Kepiting bakau (Scylla serrata Forsskål, 1775) merupakan salah satu hewan yang
berhabitat asli di hutan mangrove dan mempunyai wilayah penyebaran yang cukup luas.
Aceh Barat Daya memiliki potensi ekosistem mangrove dan terumbu karang yang baik
sebagai tempat keberlangsungan hidup berbagai jenis hewan. Penelitian bertujuan
mengetahui karakteristik habitat breeding sites kepiting bakau di kawasan Gampong
Lama Tuha Kecamatan Kuala Batee Kabupaten Aceh Barat Daya. Metode yang
digunakan dalam penelitian adalah pendekatan deskriptif kualitatif dengan jenis
penelitian survei dengan teknik purposive sampling. Data yang diperoleh dianalisis secara
deskriptif dan disajikan dalam bentuk tabel. Hasil penelitian diperoleh data pH air
berkisar 7,4-7,6, pH tanah 5,1-5,3, suhu air berkisar antara 30-35°C, salinitas air berkisar
15-18 ppt, kedalaman air berkisar 110 cm-115 cm, kecepatan arus berkisar 0,1 m/detik0,2 m/detik, kecerahan air berkisar 80-85 cm. Substrat tergolong lempung berpasir dan
pasir berlempung. Terdapat beragam jenis flora dan fauna di kawasan tersebut.
Kesimpulan yaitu karakteristik habitat breeding sites kepiting bakau di kawasan
mangrove Gampong Lama Tuha Kecamatan Kuala Batee Kabupaten Aceh Barat Daya
tergolong baik sebagai tempat breeding sites kepiting bakau. Perlu adanya upaya dalam
menjaga kelestarian kualitas lingkungan.

The mangrove crab (Scylla serrata Forsskål, 1775) is one of the animals that Its original habitat is in mangrove forests and has a fairly wide distribution area. Southwest Aceh has the potential for good mangrove and coral reef ecosystems as a place for the survival of various types of animals. Purposeful research determine the habitat characteristics of mangrove crab breeding sites in the Gampong area Lama Tuha, Kuala Batee District, Southwest Aceh Regency. The method used in the research is a qualitative descriptive approach with types survey research with purposive sampling technique. The data obtained was analyzed sequentially descriptive and presented in table form. The results of the research obtained water pH data ranges from 7.4-7.6, soil pH 5.1-5.3, water temperature ranges from 30-35°C, water salinity ranges from 15-18 ppt, water depth ranges from 110 cm-115 cm, current speed ranges from 0.1 m/sec to 0.2 m/sec, water brightness ranges from 80-85 cm. The substrate is classified as sandy loam and clayey sand. There are various types of flora and fauna in the area. The conclusion is the habitat characteristics of mud crab breeding sites in the area Gampong Lama Tuha mangrove, Kuala Batee District, Southwest Aceh Regency classified as a good breeding site for mangrove crabs. Inner efforts are needed maintain environmental quality sustainability. Key words: breeding sites, mangrove crabs, mangrove ecosystem
