Implementation of Project-Based Learning on Alternative Energy Materials to Enhance Class X Students' Cognitive Learning Outcomes at SMA Negeri 1 Perhentian Raja

The purpose of this research is to characterize and ascertain how project-based learning improves cognitive learning outcomes for students. The quasi-experimental research design are employed. The X-grade children of SMA Negeri 1 Perhentian Raja made up the study's population, while the X2 and X5 classes, which included 33 and 32 students respectively, served as the study's samples. Primary and secondary data are the two types of data collection methodologies. Descriptive and inferential analysis are two methods of data analysis. The group that used project-based learning had an average score of 60.7, falling into the "fairly good" category, according to the statistics. In contrast, the group that used traditional learning had an average score of 51.0 in the category of fairly good. A sig value was obtained from the hypothesis testing findings using the Independent sample t-test. There is a statistically significant difference between project-based learning and standard learning classes (2-tailed) 0.002 <0.05). These findings suggest that project-based learning on alternative energy sources can enhance the cognitive learning outcomes of SMA Negeri 1 Perhentian Raja class X students.
