Abstract

The universe is a space containing large amounts of both organic and inorganic carbon that has the potential to encourage heterotrophs on habitable planets. Meteorites are materials that can transport carbon from outer space to the planet's surface. Meteorites bombarded the Earth's surface during the early days of evolution and proliferation of life, potentially providing a source of abiotic organic carbon to support early life. This study aims to analyze research methods used in detecting the use of space organic carbon, analyze research results related to the role of space organic carbon, and provide further understanding to the researchers associated with organic carbon from space and its potential in human life on Earth. This study uses a systematic review method using 15 sources of information from national and international news and journal articles related to space organic carbon and its potential. This study showed that extraterrestrial organic carbon produces a source of carbon that is beneficial for microorganisms to integrate into their proteins. Combining inverse stable isotope labeling and infrared spectroscopy shows that organic carbon from Aguas Zarcas carbon chondrite can be harnessed for cell growth. Previous discoveries have also shown that aerobic microbial communities have potential in human space settlement plans to access and research carbonaceous asteroid material.

Abstract

21st-century education requires students to address various problems in daily life through problem-solving skills. However, students’ problem-solving skills in Indonesia are relatively below the average score of the Organization for Economic Cooperation and Development (OECD). Integrating local wisdom values into the learning process and applying learning models that present real-world problems, such as the Problem-Based Learning model, can actively engage students in the process of solving these problems. This study aims to describe the results of improvements in problem-solving skills, the implementation of learning, and student responses following the implementation of a Problem-Based Learning model based on local wisdom to enhance the problem-solving skills of junior high school students. The research method used was a quantitative approach with a pre-experimental design. Data collection techniques included problem-solving ability tests (pretest and posttest), observations of instructional implementation, and response questionnaires. The implementation of the Problem-Based Learning model has a significant impact on improving the problem-solving skills of junior high school students, as indicated by an effect size of 0.875221 classified as very large and an average N-Gain score of 0.6 classified as moderate. It can be concluded that the implementation of a Problem-Based Learning model based on local wisdom can improve the problem-solving skills of junior high school students.
