Abstract. Muzaki FK, Setiawan E, Insany GFA, Dewi NK, Subagio IB. 2019. Community structure of Echinoderms in seagrass beds of Pacitan beaches, East Java, Indonesia. Biodiversitas 20: 1787-1793. In this study, we attempt to access diversity and community structure of Echinoderms on seagrass beds in each three belt transect (width 2 m, length 100 m) in Tawang and Pidakan beaches, Pacitan, East Java, Java. Observed parameters were species richness, composition, and abundance, as well as diversity indices: Shannon-Wiener's diversity index (H'), Simpson's dominance index (D) and Pielou's evenness index (J). At the end of the study, we identified one species of sea star (Asteroidea), seven species of brittle stars (Ophiuroidea), ten species of sea cucumbers (Holothuroidea) andnine species of sea urchins (Echinoidea). The most dominant species were Ophiocoma dentata (F. Ophiocomidae), Diadema setosum (F. Diadematiidae), Ophiomastix annulosa (F. Ophiocomidae) and Echinometra mathaei (F. Echinometridae). Value of H’ ranged from 0.538 to 1.252 in Tawang and 1.041 to 1.704 in Pidakan; which showing higher species richness and diversity in Pidakan. Echinoderm in the study area was not evenly distributed; D. setosum was very dominant in Tawang beach, while those three other species were more common in Pidakan. Furthermore, most of Holothuroid and Ophiuroid were found only in Pidakan which have relatively more complex habitat.

Abstract

Abstract. Authors. 2019. The activity phagocytosis of isoeugenol-ester compound on Mus musculus macrophage cell. Nusantara Bioscience 11: 117-122. Chemotherapy is drugs therapy for cancer. However, chemotherapy could damage normal cells and decrease immune system. For this reason, it is necessary to find immunostimulant compound that is able to increase immune system. Isoeugenol-ester is unnatural compound that has been tested for its cytotoxicity against cancer cell and showed positive result. Nevertheless, ability of Isoeugenol-ester for inducing phagocytosis is still unknown. Therefore, bioassays study using in vitro phagocytosis were performed. Latex beads methods using antigen model in 5 isoeugenol-ester concentration series: 6, 25; 12, 5; 25; 50 and 100 ?g/mL were tested to Mus musculus peritoneal macrophage cell. The optimum concentration of Isoeugenol-ester compounds in inducing phagocytosis activity of M. musculus macrophage cell was 12.5 ?g/mL.
