Abstract

The Merdeka Curriculum provides opportunities for all Indonesian students to explore their talents, one of which is through the National Science Olympiad (OSN). This study aims to analyze student participation and achievement in OSN across regions in Indonesia. This research was conducted using a quantitative approach and cluster random sampling technique. Respondent categories were divided based on student domicile areas: Java and non-Java. The participation and achievement of students in both regions showed that students domiciled in Java Island still dominate participation and achievement in OSN. The study also found that school facilities, costs, and lack of support from teachers and parents are the main obstacles for students outside Java. The impact of OSN is also very beneficial, especially in supporting students' studies and careers, as well as increasing the chances of better educational opportunities in the future. These results provide essential information on equitable improvements in support and access for students and schools in all parts of Indonesia to participate in the OSN.

Abstract

In this modern era, noise has become an increasingly common and significant problem in everyday life, thus requiring the use of sound absorbers to address this noise issue. This research created a sound absorber using coconut husk waste through the impedance tube method. Sound absorbers can be made by utilizing readily available waste materials, such as coconut husk waste. The effectiveness value of the coconut fiber absorption coefficient was tested using the impedance tube. The research method employed was the impedance tube method, with variations ranging from level 1 to level 5 and frequencies of 200 Hz, 400 Hz, 600 Hz, and 800 Hz. The impedance tube lengths used in this study were 50 cm and 100 cm. The highest absorption result at a tube length of 50 cm was found at level 1 with a frequency of 200 Hz. At a tube length of 100 cm, the highest absorption value was observed at level 2 with a frequency of 600 Hz. Based on this research, it was concluded that coconut husk can minimize noise and serve as an effective sound absorber.

Abstract

The increasing demand for paper has significantly impacted the environment due to the heavy reliance on wood as a primary raw material. This study investigates the feasibility of using durian (Durio zibethinus) peels and corn (Zea mays) stalks as alternative raw materials for paper production, focusing on their physical characteristics. The paper pulp was prepared using the soda pulping method with NaOH. Various ratios of durian peels and corn stalks were mixed: 1:0 (A), 0:1 (B), 1:1 (C), 2:1 (D), and 1:2 (E). Results indicated that type D produced the thickest paper, while type A produced the thinnest. The highest grammage was observed in type E, and the lowest in type D. Type C showed the highest absorbency. The tensile and tear indexes were highest in type D and lowest in type C. Type A had the highest mass density, whereas type D had the lowest. The findings suggest that a combination of durian peel and corn stalks exhibits diverse physical properties, indicating their potential use as an alternative to conventional wood-based paper. This approach could reduce the dependency on wood and contribute to environmental conservation.

Abstract

The context of ethnoscience-based learning in the Merdeka curriculum is related to socio-cultural studies. Following up on the uncommon science learning integrated with ethnoscience studies, especially in the socio-cultural realm, a content analysis of textbooks used in schools was conducted. This study aims to determine the potential of junior high school science learning using the Merdeka curriculum integrated into ethnoscience studies in the socio-cultural aspect. The research was conducted using the content analysis method, with the analyzed indicators consisting of 5 parts of values in socio-cultural. The results showed that science learning has great potential to be integrated with ethnoscience studies, considering that the textbooks have been able to present all value indicators in the socio-cultural. All indicators have been contained in the book in each chapter, except for spiritual value incarcerates. The appearance of all indicators in each chapter in the book provides information on the suitability of textbooks with the aim of curriculum. However, spiritual value indicators are still contained in only 2 chapters in the book, so it is necessary to strengthen spiritual values in each chapter in the book. Further research can be done by conducting content analysis with a more diverse number of books, so as to provide a broader picture of textbooks

Abstract

Pre-service teachers play an important role in teaching and influencing future learners. One of the important skills that prospective teachers must have is mathematical ability, so information about pre-service teachers' learning tool preferences in understanding mathematical concepts is crucial. This study aims to identify pre-service teachers' learning tool preferences for understanding mathematical concepts. This study used mixed methods, quantitative and qualitative. Data collection was carried out by distributing questionnaires to 129 prospective teachers from mathematics and science education study programs, as well as elementary school teacher education at Mulawarman University. Quantitative questions used Likert scale-type questions, and qualitative used free-response questions to get an in-depth analysis. The results of this study showed a very weak correlation between learning aid preferences and the understanding of basic math concepts, but it increased considerably when linked to advanced math concepts. In addition, there is a difference in preference between male and female pre-service teachers, where males are more likely to favor tools such as AI or ChatGPT, while females prefer learning videos. This study is expected to provide valuable information for policymakers to provide facilities that support the learning needs of pre-service teachers.
