The population of this study consisted of class X IPA SMA Negeri 1 Buko students. The sample consisted of two classes which were selected using the random intact class technique with 25 people each. Data collection techniques using pretest and posttest. The test results of the hypothesis t test with a significant level of α = 0.05, the value of tcount = 24.8 is greater than ttable = 2.010.
