Kepiting bakau (Scylla sp) merupakan komoditas bernilai ekonomis tinggi yang keberlangsungan hidupnya sangat bergantung pada kualitas ekosistem mangrove. Penelitian ini bertujuan untuk mengetahui karakteristik biotik (meliputi fauna dan vegetasi mangrove) dan abotik (meliputi salinitas air, suhu air, pH air, pH tanah dan substrat sarang) habitat kepiting bakau (Scylla sp) di ekosistem mangrove Kecamatan Pidie. Penelitian dilakukan pada bulan September 2025. Pengambilan data vegetasi menggunakan metode transek garis berpetak (line transect plot) dengan ukuran plot 10 m x 10 m. Lokasi dibagi menjadi dua stasiun, yaitu Stasiun I (ekosistem mangrove dekat pemukiman) dan Stasiun II (ekosistem mangrove jauh dari pemukiman). Penentuan tipe substrat menggunakan analisis fraksi sedimen Segitiga Miller. Parameter penelitian ini meliputi suhu air (Co), salinitas air (ppt), pH air, pH tanah, substrat sarang, fauna dan vegetasi mangrove. Hasil penelitian menunjukkan bahwa parameter fisika kimia perairan di kedua stasiun masih dalam kisaran toleransi kehidupan kepiting bakau (suhu 26°C 32°C, pH 6,0 7,5). Kondisi salinitas Stasiun I lebih payau (20 ppt) dibandingkan Stasiun II (30 ppt). Spesies fauna perairan dari 8 familia yang berbeda, di antaranya berasal dari familia Oxudercidae, Diogenidae, Ostreidae, Corbiculidae, Dotillidae, Ocypodidae, Alpheidae, dan Ardeidae. Vegetasi mangrove terdiri dari 4 spesies, yaitu Rhizophora apiculata, Rhizophora mucronata, Nypa fruticens dan Sonneratia alba, sehingga dapat disimpulkan bahwa, karakteristik habitat kepiting bakau (Scylla sp) di ekosistem mangrove Kecamatan Pidie ditentukan oleh sinergi antara faktor biotik dan abiotik yang saling mendukung. Kondisi lingkungan perairan berada dalam rentang toleransi optimal.

Arief Julianda. (2026). Identification of Habitat Characteristics of Mangrove Crab (Scylla sp) in the Mangrove Ecosystem of Pidie District, Pidie Regency, Aceh. [Script. Universitas Syiah Kuala]. Under direction of Dra. Asiah MD., M.P and Wardiah, S.Pd., M.Bio. Mangrove crab (Scylla sp) is a high economic value commodity whose survival is highly dependent on the quality of the mangrove ecosystem. The study aims to determine the biotic characteristics (including mangrove fauna and vegetation) and abiotic (including water salinity, water temperature, water pH, soil pH and nest substrate) of the mangrove crab (Scylla sp) habitat in the mangrove ecosystem of Pidie District. The study was conducted in September 2025. Vegetation data collection used the line transect plot method with a plot size of 10 m x 10 m. The location was divided into two stations, namely Station I (mangrove ecosystem near settlements) and Station II (mangrove ecosystem far from settlements). Determination of substrate type used Miller's Triangle sediment fraction analysis. The parameters of this study included water temperature (Co), water salinity (ppt), water pH, soil pH, nest substrate, fauna and mangrove vegetation. The results of the study indicate that the physicochemical parameters of the waters at both stations are still within the tolerance range of mangrove crab life (temperature 26°C 32°C, pH 6.0 7.5). The salinity conditions of Station I are brackish (20 ppt) compared to Station II (30 ppt). Aquatic fauna species from 8 different families, including those from the Oxudercidae, Diogenidae, Ostreidae, Corbiculidae, Dotillidae, Ocypodidae, Alpheidae, and Ardeidae families. Mangrove vegetation consists of 4 species, namely Rhizophora apiculata, Rhizophora mucronata, Nypa fruticens and Sonneratia alba, so it can be concluded that the characteristics of the mangrove crab (Scylla sp) habitat in the mangrove ecosystem of Pidie District are determined by the synergy between biotic and abiotic factors that support each other. The condition of the aquatic environment is within the optimal tolerance range. Keywords: Scylla sp, Mangrove, Habitat, Substrate, Pidie district
