Coffee grinding is an important process in the coffee industry to produce coffee grounds that are smooth and in accordance with consumer preferences. The motor power required to operate a coffee milling machine becomes a key factor in determining the performance and operational efficiency of the machine. This study aims to determine the time and energy needed to grind several kinds of coffee in the grinding process. The method of calculating the time and energy needed to grind coffee beans becomes very important in order to be able to grind coffee. From these calculations, it is calculated based on the amount of coffee to be ground and the time required for grinding.The calculation results show that using the required motor power increases with an increase in the amount of coffee to be ground and a shorter grinding time. Therefore, the selection of motor power in accordance with the capacity and production needs of coffee grinding machines is crucial to ensure optimal performance and operational efficiency.[5][6] This research contributes to the understanding of those influencing the timing of coffee grinding, in selecting motor powers that can determine the time for grinding their production.[7][8][9].
