Abstract

This study aims to analyze the trend of utilizing Augmented Reality (AR) and Virtual Reality (VR) technologies in chemistry learning and to assess their contribution to improving the quality of the learning process. This study uses an integrative Literature Review (ILR) by examining several scientific articles related to the topic discussed. The data used in this study were obtained from research articles found through literature searches using Google Scholar and Semantic Scholar. The articles included in this review are scientific publications equipped with a Digital Object Identifier (DOI) and are relevant to the focus of the study. The selected articles are studies that discuss the use of AR and VR technologies in the teaching and learning process of chemistry, particularly at the secondary education level. The results of the study show that AR technology is widely used in chemistry learning because it can display three-dimensional visualizations of chemical objects. These visualizations help students understand difficult concepts such as molecular structures, chemical reactions, and particle representations, which are often difficult to understand through conventional learning methods. In addition, VR technology provides a more realistic and engaging learning experience through virtual laboratory simulations. Through these simulations, students can conduct practical activities in a safer, more interactive way that closely resembles real laboratory conditions.

Abstract

This innovation aims to design the concept of SMART-LAB STEAM integrated with Augmented Reality (AR) technology and an Adaptive Learning System (ALS) as a novel advancement beyond previous digital laboratory models. Unlike conventional Hybrid Digital Laboratories that merely combine physical and virtual labs, the model proposed in this literature study integrates AR technology for immersive visualization of chemical reactions and an AI-based adaptive system capable of tailoring learning content to each teacher’s individual competency profile. The method employed is a systematic literature review of 35 scientific articles from reputable databases (Scopus, Google Scholar, ERIC) published between 2019–2024. The results indicate that AR integration in virtual laboratories significantly enhances chemistry concept comprehension, while ALS has proven effective in identifying teacher competency gaps and providing personalized learning pathways. The resulting SMART-LAB STEAM model comprises three main components: (1) an AR-Chemistry module for interactive molecular visualization, (2) an AI-based adaptive competency diagnostic system, and (3) cross-disciplinary STEAM projects contextualized to South Sulawesi’s local setting. This innovation is projected to strengthen the professional competencies of chemistry teachers, particularly in technology-based subject mastery and innovative pedagogy.

Abstract

House ants are one of the most common residential pests that can disturb comfort and potentially act as disease vectors. Repeated use of synthetic pesticides may cause negative impacts on human health and the environment; therefore, safer natural repellent alternatives are needed. This study aimed to determine the potential of pandan leaf extract (Pandanus amaryllifolius) as a repellent against black ants (Camponotus pennsylvanicus) and to identify the most effective optimum concentration. The study employed a Randomized Posttest-Only Control Group Design consisting of seven treatment groups, namely a negative control, pandan leaf extract concentrations of 5%, 10%, 15%, 20%, and 25%, and a positive control. Each treatment used 10 ants with four replications, resulting in a total sample of 280 ants. The test was conducted by observing the number of ants crossing the filter paper toward the bait within 10 minutes. Data were analyzed using the Kruskal–Wallis and Mann–Whitney U tests. The results showed that pandan leaf extract has potential as a natural repellent against black ants. The highest repellency percentage was obtained at concentrations of 15%, 20%, and 25%, each reaching 100%, while the 5% concentration showed a repellency rate of 89%. Statistical analysis indicated that all treatment groups were significantly different from the negative control (ρ < 0.05). The 20% concentration was considered the most optimal because it demonstrated high effectiveness without causing ant mortality. Therefore, pandan leaf extract has the potential to be developed as a more environmentally friendly botanical repellent for controlling domestic ants.

Abstract

This study aims to determine the effect of using Pop Up Box media on students’ learning outcomes in the topic of Atomic Models in Grade X at SMA Negeri 10 Bengkulu City. The method used in this research was a quasi-experimental design involving two groups. The sample was selected using a purposive sampling technique, with class XA serving as the experimental group and class XB as the control group. The research instruments included a learning achievement test Data analysis using the Mann–Whitney test yielded a Sig. (2-tailed) value of 0.001 < 0.05, indicating a significant difference in the learning outcomes between the experimental and control classes. This also suggests that the treatment given to the experimental class had an effect on students’ learning outcomes. The results showed that classical mastery learning had not yet been achieved, with a mastery percentage of 45.2%. This condition indicates that the use of Pop Up Box media was not yet fully effective, but it had a positive influence on improving students’ learning outcomes and motivation during the learning process. Overall, the Pop Up Box media can serve as an interesting and appropriate alternative learning medium to help students understand abstract concepts in chemistry. Further development in media design and the application of more varied learning strategies are needed to optimize learning outcomes.
