Abstract

Learning in the environmental physics course is directed at sharpening students' sensitivity to overcoming problems and utilizing the potential that exists in the environment. Waste management is the main focus in environmental physics learning, which in this research is pineapple crown leaf waste which has the potential as activated carbon to be processed into resistors. The purpose of this study was to test the activator and carbonization tool for pineapple crown leaves with the highest inhibition value. This activator is in the form of Wuluh star fruit and Calamansi. The carbonization tools are an infrared stove and a blue flame twister furnace. This research method is in the form of an experiment. This activity research is integrated with the STEAM-2C components. The data analysis technique is in the form of comparing the average resistance values ​​of the pineapple leaf resistor variations. It was found that = 0.067 MΩ; = 0.16 MΩ; = 0.12 MΩ; = 0.14 MΩ. It was concluded that the activator and carbonization tool for pineapple crown leaf with the highest inhibition values ​​were the Calamansi activator and Infrared stove carbonization tool. This research is expected to add insight into producing innovations that are tested experimentally as the implementation of environmental physics learning.

Abstract

The curriculum continues to develop along with the times. The rapid development of technology requires curriculum adjustments. The domain of knowledge is no longer the only core domain of the curriculum. The domains of skills, character, and meta learning play a role in successful learning. A learning model is needed that is able to activate the four curriculum components. One of them is a collaborative problem solving based learning model. How is this model implemented in science learning? Through this re search, the researcher tries to explore the related research results that have been reported in 5 selected journals.

Abstract

This study used a cross sectional design, which focused on the relationship between critical thinking skills and nutrition and health literacy. The research subjects were 102, first year (37 students) and second year (65 students) Culinary Education students. Critical thinking skills level was obtained by providing multiple choice tests, with score grade of 1-4. Nutrition and health literacy level was obtained by providing questionnaires from Nlit and The Newest Vital Sign. The relationship degree was analyzed by using Pearson correlation. Meanwhile, the difference in year of admission and gender were tested using independent sample t-test. The results showed that there was a correlation of r = 0.304 with p = 0.002 for the critical thinking skills and nutrition and health literacy. The critical thinking skills of first year students (65.7 ± 4.5, very high) was not significantly different (p = 0.735) with second year students (66.0 ± 4.1, very high). Nutrition literacy and health of first year students (45.9 ± 9.8, high) were significantly different (p = 0.045) with second year students (49.2 ± 6.5, high). The critical thinking skills of male students was higher (68.5 ±3.4, very high) and not significantly different from that of female students (65.5 ± 4.3, very high). The nutrition and health literacy of male students (68.5 ± 3.4, very high) was higher and significantly different than female students (65.5 ± 4.3, very high).
