. One technology that can apply this system is the coconut shell briquette printer, which is an alternative fuel with high calorific value and is environmentally friendly. This study aims to design and build an Arduino-based automatic briquette printing tool to increase production efficiency, reduce operational costs, and make the work of small and medium enterprises easier. The research methods used is literature studies, field studies, hardware and software design, and tool testing. Main system of this project is a screw drive motor, conveyor, infrared proximity sensor, automatic cutter, and LCD screen to display the amount of production. The test results showing that the tool is able to print briquettes automatically with a higher production rate compared to the manual method. However, several obstacles were found in the tool that was made, especially in the cutting mechanism which was less than optimal. The conclusion of this study shows that an Arduino-based automatic briquette printing tool can be a solution for small and medium enterprises for increasing production efficiency. Suggestions for further development include improving the cutting mechanism, as well as optimizing power to improve the quality and quantity of production.
