Abstract

Pendahuluan: Minyak jelantah merupakan limbah rumah tangga yang sering dibuang sembarangan dan berpotensi mencemari lingkungan serta membahayakan kesehatan. Di Desa Majalengka Kulon, tingginya angka kemiskinan dan rendahnya kesadaran masyarakat terhadap pengelolaan limbah menjadi tantangan tersendiri. Studi ini bertujuan untuk mengedukasi masyarakat mengenai pengelolaan minyak jelantah menjadi sabun sebagai solusi terhadap pencemaran lingkungan dan peningkatan ekonomi lokal. Metode: Pendekatan partisipatif melalui pelatihan pembuatan sabun berbasis minyak jelantah, sosialisasi dampak lingkungan, serta dokumentasi kegiatan dalam bentuk publikasi ilmiah dan media massa. Hasil: Masyarakat mampu mengelola minyak jelantah menjadi sabun padat yang layak dan bernilai jual, serta menunjukkan peningkatan pemahaman terhadap dampak lingkungan dari limbah minyak goreng. Kesimpulan: Pengolahan minyak jelantah menjadi sabun dapat menjadi solusi terpadu dalam mengatasi pencemaran lingkungan dan memberdayakan ekonomi masyarakat desa.

Abstract

Understanding students’ cognitive structure is essential for improving conceptual learning in science, particularly in challenging topics such as the rate of reactions. However, many students struggle with fragmented knowledge and misconceptions in this area. This study investigates how the 8E Learning Cycle model supports the development of students’ cognitive structure, analyzed through the flow map method. The participants were 33 Senior high school students, and a qualitative approach was employed using multiple data sources (flow maps, worksheets, interviews, journals, observations, and comprehension tests). Cognitive structure was examined based on Tsai’s six variables: extent, richness, integration, misconceptions, information retrieval rate, and flexibility. Results indicated that at the beginning of instruction, students’ average scores on cognitive structure variables were low, while misconceptions were frequent. After engaging in the 8E Learning Cycle, students demonstrated notable improvement across all variables, accompanied by a marked reduction in misconceptions. This study provides empirical evidence that the 8E Learning Cycle model effectively strengthens students’ cognitive structures in science learning, offering a practical framework for addressing conceptual difficulties in reaction rate topics
