Abstract

This study aims to determine the effect of the two-stay two stray cooperative learning model (TSTS) assisted by STEM-based interactive media on critical thinking and student learning outcomes on sensory system material at SMA Negeri 2 Kerinci. This type of research is quasi-experimental research with a randomized control-group posttest-only design. The population of this study came from class XI students of SMA Negeri 2 Kerinci for the 2021/2022 Academic Year. The sampling technique used is a purposive sampling technique, namely that the determination of the sample takes into account certain criteria that have been made for the subject according to the research objectives. Data analysis techniques used the normality test, homogeneity test, and hypothesis test. Based on the research that has been done, it can be concluded that the STEM-based two stay two stray learning model has an effect on critical thinking and student learning outcomes on sensory system material at SMA Negeri 2 Kerinci.

Abstract

One of the factors for improving the quality of education in schools is teaching materials. Based on the results of observations at SMAN 1 Sitiung students have not used e-modules but use electronic teaching materials in the form of pdf files downloaded from the internet and only in the form of writing and a few pictures. Based on the questionnaire results, it is known that students have difficulty understanding the concept of the respiratory system material. This causes low student learning outcomes as evidenced by the daily test scores that are still below the minimum completeness criteria. So, it takes teaching materials that can help in visualizing the subject matter. This type of research is Plomp model development research which consists of three stages: the initial investigation stage, the development or prototyping stage, and the assessment stage. The research subjects were class XI students at SMAN 1 Sitiung for the 2022-2023 academic year. Validation results by the validator on e-module-based Science Technology Engineering and Mathematics (STEM) show an average grade 88.05% (very valid). Practical results by Biology teachers showed an average score of 87.50% (very practical) and 88.28% students (very practical). Effectiveness test data has effectiveness with very effective criteria in terms of cognitive competency assessment with an average of 83.59, affective with an average of 84.24, and psychomotor with an average of 81.08

Abstract

Bromelain enzyme is one type of protease enzyme that has the ability to hydrolyze protein peptide bonds into amino acids. Bromelain enzyme can be found in pineapple (Ananas comosus) which consists of 95% cysteine protease mixture. Bromelain is often used by athletes to treat physical injuries or minor wounds. In obtaining the bromelain enzyme found in pineapple, an isolation process is required, namely by extracting it extracellularly. The method in this study does not go through the cell breakdown process so that it is easier to separate from other impurities and does not mix with other cell materials. This study aims to develop an innovative method in the production of bromelain enzyme using pineapple and honey as raw materials and to evaluate the organoleptic properties, pH, and the presence of lactic acid bacteria. This study is a descriptive study presented in the form of graphs and images. From the research that has been done, it can be concluded that the manufacture of bromelain enzyme using pineapple and honey has succeeded in producing a product that has an organoleptic value of liking (60%), pH 3 (acid) with the number of lactic acid bacteria 2.43 cells/ml.

Abstract

The application of the flipped classroom learning model with an ethnoscience approach trains students to learn independently in developing and sharpening critical thinking skills. The aim of the research is to determine the effect of the flipped classroom learning model with an ethnoscience approach on students' critical thinking abilities. This type of research is a quasi-experiment with a non-equivalent control group design. The sample used consisted of two classes, one class was designated as the experimental class and one class as the control class. The purposive sampling method was used to collect samples. The results of hypothesis testing using the t test show that t count is greater than table at a significance level of 0.05, which indicates that the hypothesis H0 is rejected. Thus, the flipped classroom learning model with an ethnoscience approach influences students' critical thinking abilities.
