Abstract. Dewi MAK, Aurina DM, Faturrahman AD, Fatikha LA, Rachmalia F, Ainaya FA, Kinanthi A, Rohman CM, Fadzilah FPA, Pramudita DA, Ramadhan MF, Mahajoeno E, Nugroho GD, Sujarta P, Dadiono MS, Yap CK, Rahim KABA, Setyawan AD. 2023. Ecological index and economic potential of mollusks (Gastropods and Bivalves) in Ayah Mangrove Forest, Kebumen District, Indonesia. Biodiversitas 24: 1231-1241. Mollusks are a group of triploblastic coelomates with soft bodies that live in various ecosystems, one of which is mangroves. This research was conducted with the aim of knowing the ecological index and economic potential in the mangrove forest of Ayah Village, Kebumen District, Central Java, Indonesia. First, the sampling method for each location using a transect plot measuring 10 x 10 m² was made. Mollusk species in each plot that had been obtained were then counted, collected, and recorded. Furthermore, abiotic variables such as water salinity, soil and water pH, and air, water and soil temperature, were measured. Then, the individuals and mollusk species that have been collected are calculated using ecological indices, such as the Shannon-Wiener biodiversity index, species density, Margalef species richness index, Evenness index, and Simpson dominance index. Meanwhile, the economic potential of the mollusk was searched using references from scientific journals and books. Finally, all data obtained were analyzed descriptively with supporting figures and tables. The results obtained 23 identified species of mollusk, i.e.: Gastropods (18 species) and Bivalves (5 species). The total density of mollusk obtained was 3.49 ind/m2, the species diversity index was 2.22 (moderate), the species evenness index was 0.71 (relatively even), the species dominant index was 0.16 (low), the species richness index was 2.71 (low). The environmental factors are as follow: temperature of air (30-30.3°C), water (28-29°C), soil/sediment (24-30°C), water pH 7.5-7.7, soil pH 7 and salinity 1-5 ppt. Of the total of 23 mollusks, 18 species could be consumed, i.e.: A. granosa, B. spirata, C. angulifera, C. aurisfelis, C. oualaniensis, E. aurisjudae, F. ater, L. scabra, N. lineata, N, violacea, N. dubia, P. viridis, P. cingulata, P. expansa, P. canaliculata, P. maculata, S. cucullata, and T. telescopium. The seven species of mollusks can be used as accessories, i.e.: B. spirata, N. lineata, P. cingulata, P. exilis, P. expansa, P. canaliculata, and P. maculata. Meanwhile, the mollusks used as decorations are as many as eleven, i.e.: A. granosa, B. spirata, C. corona, C. oualaniensis, N. margaritiferus, N. dubia, P. expansa, P. canaliculata, P. maculata, S. cucullata and V. turrita.

Abstract. Nurcahyo FD, Zen HM, ‘Azizah HPN, Nugroho GD, Ramdhun D, Yap CK, Indrawan M, Setyawan AD. 2024. The community structure of Echinodermata (Echinoidea and Holothuroidea) on seagrass ecosystem in Gunungkidul, Yogyakarta, Indonesia. Biodiversitas 25: 4561-4571. Echinoderms, which encompass various classes such as sea urchins and sea cucumbers, play a crucial role in marine ecosystems and contribute significantly to maintaining ecological balance. Therefore, this study was conducted to understand the composition structure of echinoderms (Echinoidea and Holothuroidea) in several beaches of Gunungkidul, Yogyakarta, Indonesia. The survey was conducted on March 2024 at Pringjono Beach, Dadap Ayam Beach, Ngrenehan Beach, Torohudan Beach, and Ngrawah Beach. Data analyzed included species diversity, density and ecological indices of echinoderms (Echinoidea and Holothuroidea) at each beach location. The research findings revealed that across the five beaches of Gunungkidul, Yogyakarta, Indonesia, there were two classes of echinoderms, namely Echinoidea (sea urchins) and Holothuroidea (sea cucumbers), with a total of 7 identified species, namely Echinometra mathaei, Echinometra oblonga, Heterocentrotus trigonarius, Tripneustes gratilla, Colobocentrotus atratus, Stomopneustes variolaris, and Holothuria leucospilota. Only one beach recorded the presence of sea cucumbers, while the number of sea urchin species varied at each beach. Dadap Ayam Beach recorded the highest number of sea urchin species, followed by Ngrenehan Beach. Additionally, Dadap Ayam Beach exhibited higher values of species diversity and richness compared to other beaches. A total of seven echinoderm species were identified, with a total abundance of 367 individuals/1000 m2. The beaches in this study showed variations in the diversity and distribution of echinoderms, particularly Echinoidea and Holothuroidea. However, overall species diversity and richness values were generally low, indicating the potential vulnerability of these ecosystems.
