The purpose of this study was to determine the knowledge in critical thinking of physics education students about the use of solar cell technology. This study uses a qualitative approach. The subjects in this study were 40 students of physics education at the University of Jember. Critical thinking indicators that must be studied are analysis, explanation, interpretation, evaluation, inference, and self-regulation. The research instrument used a test given via google form. The results showed that the percentage of students who were able to answer questions correctly was still relatively low. This shows that the knowledge of physics education students at the University of Jember about solar cell energy is still very lacking.
Wind is a gas flow that is on a large scale and in large quantities caused by the rotation of the earth and the difference in the air around it. This study aims to analyze students' knowledge about the potential use of wind as an energy source along the southern coast of Java. This research method was qualitative with respondents from physics education students at the University of Jember batch 2020. The research data collection uses a questionnaire (Google Form). The wind potential around the southern coast of Java has an average speed of 3-8 m/s. In this area, it is very suitable to build a wind power plant because the average wind speed to drive the wind turbine in this power plant is between 5-8 m/s. Students have good knowledge about the potential use of wind as an energy source along the southern coast of Java.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
