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

Sauerkraut is a typical German food made from thinly sliced cabbage. Sauerkraut is a fermeted product that can give a distinctive taste. Sugar is an ingredient that can be added in, that sugar can trigger the growth of lactic acid bacteria. Indonesian people like food with a spicy sensation from chilies, chillies here contain vitamin C which functions as an antioxidant that is good for the body and is able to increase endurance. This study aims to calculate the total lactic acid bacteria contained in sauerkraut with the addition of chilies and sugar. Dilution of 1 ml sample into 9 ml physiological NaCl solution from 10 -1 to 10 -8 dilutions was carried out, then inoculated into MRS Agar using the pour plate method. Incubated in room temperature for 48 hours. The growing colonies of lactic acid bacteria were then observed based on colony morphology and counting the total growing lactic acid bacteria. The results of the research can be concluded that there was an increase in the number of lactic acid bacteria in sauerkraut with the addition of chili and 10% granulated sugar with a bacterial density average is 88.667 x 108 CFU/mL.

Abstract

The purpose of this research is to produce interactive multimedia using Macromedia Flash 8 for class VIII students at SMPN 34 Padang with material on the respiratory system and human excretory system that is valid, practical and effective. The data collection instruments used were interactive multimedia validation sheets by 3 validator lecturers, interactive multimedia practicality questionnaires by science teachers and students, as well as observation sheets on cognitive, affective, psychomotor aspects and learning activities. The results of the validation assessment by the validator of interactive multimedia on material on the human respiratory system and excretory system showed an average value of 82.33% (very valid). The results of the practicality assessment by science teachers showed an average score of 85.51% (very practical) and the results of the practicality assessment by students showed an average score of 91.64% (very practical). The results of the effectiveness test of interactive multimedia using Macromedia Flash 8 from the cognitive, affective, psychomotor and student activity aspects show that interactive multimedia using Macromedia Flash 8 is very effective. Thus, it can be concluded that the interactive multimedia using Macromedia Flash 8 developed is very valid, very practical and very effective.

Abstract

The purpose of this research is to produce an android based ebook in Animal Ecology courses that is valid, practical and effective. This research is research and development using the Plomp model. The results of the validation assessment by the validator of the android-based e-book in the Animal Ecology course showed an average value of 82.33% (very valid). The results of the practicality assessment by lecturers of the Animal Ecology course showed an average value of 81.5% (very practical) and student assessment results obtained an average value of 91.64% (very practical). The results of the effectiveness test of Android-based e-books show that Android-based e-books are very effective. Thus, it can be concluded that the developed Android-based e-book is very valid, very practical, and very effective.

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.

Abstract

This research is motivated by the low level of science literacy among students in Indonesia, including at SMP Negeri 17 Kota Jambi. The study aims to determine the effect of the STEM-based PBL model on the science literacy of seventh-grade students at SMP Negeri 17 Kota Jambi. This type of research is a quasi-experiment with a pre-test post-test control group design. The research sample consisted of two classes: the experimental class (VII C) with 32 students who received the STEM-based PBL model treatment, and the control class (VII E) with 31 students who used the direct instruction model.  The research results science literacy skills improved, with an average pre-test score of 58.5 and a post-test score of 79.75, while the control class increased from 38.32 to 60.38. The N-Gain value for science literacy in the experimental class was 50.83 (moderate category), which was higher than the control class's 38.32. The t-test results show a significance value of 0.037 < 0.05, which means there is a significant difference between the two groups. It can be concluded that the implementation of the STEM-based PBL model is effective in improving students' science literacy skills in science learning.
