Critical thinking is a key competency for 21st-century students, essential for logical reasoning, decision-making, and academic success. However, studies indicate that Indonesian students often exhibit low levels of critical thinking. Chemistry, particularly topics like oxidation-reduction reactions, offers real-life applications, such as waste oil disposal, that can be leveraged to improve these skills. This study aims to analyze the effectiveness of integrating dilemma stories into project-based learning (PBL) to enhance students' critical thinking skills in the context of oxidation-reduction reactions. The study was conducted at SMAN 77 Jakarta with 36 students from Class X Mathematics and Natural Science 2. A qualitative approach was used, with data collected through observations, reflective journals, interviews, and critical thinking tests. The integration of dilemma stories in PBL was implemented through five stages: value reflection, problem-solving, project development, monitoring and evaluation, and transformation. The findings indicate significant improvements in students' critical thinking, creativity, collaboration, and problem-solving skills. Based on test results, students achieved level 3 (Acceptable) in critical thinking. The approach also enhanced their understanding of chemical concepts and awareness of addressing real-world problems. The integration of dilemma stories within PBL has proven effective in fostering critical thinking and other 21st-century skills in chemistry learning. This approach can serve as a model for innovative educational practices in STEM subjects.

Pendahuluan: Limbah rumah tangga seperti sisa sayur, buah, dan nasi basi dapat diolah menjadi kompos cair yang bermanfaat bagi tanaman, sekaligus mengurangi penumpukan sampah dan pencemaran lingkungan, termasuk penurunan kualitas air bersih. Studi ini bertujuan untuk meningkatkan kemampuan guru kimia dalam mengintegrasikan konsep kimia dengan praktik sehari-hari serta mendorong pembelajaran kontekstual di kelas. Metode: Pretest, sosialisasi, demonstrasi, postest, diskusi tanya jawab, dan evaluasi. Sebanyak 18 guru kimia dari MGMP Kimia Jakarta Timur 2 mengikuti kegiatan ini. Para peserta dilatih mengelola limbah rumah tangga menjadi pupuk kompos cair dan mempraktikkannya dalam pembelajaran melalui praktikum, sehingga turut mengurangi sampah di lingkungan sekolah. Hasil: Peserta berhasil membuat pupuk kompos cair dari limbah rumah tangga serta memahami proses dan bahan yang digunakan. Kesimpulan: Pelatihan ini berhasil meningkatkan keterampilan dan pemahaman 18 guru kimia dalam membuat dan menggunakan kompos cair, termasuk penggunaan EM4, serta mendukung upaya pengurangan pencemaran lingkungan.

This research aims to determine the influence of the classroom environment using the My Class Inventory-Short Form instrument on learning outcomes. The research method used is a quantitative method with survey techniques using the My Class Inventory-Short Form (MCI-SF) instrument which consists of 5 dimensions, namely satisfaction, friction, competitiveness, difficulty and cohesiveness with a total of 25 statements. Based on the research results, the highest average was in the satisfaction dimension at 4.09 and the lowest was in the friction dimension at 1,50. This shows that in the satisfaction dimension, the average student agrees with a pleasant classroom environment. Meanwhile, in the friction dimension, the average student stated that they strongly disagreed that pupils are always fighting with each other. Based on the research carried out, the value of tcount = 13,267, so the value of tcount > ttable. This means that there is an influence between the classroom environment on the learning outcomes of class XI students at SMAN 70 Jakarta with a percentage of the influence of the learning environment of 85,4% which is included in the strong category.
