Abstract

This study aims to measure the practicality of science process skills-based electronic student worksheet in the Biology and Environmental Concepts course of a Primary School Teacher Education Program at the University of Jambi. In this study, practicality refers to students' perceptions of ease of use, clarity of language, attractiveness of appearance, practicality in learning, practicality of science process skills-based activities, and efficiency of use. This study uses a quantitative descriptive approach involving 27 primary school education students as respondents. The research instrument is a questionnaire on the practicality of the electronic student worksheet consisting of 12 statements and analyzed using the Rasch Model with the help of Winsteps software. The Rating Scale Model was used because all items employed the same five-point response categories. The analysis was carried out to obtain the person and item reliability values, separation index, item suitability to the model, and mapping of respondent abilities and item difficulty levels. The results of the analysis show that the person reliability value is 0.82 (real) and 0.85 (model), with a Cronbach Alpha value of 0.93 which indicates the consistency of student responses in the very high category. The low item separation indicated limited spread of item difficulty and was interpreted as preliminary evidence of positive but homogeneous practicality perceptions rather than as definitive proof of broad usability. The person separation value of 2.14 (real) and 2.35 (model) indicates that the instrument is able to group respondents into three levels of practicality perception. All statement items were found to fit the Rasch Model with Infit and Outfit Mean Square (MNSQ) values ranging from 0.5 to 1.5. Wright mapping showed that the item difficulty level ranged from -0.62 to 1.10 logit and was below the average respondent's ability (mean person measure = 2.62 logit), indicating that the electronic student worksheet was generally easy to use and understand by students. Thus, the findings provide preliminary, context-bound evidence that the science process skills-based electronic student worksheet is practical for the sampled cohort and can be refined before wider implementation.

Abstract

Climate change is an increasingly significant concern due to rising sea levels and extreme weather events. This phenomenon has made specific regions uninhabitable or unsuitable for agriculture. In addition, promoting climate change literacy is one of the key factors in addressing the posed challenges. Therefore, this research aimed to analyze the implementation of Research-Based Learning with Science, Technology, Engineering, and Mathematics (RBL-STEM) materials to promote students' climate change literacy, using a mixed-methods design. This research employed a mixed-methods design. Quantitative methods were used to analyze climate change literacy, while qualitative methods examined learning activities and phase portraits under the implementation of the materials. The two classes used comprised a control class of 40 students and an experimental class of 42 students. Meanwhile, the instruments used were interviews, questionnaires, and students’ climate change literacy tests. The results showed that there were differences between the control and experimental classes using an independent sample t-test with a sig value (2-tailed) of 0.0048 (<0.05). In the context of this research, the implementation of the materials promoted students’ climate change literacy in recycling plastic waste into ecobricks.

Abstract

The rapid detection of emergency vehicle sirens is critical for enhancing road safety and traffic management. This study proposes an automated classification system for ambulance sirens using a Convolutional Neural Network (CNN). The method utilizes Mel-Frequency Cepstral Coefficients (MFCC) to transform audio signals into 2D feature maps, allowing the model to capture distinct spectral and temporal patterns. The dataset was preprocessed using a stratified split to ensure balanced class distribution and prevent data leakage. Experimental results demonstrate that the CNN model achieves a high performance with an accuracy of 0.95, significantly outperforming baseline models such as Multi-Layer Perceptron (MLP) and XGBoost. Detailed evaluation through a confusion matrix indicates a consistent precision, recall, and F1-score of 0.95, proving the model’s robustness in distinguishing sirens from complex urban noise. The implementation of the Adam optimizer and early stopping mechanism ensured stable convergence and prevented overfitting. These findings suggest that the proposed CNN-MFCC framework provides a reliable solution for real-time emergency signal detection, offering a substantial contribution to intelligent transportation systems.

Abstract

This study aims to assess the effectiveness of contextual learning media in improving the conceptual understanding and independent learning of 5th-grade students at Keleyan 2 Socah Elementary School. The saturation sampling method was used to ensure that the entire population of 50 students from classes V-A and V-B was included in the research sample. A quantitative approach using an evaluative design was employed, including tools such as concept comprehension tests and learning independence questionnaires. Data analysis was conducted using IBM SPSS software, including validity testing, reliability testing, homogeneity testing, normality testing, and independent samples t-tests for hypothesis evaluation. The analysis findings show significant differences in the concept understanding variable, with a significance value of 0.002, which is less than 0.05, and in the learning independence variable, with a significance value of 0.000, also less than 0.05. The results confirm that contextual learning media positively influences elementary school students' understanding of mathematical ideas and improves their self-directed learning abilities.

Abstract

This study examines the integration of local ecological knowledge into bird-of-paradise conservation strategies in the Tabi and Saireri customary areas, Papua, with a field focus in the East Sentani (Tabi) and South Yapen (Saireri) districts. Using qualitative methods with an ethnographic approach and case studies, this study aims to understand how indigenous communities manage and conserve birds-of-paradise through local wisdom practices embedded in their socio-cultural systems. Data were collected through in-depth interviews, participant observation, and focus group discussions with 32 participants consisting of traditional elders, traditional hunters, female forest managers, and village officials involved in customary-based conservation practices. Data analysis was conducted thematically to identify local values, rules, and institutional mechanisms that support conservation. The results revealed four main themes: (1) the establishment of taboo zones and sacred forests as habitat protection spaces, (2) seasonal hunting regulations and fishing gear restrictions, (3) ritual governance and customary sanctions to maintain ecological balance, and (4) community oversight mechanisms through customary institutions. The findings indicate that the integration of local knowledge is effective when recognized in formal policies through co-management schemes, strengthening the role of customary institutions, and recognizing customary sanctions in regional conservation regulations. Local knowledge-based strategies not only maintain the habitat and population of birds of paradise but also strengthen the social legitimacy of conservation policies. This study recommends the development of co-management instruments between local governments and indigenous communities as a contextual, inclusive, and sustainable policy framework for bird-of-paradise conservation in the Tabi and Saireri customary territories.

Abstract

This study aims to develop a mathematics teaching module based on the ethnomathematics of the Sasak tribe, incorporating deep learning principles to enhance students' understanding of geometry. The research was conducted at MTs Muhammadiyah Selong with the involvement of 17 seventh-grade students. The module development followed the 4D model, which includes the stages of Define, Design, Develop, and Disseminate. The Define stage focused on gathering information, setting learning objectives, determining the topics, and identifying the target audience and content through data collection from observations and interviews. The Design stage involved selecting the module design, format, and structure. The Develop stage included the creation and editing of the module, followed by expert validation for content and media, and a pilot test to assess its functionality. The Disseminate stage included distributing the validated module to the students for further implementation. The results of the module validation from both media and content experts showed that the module was highly valid, with an average score of 82.69% for content and 82% for media design. A small-scale trial with teachers and students indicated that the module was very practical, with an average score of 84% from teachers and 81% from students. The effectiveness of the module was tested using a paired sample T-test, which revealed a significant improvement in students' geometric understanding (p < 0.05). Furthermore, the N-gain analysis showed a moderate improvement in the students' performance. This research highlights the potential of integrating deep learning principles with local ethnomathematics in creating a meaningful, contextual, and effective learning experience for students, particularly in the understanding of geometry.

Abstract

This study examines patterns of advanced mathematical thinking (AMT) in learning function limits through students’ cognitive styles and APOS-based scaffolding. Although previous studies have investigated APOS theory and cognitive styles separately, limited research has explored how both interact in the development of AMT within calculus learning, particularly in the concept of function limits. Adopting a qualitative case study design, data were generated through semi-structured interviews, classroom observations, and document analysis involving 24 mathematics education students at Universitas Islam An Nur Lampung. In this study, cognitive style refers to field-dependent and field-independent learning tendencies, while AMT is represented through indicators of reasoning, abstraction, representation, proof, and problem posing. The analysis employed thematic coding to identify patterns emerging from students’ learning experiences during APOS-based scaffolding activities. The findings reveal three interrelated themes. First, students with field-independent cognitive styles demonstrated more flexible and self-directed reasoning when solving limit problems, whereas field-dependent students relied more on guided explanations, visual representations, and collaborative support. Second, the APOS-based scaffolding sequence of action, process, object, and schema illustrated students’ gradual movement from procedural manipulation toward conceptual interpretation of limits. Third, collaborative scaffolding activities created opportunities for peer explanation and collective meaning-making that supported mathematical generalization. Across the AMT indicators, reasoning obtained the highest average score (3.6), while proof showed the lowest average score (2.9), indicating that students experienced greater difficulty in constructing formal mathematical justification. These findings indicate patterns showing that students’ advanced mathematical thinking emerged through the interaction between individual cognitive tendencies and instructional scaffolding rather than through isolated instructional techniques alone. The study highlights the importance of aligning scaffolding practices with learners’ cognitive characteristics in calculus instruction and contributes qualitative insights into the development of AMT in higher mathematics learning.

Abstract

Motile Aeromonad Septicemia (MAS) is a disease affecting freshwater fish and is caused by Aeromonas hydrophila. The control of MAS commonly relies on synthetic drugs and antibiotics. This study aimed to evaluate the biopotential of rambusa (Passiflora foetida L.) fruit extract as an antibacterial agent against A. hydrophila. The antibacterial activity was assessed using the disc diffusion and Minimum Inhibitory Concentration (MIC) methods, supported by qualitative and quantitative phytochemical analyses. The results showed that rambusa fruit extract produced inhibition zones against A. hydrophila. The inhibition zone of the aqueous extract after 24 hours of incubation was 3.25 mm, while the methanolic extract produced an inhibition zone of 11.42 mm. These findings indicate that rambusa fruit extract prepared using both distilled water and methanol as solvents can inhibit the growth of A. hydrophila. Qualitative phytochemical screening of the aqueous extract revealed the presence of flavonoids, alkaloids, tannins, saponins, and hydroquinones based on the 10% KOH test. Quantitative analysis also detected flavonoids, alkaloids, tannins, saponins, steroids, phenolics, anthocyanins, and triterpenoids. The MIC test showed that concentrations of 100–600 mg/L were effective in inhibiting the growth of A. hydrophila within the weak inhibition category, while concentrations of 700–900 ppm showed higher inhibitory activity. These results suggest that rambusa fruit extract has potential as a natural antibacterial agent against A. hydrophila.

Abstract

This study was motivated by the low level of creativity among elementary school students in mathematics learning, which is still largely dominated by conventional methods and rote memorization. The aim of this study was to develop digital mathematics teaching materials based on the STEAM approach (Science, Technology, Engineering, Arts, and Mathematics) to enhance students' creativity. This study employed a Research and Development (R&D) design using the ADDIE model, which consists of Analysis, Design, Development, Implementation, and Evaluation. The analysis stage was conducted through classroom observations and interviews to identify learning needs. The developed product was validated by education experts, subject-matter experts, and STEAM experts, and was subsequently tested for practicality by teachers and students, as well as for effectiveness through the implementation of STEAM-based digital mathematics teaching materials at Lab School SD Unismuh Makassar. The results of the needs analysis indicated a demand for more interactive learning strategies and media that could help students understand concepts visually and contextually. The design of STEAM-based digital mathematics teaching materials in elementary schools is not only oriented toward academic outcomes, but also toward shaping students' character, creativity, and 21st-century skills. The evaluation results from the three validators (education expert, subject-matter expert, and STEAM expert) showed an average score of 3.28 or 85.56%, which falls into the very valid category. The practicality test involving teachers and students yielded an average score of 3.3 or 82.5%, which falls within the interval of 70% ≤ P < 85% and is categorized as practical. This indicates that the teaching materials were considered easy to use, clear, and relevant to students' learning needs. The implementation results showed a significant improvement. The analysis demonstrated that STEAM-based digital mathematics teaching materials contributed to an increase in students' creativity. Descriptively, the mean creativity score increased from 2,799 (pretest) to 3,399 (posttest). This improvement was also supported by a class N-gain score of 0.500 (moderate category), indicating a meaningful improvement in learning from an educational perspective. Furthermore, the paired-sample difference test revealed a significant difference between the pretest and posttest results (Sig. 2-tailed = 0.002 < 0.05), confirming that the use of STEAM-based digital teaching materials had a significant effect on improving students' creativity.

Abstract

Chemistry is a subject that students tend to dislike. Student learning outcomes are still low due to the lack of student interest in learning which is caused by the lack of media used for learning both at home and at school. To overcome this deficiency, interesting learning media is needed as a complement to learning resources that students can use anywhere and anytime, one of which is Android-based mobile learning media. The aim of this research is to determine the effectiveness of using Android-based mobile learning chemistry learning media to increase students' interest in learning chemistry on the topic of buffer solutions. This type of research is Quasi Experimental Design in the form of Nonequivalent Control Group Design. The subjects of this research were students of class XI MIPA 1 and XI MIPA 2 at SMAN 3 Mataram, totaling 58 students. Data collection techniques include interviews and questionnaires. The data analysis used was N-gain score analysis as well as normality, homogeneity and t-tests. The research results showed that the N-gain for the experimental class was 0.618 with medium criteria (effective) while the control class obtained 0.299 with low criteria (not effective). Normality and homogeneity tests showed that the N-gain data was normally and homogeneously distributed. The results of the t-test at the 5% significance level were obtained a significance value showing 0,000 < 0,05. These results indicate that the use of mobile learning media is effective in increasing students' interest in learning chemistry on the topic of buffer solutions.
