ANALYSIS OF STUDENTS' CRITICAL THINKING SKILLS ON THE TOPIC OF LIVING ORGANISMS CLASSIFICATION THROUGH THE ACTIVE LEARNING METHOD Abstract This study aims to analyze the critical thinking skills of seventh-grade students at SMP Negeri 12 Tarakan on living organisms classification topics by implementing the active learning method. Critical thinking is one of the essential 21st-century skills that should be nurtured in the learning process, particularly in science education. The Active Leaming method was chosen because it allows students to be directly involved in experiencing, analyzing, and drawing conclusions about the concepts they study through hands-on learning This research employed a descriptive design with a quantitative approach. The study subjects were students of classes VII.1 and VII.2 at SMP Negeri 12 Tarakan in the 2024/2025 academic year. Data collection techniques were through observations, interviews, and open-ended test questions designed to assess various indicators of critical thinking skills, including interpretation, analysis, evaluation, inference, explanation, and self-regulation The findings revealed that students' critical thinking skills fall into the good to very good category, with an average indicator achievement rate of 82.3%. The use of active learning methods has proven effective in increasing students' active participation and supporting the development of critical thinking skills, especially in understanding the material on the classification of living things. This study recommends the application of active learning methods consistently in order to create a fun and meaningful learning atmosphere.

Viterna merupakan suplemen pakan ternak yang berperan untuk meningkatkan nafsu makan dan daya tahan tubuh, memacu enzim-enzim pencernaan serta mempercepat pertumbuhan ikan. Penelitian ini bertujuan untuk mengetahui pengaruh pengkayaan tubifex sp. dengan viterna dan ekstrak daun karamunting pada kelangsungan hidup dan pertumbuhan ikan cupang. Metode penelitian ini menggunakan metode rancangan acak lengkap dengan 4 perlakukan dan 3 ulangan. Perlakuan yang diujicobakan adalah pemberian Tubifex sp tanpa viterna dan ekstrak (kontrol), P1= Pemberian Tubifex sp. yang diperkaya viterna sebanyak 10ml + ekstrak dengan konsentrasi 250 ppm, P2= pemberian Tubifex sp yang diperkaya viterna sebanyak 15ml dan ekstrak dengan konsentrasi 250 ppm, dan perlakuan P3 yaitu pemberian Tubifex sp yang diperkaya viterna sebanyak 20ml + ekstrak dengan konsentrasi 250 ppm. Berdasarkan hasil penelitian ini menunjukan bahwa perlakuan pemberian Tubifex sp. yang diperkaya viterna sebanyak 15ml + ekstrak dengan konsentrasi 250 ppm menunjukan hasil yang lebih baik dibandingkan dengan perlakuan lainnya. Uji statistic menunjukkan beda nyata pada pertumbuhan panjang dan berat mutlak serta SGR (Specific Growth Rate) pada perlakuan pengkayaan cacing sutera menggunakan viterna dan ekstrak daun karamunting pada pertumbuhan ikan cupang (Betta splendens) dibandingkan perlakuan kontrol. Data pengukuran kualitas air yaitu suhu 27-280C, nilai pH 6-7 dan nilai amoniak 2,55 mg/l, menunjukkan masih dalam ambang normal. Berdasarkan hasil penelitian maka dapat disimpulkan bahwa penambahan Tubifex sp dan ekstrak karamunting dapat meningkatkan pertumbuhan ikan cupang (Betta splendens).
