"Napoleon fish (Cheilinus undulatus) is one of wrasses that has a high value in the worlds market. This paper present the existence of Napoleon fish of Maratua Island, East Borneo as one of its habitat in Indonesia and current records influencing the social-economic conditions there. The existence of Napoleon fish were detected by GPS (Global Positioning System) using Density Survey Method at six station of three different island i.e. Maratua, Kakaban, and Atol of Karang Muaras. During the observation, four Napoleon fish were found successfully in the northern coastal area of Kakaban Island. Unsustainable fishing activities such as using the potassium cyanide, fish bomb, and illegal fishing suggested as reasons of dramatic declining in the fishery production"

"Fishes are an economical and healthy source of protein for the majority of the world community. However the concentration of mercury in fish due to anthropogenic emissions pose health risks to humans. The concentration of organic mercury (methylmercury) dominates 80-90 persen total mercury concentrations in fish flesh. The Accumulation of mercury increases with the rise of water temperature, organism age, time of exposure, and the concentration of protein- bound mercury. The decline in salinity or hardness, pH, organic matter content, and the presence of Zn, Cd, or Se in solution will also increases the accumulation of mercury. The rate of accumulation of methylmercury in fish affects the toxicity, in which a low rate of accumulation associates with a higher tolerance. "

"The japanese threadfin bream, Nemipterus japonicus is one of demersal fishes of the Family Nemipteridae which has high economy value and commonly caught by bottom trawl. The distribution is widespread throughout the Indian Ocean and West Pacific. This species is commonly found in coastal waters, on muddy or sandy bottoms from 5 to 80 meters depth. Special characteristics of N. japonicus are having 11-12 pale golden-yellow stripes along the body from behind of the head to the base of caudal fin, a prominent red-suffused yellow blotch origin of lateral line and a yellow fillament on caudal fin. This species is carnivorous and has external reproductive system. The diet consists mainly of small fishes, molluscas, crustaceans (mainly crab or shrimp), polychaetes and enchinoderms."

"ABSTRACt
Bintan is one of the remarkable islands in Indonesia. The fertile soil, the abundant of water sources throughout the year; the various and numerous mineral resources and the beauty that dazzles with white sandy beach are several of the magic. Bauxite is the other magic of the island, since this mineral is the main mine resource of this island. This article explores the huge potency of alumina and the threat of mining activities in Bintan Island, especially in Gunung Kijang District which located in the eastern part of the main island."

"ABSTRACT
Lombok is located between Bali and Sumbawa Island. This island is popular as tourist destination, especially for marine tourism. On the other hand, marine fauna from Lombok is not so popular as their beautiful beaches. One kind of marine fauna is snail, neriti snails are common and easy to find along the beach. T here are twelve species of Nerita snails found in Lombok recently. Nine 0fthem were having their representations in the collections of Museum Zoology Bogor; while the rest three are not yet collected. One of museum collection, Nerita acellata Le Guillou, 1841, is never reported from Lombok before."

"Synaptidae was one of holothuroidea member, unique because they has no podia or tube feet in their surface of body wall and has no respiratory trees in their internal organ. They has anchor shape spicules in their body wall that supporting locomotory function. Synaptidae were frequently found in the sea grass area, but no publication was specifically observed their existence. This study proposed to observed the species of synaptidae in Sanur Beach-Bali, included their length distribution and their vegetation preference to live with. The observation was conducted twice time using swept survey time based method (one hour) on low tide. The results shows 46 individual of synaptidae consist of two species (Synapta maculata and Opheodesoma grisea) found in the intertidal zone of Sanur Beach-Bali. In the first observation, most of synaptidae had shorter body length then in the second observation. Almost all of synaptidae observed was associated with Enhalus acoroides. Synaptidae in the study area adapt to a very extrem environment. Their adaptation were: 1) osmoregulation to the fluctuation of salinity; 2) wide tolerance of temperature fluctuation; defense mechanism to the wave motion by 3) having sticky skin and 4) autotomy mechanism.

"MANFAAT KITIN DAN KITOSAN BAGI KEHIDUPAN MANUSIA. Udang dan kepiting merupakan salah satu komoditi ekspor non migas yang menghasilkan limbah berbentuk cangkang dan dapat dimanfaatkan dalam pembuatan kitin dan kitosan. Kitin merupakan komponen utama dari eksoskeleton invertebrata, krustase dan insekta dimana komponen ini berfungsi sebagai komponen penyokong dan pelindung. Sedangkan kitosan merupakan polimer alamiah yang sangat melimpah keberadaannya di alam sehingga merupakan bahan perdagangan yang memiliki nilai ekonomi tinggi dan dapat dimanfaatkan bagi kehidupan manusia. Kitin dan kitosan memiliki kegunaan yang sangat luas dalam kehidupan sehari-hari misalnya sebagai adsorben limbah logam berat dan zat warna, pengawet, anti jamur, kosmetik, farmasi, flokulan, anti kanker, dan anti bakteri.Tulisan ini mencoba memberikan gambaran dan informasi bahwa limbah kulit udang dapat dijadikan kitin dan kitosan yang sangat bermanfaat bagi kehidupan manusia.

"Pollen grains and spores are an object which studied in palynology. Pollen is produced by seed plants which include gymnosperms and angiosperms. Pollen grains are male reproductive organ of seed plants. Meanwhile, spore is produced by cryptograms which include ferns and Mosses. Cryptogram spores being a resting and dispersal phase in gametophyte. In the study of pollen grains and spores, the complexity of their structure and patterning has necessitated a specific terminology. The main characters of pollen and spores are unit, shape, aperture, and sculpture. They are an important and valuable iriformation in palynology, so their applications relates to other knowledge such as geochronology, biostratigraphy, climate change, migration, flora evolution, stratigraphy, paleoecology, paleoclimatology and archeology"
