Meanwhile, the level of effectiveness measured through pre-test and post-test in the initial field trial of FKIP Unej students showed an increase in learning outcomes reaching 27.89% with the results of calculating the t-test obtained that the t-count value was 13,101 greater than the t-table, which was 2.003. In the follow-up field trial of class X students, it showed an increase in learning outcomes reaching 32.41% with the results of calculating the t-test obtained that the t-count value was 21.005 greater than the t-table, namely 1.990. Thus, it means that PAI teaching materials with an interdisciplinary approach that have been developed are proven to be valid, interesting and effective in improving student learning outcomes at SMKN 1 Singosari.
