| Judul Artikel | STUDI KOMUNITAS RUMPUT LAUT PADA BERBAGAI SUBSTRAT DI PERAIRAN PANTAI PERMISAN KABUPATEN CILACAP |
| Abstrak (Bhs. Indonesia) | Rumput laut di alam ada yang tumbuh pada substrat pasir, campuran antara pasir, lumpur dan pecahan cangkang karang serta pada substrat karang. Beberapa penelitian sebelumnya ada jenis-jenis rumput laut tertentu dapat tumbuh pada lebih dari satu macam substrat. Penelitian ini bertujuan untuk mengetahui komunitas yang meliputi keanekaragaman, dominansi, kemerataan dan kesamaan rumput laut pada berbagai substrat di pantai Permisan, Jawa Tengah. Penelitian ini menggunakan metode survai dengan teknik pengambilan sampel menggunakan metode kuadrat dengan plot berukuran 1 x 1 m2 secara acak terpilih pada masing – masing substrat. Berdasarkan hasil penelitian di Pantai Permisan Cilacap, Jawa tengah ditemukan rumput laut sebanyak 20 jenis dengan total biomassa sebesar 4,669g. Jenis rumput laut yang tumbuh pada substrat pasir sebanyak 7 jenis dengan biomassa sebesar 0,636g, substrat karang sebanyak 20 jenis dengan biomassa sebesar 2,399g dan substrat campuran sebanyak 12 jenis dengan biomassa sebesar 1,634g. Nilai indeks keanekaragaman di Pantai Permisan berkisar 0,064 - 0,828 dalam kriteria rendah. Nilai indeks dominansi berkisar antara 0,213-1,193 artinya terdapat jenis yang mendominansi. Nilai indeks kemerataan berkisar 0,021-0,276 artinya komunitas dalam kondisi labil. Nilai indeks kesamaan tertinggi terdapat pada substrat karang – campuran sebesar 75%.

| Abtrak (Bhs. Inggris) | Seaweed naturally grows in substrate of sand, mixing between sand, mud and shells fragment, and also coral. Some past researches stated that there were types of seaweed that able to grow in more than one substrate. This research aims to know the community such as diversity, domination, evenness, and similarity from seaweed on various substrates in Permisan beach, Central java. Survey was this research method by using quadrate with plot measurement of 1 x 1 m2 as sampling method and randomly selected for each substrate. The research found that 20 kinds of seaweeds with biomass for about 4.669g. 7 kinds of seaweeds that grow in sand substrate with biomass for about 0.636g, 20 kinds of seaweed in coral substrate with biomass for about 2.399g, and 12 kinds of seaweeds in mixing substrate with biomass for about 1.634g. Diversity index value in Permisan beach was ranging between 0.064 – 0.828 and categorized as low. Domination index value was ranging between 0.213 – 1.193, which means there was dominating variety. Evenness index value was ranging between 0.021 – 0.276, which means the community was unstable. The highest similarity index value was coral substrate – mixing for about 75%.
