Abstract

This study aims to improve the professional competence of Mathematics teachers in the Teacher Professional Program (PPG) through the application of the Technological Pedagogical Content Knowledge (TPACK) model assisted by Microsoft Mathematics. This research is a classroom action research (CAR) conducted in two cycles. Each cycle consisted of planning, action, observation, and reflection stages. The subjects of this study were 16 in-service PPG participants who are mathematics teachers, selected using purposive sampling technique. Data were collected through teacher professional competence tests and teacher activity observation sheets. Data analysis was performed quantitatively using descriptive statistics and qualitatively using interactive analysis techniques. The results showed that in Cycle I, the completion rate of the teacher professional competence test only reached 50% (8 out of 16 teachers passed) with a percentage of teacher activity observation of 62.5%, which had not met the success indicator (≥80%). After reflection and improvement in Cycle II, the completion rate of the teacher professional competence test increased to 81.25% (13 out of 16 teachers passed) with the percentage of teacher activity observation reaching 83.62%. The improvement in professional competence from Cycle I to Cycle II was 31.25%, while the improvement in teacher activity was 21.12%. These results indicate that the TPACK model assisted by Microsoft Mathematics is effective in improving teachers' understanding of the material, pedagogical abilities, and the integration of technology in mathematics learning. The Technological Pedagogical Content Knowledge (TPACK) model assisted by Microsoft Mathematics has proven to be effective and successful in improving the professional competence of Mathematics teachers in the Teacher Professional Program (PPG). The application of this model is recommended as an alternative strategy for sustainable professional development for mathematics teachers.

Abstract

Microplastics persist in aquatic systems and are difficult to remove using conventional filtration methods, prompting the development of low-cost, bio-based alternatives. This study presents a proof-of-concept chitosan filter derived from shrimp-shell waste, evaluated as a membrane sheet and as a coating on cellulose filter papers. FTIR confirmed chitosan formation, showing characteristic –OH/–NH stretching (~3450 cm⁻¹), amide I (~1650 cm⁻¹), amide II (~1570 cm⁻¹), and polysaccharide fingerprint peaks (1200–1000 cm⁻¹). Filtration experiments used a fixed 50 mL mixed-microplastic suspension processed under vacuum through five media: chitosan membrane, coffee filter paper, Whatman No. 42, and their chitosan-coated variants. Filtration time was recorded to derive the apparent filtration rate, and retained residues were assessed by visual inspection, stereomicroscopy, and morphometric size measurements in Fiji (particle size range reported as projected digital measurements). Coffee-based media exhibited the highest throughput (>50 mL/min), the chitosan membrane showed intermediate throughput (10 mL/min), and Whatman-based media were the slowest (7.14 mL/min). Chitosan-containing media displayed localized deposition and broader retained size ranges (up to 3.5 µm) compared with uncoated cellulose. Overall, the results support a waste-to-resource chitosan filtration approach that adds surface-mediated retention alongside passive sieving, with promising potential for application in laboratory-scale and pilot-scale wastewater treatment systems

Abstract

The rapid development of science and technology demands that students master essential 21st-century skills, particularly the 4Cs: critical thinking, creativity, collaboration, and communication. This study aims to map senior high school students’ mastery of 4C skills in Renewable Energy learning and to examine differences across the four components. A quantitative descriptive design was applied involving four schools selected through cluster sampling, with each school representing one 4C component. Research instruments consisted of validated and reliable tests and Likert-scale questionnaires. Data were analyzed using descriptive statistics to categorize skill levels and the Kolmogorov–Smirnov test to assess normality. As most data were not normally distributed, the Kruskal–Wallis test was employed to analyze differences among the skills. The results reveal significant variation in students’ 4C performance. Critical thinking and collaboration were categorized as high, while creativity and communication showed more diverse distributions. The Kruskal–Wallis test produced an Asymp. Sig value of < 0.05, indicating significant differences among the four skill domains. These findings suggest that 4C skill development is uneven and influenced by learning experiences and instructional strategies. Therefore, systematic mapping of 4C skills is crucial for curriculum improvement and the design of targeted instructional interventions.

Abstract

Household organic waste management represents a critical environmental challenge requiring practical and sustainable solutions, particularly in densely populated urban areas of developing countries. Biopore Infiltration Holes (BIH) constitute an environmentally friendly technology that can be directly implemented at the household level to accelerate organic waste decomposition while simultaneously enhancing soil infiltration capacity. This study aims to conduct a multidimensional sustainability assessment of BIH implementation for household organic waste management in Kampung Sanitasi, Tabiang Banda Gadang Subdistrict. The research employed a descriptive qualitative approach with sustainability analysis using a modified RAPFISH (Rapid Appraisal for Fisheries) method adapted to organic waste management contexts. Data were collected through structured interviews (n=30 households), field observations, questionnaires, and documentation. Each dimension was evaluated based on multiple attributes scored and analyzed using Multi-Dimensional Scaling (MDS) to generate sustainability indices, supported by Monte Carlo simulation and leverage analysis for reliability testing. The multidimensional sustainability analysis revealed varying levels across dimensions: effectiveness (61.69 - moderately sustainable), efficiency (56.91 - moderately sustainable), and practicality (80.52 - highly sustainable), with an overall sustainability score of 66.37 (moderately sustainable). Community participation and environmental literacy emerged as critical determinants of successful implementation. BIH technology demonstrates strong potential as a sustainable household organic waste management strategy, particularly due to its high practicality. The RAPFISH-based multidimensional assessment provides a robust framework for evaluating and improving community-based environmental technologies.

Abstract

The Baduy are one of the indigenous communities in Indonesia who continue to preserve local wisdom rooted in Sundanese customary law and reside in Lebak Regency, Banten Province. Among the Baduy community, the Baduy Luar demonstrate a relatively adaptive interaction with modernization while maintaining adherence to customary values. This study aims to analyze the forms of local wisdom among the Baduy Luar community, examine the roles of the community and local government in preserving these values, and identify the impacts of modernization on their sustainability. The novelty of this research lies in the use of an ethnoecological perspective to explore the relationship between local wisdom, environmental practices, and socio-cultural adaptation within the context of modernization. This study employed a qualitative approach with an ethnoecological perspective. Data were collected through in-depth interviews with six purposively selected informants consisting of customary leaders, village officials, and representatives of both older and younger generations of the Baduy Luar community, supported by direct observations and documentation. The research was conducted in Kanekes Village, Leuwidamar District, Lebak Regency, on August 10–11, 2024. Data were analyzed using thematic analysis through stages of data reduction, categorization, interpretation, and triangulation of sources and methods to ensure data validity. The findings indicate that local wisdom within the Baduy Luar community is reflected in seven cultural elements: language, knowledge systems, social organization, subsistence and technological systems, livelihood patterns, religious beliefs, and traditional arts. The preservation of these values is primarily maintained through adherence to customary law, while local government involvement is manifested through regional regulations that recognize and protect indigenous traditions. However, modernization has also increased dependence on modern elements, resulting in economic reliance, cultural penetration, social transformation, and the emergence of local resistance as a form of cultural resilience.

Abstract

This study is a quasi-experimental study with a 2x2 factorial design. The aim of this research is to determine the effect of applying inquiry learning model and cognitive styles on the physics learning outcomes and the interaction between learning models and cognitive styles on physics learning outcomes. The population in this study were all physics students of grade XI, while the sample was taken from grades XI 2 and XI 6, which were selected based on the Cluster Random Sampling Technique. The research data were obtained by giving the GEFT test to students before using the learning model in this study, and the physics learning outcomes test was conducted after the application of the inquiry learning model. The data analysis technique used was ANOVA. Based on the inferential analysis, the Fcount (5.12) > Ftable (4.04), can be concluded that there’s a significant difference between students taught with GI and OI learning models, the Fcount (12.63) > Ftable (4.04), can be concluded that there’s a significant difference between students who have FI and FD cognitive styles, and the interaction value Fcount (4.19) > Ftable (4.04), can be concluded that there’s an interaction between learning models and cognitive styles on physics learning outcomes.

Abstract

Several in vitro studies have demonstrated that the combination of plant extracts with antibiotics may reduce the minimum inhibitory concentration (MIC) of antibiotics against resistant microorganisms. Interactions between plant extracts and antibiotics can be synergistic, additive, or antagonistic. This study aimed to evaluate the potential interaction between Cassia alata leaves methanol extract and five selected conventional antibiotics in inhibiting the growth of Staphylococcus aureus ATCC 29213. Antibacterial activity was assessed using the well diffusion and paper strip methods. The methanol extract of C. alata leaves, when tested singly at a concentration of 100 mg/mL, produced an average inhibition zone of 11.74 mm. Four antibiotics, namely ciprofloxacin, clindamycin, chloramphenicol, and tetracycline, exhibited stronger antibacterial activity with inhibition zones ranging from 19.56–27.26 mm, whereas co-trimoxazole showed no inhibitory effect. The combination of C. alata leaves methanol extract with ciprofloxacin, clindamycin, chloramphenicol, tetracycline, and cotrimoxazole resulted in inhibition zones of 22.26 ± 0.703 mm, 22.54 ± 1.222 mm, 17.91 ± 1.094 mm, 17.57 ± 0.652 mm, and 9.30 ± 1.180 mm, respectively. The combined treatments have potential antagonistic effects, as the inhibition zones were smaller than the sum of the individual activities of the extract and antibiotics. Therefore, the combination was considered less effective in suppressing growth of S. aureus ATCC 29213

Abstract

The limited availability of interactive learning media has contributed to the low development of early childhood science skills in kindergarten learning. This study aimed to develop and evaluate an interactive illustrated storybook based on the Story Jumper platform to improve science skills among children aged 5–6 years. The research employed a Research and Development (R&D) approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The study involved two expert validators, one media expert and one material expert, while the field testing was conducted with 20 kindergarten children in Group B at TK Negeri Pembina Ranah Batahan, West Pasaman, Indonesia. Data were collected through validation sheets, practicality questionnaires, observation sheets, and pretest–posttest assessments. The findings indicated that the developed media achieved a very valid category, with validation scores of 91.6% from material experts and 88.8% from media experts. The practicality assessment by teachers reached 94.44%, indicating that the media was highly practical and easy to implement in classroom activities. Furthermore, the effectiveness test showed an increase in children’s science skills, reflected by an N-Gain score of 0.6656 in the moderate-to-high category. The study demonstrates that the Story Jumper–based illustrated storybook can serve as an innovative and effective digital learning medium to support the development of early childhood science skills through interactive and contextual learning experiences

Abstract

This study aims to analyze the effect of tunjung (ferrous sulfate) fixation duration on the color quality and motif clarity of ecoprinted fabrics made from young teak (Tectona grandis) leaves applied to artificial fibers. The research supports the development of eco-friendly natural dye applications and innovation in textile and fashion education. A descriptive quantitative method was used, employing trend and percentage analyses based on evaluations from three textile experts. The assessment covered five aspects: color brightness, motif clarity, motif arrangement neatness, cleanliness, and overall appearance. The results showed that fixation durations of 10, 30, and 60 minutes did not significantly influence color brightness or motif quality, indicating that the dye–fiber bonding equilibrium was achieved within 10 minutes. However, qualitative observations revealed that samples fixed for 30 minutes exhibited slightly clearer motifs due to mild oxidation and pigment redistribution during steaming and drying. These findings suggest that a 10-minute fixation duration is sufficient for efficient dye bonding, while a 30-minute duration may enhance visual definition. The study contributes to sustainable textile innovation by demonstrating that teak leaf pigments combined with tunjung mordant can produce eco-friendly, visually appealing fabrics suitable for fashion and textile learning.
