Abstract

To perform slice thickness calculation automatically using the non-rotational method on the three ladder objects in the AAPM CT Performance Phantom image. Phantom was scanned with a GE Healthcare 128-slice CT scan scanner using slice thicknesses of 0.625 mm, 5.0 mm, and 10.0 mm. The software was developed with a non- rotational method to be able to measure the FWHM value and the mean on the three rungs of the object. In addition, the FWHM of the non-rotational method was compared with the rotational method The FWHM value from automatic measurement for slice thickness is 0.625 mm in three slice variations with non-rotational method 1.68 mm and rotation method 1.61 mm while for slice thickness 5.0 mm on non-rotation method is 6.51 mm, rotation method is 6.68 mm. , and for a slice thickness of 10.0 mm for the non-rotational method 9.58 mm and the rotational method 9.75 mm. The results of the non-rotational method were slightly lower (i.e. 1,74%) than the results of the rotational method for each nominal slice thickness, except for the smallest slicethickness The automatic slice thickness measurement algorithm on AAPM CT Performance Phantom has been improved using a non-rotational method. The improved algorithm can overcome the widening problem that occurred in the previous method due to object rotation.

Abstract

Conceptual understanding is a basic skill that students need to have in learning. This has encouraged many researchers to implement strategies in learning to improve students' understanding of kinematics material. This article conducts a comprehensive review of 22 Scopus indexed journals to answer research questions related to What strategies are used in learning kinematics material and what difficulties do students experience during learning? The method is carried out using the PRISMA stages which consist of four journal mapping processes, namely identification, screening, eligibility, and included in this review. The review results indicate that from 2016 to 2024, various strategies and comparative studies have been implemented in kinematics learning. Most of these strategies effectively enhance students' conceptual understanding. However, there are still some difficulties for students in understanding the concept of kinematics which are still underlined, especially in understanding the interpretation of x-t, v-t, and a-t graphs.

Abstract

This study analyzes the effect of CTL learning model based on ethnoscience on critical thinking skills and science learning outcomes of elementary school students. Initial observations indicate that students' critical thinking skills still need to be improved, especially in articulating their ideas and understanding. With a quantitative approach, data were collected through standardized research instruments and analyzed statistically. The results of the analysis showed a significant difference between the experimental group taught by CTL model based on ethnoscience and the control group. The F count was 83.267 (p <0.05) for simultaneity between the two, 20.075 (p <0.05) for critical thinking, and 168.644 (p <0.05) for learning outcomes. Ethnoscience that connects traditional knowledge with modern science has been proven to play a strategic role in transforming learning. This approach allows students to construct knowledge by connecting academic concepts and cultural experiences, changing the learning model from conventional to constructivist that develops declarative and procedural knowledge. Learning experiences that are linked to cultural contexts create meaningful learning that enhances students' cognitive and metacognitive capacities. Ethnoscience not only bridges local wisdom and scientific knowledge, but also becomes a catalyst for the development of high-level thinking skills.

Abstract

Secondary metabolites are crucial for plant resistance to biotic and abiotic stress. Fertilization with phosphorus (P), magnesium (Mg), and copper (Cu) can enhance secondary metabolite production, supporting plant defense mechanisms. This study evaluated the effects of P, Mg, and Cu fertilization on nutrient absorption and the production of phenolic and flavonoid metabolites in Pendok rice during vegetative and generative phases. A randomized block design with seven nutrient treatments and three replications was applied, involving 21 pots in a greenhouse. P was supplied as Super Phosphate Ca(H2PO4) (SP-36) and Phosphate Rock (PR). Mg and Cu treatments included combinations with and without their addition. Results showed that SP-36 with Mg produced the highest phenolic content during the vegetative phase, significantly higher than other treatments with 7.80 mg (GAE).g extract-1. Mg increased phenolic levels, while Mg and P had a significant effect (95% confidence level) on flavonoid and phenolic content during both growth phases. In conclusion, Mg and P fertilization effectively enhanced secondary metabolite production, improving plant resilience through nutrient optimization. These findings emphasize the role of proper nutrient management in boosting secondary metabolite quality in rice cultivation.

Abstract

This research is motivated by the development of LKPD (Student Worksheet) for enhancing critical thinking skills of elementary school students. The LKPD used has not yet captured the students' attention. The LKPD has not been able to improve students' learning motivation because it does not align with their learning styles. LKPD serves as teaching material used by teachers to facilitate the delivery of content and achieve learning objectives. This study aims to develop LKPD and assess its validity using the Inquiry model to improve critical thinking skills in Science education about the conservation of natural resources in the 4th-grade class. The type of research used is research and development (R&D), employing the 4-D model. This model consists of four development stages: define, design, development, and dissemination. Based on the results of the validation of LKPD using the Inquiry model to enhance critical thinking skills, the LKPD is deemed feasible for use. The material aspect validation result was 85.41% (valid), the design aspect validation result was 86.53% (valid), and the language aspect validation result was 94.44% (very valid). Therefore, the LKPD using the Inquiry model to improve critical thinking skills is valid.

Abstract

Students' scientific reasoning ability in physics learning remains a significant challenge. This study aims to evaluate the effectiveness of innovative learning models in improving students' scientific reasoning based on indicators such as control, correlation, probability, deductive hypothesis, and conservation. The method used is systematic literature review with PRISMA framework. The results showed that innovative learning models, such as Problem-Based Learning, Project-Based Learning, and Inquiry-Based Learning, have a positive impact on students' scientific reasoning. However, each model has weaknesses in improving certain indicators, especially probability and deductive hypothesis. Therefore, this study recommends the development of a learning model that integrates an authentic problem-based approach with STEAM and cognitive conflict strategies to improve students' scientific reasoning. This research provides insights for educators and researchers in designing more effective and relevant learning strategies.

Abstract

The learning process will be effective if supported by learning media that is right on target and based on student needs analysis. LEPAS (Student Exploration Sheet) as a learning media is characterized by integrated activities with traditional games as activities. In addition, LEPAS has the advantage that the activities carried out are able to foster student experimentation but use simple experimental materials so that they are easily implemented by students. Experimental science is a very suitable learning method to be applied in science learning. This research uses the RND method by developing LEPAS. The 4D RND model was chosen as the development model. The research subjects were fourth grade students of SD Al Islam Yogyakarta and their class teachers. The results showed that the LEPAS media that had been developed had received validation by experts with the results of the percentage of material validation of 95%, media 90.66%, language 88.33% with a very valid category. Based on the needs analysis, the results show that the developed media is very suitable for grade IV elementary school because this media accommodates the needs of students, especially in science learning which requires experiment-based activities. LEPAS is declared feasible to use as media in Class IV based on the analysis of student needs to accommodate experimental learning.

Abstract

This study explores problem-solving skills in physics education by systematically reviewing literature from articles published between 2015 and 2024. The review adhered to the PRISMA-P guidelines and analyzed 18 relevant studies sourced from the Scopus database. The findings reveal that the majority of research focuses on enhancing students' problem-solving abilities, particularly in terms of improving critical thinking, reasoning, and creativity in physics instruction. The integration of technology into teaching methods also emerged as a prominent trend in supporting the development of these skills. High school students were the most common research subjects, followed by college students, underscoring the importance of fostering problem-solving abilities early in education. Furthermore, the study highlights a predominance of quantitative and mixed-methods approaches, suggesting the need for more research into practical classroom applications. The study recommends further investigation into adaptive learning models and calls for more qualitative research to deepen the understanding of problem-solving skills in physics education.
