The objective of this research is to investigate whether incorporating a resource-based learning model (RBL) in the Biology subject at SMAN 1 Padang Ganting has an impact on learning outcomes of students. The research employed a Quasi-Experimental method utilizing a posttest-only control design. The sampling technique is total sampling. Data were obtained using tests, observation, and documentation while data analysis techniques used Dependent sample ttests and Independent sample t-tests. The subjects in this study were Class XE 1 with 29 people as the experimental class and Class XE 2 with 30 people as the control class. Based on the results of the study, hypothesis testing using the independent samples t-test method assisted by SPSS 25, the results of the t-test calculation have a Sig-(2-tailed) value of 0.002 <0.05 with a real level of α = 0.05. Therefore, the null hypothesis (H0) is refuted, and the alternative hypothesis (H1) is accepted. This indicates that students in the experimental class, which implemented the resourcebased learning model (RBL), achieved higher learning outcomes compared to students in the control class. Therefore, it can be concluded that the resource-based learning model produces better learning outcomes for students in XE 1 SMAN1 class in Padang Ganting West Sumatra. Based on these results, schools can consider whether they can use this learning model to improve student learning outcomes.
