Abstract

Augmented Reality (AR)-based flashcard learning media is the latest innovation that presents attractive 3D visual animations. This technology can make complex and abstract concepts easier to understand, triggering students' creativity, interest and curiosity in learning. Thus, this media can be an alternative solution in overcoming various learning problems. The purpose of this study is to test the validity of Augmented Reality-based flashcard learning media on cell material in class XI SMA, to ensure its effectiveness in improving student understanding. This research method uses a research and development approach with the ADDIE development model. The results showed that the assessment of the validity of Augmented Reality-based flashcard learning media by material experts included, 93% feasibility aspects, 86% presentation components, 92% language, and 90% AR media, with an average of 90% which included the category "Very Valid." Media experts assessed aspects of display design 70%, text design 76%, and Augmented Reality images 73%, with an average obtained of 74% or "Valid". The validity results obtained from material experts and media experts show an average percentage of 83% on each aspect assessed, which is included in the "Very Valid" category. Based on the results of the study it can be concluded that Augmented Reality-based flashcard learning media is feasible to use to support the learning process.

Abstract

Augmented Reality (AR) is a technology that is one of the new innovations in learning by displaying images in 3D form which makes abstract concepts more real, such as students can observe cell models directly through Augmented Reality visualization. This research aims to test the validity of Augmented Reality-based learning modules in class XI SMA cell material. This type of development research or Research and Development (R&D) uses the ADDIE development model which is carried out up to the development stage, namely validity testing. The results of the validity test show that the Augmented Reality-based learning module on cell material obtained an average validity value of 94% by material experts and validation carried out by media experts showed an average of 75.38% which meets validity standards. Based on these results, this module was declared valid and suitable for use in learning.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas program pendidikan karakter yang diterapkan di Indonesia serta membandingkan efektivitas pembelajaran konvensional dengan model Problem-Based Learning (PBL) terhadap hasil belajar dan pengembangan keterampilan berpikir tingkat tinggi peserta didik. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan analisis kritis dan studi literatur, mengkaji dokumen kebijakan nasional, hasil penelitian terdahulu, jurnal ilmiah, serta laporan terkait implementasi pendidikan karakter di satuan pendidikan. Hasil penelitian menunjukkan bahwa meskipun pendidikan karakter telah diintegrasikan dalam kurikulum, implementasinya masih menghadapi tantangan, seperti keterbatasan keteladanan pendidik dan rendahnya keterlibatan keluarga serta lingkungan masyarakat. Selain itu, penelitian ini juga membandingkan pembelajaran konvensional dengan PBL, yang menunjukkan bahwa PBL lebih efektif dalam meningkatkan hasil belajar kognitif, kemampuan berpikir kritis, kreatif, serta keterampilan kolaborasi dan literasi sains. Namun, implementasi PBL membutuhkan kesiapan guru, dukungan institusional, dan desain asesmen yang sesuai. Penelitian ini memberikan wawasan tentang pentingnya integrasi pendidikan karakter dalam pembelajaran abad ke-21 dan perlunya model pembelajaran yang lebih inovatif untuk mengembangkan keterampilan abad ke-21 di kalangan peserta didik

Abstract

Karst ecosystems possess distinctive edaphic and hydrological characteristics that influence vegetation structure, yet information regarding tree vegetation in the Hungayono karst area remains limited. This study aimed to analyze species composition, vegetation structure, and community patterns of tree vegetation in the Hungayono Karst Ecosystem, Tulabolo Pinogu Resort, Bogani Nani Wartabone National Park. A survey method with purposive sampling was applied at three karst topographic zones representing the lower, middle, and upper areas. Five 20 × 20 m plots were established at each zone, resulting in 15 observation plots. Vegetation data were analyzed using density, frequency, dominance, Important Value Index (IVI), and Principal Component Analysis (PCA). The results recorded 12 species with a total of 61 individuals belonging to the divisions Tracheophyta and Pinophyta. The lower karst zone exhibited the highest species richness and abundance, whereas the upper zone showed a simple and nearly monodominant community structure. Bambusa multiplex dominated Point I with an IVI of 76.38%, Neolamarckia macrophylla dominated Point II with an IVI of 179.5%, and Neolamarckia cadamba dominated Point III with an IVI of 300%. PCA analysis indicated heterogeneous vegetation communities influenced by topography, soil thickness, and microclimatic conditions. These findings highlight the ecological role of karst topographic gradients in shaping tree vegetation structure and provide scientific information for karst habitat management and conservation.

Abstract

Climate change caused by increasing carbon dioxide (CO₂) emissions has become a global issue affecting environmental balance and rising global temperatures. Tropical forest ecosystems, including the Hungayono karst area in Bogani Nani Wartabone National Park, play an important role as carbon sinks through vegetation biomass. This study aims to analyze vegetation density, biomass, carbon content, and carbon sequestration potential in the Hungayono karst ecosystem. The research was conducted using a quantitative descriptive method with purposive sampling techniques at three observation points through the transect quadrat method. Vegetation data were analyzed using allometric equations and IPCC conversion factors. The results showed a tree density of 290 individuals/ha and sapling density of 335 individuals/ha. Total biomass reached 677.79 tons/ha, carbon content was 420.06 tons/ha, and carbon sequestration potential was 1541.63 tons CO₂e/ha. These findings indicate that tree-level vegetation plays a dominant role in carbon storage and climate change mitigation.
