Abstract

This study aims to develop a practical work design for creating briquettes from durian peel waste and to identify the development of high school students' creativity through this practical work in the context of project-based learning on petroleum. Adopting a mixed-methods approach, this research involved 48 eleventh-grade students from a high school in South Sumatra. The practical work design encompassed six critical stages: raw material preparation, carbonization, pulverization, mixing, molding, and drying durian peel waste into briquettes. The research comprehensively assessed students' creativity across three dimensions: creative thinking skills, creative attitudes, and creative actions. The results demonstrated significant improvements: creative thinking skills showed an n-gain of 0.59, creative attitudes an n-gain of 0.68, and creative actions an impressive n-gain of 0.84. This approach facilitates a deeper understanding of chemical concepts and aligns with the Merdeka Curriculum's principles of developing 21st-century skills. By integrating contextual learning, environmental awareness, and practical innovation, the study provides a meaningful approach to chemistry education that encourages student creativity, problem-solving, and entrepreneurial thinking while addressing waste management and alternative energy challenges. The research implications underscore the importance of implementing project-based, contextually relevant learning strategies in high school chemistry education to enhance student engagement and skill development.

Abstract

The Project-Based Learning (PjBL) model places students at the center of learning to gain real experience related to environmental sustainability. This study describes the effectiveness of the PjBL model in producing bioplastics from banana peels within green chemistry material to enhance high school students' environmental concern attitudes and pro-environmental behavior. A quasi-experimental method with a non-equivalent control group design was used. The sample consisted of class X.1 as the experimental group and X.2 as the control group, selected through cluster random sampling. Results show the average N-gain of environmental concern attitude in the experimental class was higher than the control class, with an effect size (r) of 0.67 (large category). Pro-environmental behavior also showed a highly significant difference (Mann-Whitney U, Z = -3.932; Asymp. Sig. < 0.05) with an effect size (r) of 0.50 (large category). It is concluded that the PjBL model for producing banana-peel bioplastics is effective in enhancing students' environmental concern attitudes and pro-environmental behaviors
