Abstract

The aim of the research was to find out the difference in learning outcomes before and after applying the Problem Based Learning (PBL) learning model to the acid-base material of class X Agriculture SMK Negeri 1 Biaro. This research was conducted in class X Agriculture at SMK Negeri 1 Biaro in the 2022/2023 academic year. A total of 16 students of class X Agriculture were selected as the research sample. Based on the test data for the hypothesis t test, a tcount value of 38.077 is obtained with a ttable value of 2.042. And the significant level used is α = 0.05 with degrees of freedom n1 + n2 - 2 (16+16-2) = 30. By looking at the values ​​of tcount and ttable, tcount > ttable means that H0 is rejected and H1 is accepted. Based on the increase test (N-gain) obtained 0.75 with high criteria. Thus it can be concluded that the Application of the Problem Based Learning (PBL) Learning Model on Acid-Base Reaction Material has an effect on Student Learning Outcomes at SMK Negeri 1 Biaro.
