Abstract

Penelitian ekhinodermata di perairan pantai Gunung Kidul dilakukan pada bulan Maret 2012 di lima lokasi yaitu : Pantai Kukup, Pantai Krakal, Pantai Drini, Pantai Sepanjang dan Pantai Sundak. Penelitian ini bertujuan untuk menggali informasi struktur komunitas ekhinodermata di perairan pantai Gunung Kidul. Pengambilan contoh biota dilakukan dengan menggunakan transek kuadrat ukuran 1m x 1m. Dari hasil penelitian diperoleh 12 jenis fauna ekhinodermata yang mewakili empat jenis Holothuroidea, empat jenis Echinoidea, dan empat jenis Ophiuroidea. Kelompok bintang mengular atau Ophiuroidea merupakan kelompok yang paling menonjol untuk daerah karang mati. Berdasarkan hasil transek yang dilakukan di lima lokasi yang diamati, ternyata bahwa kelompok bulu babi (Echinoidea) menempati tingkat kekayaan jenis relatif tinggi. Dari analisa kuantitatif diperoleh nilai indeks keanekaragaman dan indeks kemerataan tertinggi ditemukan di Pantai Kukup (H = 0,996; J = 0,896) dan nilai indeks kekayaan jenis tertinggi didapatkan pada Pantai Sundak (D = 0,185). Terlihat umumnya kelompok biota menyukai mikrohabitat lamun (10 jenis), tujuh jenis menempati mikrohabitat pasir dan lima jenis menempati mikrohabitat karang mati. Analisis hierarki dilakukan untuk mengetahui pola pengelompokan jenis di setiap lokasi disarikan pada indeks kemiripan.

Abstract

Penelitian Ekhinodermata di perairan Lombok telah dilakukan pada bulan Juli 2010 di tiga lokasi yaitu: Tanjung Kayangan, Medana dan Penyabuan. Penelitian ini bertujuan untuk menggali informasi kehadiran ekhinodermata di perairan Lombok, Nusa Tenggara Barat. Pengambilan contoh biota dilakukan dengan menggunakan transek kuadrat ukuran 1m x 1m. Dari hasil penelitian di peroleh 16 jenis fauna ekhinodermata yang mewakili empat jenis Holothuroidea, lima jenis Echinoidea, tiga jenis Asteroidea dan empat jenis Ophiuroidea. Kelompok bulu babi atau Echinoidea merupakan kelompok yang paling menonjol untuk daerah lamun. Berdasarkan hasil transek yang dilakukan di empat lokasi yang diamati, ternyata bahwa kelompok bulu babi (Echinoidea) menempati tingkat kekayaan jenis relatif tinggi. Dari analisa kuantitatif diperoleh nilai indeks diversitas tertinggi ditemukan di lokasi Medana (H = 1,02), nilai indeks kemerataan tertinggi terdapat pada lokasi Penyabuan (J = 0,99) dan nilai indeks kekayaan jenis tertinggi didapatkan pada Penyabuan (D = 0,21). Secara umum baik dalam jumlah jenis ataupun jumlah individu, fauna Ekhinodermata di perairan Lombok, Nusa Tenggara Barat lebih miskin bila dibandingkan dengan di perairan Derawan, Kalimatan Timur.

Abstract

Observation on sea cucumber diversity was carried out at coastal waters of Sudak and Nanggu Islands in the West Part of Sekotong Island, April and June  2002. Sampling was done by using a transect quadrant of 1 m x 1 m. This sampling and observation on its microhabitat were conducted by scuba diving. Analyses on the sea cucumber community structure were based on its frequency of occurance, diversity, and density. The results showed that at both locations  11 species of sea cucumber were found where  Holothuria scabra, H.atra, H nobilis, and Bohadschia marmorata  were predominant, common and more evenly distributed than the other species.

Abstract

Observation on echinoderms diversity was carried out at coastal waters of North Minahasa bay, North Sulawesi, from June to August 2008. Sampling was done by using a transect quadrant of 1 m x 1 m. The results showed that in both locations, 28 species of echinoderms represented 7 species of Holothuroidea, 9 species of Echinoidea, 6 species of Asteroidea and 6 species of Ophiuroidea had been found in the North Minahasa Bay, North Sulawesi. The Echinoidea were relatively common in the sea grass zone. On the basis of population density, Echinoidea was the dominant group and had the highest density. This research was aimed to find out the species composition, community structure, zonation, and spatial distribution of echinoderm fauna.

Abstract

Biodiversity of Echinoderms at Kuta Bay, West Nusa Tenggara. Observation on echinoderms diversity was carried out at coastal waters of Kuta bay in the Nusa Tenggara Barat, Nopember 2005. A total of 21 species of echinoderms, consist of 4 species Holothuroidea, 7 species Echinoidea, 5 species Asteroidea and 5 species Ophiuroidea have been found in the Kuta of Nusa Tenggara Barat. The Echinoidea were relatively common in the sea gras zone. On the basis of population density, Echinoidea was the dominant group and relatively highest in the individual density. In general the number of species of echinoderm fauna is smaller than in the Sekotong Lombok Barat Bay.

Abstract

Echinoderm Biodiversity in the Takofi Coastal Waters, Moti Island, North Maluku. A total of 22 echinoderm species were found in Takofi waters, North Maluku. They were represented by 6 species of holothuroidea, 4 species of asteroidea, 5 species of echinoidea and 7 species of ophiuroidea. The Ophiuroidea were relatively common in seagrass area. The quantitative analysis on the abundance data revealed the highest diversity index of faunal assemblage at station II (H’=1.19). The highest evenness index was exhibited by the echinoderms from station III (J = 0.99), while the highest species richness was represented by them from station I (D = 1.22).

Abstract

Holothurian (Holothuroidea) Community Structure in Some Coastal Waters of Kai Besar Island, South-East Maluku. During October and November 1990 the holothurian community inhabiting littoral areas was assessed at five locations : Borang, Ohoiwait, Nuwahan, Wahadan and Kurit Wur. This involved five ecological indices: density, species richness, diversity, evenness and similarity. It was revealed that the holothurian community consisted of 14 species in which five among them occurred in all locations at higher densities: Holothuria edulis, H. scabra, H. nobilis, H. atra and Stichopus chloronatus. Small variations of the ecological indices at all locations may indicate that the community characteristics at the five locations were relatively similar.

Abstract

Sea Cucumber Resources At Tanjung Pai Waters Padaido Biak Numfor Papua. Observation on sea cucumber diversity was carried out at coastal waters of Pai and Imbeyomi Islands in the Padaido Island Biak Numfor. Sampling was done by using a transect quadrant of 1 m x 1 m. This sampling and observation on its microhabitat were conducted by snorkling. Analyses on the sea cucumber community structure were based on its frequency of occurance, diversity, and density. The results showed that at both locations 10 species of sea cucumber were found where Holothuria edulis, H. atra, and H. nobilis were predominant common and more evenly distributed than the other species.
