Abstract

This study aimed to analyze the profile of senior high school students’ critical and creative thinking skills in Biology learning as part of developing 6C competencies. The method employed was descriptive quantitative research involving 33 students of class XI.10 at SMAN 1 Karanganyar, Kebumen Regency, selected through purposive sampling. Data were collected using essay tests of critical thinking skills based on Ennis’ indicators, creative thinking skills based on Torrance’s indicators, student perception questionnaires, and classroom observations. The data were analyzed descriptively using the mean score of each indicator. The results showed that the average score of students’ critical thinking skills based on the five Ennis indicators was 67.8%, categorized as moderate, while creative thinking skills based on Torrance’s indicators reached 55.56%, categorized as low. Students’ perception questionnaires indicated that both critical and creative thinking skills were in the high category with an average score of 73%. Classroom observation results supported the findings of the essay tests. In conclusion, students’ critical thinking skills in Biology learning are categorized as moderate, while their creative thinking skills are categorized as low.   Keywords: Biology, Creative Thinking, Critical Thinking, Profile, Senior High School Students.

Abstract

The contribution of Saccharomyces cerevisiae is expected to accelerate the fermentation process and enhance the microbial population involved in eco-enzyme production. This study aimed to analyze the potential role of S.cerevisiae in improving eco-enzyme production. A true experimental method was employed using a completely randomized design with four treatments and three replications. The results, based on the average matrix similarity test using the Wilks’ Lambda Test, showed that the significance values for pH, DO, BOD, nitrite, and nitrate were < 0.05. Therefore, H0 was rejected, indicating that varying doses of S.cerevisiae had a significant effect. Furthermore, significant differences were observed among the treatments for each dependent variable. In conclusion, S.cerevisiae contributes to enhancing the overall quality of eco-enzymes by facilitating fermentation and accelerating the decomposition of organic matter.
