Abstract

This study aimed to analyze the abiotic factors and morphological characteristics of mangrove vegetation in the Langsa Mangrove Forest area, Aceh. The research was conducted through direct field exploration using descriptive–quantitative methods, involving the observation of vegetative and generative organs of mangrove species and measurement of environmental parameters such as salinity, pH, temperature, and total dissolved solids (TDS). Morphological data were documented and identified using field guides, while abiotic parameters were measured in situ using standard instruments (pH meter, salinometer, DO meter, and thermometer). The results identified eleven mangrove species, including Rhizophora mucronata, R. Apiculata, R. Stylosa, Avicennia alba, Kandelia obovata, Ceriops tagal, Xylocarpus granatum, Acanthus ilicifolius, Scyphiphora hydrophyllacea, Acrostichum aureum, and Casuarina equisetifolia. Each exhibited distinctive morphological adaptations such as prop roots, pneumatophores, thick waxy leaves, and viviparous fruits that support survival in high-salinity and anaerobic conditions. The abiotic data showed an average salinity of 0.92% (≈8.82 ppt), water pH 6.68, soil pH 5.74, temperature 29.18 °C, and electrical conductivity 17.25 mS/cm—values within the optimal range for mangrove growth. These findings indicate that the Langsa mangrove ecosystem remains stable and ecologically healthy, supporting high species diversity. The study concludes that the interaction between abiotic conditions and plant morphology determines the ecological balance of the Langsa mangrove habitat, highlighting the importance of sustainable management and conservation of this coastal ecosystem. Keywords: abiotic factors, environmental parameters, Langsa Mangrove Forest, mangrove ecology, morphological adaptation

Penelitian bersifat deskripstif dengan metode eksploraif dan inventarisasi pada tegakan pohon Kemiri (Aleurites moluccanus), pohon Pinang (Areca cathecu) dan pohon Kakao (Theobroma cacao). Teknik Purposive Sampling dengan menggunakan transek vertikal ke atas. Hasil penelitian menunjukkan bahwa pada pohon Kemiri (Aleurites moluccanus) ditemukan 11 jenis lichens dengan jumlah 91 spesies, pada pohon Pinang (Areca cathecu) ditemukan 10 jenis lichens dengan jumlah 51 spesies dan pada pohon Kakao (Theobroma cacao) ditemukan 9 jenis lichens dengan jumlah 54 spesies. Keanekaragaman lichens yang tinggi pada pohon Kemiri (Aleurites moluccanus) dengan indeks nilai penting (H′= 26,84) diikuti pada pohon Kakao (Theobroma cacao) dan pohon Pinang (Areca cathecu). Jumlah lichens dari ketiga pohon tersebut sebanyak 14 jenis dari 7 famili dengan 4 tipe talus (crustose, foliose, fructicose dan squamolose). Karakteristik habitat yang mendukung pertumbuhan dan perkembangan lichens pada lokasi penelitian berada pada suhu 27 0C – 29 0C, kelembaban 61% - 66%.

Abstract

Photosynthesis and chemical reactions are essential concepts in biology and chemistry learning; however, students often experience difficulties in understanding these topics due to their abstract characteristics and complex processes. The integration of artificial intelligence (AI) in interactive learning media is considered capable of improving students’ conceptual understanding and engagement in science learning. This study aimed to develop and evaluate an AI-Based Interactive PowerPoint on photosynthesis and chemical reactions for biology and chemistry education. This research employed a Research and Development (R&D) approach using the 4D model, consisting of Define, Design, Develop, and Disseminate stages. The developed media integrated AI-assisted explanations, animations, interactive quizzes, and visual simulations. The research participants were students from biology and chemistry education programs. Data were collected through expert validation sheets, practicality questionnaires, and pretest-posttest instruments. The obtained data were analyzed descriptively and quantitatively using percentage analysis and N-gain scores. The findings showed that the AI-Based Interactive PowerPoint achieved a very valid category based on expert assessment and was considered highly practical by students and lecturers. Furthermore, the media effectively improved students’ understanding of photosynthesis and chemical reaction concepts, as indicated by the increase in posttest scores and positive student responses toward the learning process. The integration of AI features also encouraged more interactive, visual, and student-centered learning experiences. In conclusion, the AI-Based Interactive PowerPoint is feasible and effective as an innovative learning medium for integrated biology and chemistry education. The developed media can support meaningful science learning and enhance students’ engagement and conceptual understanding in the digital learning era.

Abstract

Electromagnetic wave (EMW) radiation from mobile devices has raised public health concerns due to its potential biological effects on rapidly regenerating tissues such as the oral mucosa. This study quantitatively analyzed nuclear morphological alterations in oral mucosal epithelial cells following controlled EMW exposure. A quasi-experimental pretest–posttest control group design was conducted with 30 healthy participants aged 18–25 years, randomly assigned to control (n = 15) and treatment (n = 15) groups. The treatment group was exposed to EMW at 1800 MHz for 60 minutes per day over 14 consecutive days, using an active smartphone placed 1 cm from the right cheek during a simulated voice-call condition. The control group received no direct exposure. Buccal epithelial cells were collected via oral swab, fixed in Carnoy’s solution, stained with hematoxylin–eosin, and observed under a light microscope at 400× magnification. Quantitative assessment focused on three types of nuclear abnormalities: pyknosis, karyorrhexis, and karyolysis. The Independent Samples t-test showed a significantly higher mean number of nuclear abnormalities in the exposed group than in the control group (12.47 ± 3.15 vs. 4.86 ± 1.92 cells/field; p < 0.001). Pyknosis was the most frequent alteration (58.3%), followed by karyorrhexis (26.7%) and karyolysis (15.0%). All procedures were approved by the institutional ethics committee. In conclusion, short-term exposure to 1800 MHz EMW from mobile devices under controlled conditions can induce measurable degenerative nuclear changes in oral epithelial cells, suggesting cellular susceptibility to non-ionizing radiation at the cytomorphological level.

Abstract

ABSTRACT Flood disasters in the Barus area, Central Tapanuli Regency, caused psychosocial impacts and disrupted community-based Islamic education services, particularly local religious learning activities. This condition required assistance efforts aimed at restoring community psychological well-being while strengthening post-disaster Islamic educational services. This community service program aimed to provide psychosocial assistance and strengthen community-based Islamic education services for flood-affected communities in the Barus area, Central Tapanuli Regency. The program employed a participatory approach through field observation, community needs assessment, psychosocial assistance, educational and spiritual activities, and capacity strengthening for community-based Islamic education providers. The target participants included children, adolescents, Qur’anic teachers, and flood-affected residents. The activities contributed to increased learning motivation among children, improved emotional recovery within the community, and greater participation in community-based Islamic education activities. Strengthening educational services was also achieved through the provision of learning media, religious activities, and collaboration with local community leaders. Psychosocial assistance and the strengthening of community-based Islamic education services positively contributed to post-flood recovery efforts in the Barus area. The program supported the social, emotional, and spiritual resilience of the community while reinforcing the sustainability of Islamic education in disaster-affected areas. Keywords: Psychosocial Assistance, Islamic Education, Community Service, Post-Disaster Recovery, Flood Disaster.
