This study aims to determine the comparison of student learning outcomes between the use   of the Problem Based Learning (PBL) model and the Discovery Learning model  on virus materials in class X of SMA Negeri 1 Percut Sei Tuan. This study is a type of quasi- experimentalresearch with a pre-test, post-test, non-equivalent group design. The research was carried out from February to October 2025 at SMA Negeri 1 Percut Sei Tuan. The population in this study is all students of class X of SMA Negeri 1 Percut Sei Tuan, with the research sample consisting of two experimental classes. Experimental class 1 uses the Problem Based Learning (PBL) model, while experimental class  2  uses    the  Discovery Learning  model.  Data collection is carried out through pretest and posttest tests to measure student learning outcomes. Based on these results, it can be concluded that the Problem Based Learning  model is more effective than  the Discovery Learning  model in improving student learning outcomes on  viral  materials and  is  able  to  encourage students' activeness, motivation, and critical thinking skills in biology learning.
