Abstract

Penelitian ini mengkaji karakteristik substrat dan morfologi rumput laut di kawasan pesisir Aceh Selatan, Provinsi Aceh. Tujuan penelitian adalah untuk mengidentifikasi komposisi jenis rumput laut, tipe substrat yang ditempati, serta perbedaan morfologi masing-masing spesies. Metode yang digunakan adalah kombinasi line transect dan quadrat transect dengan pengambilan sampel di zona intertidal dan subtidal. Hasil penelitian menemukan 32 spesies rumput laut yang tergolong dalam tiga kelas: Chlorophyceae (11 spesies), Phaeophyceae (11 spesies), dan Rhodophyceae (10 spesies). Substrat keras seperti karang mati dan batu dominan dihuni oleh rumput laut dengan life form lithofitik (66%), sedangkan substrat lunak seperti pasir dan kerikil didominasi oleh rhizophitik (28%). Karakteristik morfologi rumput laut bervariasi, terutama pada struktur holdfast, stipe, dan blade, yang mencerminkan adaptasi terhadap kondisi lingkungan. Alga coklat (Phaeophyceae) memiliki morfologi paling kompleks, cocok untuk perairan berarus kuat, sementara alga hijau (Chlorophyceae) dan alga merah (Rhodophyceae) lebih adaptif di perairan tenang atau berarus sedang. Hasil penelitian ini memberikan informasi penting untuk konservasi dan budidaya rumput laut berkelanjutan dengan mempertimbangkan kesesuaian substrat dan ketahanan morfologis spesies.

Abstract

Each tribe has a tradition of ethnobotanical plant utilization and management, one of which is the Tamiang tribe. The community realizes the potential of plant utilization, thus creating considerable economic opportunities for bioprospection. This study used the Participatory Rural Appraisal (PRA) method to collect data by actively involving the community. Semi-structured interview techniques were conducted to explore ethnobotanical information from the Tamiang tribe. From the results of the Slovin analysis, 600 respondents with an age range of 35 to 94 years were obtained. Snowball sampling was used to select respondents. Determination of Sub-district locations selected six Sub-districts from 12 Subdistricts by purposive sampling with the largest number of Tamiang Tribe. The results showed that there were 225 species from 74 families used by the Tamiang people in treating various diseases. The most commonly cured diseases are fever, diabetes, and hypertension. Tagetes erecta is the most widely recognized medicinal plant species with a relative citation frequency index of 1.00. At the same time, Andrographis elongata is the most frequently used medicinal plant by the local community with a use value index of 1.00. In addition, local people identified the leaf organ (60.89%) as the most commonly used part of the plant, while decoction (58.20%) was the most popular method of administering traditional medicine. Both species of Andrographis elongata and Moringa oleifera have the potential to treat diabetes and hypertension as seen from the highest ICS value as prospective plants in the utilization and management of medicinal plants, so they can be developed as raw materials for herbal medicine.

Abstract

This study aims to analyze the distribution of vegetation density in Langsa City using the Normalized Difference Vegetation Index (NDVI). The research was conducted from June to October 2024, covering a study area of ​​21,881.41 ha. The method used is remote sensing, using Sentinel-2A satellite imagery, along with Geographic Information System (GIS) software, specifically ArcGIS, for mapping and spatial analysis. The NDVI classification results show five land cover categories based on NDVI value ranges. NDVI Class 1 (-0.38 to -0.02) includes non-vegetated land and water bodies. NDVI Class 2 (-0.02–0.20) indicates very low greenness, typically consisting of bare land. NDVI Class 3 (0.20–0.38) represents low greenness, which includes built-up areas. NDVI Class 4 (0.38–0.54) includes moderate greenness, typically found in plantations or fields, while NDVI Class 5 (0.54–0.83) represents high greenness, covering areas such as shrubs, forests, and mangroves. This analysis provides valuable information for land use planning and environmental management based on spatial vegetation data. The results of this study are expected to serve as a basis for policy-making that supports the sustainable management and conservation of vegetation in Langsa City.

Abstract

Abstract: The Great Argus (Argusianus argus) is a ground-dwelling pheasant species whose reproductive behavior is characterized by the establishment and maintenance of display courts used during courtship. Information on the distribution and habitat characteristics of these display courts remains limited, particularly in Sumatra. This study aimed to assess the distribution and characterize the habitat conditions associated with Great Argus display courts at the Soraya Research Station (SRS), Aceh, Indonesia. Field surveys were conducted from April to July 2024 to locate display courts and evaluate their surrounding habitat characteristics. Vegetation data were collected using 40 sampling plots (20 × 20 m) established around the identified display courts.A total of 10 display courts were recorded within an approximately 500-ha study area. Display courts were located at elevations ranging from 120 to 207 m above sea level and on slopes of 2–19°, indicating a preference for relatively flat to gently sloping terrain. The mean display court perimeter and area were 26.8 m and 58.07 m², respectively. Environmental conditions surrounding the display courts were characterized by a mean air temperature of 27.0°C, soil temperature of 27.3°C, light intensity of 378.4 cd, relative humidity of 76.5%, and soil pH of 6.6. Vegetation analysis revealed a high level of tree species diversity, with a Shannon–Wiener diversity index (H′) of 4.43. The highest Importance Value Index (IVI) values were recorded for Streblus elongatus and Artocarpus sp., indicating their dominance within the vegetation community surrounding several display courts. The occurrence of display courts in areas with high tree diversity and specific topographic conditions suggests that habitat structure may influence display court establishment by Great Argus. These findings provide important ecological information for understanding habitat requirements of the species and may contribute to the development of conservation and habitat management strategies for Great Argus populations in Aceh and other parts of Sumatra. Abstrak: Kuau raja (Argusianus argus) merupakan salah satu spesies burung dari famili Phasianidae yang memiliki perilaku unik berupa pembuatan arena kawin (display court) sebagai tempat untuk menarik pasangan selama musim reproduksi. Penelitian ini bertujuan untuk mengkaji sebaran dan karakteristik arena kawin kuau raja di Stasiun Penelitian Soraya (SPS), Aceh. Penelitian dilaksanakan pada April hingga Juli 2024. Metode yang digunakan meliputi metode jelajah untuk mengidentifikasi dan memetakan sebaran arena kawin serta metode purposive sampling untuk menganalisis vegetasi di sekitar arena kawin. Sebanyak 40 plot pengamatan berukuran 20 × 20 m ditempatkan di sekitar arena kawin yang ditemukan. Hasil penelitian menunjukkan bahwa terdapat 10 arena kawin yang tersebar pada area seluas sekitar 500 ha dengan kisaran ketinggian 120–207 m di atas permukaan laut dan kemiringan lereng 2–19°. Kuau raja cenderung membangun arena kawin pada lokasi dengan topografi datar hingga landai. Rata-rata keliling arena kawin mencapai 26,8 m dengan luas rata-rata 58,07 m². Kondisi lingkungan di sekitar arena kawin ditandai oleh suhu udara rata-rata 27,0°C, suhu tanah 27,3°C, intensitas cahaya 378,4 cd, kelembapan relatif 76,5%, dan pH tanah 6,6. Analisis vegetasi menunjukkan bahwa keanekaragaman jenis pohon di sekitar arena kawin tergolong tinggi, dengan nilai indeks keanekaragaman Shannon–Wiener (H') sebesar 4,43. Jenis pohon yang memiliki Indeks Nilai Penting (INP) tertinggi pada beberapa arena kawin adalah Damli (Streblus elongatus) dan Cempedak Air (Artocarpus sp.). Hasil penelitian menunjukkan bahwa keberadaan arena kawin kuau raja berkaitan erat dengan kondisi habitat, terutama struktur vegetasi dan karakteristik topografi. Temuan ini dapat menjadi dasar ilmiah dalam upaya konservasi dan pengelolaan habitat kuau raja, khususnya di Stasiun Penelitian Soraya, Aceh.
