Abstract

Research on the utilization of Gold Nanoparticles (GNPs) has rapidly advanced in recent decades, particularly in the biomedical field for cancer detection and therapy. GNPs have unique characteristics, such as nanometer size, high chemical stability, modifiable optical properties, and good biocompatibility, making them ideal candidates for applications in nanomedicine. This literature reviews the utilization of GNPs in cancer detection through local surface plasmon resonance (LSPR)-based imaging techniques, signal enhancement in Raman spectroscopy, and the delivery of specific diagnostic agents. Additionally, in cancer therapy, GNPs are used for photothermal, photodynamic, and targeted drug delivery, which can enhance therapeutic efficacy and reduce side effects on healthy tissues. This literature review also covers the main challenges in the development of GNP-based technologies, including toxicity, in vivo stability, and production scalability. The results of this study indicate that GNPs have great potential for clinical application, although further research is needed to address technical and ethical constraints before they can be widely implemented in cancer treatment in humans

Abstract

The process of making walnut bread is a dynamic process where the flour components and other ingredient mixtures undergo physicochemical changes. The aim of this study is to explore scientific concepts both at the preparation, process and product stages in the form of walnut bread. Analysis was also carried out to determine the integration of sin concepts according to Fogarty's view. This study uses descriptive qualitative methods. Data collection techniques through libraries. The results of the analysis show that the process of making walnut bread involves scientific concepts including physics, chemistry and biology. These concepts include colloids, collisions, fermentation, temperature and heat, reaction rates, Maillard reactions and caramelization and spoilage processes in food..

Abstract

This study aims to explore how students’ cognitive processes are formed and developed through their engagement with thermodynamics learning using culturally-based comics. Employing a qualitative case study design, the research involved twelve physics education students who had completed thermodynamics coursework. The learning medium used was the Longbumbung Series, an educational comic that integrates narrative and visual representations of local cultural life with thermal physics concepts. Data were collected through participatory observation, in-depth interviews, and students’ written reflections, and analyzed thematically. The findings indicate that incorporating local culture into comics not only enhances students’ affective engagement but also stimulates higher-order cognitive processes such as conceptual interpretation, scientific inference, and analytical articulation. Culture serves as a representational structure that bridges abstract concepts into contextual and reflective understanding. These findings highlight the importance of strategically integrating local cultural elements into science media and pedagogy design to foster deeper intellectual engagement and transformative learning experiences.

Abstract

Pembelajaran yang berorientasi untuk mencapai Kriteria Ketuntasan Minimal (KKM) mengakibatkan perkembangan keterampilan abad 21 siswa seperti komunikasi dan kolaborasi sering terabaikan, terutama bagi siswa yang berkepribadian introvert. Keterampilan tersebut perlu dikembangkan terutama bagi siswa introvert karena mereka mengalami kesulitan dan membutuhkan waktu untuk bekerja sama atau mengemukakan pendapat. Penelitian ini bertujuan untuk menganalisis keterampilan komunikasi dan kolaborasi siswa introvert melalui Pendekatan Culturally Responsive Teachng. Penelitian dilaksanakan di SMA Negeri 5 Kota Tidore Maluku Utara tahun pelajaran 2020/2021. Subyek penelitian adalah siswa kelas XI IPA yang berkeperibadian introvert. Penelitian ini menggunakan metode kualitatif dengan pendekatan interpretatif. Penentuan subjek penelitian menggunakan purposive sampling melalui tes Eysenck Personality Inventory (EPI), sedangkan teknik pengumpulan data menggunakan observasi, reflektif jurnal, dokumentasi dan wawancara. Hasil penelitian menunjukkan bahwa keterampilan siswa introvert berkembang dalam berkolaborasi dengan teman-temannya. Intensitas komunikasi mereka juga mengalami peningkatan. Penerapan pendekatan Culturally Responsive Teaching menjadikan siswa introvert memiliki motivasi, keberanian, dan percaya diri untuk mengemukakan pendapat baik kepada teman maupun guru serta mampu bekerja sama dengan siswa lain dalam kelompoknya.
