Knowledge continues to evolve, requiring teachers to innovate, particularly in implementing the Kurikulum Merdeka (Independent Curriculum). Field observations indicate that many schools still struggle with its implementation, as they must tailor learning to students' individual characteristics. SMPN 03 Lebong in Bengkulu Province is one such school facing these challenges. Given these issues, an alternative solution is needed to support the independent implementation of the Kurikulum Merdeka. One possible approach is to provide training for teachers at SMPN 03 Lebong on designing learning activities and practical worksheets based on the Prediction, Observation, and Explanation (POE) model. This training follows the I-CARE design, which consists of five stages: Introduction, Connection, Application, Reflection, and Extension. As a result, teachers successfully developed six learning designs and practical guides based on the POE model, utilizing available tools and materials from their surroundings. This initiative enhances student-centered learning, aligning with the objectives of the Kurikulum Merdeka.

This study aims to determine the effect of providing a combination of snails and coconut dregs as feed on the growth and protein content of Black soldier Fly (BSF) maggots. The method used is an experiment with a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments consist of: P1 (100% snails), P2 (75% snails: 25% coconut dregs), P3 (50%: 50%), P4 (25%: 75%), and P5 (100% coconut dregs). Maggot maintenance was carried out for 14 days with feeding carried out every 2 days in the morning at 10:00. The research data observed included Weight, Thickness, Length which were analyzed statistically using the ANOVA test and the test was continued with the Least Significant Difference (LSD) test, and the Kruskal wallis test if the data was not normal, temperature and humidity, Feed consumption, Specific growth rate (SGR), Waste reduction index (WRI), and Protein content and water content were analyzed using the automatic kjeldahl test. The results of the study showed that the provision of snail and coconut dregs feed had a very significant effect on the growth of maggots (P <0.05) both in weight and thickness, but had no significant effect (P>0.05) on the growth of maggot length. Treatment P1 (100% snail) gave the best results with an average weight of 0.09 g, a length of 13.4 mm, and the highest protein content of 27.49%. Treatment P5 (100% coconut dregs) showed the lowest results in all main parameters. It was concluded that snail feed was more optimal in supporting the growth and protein content of BSF maggots. The high animal protein content and soft texture are the main reasons, which show the potential of snails as a highly nutritious alternative feed for BSF maggot cultivation.

The bark of the traditional plant, Archidendron bubalinum, known locally as kabau, exhibits promising qualities as a natural antibacterial agent. This research was conducted with two main objectives: (1) to evaluate the antibacterial efficacy of kabau fruit peel extract against two common pathogenic bacteria, Staphylococcus aureus and Escherichia coli, and (2) to design, validate, and assess the effectiveness of a research-based Microbiology E-Module in fostering students' critical analytical skills. The antibacterial capacity was tested using the paper disc diffusion method across a range of extract concentrations (5%, 10%, 20%, 40%, and 80%), using both pure water (aquades) and 2% dimethyl sulfoxide as carriers. Statistical analysis (one-way ANOVA, p = 0.020 < 0.05) indicated a notable difference in the zone of inhibition diameter across the various concentrations. The most potent antibacterial effect was observed at the 80% concentration with the aquades solvent, yielding inhibition zones of 3.97 mm against S. aureus and 8.42 mm against E. coli. These empirical results served as the core content for the innovative E-Module. The developed E-Module attained a high level of validity, achieving a CVR score of 1.00 from 5 expert validators, thus confirming its readiness for use. Subsequent evaluation during instructional application revealed a marked elevation in students' critical thinking abilities. Students in the Biology Department at FMIPA, Universitas Bengkulu, showed an initial mean pre-test score of 41.67, which surged to 88.00 in the post-test. This change resulted in an N-gain score of 0.79, positioning the improvement in the "high" category. Therefore, A. bubalinum extract is confirmed to hold antibacterial potential, and the E-Module is proven to be an effective educational tool for enhancing students' critical thinking competence.
