Integration of water treatment knowledge using SETS approach in online chemistry learning to improve chemical literacy of students on the aspect of knowledge and context

Chemical science literacy is one of the skills that students must master in the 21st century to solve their daily lives. One of the problems students face in the Delta Mahakam area is the difficulty of getting clean water. This study aims to determine the effect of integrating knowledge in water treatment technology using the SETS approach in online chemistry learning toward students' chemical literacy skills on knowledge and context. The research used the quasi-experimental method with a research design was the post-test only control group design. The populations in this study were all 10th-grade students in SMA Negeri 2 Muara Badak during the 2019/2020 academic year, with 53 students divided into two classes. The sampling technique used in this research was the saturated sampling technique. The instrument used to measure students' chemical literacy skills in knowledge and context was a post-test in the form of essay questions. The results showed that the experimental class's literacy ability score in knowledge and content was higher than the control class. The statistical analysis results using the t-test (tcount 2,134 > ttable, 2,008; α = 0.05) indicates that the integration of water treatment technology using the SETS approach in online chemistry learning affected the chemical literacy skills aspects of knowledge and context. Therefore, the knowledge in water treatment technology using the SETS approach can be integrated with online chemistry learning to improve students' chemical literacy skills, especially in solving the problems of clean water availability in the Delta Mahakam area.
