<![CDATA[This study was motivated by the low value oflearning outcomes of students in chemistry subjects, especially the material ofsalt hydrolysis and also never used Problem Based Learning-based LKPD onsalt hydrolysis material. This study aims to test how effective Problem Based Learning based LKPD on salt hydrolysis materialis on the learning outcomes of Phase F high school students SMAN 1 Lembah Melintang. The type of research used is quasi experiments with a non-equivalent control group design. The sampling technique usedpurposive sampling technique with two sample groups, namely class XI F3 as the control class and XI F4 as the experimental class. The control class was given treatment using teaching materials in the form of printed books with conventional learning models and in the experimental class was given treatment in the form of LKPD with Problem Based Learning learning models. The instrument used in this study was a written test question with a number of questions as many as 25 objective questions and 2 essay questions. In the research results of the independent sample t-test test with the help of the SPSS application shows the results that Thitung>Ttabel is 6.185>1.997 which means that there is a significant difference between the control class and the experimental class. So it can be concluded that the use of Problem Based Learning-based LKDP is proven effective in improving student learning outcomes on salt hydrolysis material at SMAN 1 Lembah Melintang.]]>
