Abstract

Teaching senior high school students green chemistry can contribute to future scientists and professionals who are responsible for safer, less hazardous chemistry. Plastic, known for its durability, affordability, and lightweight properties, is integral to daily life across industries, including housing, healthcare, fashion, sports, and transportation. However, the plastic industry poses significant economic and environmental challenges, raising concerns about its sustainability. To address these issues, this research focuses on the transformation of orange peel waste into a fine powder to develop a biobased, biodegradable plastic. The study conducted a soil burial test over a continuous 14-day period, revealing that an increased quantity of orange peel powder positively influenced the biodegradability of the bioplastic. Enhanced biodegradation was observed with higher concentrations of orange peel. The implementation of bioplastic experiments in the classroom received positive feedback from students, as evidenced by high ratings across various statements. Overall, the findings suggest that the experiments were not only engaging but also effective in shaping students' perspectives on plastic and science.

Abstract

A student's motivation influences students' self-regulatory abilities, and significantly impacts their attitude towards scientific concepts, contributing to a more enriched and successful learning experience. This research explores the correlation between motivation and self-regulation in science learning among junior high school students. The research methodology employed in this study adopts a quantitative approach with a survey research design. This research found that the average learning goal orientation is 4.12, task value is 3.97, and self-efficacy is 3.75. The total average for the dimensions of motivation and self-regulation is 3.95 and 3.89 respectively. These scores indicate that the motivation and self-regulation in science learning among junior high school students are categorized at a high level. Furthermore, there is a significant correlation between motivation dimensions (learning goal orientation, task value, and self-efficacy) and self-regulation in science learning. Based on the students’ answers to open-ended questions, they are motivated to learn science because learning science is interesting and fun. Meanwhile, students who feel unmotivated to learn science find it challenging, especially when dealing with formulas and calculations. However, despite the lessons' difficulty, students still try to study because most of them desire to achieve good grades in science lessons.
