Abstract

In this study, YBa2Cu3O7-δ (YBCO) superconductors were synthesized using a thermal treatment method with the addition of 1.0 wt. % SnO₂. The synthesis of YBCO employed nitrate-based precursors and polyvinylpyrrolidone (PVP) as a capping agent to enhance homogeneity during the synthesis process. All samples were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Four-point probe (4PP). TGA results of the pure YBCO sample confirmed the complete transformation of nitrate-based precursors into oxide forms prior to the formation of the YBCO phase. XRD pattern revealed that Y123 as a major phase and Y124 as a minor phase in all samples with orthorhombic crystal structure were preserved. However, the peak intensity of the Y123 was pronounced with the addition of the SnO2 sample, suggesting the enhancement phase formation due to the presence of SnO₂. The electrical resistivity measures revealed a sharp superconducting transition in all samples. However, the reduction in superconducting transition temperatures for the SnO2 addition were observed where the Tc-onset decreased from 91.70 K to 89.25 K for the YBCO and YBCO + 1.0 wt.% of SnO2, respectively. This also exhibited the broadening of transition width, ΔTc indicating the suppression of superconducting properties with SnO₂ inclusion. SEM analysis showed notable differences in microstructure. The pure YBCO sample exhibited a larger average grain size of 1.32 µm, while the YBCO + 1.0 wt. % SnO2 sample formed small and rounded grains with smoother edges, potentially impacting intergranular connectivity and charge transport. Therefore, the addition of 1.0 wt. % SnO2 to YBCO enhanced the formation of the Y123 phase but adversely affected the superconducting transition temperature and microstructural features. These findings highlight the dual role of SnO2 in promoting phase purity while modifying grain morphology and electrical performance, offering insight into the optimization of dopants in high-temperature superconductors

Abstract

Polymer gel dosimeters are fabricated from radiation sensitive chemicals which, upon irradiation, polymerize as a function of the absorbed radiation dose. These dosimeters, which uniquely record the radiation dose distribution in three-dimensions (3D), have specific advantages when compared to one-dimensional dosimeters, such as ion chambers, and two-dimensional dosimeters, such as film. This research aims to identify and analyze research trends of Polymer gel dosimeters. This research method is descriptive and analytical.

Abstract

The application of polymer dose gels is limited by the sensitivity of dose readout methods and dose gel properties. It is a challenge to find suitable dosimeters for registration of doses delivered to the target by orthovoltage therapy units. The application of metal-particle-enriched polymer composites for dose registration in X-ray therapy might be an elegant solution, especially if recent dose-reading technologies exploring advantages of different physical phenomena are involved. This research aims to identify and analyze research trends of Polymer thin film dosimeters. This research method is descriptive and analytical. The data used in this research was obtained from documents indexed by Google Scholar from 2016-2025 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines.

Abstract

Polymer-based radiation dosimeters have attracted significant attention in recent years due to their capability to measure complex radiation dose distributions in radiotherapy applications. This study aims to analyze the research trends related to polymer film and polymer gel dosimetry used in radiotherapy through a systematic literature review and bibliometric analysis. The study employed the PRISMA methodology to systematically identify and select relevant publications from the Scopus and SINTA databases. A total of 30 articles published between 2018 and 2025 were included in the analysis. Bibliometric analysis was conducted using VOSviewer to examine publication trends, keyword co-occurrence networks, and research collaboration patterns. The results indicate a steady increase in research publications related to polymer dosimetry over the past decade. Keyword clustering analysis revealed several dominant research themes, including polymer gel dosimetry, radiation polymerization, dose distribution measurement, polymer film dosimeters, and nanoparticle-enhanced polymer materials. Among these topics, polymer gel dosimetry remains the most widely studied due to its capability to record three-dimensional radiation dose distributions. However, recent studies have increasingly explored polymer film dosimeters and nanocomposite materials to improve radiation sensitivity and dosimetric performance. Overall, the findings highlight the rapid development of polymer dosimetry technologies and their growing importance in modern radiotherapy quality assurance. Future research should focus on developing advanced polymer nanocomposites and integrating imaging-based dosimetry techniques to improve radiation dose measurement accuracy and clinical applicability.

Abstract

High temperature superconductor of YBa2Cu3O7-δ (Y-123) has been synthesised using the modified thermal decomposition method (MTD). In this work, a pure Y-123 sample is produced using an acetate-based material as a precursor and sintered at 980 oC. The study on the phase formation, superconducting properties and microstructural characteristics of pure Y-123 was investigated using X-ray diffraction (XRD), four-point probe (4PP) and scanning electron microscopy (SEM) respectively. XRD analysis confirmed the formation of a single-phase orthorhombic Y-123 crystal structure with an orthorhombicity of 0.008, indicating high phase purity without detectable impurity phases. Electrical measurements revealed a sharp superconducting transition with a critical onset temperature, Tc-onset of 97.3. SEM observations showed plate-like grains with an average grain size of 2.25 µm and good grain connectivity. These results demonstrate that the modified thermal decomposition technique is an effective approach for producing phase-pure YBCO superconductors with excellent structural and superconducting properties, highlighting its potential for advanced superconducting applications

Abstract

Creativity is a crucial aspect of physics learning that is often overlooked due to the dominance of conventional learning methods. This study aims to analyze the influence of the Jigsaw cooperative learning model with a multimodal approach on the creativity of grade XI students at MA Nurul Iman. This research is a quasi-experiment using a non-equivalent control group design. The research instrument consisted of a creativity test in the form of four complex essay items that were declared valid (rxy>0,443) and reliable (r11>0.443). The results showed that the average posttest score of the experimental class (78) was higher than the control class (65.05). The Independent Sample T-test results obtained a significance value (2-tailed) of 0.002 < 0.05, so Ha was accepted. It can be concluded that the implementation of the Jigsaw model with a multimodal approach has a significant effect on students' creativity. The synergy between individual responsibility in groups and the diversity of representation modes effectively stimulates indicators of fluency, flexibility, originality, and elaboration.

Abstract

Learning media functions to facilitate students' understanding of scientific concepts in a concrete and visual way. PjBL is one of the learning models recommended in the independent curriculum. This model focuses on projects (real tasks). In this case, community service activities were carried out at SMP Negeri 3 Labuapi. The purpose of this activity is to determine the response and level of student satisfaction with the food chain board learning media. The activity method used is the service method which includes three steps, namely: preparation, implementation and evaluation. After the training activities were completed, all participants were asked to fill out a training assessment questionnaire. Then, the data obtained was analyzed descriptively and quantitatively. The results of this research show that students responded very well to the learning media that had been created and developed. This can be seen from the average score of 83.73% or rounded up to 84%, which is in the Strongly Agree category. Therefore, it can be concluded that the socialization activities and use of food chain board media located at SMP Negeri 3 Labuapi went very well and satisfactorily.
