Abstract

This study aims to develop an assessment instrument in the form of a multiple-choice objective test on hydrocarbon material in senior high school chemistry. The research method used is research and development (RD), involving steps such as material analysis, test item construction, validation, field trials, and item analysis. The developed instrument consists of 30 items based on the learning outcomes in the "Kurikulum Merdeka". Validity testing using Pearson correlation shows that 29 out of 30 items are valid (r ≥ 0.388; sig. 0.05). Reliability testing using Cronbach's Alpha resulted in a score of 0.965, indicating very high reliability. These findings suggest that the developed test instrument is valid and reliable for evaluating students' understanding of hydrocarbon concepts.

Abstract

Chemistry education has a strategic role in shaping students'awareness of global sustainability issues such as climate change andpollution. This study aims to analyze the effectiveness of Case-Based Learning (CBL) in integrating sustainability values intochemistry learning, while improving students' scientific literacy andcritical thinking skills. The method used is a literature study byanalyzing various sources, including journals, books, and relatedarticles. The results of the study indicate that the CBL approachsuccessfully connects chemical concepts (eg polymers and greenchemistry) with actual issues such as plastic waste and renewableenergy, so that learning becomes more contextual. In addition, thecombination of CBL with STEM-based Project-Based Learning(PjBL) has been shown to train students in problem analysis, data-based decision-making and sustainable solution development.Implementation challenges include lack of teacher training andlimited resources, which can be overcome through pedagogicaltraining, collaboration with industry, and utilization of technology(such as augmented reality). The conclusion of the study confirmsthat the integration of CBL and sustainability values in thechemistry curriculum not only strengthens scientific understandingbut also shapes students' characters who care about theenvironment. Recommendations for further research include long erm evaluation of the impact of CBL on student behavior as well the development of local wisdom-based modules (ethnoscience)
