AbstrakEchinodermata merupakan salah satu kelompok invertebrata yang memegang peranan penting, baik secara ekologi maupun ekonomi. Pengetahuan tentang organisme ini sangat dibutuhkan terkait dengan keberadaannya di alam yang semakin tergerus oleh pembangunan dan aktivitas manusia yang tidak ramah lingkungan. Penelitian ini bertujuan untuk mengetahui struktur komunitas Echinodermata di kawasan intertidal Gili Meno, Lombok Utara, yang dilakukan pada bulan April 2018 di 6 stasiun pengamatan yang tersebar di kawasan intertidal. Pengambilan data dilakukan dengan metode belt transect dengan pengulangan sebanyak 2–4 kali pada setiap stasiun, dengan luas transek 100 m2. Hasil pengamatan menunjukkan bahwa ditemukan 13 spesies yang berasal dari 4 kelas Echinodermata, yaitu Asteroidea (1 spesies), Echinoidea (4 spesies), Holothuroidea (4 spesies), dan Ophiuroidea (4 spesies). Hasil penghitungan indeks ekologi menunjukkan bahwa indeks keanekaragaman komunitas Echinodermata berkisar antara 0,16–1,36 (kategori rendah-sedang). Indeks dominansi di setiap stasiun berkisar antara 0,32–0,94 (kategori rendah-sedang), sedangkan indeks kemerataan sebesar 0,25 (kategori rendah). Hal ini menunjukkan bahwa stabilitas komunitas Echinodermata di kawasan intertidal Gili Meno tergolong rendah. Hasil penelitian ini diharapkan dapat menjadi acuan dalam pembangunan kawasan wisata yang ramah lingkungan tanpa mengabaikan keberadaan sumber daya hayati laut di kawasan Gili Meno, Lombok Utara.Abstract Echinoderms are one group of invertebrates that play an essential role, both ecologically and economically. Knowledge about this organism is needed concerning its presence in nature, which increasingly eroded by the development and activities of people who are not environmental friendly. This study aims to determine the structure of the Echinoderms community in the intertidal area of Gili Meno, North Lombok, were conducted on April 2018 at six observation stations. Data were collected by belt transect method with repetition of 2–4 times at each station, with 100 m2 transect area.  The observations showed that found 13 species included in 4 classes of Echinoderms, namely Asteroidea (1 species), Echinoidea (4 species), Holothuroidea (4 species) and Ophiuroidea (4 species). The ecological index of the Echinoderms community showed that the diversity index ranged from 0.16–1.36 (low-medium). The dominance index at each station ranged from 0.32 to 0.94 (low-medium), while the evenness index was 0.25 (low). The stability of the Echinoderms community in Gili Meno intertidal area relatively low.

Apriadi T, Pratama G, Putra RD, Jumsurizal, Jaya YV, Firdaus M, Arpas HD, Suryanti A. 2018. Comparative study on the fish diversity from natural and bauxite post-mining in wetland system of Bintan Island, Indonesia. Biodiversitas 19: 967-973. In this study, the fish populations between two different wetland systems in Bintan Island, Indonesia, i.e., bauxite post-mining (Kijang) and natural wetland (Toapaya) were compared and to propose a newly index namely Environomic of Fishes Index (EFI) to their respective ecosystems. The purposive random sampling at six stations, each of three stations representing bauxite mining (Kijang) and three stations representing a natural wetland (Toapaya) were used in this research. The numbers of fish species and the abundance were enumerated. The new index derived from the value of diversity index (Shannon), similarity index (Evenness), dominance index (Simpson's), conservation status, and economic value were also evaluated. The natural wetland has higher fish diversity than bauxite post-mining. The total species found were twenty-four. The same seven species were found in both areas. Twelve species were obtained from bauxite post-mining, and nineteen species were obtained from natural wetland. Puntius tetrazona and Rasbora heteromorpha were the common species in area study. The diversity and dominance index was at low category, Evenness index was at high category in all stations, except in tidal swamp station at bauxite post-mining. The EFI in natural wetland was higher than bauxite post-mining. The three community index value, economic value, and conservation status of natural wetland were higher than bauxite post-mining.
