| Abstrak (Bhs. Indonesia) | Ekosistem hutan mangrove di Segara Anakan Cilacap mempunyai peranan ekologis yang sangat penting bagi beberapa biota akuatik diantaranya gastropoda. Penelitian berjudul “Hubungan Kerapatan Mangrove Dengan Kelimpahan dan Keanekaragaman Gastropoda di Segara Anakan Bagian Timur Cilacap” bertujuan untuk mengetahui kerapatan mangrove, kelimpahan dan keanekaragaman gastropoda, serta hubungan antara kerapatan mangrove dengan kelimpahan dan keanekaragaman gastropoda. Metode penelitian yang digunakan adalah metode purposive random sampling, pengambilan sampel gastropoda menggunakan metode transek kuadrat. Analisis data dilakukan secara deskriptif. Hasil penelitian menunjukkan bahwa kerapatan mangrove di perairan Segara Anakan Timur, Cilacap sebesar 144,44 – 2.933 ind/ha yang termasuk dalam kategori jarang sampai rapat. Kelimpahan Gastropoda berkisar antara 13,8 – 22,4 ind/m2. Keanekaragaman (H’) termasuk dalam kategori sedang (1,949 – 2,177). Terdapat hubungan yang sangat kuat antara kerapatan mangrove dengan kelimpahan gastropoda dan terdapat hubungan yang kuat antara kerapatan mangrove dengan keanekaragaman gasrtropoda. |

| Abtrak (Bhs. Inggris) | The mangrove ecosystem in Segara Anakan Cilacap has an important ecological role for aquatic organisms such as gastropods. The research entitled “The Relation Between Mangrove Density With Abundance and Diversity of Gastropods in Eastern part of Segara Anakan Cilacap” aims to determine the density of mangroves, the abundance and diversity of gastropods, and the relation between the density of mangrove with the abundance and diversity of gastropods in the eastern part of Segara Anakan, Cilacap. The research method used purposive random sampling, gastropods samples were taken by the quadratic transect method. The data was analysed by descriptive technique. The results showed that the average density of mangroves in the eastern part of Segara Anakan water, Cilacap was dense with density between 144.44 – 2,933 ind/ha. Gastropods abundance ranges from 13.8 – 22.4 ind / m2. Diversity (H') was moderate diversity with value between 1.949 – 2.177. The mangrove density had very strong relation with abundance of gastropods and had strong relation with diversity of gastropods. |
