Abstract

Metacognition skills and concept understanding can be improved through learning strategies that lead to improved thinking skills. Learning strategies are used to achieve learning objectives effectively and efficiently with the help of virtual laboratories as learning media and provide opportunities to get information more efficiently, also make students aware of their thinking control, so they know what to do and how to do it and students learn to actively reconstruct their conceptual understanding. This study aims to analyse the development of virtual laboratory integrated learning strategies that can improve metacognition skills and concept understanding in biology learning. This type of research is method using the literature study method. The development of this learning strategy adapts the Inquiry, Discovery and Cooperative learning strategies to produce the SIRNI strategy. The syntax of the SIRNI learning strategy is Stimulation, Idea Generation, Research, Conclusion, Reflection This learning strategy is expected to help improve students' metacognition skills and concept understanding so that students' mastery in processing learning information increases, helps students solve problems related to misconceptions and learning errors, and increases students' desire to learn.

Abstract

The student's cognitive load is high, and the level of thinking and communication skills is low. So, the chunking technique combined with writing thinking is implemented. The purpose of this study was to determine the difference in communication skills of students of circulatory system material taught with chunking techniques combined with writing is thinking, chunking techniques, and lecture techniques in class XI students of SMA Negeri 20 Gowa in the 2024/2025 school year. This type of research includes experiments in the form of a pretest, posttest, and nonequivalent control group design. Sampling technique with purposive sampling with specific consideration in the form of almost the same initial ability of students from three treatment classes where class XI. 1 (experimental class), XI.2 (positive control class), and XI.3 (negative control class), each of which totaled 30 students. Data acquisition using non-test instruments to see students' communication skills and teaching module implementation sheet. Hypothesis testing uses the Anacova test because the data is normally distributed and homogeneous. The results of hypothesis testing showed that the significance value was <0.000. This shows the sig value < α (0.05), so it can be concluded that H0 is rejected and H1 is accepted. This means that there are differences in the communication skills of students who are taught with chunking techniques combined with writing thinking (experimental class), chunking techniques (positive control class), and lecture techniques (negative control class) on human circulatory system material.

Abstract

This study aims to determine the shape, color, and location of sori as well as the presence or absence of annulus in ferns (Pteridophyta) of the Polypodiaceae and Tectariaceae families in the Ato Watu Waterfall area, Amonggedo District, Konawe Regency, Southeast Sulawesi. The method used in this study was qualitative descriptive research with an exploratory method by exploring the Ato Watu Waterfall area to collect fern samples that had sori. The results of the study found six species of ferns in the Polypodiaceae family, including Drynaria quercifolia (L.), J, Lemmaphyllum accedens (Blume), Leptochilus henryi (Baker) X.C.Zhang, Microsorum membranifolium (R.Br.) Ching, Pyrrosia longifolia (Burm.fil.) C.V.Morton, Selliguea heterocarpa BI., FI. Jav (Mehltreter, et al., 2010: 835-838) And 5 species of ferns from the Tectriaceae family, including Tectaria angulata (Sw.) S. Chandra, Tectaria aurita (Sw.) S. Chandra, Tectaria barberi (Hook), Tectaria devaxa (Kze) Copel, Tectaria fuscipes (Wall. ex Bedd) C. Chr,. Of the 6 species of the Polypodiaceae family, 5 species of the Tectariaceae family found, they have different sorus characteristics, and each species has an annulus (Shin & Keun, 2017: 317-320).

Abstract

The exploitation of small islands (area less than 2000 km²) for mining activities can negatively impact vegetation conditions, as observed on Manuran Island in West Papua Province. This study aimed to assess the environmental impact of mining on Manuran Island by analyzing spatial and temporal changes in vegetation indices using the Normalized Difference Vegetation Index (NDVI) method to classify land cover using Landsat 7 ETM satellite imagery and Landsat 8 OLI imagery. The NDVI classification grouped four land cover types: non-vegetation, open soil, sparse vegetation, and moderate vegetation. The analysis revealed a significant increase in non-vegetation land cover from 2002 to 2015, indicating a direct impact from mining activities. However, between 2015 and 2025, the area classified as non-vegetation tended to decrease gradually. Conversely, open soil and sparse vegetation experienced a notable decline from 2002 to 2015, followed by a minor decrease in the subsequent period. In contrast, moderate vegetation steadily increased from 2002 to 2025, suggesting a recovery process in the vegetation. To accelerate the environmental and vegetation recovery process, several revegetation strategies, including reclamation, selection of native and pioneer species, and soil improvement techniques, are recommended. The findings of this study suggest that the reduction in mining activity intensity on Manuran Island has contributed positively to ecosystem recovery and that direct interventions are needed to accelerate environmental recovery.
