While the influence of variable X (the use of game applications on smartphones) on the Y variable (learning outcomes) was 49.4%. With these results, the alternative hypothesis is accepted and the null hypothesis is rejected. In other words it can be concluded that there is a significant influence on the use of game applications on smartphones on the learning outcomes of PGSD STKIP PGRI Trenggalek student learning outcomes.
