Abstract

This study aims to explore the perceptions of students toward Project-Based Learning (PjBL) in P5 projects for enhancing writing skills at Islamic Boarding Schools (IBS). It seeks to address key questions about students’ experiences, the impact of PjBL on writing development, the challenges encountered, and strategies for improvement. Adopting a convergent parallel mixed methods design, data were collected using an online questionnaire and semi-structured interviews. The questionnaire involved 84 students from As-Syifa Islamic Boarding School Sagalaherang Subang, while 12 participants, purposefully selected based on English proficiency (basic, intermediate, advanced) and willingness to participate, were interviewed for in-depth insights. Quantitative data were analyzed descriptively, and qualitative data were coded thematically. Findings reveal that PjBL in P5 projects positively influences students’ writing skills through real-world applications, collaborative tasks, and engaging activities. However, challenges such as time constraints, limited vocabulary, and group dynamics were noted. To enhance PjBL outcomes, students proposed extending time for writing tasks, providing immediate feedback, and integrating digital tools for autonomous learning support.

Abstract

With chemotherapy and radiation therapy being the most common cancer treatments today, there are questions about their effectiveness and risks.Therefore, an alternative method that does not have significant side effects is needed, such as magnetic hyperthermia therapy (HM).The mass of magnetic nanoparticles (MNP) and the coating of MNP as anti-cancer agents play a very important role in optimizing the HM method, characterized by the Specific Absorption Rate (SAR) value.This study examines the effect of the mass of iron oxide magnetic nanoparticles with a silver coating (Fe3O4/Ag) on the Specific Absorption Rate (SAR) value. MNP Fe3O4/Ag was synthesized using the green synthesis (GS) method with Moringa oleifera (MO) plant extract.The results of this study show that GS-NPM Fe3O4/Ag has a crystal size between 42.69 - 43.58 nm with a bandgap energy of 2.50 eV, and contains functional groups O-H, C-H, N-Ag, Fe-O, and Fe-O-Si.There was a temperature change in the NPM Fe3O4/Ag for all mass variations, ranging from 0°C to 14.2°C over a period of 600 seconds, using a frequency of 15 kHz and an alternating magnetic field amplitude of 150 Oe.This temperature change indicates that the greater the mass of the NPM sample, the higher the NPM temperature. The lowest and highest SAR values obtained, consecutively, were 0.43 W/g at a mass of Fe3O4/Ag 0.125 grams and 1.11 W/g at a mass of 0.025 grams.

Abstract

This study carries some practical implications for Indonesian EFL classrooms, particularly about the role of vocabulary in the improvement of reading comprehension, which could be useful for EFL teachers in designing successful lessons. The present study was conducted to investigate, in addition to the correlation of vocabulary skill and reading comprehension, whether vocabulary predicts reading performance. Accordingly, the quantitative correlational research design was employed in the study. Subjects were thirty-nine tenth-grade students from MA Daarul Ukhuwah. Students' receptive vocabulary was assessed with a 20-item vocabulary test. The school assessed reading level with an end-of-semester test. The Shapiro-Wilk tests suggested that the data were not normally distributed, and therefore, Spearman's rho correlation and simple linear regression analyzes were conducted to analyze the data. The correlation between rating comprehension and vocabulary knowledge was large and moderate (rs = .363, p = .023). Vocabulary knowledge was responsible for 12.4% of the variance in reading comprehension scores (R² = .124). From an educational point of view, the results suggest that instruction in contextualized vocabulary should be augmented by inferencing and building background knowledge to improve reading comprehension. Future studies should employ larger and more diverse samples, use item-level, psychometrically validated instruments, and employ more rigorous methods for calculating effect sizes to better inform classroom practice.

Abstract

This study explores pre-service English teachers’ perceptions of Global Englishes-informed language teaching within a teacher education context. Drawing on a quantitative survey design, the study examines three key dimensions: attitudes, confidence, and intentions toward the pedagogical application of Global Englishes. The participants were students enrolled in a master’s degree program in English education. Data were collected using a structured questionnaire and analyzed using descriptive statistics. The findings indicate that participants generally demonstrate positive attitudes toward Global Englishes. However, their confidence in applying its principles was comparatively lower than their attitudes and intentions. The results also suggest that prior exposure to different forms of English, such as through media and interaction, may be associated with more flexible perceptions of English use. This study provides exploratory insights into how pre-service teachers conceptualize Global Englishes and its relevance for teaching. The findings highlight the importance of addressing not only attitudes but also confidence and pedagogical readiness in teacher education programs. These results may inform future research and contribute to ongoing discussions on Global Englishes-informed pedagogy in English language teaching.

Abstract

This study aimed to synthesize and evaluate the photocatalytic performance of CoFe₂O₄/Cdots nanocomposites prepared via green synthesis method using Moringa oleifera leaf extract and watermelon rind waste as eco-friendly precursors. The synthesis involved a co-precipitation process for CoFe₂O₄ formation and a hydrothermal route to produced Cdots, followed by composite fabrication. The materials were characterized using XRD, UV-Vis Spectrophotometer, and VSM analyses to determine their crystalline structure, optical, and magnetic properties. The results showed that the incorporation of Cdots increased the optical band gap (3.15 eV) compared to pure CoFe₂O₄ (2.64 eV) and improved soft magnetic behavior. Photocatalytic tests under UV irradiation using Methylene Blue as a model pollutant revealed a degradation efficiency of 91.9% for CoFe₂O₄/Cdots at an optimum catalyst mass of 0.07 gr, significantly higher than 60,8% achieved by pure CoFe₂O₄. The enhanced performance is attributed to the synergistic interaction between CoFe₂O₄ and Cdots, which promotes charge separation, initial adsorption, and reactive radical generation. These findings indicate that the CoFe₂O₄/Cdots nanocomposite is a promising eco-friendly photocatalyst for wastewater treatment applications.

Abstract

CoFe2O4/Cdots nanocomposites have been successfully synthesized by combining CoFe2O4 synthesized from Moringa oleifera (MO) extract and Cdots synthesized from watermelon rind. CoFe2O4/Cdots nanocomposites were synthesized using a green synthesis method. This study began with the synthesis of MO, CoFe2O4, Cdots, then CoFe2O4/Cdots. Thus, CoFe2O4/Cdots-10, CoFe2O4/Cdots-20, and CoFe2O4/Cdots-30 were obtained, each based on variations in the concentration of Cdots to CoFe2O4, that is 10, 20, and 30 ml. After the synthesis process, characterization was carried out using FTIR, UV-Vis and TEM. The results of FTIR testing on nanocomposites showed the presence of typical functional groups of Cdots and typical functional groups of CoFe2O4. The combination of both produces a wave number shift caused by the emergence of new bonds between Cdots and CoFe2O4. The results of UV-Vis testing show that the addition of Cdots does not significantly affect the absorbance, but there is a shift in the absorbance peak to the left along with the addition of Cdots variations. This causes the band gap energy value to increase. The results of TEM testing show that the morphology of both samples is semi-spherical and tends to agglomerate along with the addition of Cdots. However, the addition of Cdots concentration results in a smaller particle diameter and is relatively more uniform. This results in a larger surface area and is effective for use in various applications. The results of Selected Area Electron Diffraction (SAED) show that the diffraction ring with the presence of a lattice is still in the CoFe2O4 phase.     Kata kunci: CoFe₂O₄/Cdots nanocomposite, green synthesis, FTIR, UV–Vis, TEM, optical properties, morphology.

Abstract

This study aimed at analyzing the correlation between reading and listening in TOEFL ITP test and how much reading predicts listening. It involved 50,684 reading and listening scores in 2015-2019 test periods of undergraduate students in one of the state universities in Malang. The data were collected by using standardized TOEFL ITP issued by ETS. Using Pearson Correlation Product Moment and linear regression analysis, the result demonstrated reading and listening had significant, linear, and strong correlation (.682), and reading significantly predicted 46.5% variance of listening. The results lead to the hypothesis that two language input skills, reading and listening significantly correlated and predicted one another. The result also suggested that correlation language skills not only occurred among reading and writing and listening and speaking, but also it happened in reading and listening. Moreover, the results suggested the combination of reading and listening activities in classroom activities.
