Practical support by using one to one which was tested on three students with an average of 4.3 included in the very practical category and a small group with an average of 4.4 including very practical categories. In the trial of problem-based cellular learning media learning in 34 students of class XI had the potential to increase student motivation, as evidenced by the learning motivation level of 72.9% included in the high motivation category, so that it corresponds to the interpretation of the 60-80 score interpretation. % is high motivation.
