Abstract

The low level of students’ scientific literacy, particularly in understanding biodiversity concepts and conservation efforts, remains one of the challenges in biology learning at the secondary school level. Learning activities that are predominantly theoretical and do not optimally utilize the surrounding environment as a learning resource result in students’ limited contextual understanding and environmental awareness. Therefore, learning activities that connect biological concepts with real-life environmental conditions are needed, one of which is through the introduction of botany. This community service activity aimed to improve the scientific literacy of Grade X students at SMAN 2 Narmada on biodiversity topics through botany-based learning using a contextual learning approach. The activity was conducted in the form of teaching assistance employing the service-learning method, which included the stages of preparation, implementation, and evaluation. The learning implementation utilized interactive teaching materials and the school environment as learning resources. The evaluation was carried out through botany planting activities in the classroom garden as a form of applying the knowledge gained by the students. The results indicated an improvement in students’ understanding of biodiversity concepts, increased student engagement in the learning process, and the development of environmental awareness. Although several challenges were encountered, such as student absenteeism and a lack of focus among some students, overall, the activity was successfully implemented and had a positive impact on biology learning. This botany introduction activity has the potential to be developed as a sustainable learning strategy to enhance students’ scientific literacy.

Abstract

Mangrove ecosystems play a crucial role in maintaining the ecological balance of coastal environments by supporting biodiversity and protecting shorelines. This study aimed to identify the species composition and analyze the vegetation structure of mangroves in the Bagek Kembar area, Sekotong, West Lombok, Indonesia. The research was conducted in January - May 2026 using a descriptive-exploratory approach with purposive sampling. Vegetation data were collected from 9 quadrats using line transect and quadrat methods. Data were analyzed using the species diversity index (H′), species evenness index (E), species dominance index (D), and Important Value Index (IVI). A total of 306 individuals belonging to five mangrove species were recorded, namely Avicennia marina, Rhizophora apiculata, R. mucronata, R. stylosa, and Sonneratia alba. The species diversity index (H′) was 1.30, indicating moderate diversity, the species evenness index (E) was 0.80, indicating high evenness, and the species dominance index (D) was 0.30, indicating low dominance. Rhizophora mucronata showed the highest Importance Value Index of 115.86, indicating its dominant ecological role in the mangrove community. These findings indicate that the mangrove vegetation in the Bagek Kembar area is in relatively good condition and highlight the ecological importance of the dominant species as a priority for conservation and sustainable mangrove ecosystem management.
