Abstract

This study aims to determine the ethanol content from banana stem and corn cob residues with variations in treatment and fermentation time using a starter culture to accelerate the fermentation process. The method used was an experimental design with treatment variations and fermentation times of 9, 12, and 15 days. Quantitative data were analyzed by measuring the average ethanol content and volume produced for each treatment and fermentation time, then presented in graphical form. The results showed that the highest ethanol content was obtained in treatment A (100% yeast) with 20% ethanol after 15 days of fermentation. In conclusion, the longer the fermentation time, the higher the ethanol content; however, the effect of fermentation time was not always consistent because ethanol content is influenced by the materials used, fermentation duration, and the condition of microorganisms during the fermentation process. Keywords: Banana Stem Residues, Bioethanol, Corn Cob Residues, Environmentally Friendly Technology

Abstract

This study aimed to enhance biology students’ critical thinking skills through the development of STEM-based instructional materials for the Invertebrate Zoology course. Employing a design and development research approach using the ADDIE model, the study involved needs analysis, module development, expert validation, practicality testing, and effectiveness evaluation. The materials integrated STEM elements including ecological measurement tools, technological media, specimen preparation, and data analysis. Validation by experts yielded a 98% score, indicating high validity. Practicality tests showed increasing student satisfaction across individual (83.47%), small group (85.66%), and full-class trials (94.30%). The effectiveness was assessed using a one-group pretest-posttest design. The Wilcoxon Signed-Rank test revealed a statistically significant improvement in students’ critical thinking skills (p = 0.000). Posttest results showed that 66.67% of students reached the “very good” category and 33.33% were in the “good” category, with a mean score of 84%. Among Ennis' critical thinking indicators, “defining terms” had the highest score (95.24%), while “generalizing from evidence” scored the lowest (72.38%). These findings indicate that STEM-integrated teaching materials can effectively foster students’ higher-order thinking in biology education.
