Abstract

This study aims to determine the level of validity of Augmented Reality (AR)-based chemistry learning media using the Assemblr Edu platform on hydrocarbon material. This learning media was developed through the 4D development model (Define, Design, Develop, Disseminate). Validation was carried out by three experts using an instrument in the form of a validation media sheet that includes aspects of content, visual appearance, interactivity, and suitability with learning objectives. The validation results showed that the developed learning media obtained a validity score of 96.39% and was included in the "very valid" category. This shows that the media is suitable for use in the chemistry learning process at the high school level, especially on the topic of hydrocarbons. With AR technology, this media is expected to improve students' conceptual understanding visually and interactively. Based on the results of the study, it can be concluded that this media is effective and valid as a means of supporting innovative modern chemistry learning.

Abstract

This study aims to determine how nano chitosan is produced through the ionic gelation method. The process of making nano chitosan is carried out using variations in chitosan concentrations of 1%, 5%, and 10%, and using a magnetic stirrer. Morphological tests were carried out using Scanning Electron Microscopy (SEM) to observe the shape and size of the particles formed. The addition of TPP (Trisodium Tripolyphosphate) as a crosslinker and certain surfactants are used to increase particle stability. Treatment for ±2 hours showed optimal results in terms of a more homogeneous particle size distribution. Based on the results of SEM observations, it is known that increasing the concentration and time settings and the use of appropriate surfactants can reduce wrinkles in nano chitosan particles. The particle size obtained is in the range of 278–350 nm. Thus, the ionic gelation method has proven effective in producing uniform nano chitosan and has good morphology for further applications.

Abstract

Effective geography education requires instructional media capable of visualizing spatial phenomena in a realistic and interactive manner. Google Earth, a digital mapping application based on satellite imagery and geospatial data, offers an innovative approach to address this need. This study aims to examineimplementation and advantages of Google Earth as a contextual learning medium in geography education through a systematic literature review. The analysis reveals that Google Earth significantly enhances students’ comprehension of key geographical concepts, including absolute and relative location, spatial distribution, spatial interaction, and regional dynamics, through 3D visualizations and geospatial data exploration. Furthermore, its integration supports project-based and inquiry-based learning models aligned with the Merdeka Curriculum. However, several challenges hinder its implementation, such as limited technological infrastructure, low digital literacy among educators and learners, and various technical issues. To fully leverage the potential of Google Earth in geography instruction, strategic implementation planning, teacher training, and institutional support are essential.

Abstract

Teknologi geospasial seperti Sistem Informasi Geografis (SIG), penginderaan jauh, dan pemetaan digital (misalnya Google Earth) semakin berperan penting dalam pembelajaran Geografi, khususnya dalam konteks pembelajaran kontekstual. Teknologi ini menjembatani konsep abstrak dengan realitas spasial di sekitar siswa, sehingga meningkatkan relevansi dan pemahaman materi. Penelitian ini bertujuan mengkaji konsep integrasi teknologi geospasial dalam pembelajaran Geografi di SMA, serta mengidentifikasi strategi dan tantangan dalam penerapannya. Menggunakan metode studi literatur, artikel ini menganalisis berbagai sumber akademik terkait implementasi teknologi geospasial di pendidikan. Hasil kajian menunjukkan bahwa teknologi ini dapat memperkuat keterampilan berpikir spasial, analitis, dan kritis siswa, meskipun masih menghadapi kendala seperti rendahnya kompetensi guru. Kesimpulannya, integrasi teknologi geospasial berpotensi besar meningkatkan kualitas pembelajaran jika didukung oleh sumber daya dan kebijakan yang memadai.

Abstract

Despite the importance of understanding reaction rate concepts in chemistry, students often struggle with abstract content and low engagement in traditional learning settings. Conventional teaching methods tend to emphasize rote memorization, limiting opportunities for critical thinking and problem-solving. This study investigated the influence of ChatGPT-assisted Problem-Based Learning (PBL) on students’ learning outcomes in reaction rate material. A quasi-experimental design with a non-equivalent control group was employed, involving two Class XI groups at SMA Negeri 1 Kabila: XI A as the experimental group (using ChatGPT-assisted PBL) and XI B as the control group (receiving conventional instruction). Learning outcomes were measured using an essay test aligned with cognitive indicators. Results showed greater improvement in the experimental group, with a posttest average of 78.68 compared to 69.23 in the control group. Independent sample t-test analysis revealed a significant difference between groups (p = 0.001 < 0.05), and the N-Gain score indicated a higher improvement category in the experimental class. These findings suggest that integrating ChatGPT into PBL enhances students’ understanding of reaction rate concepts and supports more effective learning, highlighting the potential of AI-assisted strategies in chemistry education.
