<p>This study aims to determine whether the results of class X students learn physics by using problem based learning based LKS get better results than the conventional learning in SMAN 1 Batipuh. This research is quasi-experimental research. As the population of this study were all students of class X consists of nine classes taken at random, taken two classes will be assigned as the control class and experimental class. The sampling technique using simple random sampling when members of the population considered to be homogeneous, measures of sampling there are four phases: (1) collecting the value of daily tests of students, (2) test of normality (3) to test the homogeneity (4) analyzing the variation, Results of the study were taken from 33.33% yield cognitive learning, 33.33% affective domain of learning outcomes, 33.33% psychomotor learning outcomes. Obtained an average of learning outcomes experimental class and control class 68.49 73.19 hypothesis testing performed using t-test, from the calculation, t = 3.26 and table = 2.00. Because t count > t table accepted hypothesis can be summed result of learning physics class X SMAN 1 Batipuh using physics-based LKS problem based learning is better than conventional learning.</p>
