Abstract

This study aims to determine the relationship between perception and basic science process skills through the use of the m-module in basic physics practicum II. This research is a quantitative study using correlational design. data collection instruments used in the form of perception questionnaire instruments and observation sheets to measure students' science process skills. This study used a sample of 36 physics students at Universitas Jambi. The results of the study will be analyzed using descriptive statistics and inferential statistics. The results of this study indicate that students give a good perception of the use of the m-module in basic physics practicum II. Flat mirror material is proven from the value of the perception of 63.9% in the good category according to a predetermined range. And the basic science process skills of students are in a good category with a percentage of 50.0%. Pearson correlation results show the number 0.756 and sig 0.05 which is 0.00, this shows that there is a strong relationship between perceptions and students' science process skills in using the m-module. This means that a high perception will result in high science process skills.

Abstract

Evolution is one area on Biology learning that has the most contravention and misconception for many students in various educational regions globally, including Indonesia. This study aimed to identify student's acceptance of the evolutionary theory. The study was conducted using a mixed-method, in which the results of descriptive research were followed by correlational research on the variables studied. Data were collected by using questionnaire and rubric of Measure of Acceptance of The Theory of Evolution (MATE). The results showed that the average MATE score was 65.05, in which the students tended to have a moderate level of the acceptance of the evolutionary theory. The result showed that sex and religious background correlated with students' acceptance of the evolutionary theory, with a contribution of 49.9%. Thus, these results suggest that evolution is a crucial aspect to be considered in teaching evolution, and there must be an effort to overcome the differences in the acceptance of evolutionary theory in students with different gender and educational backgrounds. Three other factors influence student acceptance of the theory of evolution, namely students' misconceptions, beliefs, and understanding of the nature of science. Therefore, identification of students' prior knowledge is needed to determine the factors that influence students' acceptance in a context.

Abstract

The low ability of students to solve problems is in line with the low mastery of science concepts. In this study, Science, Technology, Engineering, and Mathematics (STEM) integrated Project Oriented Problem Based Learning (POPBL) learning models were implemented to improve the mastery of science concepts of junior high school students, especially on the topic of Environmental Pollution. The method used was a mixed-method. The STEM integrated STB learning model design framework consists of 3 stages: Onset Stage, Execution Stage, and Closure Stage. The concept of students is emphasized at the onset stage in the case study dissemination phase. In this phase, students analyze problems based on articles provided by the teacher. The more understanding the material, the more critical students will explore existing issues and find logical solutions to those problems. The results showed that there was a difference between the average pretest and posttest learning outcomes (t=-5,660; df = 53; Sig. (2-tailed) = 0,000). This indicates an increase in junior high school students' science concepts mastery after using the STEM integrated POPBL Learning Model. Improving students' mastery of concepts using a STEM integrated POPBL learning model is still in the low category with n-gain = 0.17. Although still in the low category, the POPBL learning model with the STEM approach can be optimized to improve students' mastery of concepts and skills on other science topics.

Abstract

Xylanase can be used as an alternative material in the pulp bleaching process to reduce the use of chemicals in the paper industry. Bacillus subtilis is a type of bacteria that can produce xylanase. Xylanase characterization is needed to determine the maximum activity that will be used in the pulp bleaching process. This study aims to determine the xylanase characterization of Bacillus subtilis in terms of optimal pH, optimal temperature, carbon source, and optimal nitrogen source. The research material used was a pure culture of Bacillus subtilis bacteria obtained from the Biochemistry Laboratory of the Department of Chemistry, Faculty of Mathematics and Natural Sciences, Brawijaya University. The characterization of the xylanase enzyme was carried out using the RAL method. The results of characterization of the determination of pH, temperature, carbon source, and nitrogen xylanase source from Bacillus subtilis showed that the optimum conditions for xylanase were at pH 7 with a maximum activity of 5.085 U / mL; the optimum temperature at 40oC with activity 8.017 U/mL; maximum carbon source at a concentration of 15% (b/v) with activity 7.517 U/mL; and the optimum source of nitrogen with a concentration of 0.17% (b/v) with an activity of 4.815 U/mL.

Abstract

The Light brick is an engineered product developed from the usual brick with the addition of mixed materials. Brick is one type of composite material. Many people choose to use natural fiber-reinforced composites to replace synthetic ones and composite materials engineering development. So in the technology of brick-making, natural fibers are currently used as a choice as additional material mixed to produce light bricks. Additional materials often used in light bricks include fly ash, sawdust, coconut husks, rice husks, etc. This study used corn husk waste as additional material in the light bricks making. The addition of corn husk powder can affect the mechanical properties of brick. It is shown by the more significant the percentage of corn husk powder added, the smaller the density and compressive test value of the brick produced. Meanwhile, the greater the porosity value is. The decrease in density level and compressive test value will undoubtedly affect the brick's mechanical and physical properties. The reduction in density level and mechanical properties of the brickwork can be minimized by applying an outer layer in the form of cement mortar of the products.

Abstract

This study aims to reveal the impact of distance learning during the Covid-19 pandemic on Science Technology Engineering and Math (STEM) competence, productivity, and students' character. This research uses mixed methods. The questionnaire instrument consists of STEM components, Learning Products, and character profiles obtained from Elementary School/Madrasah Ibtidaiyah, Junior High Schools, and Senior High Schools in Jakarta and Bandung. Furthermore, the data were analyzed, and it was concluded that the performance of all the variables studied had varying degrees. Besides, STEM literacy skills are closely related to learning productivity and character building of students at all levels of education. Therefore, distance learning after the Covid-19 pandemic needs to be planned well and considers the level of STEM literacy and character content clarity.

Abstract

This research is aimed to determine the students’ achievement and critical thinking on the digestion system topic. This study was conducted using a quasi-experiment with a control group pre-test and post-test design. Furthermore, the samples were chosen using the purposive sampling technique. The instrument consisted of 20 multiple-choice tests. Findings indicate that the average student achievement is 16.71 in the experiment and 12.92 in the control class. The t-test also can be known as t-count t-table (1.71 1.68), which means a significant difference between experiment average and control average. Based on the test result in the experiment class, it can be assumed that there is an enhancement of the average percentage of students' critical thinking from 63% to 84%. Thus, it can be concluded that inquiry learning model can increase the students’ achievement and critical thinking.
