Abstract

Partial Differential Equations (PDEs) are widely used in various fields of science, such as physics, engineering, and finance, to model complex phenomena such as heat transfer, fluid dynamics, and wave propagation. However, analytical solutions to PDEs are often difficult or even impossible to obtain, making numerical approaches necessary. This study aims to analyze numerical methods for solving PDEs, with a focus on the finite difference and finite element methods. We compare the accuracy, stability, and computational efficiency of various numerical schemes using MATLAB-based simulations. The results indicate that the finite element method performs better in handling complex geometries, while the finite difference method is more efficient for computations on uniform domains. With the appropriate method selection, numerical approaches can be effectively used to solve various problems modeled by PDEs. This study is expected to provide insights for the development of more accurate and efficient numerical methods in a wide range of scientific and engineering applications.

Abstract

This study aims to determine the effectiveness of applying the Problem-Based Learning (PBL) model in enhancing students' conceptual understanding of physics at SMA Negeri 1 Gunungsari. Problems in physics learning are often related to the low level of conceptual understanding, which results from conventional teaching approaches that lack active student engagement. The PBL model offers a student-centered learning approach, in which students are presented with contextual problems that encourage them to think critically, seek information, and build understanding through discussion and group work. This research employed a quasi-experimental method with a pretest-posttest control group design. The research subjects consisted of two grade XI science classes selected purposively: one class served as the experimental group using the PBL model, while the other class served as the control group with a conventional learning method. The analysis results showed a significant improvement in conceptual understanding in the experimental group compared to the control group. The average posttest score of the experimental group was statistically higher, and the N-Gain value increase demonstrated the effectiveness of PBL in fostering students' conceptual understanding. These findings indicate that the implementation of the PBL model can be an effective alternative learning strategy to improve the quality of physics education at the senior high school level.

Abstract

This study aims to examine the effectiveness of STEM-based learning (Science, Technology, Engineering, and Mathematics) in enhancing students' creativity and critical thinking skills at SMP Negeri 1 Jombang. The background of this research is rooted in the low level of student engagement in conventional learning processes, which tend to emphasize memorization rather than the development of higher-order thinking skills. The research method used was a quasi-experimental design with a pretest-posttest control group. The research sample consisted of two classes: an experimental class that implemented STEM-based learning and a control class that used conventional learning methods. Research instruments included a critical thinking test, creativity observation sheets, and student response questionnaires. Data analysis results showed a significant increase in students’ creativity and critical thinking scores in the experimental class compared to the control class. This improvement was confirmed through statistical testing using the t-test and normalized gain, which indicated a high level of effectiveness in the experimental group. Furthermore, the questionnaire results revealed that students responded positively to the STEM-based learning approach, finding it more engaging, challenging, and relevant to real-life contexts. Therefore, it can be concluded that STEM-based learning is effective in improving the creativity and critical thinking skills of junior high school students. These findings recommend the broader implementation of STEM learning models in the context of Indonesian lower secondary education

Abstract

This study aims to determine the effect of interactive animation media on students’ learning motivation in Physics subjects at SMA Negeri 2 Surabaya. The background of this research is based on the low interest and motivation of students in learning Physics, which is often considered difficult and boring. The use of conventional learning media, which tends to be less interactive, often fails to attract students' attention and interest. Therefore, interactive animation media is expected to be an effective alternative solution to improve learning motivation. The research method used is a quasi-experimental design with a pretest-posttest control group. The research sample consisted of two classes: the experimental class, which used interactive animation media, and the control class, which used conventional lecture methods. The instrument used was a validated and reliability-tested learning motivation questionnaire. The results of the study show that there is a significant difference in learning motivation between students in the experimental class and those in the control class. Students who learned using interactive animation media showed a higher increase in learning motivation compared to those who learned through conventional methods. These findings indicate that the use of interactive animation media can positively contribute to improving students' motivation in learning Physics. Therefore, teachers are encouraged to integrate interactive animation media as part of their classroom teaching strategies.

Abstract

This study aims to develop a mathematics module based on ethnomathematics rooted in local culture as an effort to improve students' numeracy literacy at SMP Negeri 1 Yogyakarta. The background of this research is based on the importance of linking mathematics learning with students’ cultural contexts to foster learning interest and a deeper understanding of concepts. The ethnomathematics approach used in the module development integrates local cultural values—such as batik patterns, traditional games, and regional architectural styles—into mathematics material taught at the junior high school level. The research method employed is Research and Development (R&D) using the 4D development model (Define, Design, Develop, Disseminate). The research subjects were eighth-grade students at SMP Negeri 1 Yogyakarta. Validation results from material and media experts indicated that the developed module is suitable for classroom use. A limited trial also showed an improvement in students’ numeracy literacy skills after using the module. Additionally, students responded positively to content that was connected to their own culture, which encouraged active participation in learning. These findings suggest that integrating ethnomathematics into mathematics instruction not only enhances conceptual understanding but also strengthens students' cultural identity. Therefore, this module can serve as an innovative alternative to improve the quality of mathematics learning in schools.

Abstract

The decline in students' interest in learning Biology has become a recurring issue at the senior high school level, including at SMA Negeri 8 Surabaya. This study aims to analyze the implementation of the scientific approach in Biology instruction as an effort to enhance students' learning interest. The scientific approach emphasizes the processes of observing, questioning, experimenting, reasoning, and communicating, and is expected to create active, creative, and meaningful learning experiences. The research method used is classroom action research (CAR), conducted in two cycles. The research subjects were 11th-grade science students at SMA Negeri 8 Surabaya. Instruments used included observation sheets, learning interest questionnaires, and documentation of students' learning outcomes. The results showed that the implementation of the scientific approach significantly increased students' learning interest, as indicated by improved participation in discussions, persistence in completing assignments, and increased learning interest questionnaire scores from cycle I to cycle II. These findings suggest that the scientific approach is not only curriculum-relevant but also effective in creating a learning environment that fosters students’ emotional and intellectual engagement. Therefore, it is recommended that this approach be widely adopted in Biology instruction as well as in other subjects at the secondary education level.
