Abstract

Acoustic materials such as plastic carpet, gypsum board, styrofoam and plywood can be used to reduce sound intensity. Nevertheless, the existing research has generally focused on single-ingredient studies. In this research, the optimum thickness of each material will be sought based on its efficiency in reducing the sound intensity level. Besides that, the efficiency of various types of materials will also be tested for reducing the level of sound intensity. In this study, a resonator tube was used in making measurements. Acoustic materials used as test materials, both single materials and combined materials, can be placed in the resonator tube. The distance between the sound source and the detector is 30 cm, with the position of the detector right behind the acoustic material. Tests on a single material show that the measured sound intensity level decreases in proportion to the thickness of the acoustic material, with styrofoam has the lowest efficiency. Meanwhile, the combined material that combines plastic carpet material at a frequency of 2000 Hz has an efficiency value that tends to be higher than the combination of materials without carpet with efficiency >30%. However, at a frequency of 1500 Hz, all combined materials have efficiency values that are not significantly different. All models of material combinations are proven to be able to reduce sound intensity levels compared to single materials. Thus, it can be concluded that the combined material has the potential as an efficient acoustic material.

Abstract

Mathematics learning does not only focus on students' mastery of numbers, but also functions significantly in developing the ability to solve problems holistically. This skill is not something that is taught separately, but is integrated into the entire educational process, offering a real context so that mathematical concepts and abilities can be understood and applied. One approach that is highly recommended to achieve this is Problem Based Learning (PBL). This method has been proven effective in improving students' critical thinking skills through exploration and solving relevant problems, allowing students' knowledge to grow in a constructive way. The low achievement in problem-solving competency in Indonesia is a strong reason to apply PBL in mathematics teaching. This study aims to analyze the literature on the application of PBL to improve students' problem-solving abilities. Data were collected and analyzed from relevant journals, and testing and comparison of results were carried out to identify patterns and results from previous studies. In addition, this study also applies a bibliometric approach to explore publication trends, keywords, and the development of themes related to PBL in mathematics education. The analysis was carried out using VOSviewer software to map the relationship between topics and the progress of PBL research themes in the world of mathematics education.

Abstract

Discovery Learning (DL) is increasingly being applied in mathematics learning, but in-depth studies are still needed to assess the extent to which this method is effective in improving students' abilities in solving mathematical problems, as well as analyzing various existing research regarding the impact of DL models on students' problem-solving abilities. This research aims to analyze various existing research results regarding the influence of DL models on students' problem-solving abilities. This study is very important to provide strong evidence about the effectiveness of DL, so that it can help educators make evidence-based decisions in the mathematics learning process. For its methodology, this research uses quantitative meta-analysis by conducting a systematic review of 12 research articles published between 2017 and 2024, and calculating the effect size. The results of the meta-analysis show that the DL model has a significant influence on mathematical problem solving abilities (KPMM), with an effect size reaching 2.569, which shows a large impact in improving this competency. This research contributes to strengthening empirical evidence regarding the effectiveness of DL in mathematics education, especially in terms of developing problem-solving abilities. These findings suggest that educators should consider integrating the DL model in mathematics teaching to improve students' problem-solving abilities.

Abstract

The purpose of this study is to examine the development of scientific publications related to the use of the Inquiry Based Learning (IBL) model in improving students' mathematical critical thinking skills from 2015 to 2025. This research uses a bibliometric analysis approach with a descriptive approach, where data is collected through searches on Google Scholar and analyzed using the Publish or Perish and VOSviewer applications to identify publication trends, researcher collaboration, and mapping of main topics. From a total of 200 initial documents, 16 articles met the criteria and were analyzed further. The results showed a fluctuating trend in the publication of IBL studies on MVC, with peaks of attention occurring in 2020 and 2022. Network visualization and keyword density show that IBL and MHS topics continue to be an important focus, but face implementation challenges that require further attention. This research is expected to be a reference in designing effective learning strategies to improve critical thinking skills.

Abstract

This study aims to analyze the trends and development of research related to the use of Geogebra in improving the understanding of the concept of revival with a bibliometric approach. Data was collected from the Google Scholar database using the Publish or Perish (PoP) application in the 2020-2025 time span. The initial identification results found 393 documents, which were then filtered to obtain 11 documents worthy of analysis. The analysis was conducted with the help of VOSviewer software to map keywords, annual trends, and research topic density. The results showed that the number of publications increased significantly since 2021, with peaks in 2022 and 2023. Network, overlay, and density visualizations show that the topic of Geogebra usage is growing and diversifying, with a focus on interactive learning models, student abilities, and visual understanding of the concept of congruence. This research makes an important contribution to literature mapping and opens up opportunities for further research in the field of mathematics education technology.

Abstract

This study aims to analyze occupational safety in the smoked fish production process through the Job Safety Analysis (JSA) approach in two groups of micro, small, and medium business actors, namely those managed by the Suku Anak Dalam community and those managed by the general public. The research method used is descriptive qualitative with a field observation approach and in-depth interviews to identify potential hazards and preventive measures taken at each stage of work. The results of the study indicate that in business units managed by the Suku Anak Dalam community, most work stages have the potential to cause hazards, but are not accompanied by adequate preventive measures. In contrast, in business units of the general public, several basic control measures have been implemented, such as the use of aids, gloves, masks, and protective shoes. This difference indicates a gap in the implementation of occupational safety due to factors of knowledge, culture, and access to information. This study concludes that a culture-based and educational occupational safety approach is needed to increase awareness and prevent work accidents, especially in remote indigenous communities
