Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Indonesia is particularly rich in Echinoderms and North Sulawesi lies at the geographic centre of this biodiverseÂ marine realm. While further studies on Sulawesi Echinodermata are required in order to obtain full understanding ofcurrent biodiversity status, preliminary SCUBA and intertidal surveys in early 2012 in the vicinity of the LembehÂ Island, a region little explored previously, recorded a total of 76 species of 4 classes (Asteroidea, Ophiuroidea,Â Echinoidea and Holothuroidea) from shallow waters (0-40 m) at 36 sites (sea grass, coral rubble and reef). TheÂ class Crinoidea is not reported here. A review of Echinoderm literature for North Sulawesi noted that there are 114Â species belonging to 5 classes of Echinodermata.

Bangka Island is well known as the worldâ??s largest tin producer. The inland and offshore tin mining hasÂ profound effects on the coastal environment, resulting in the high sedimentation in the water. Many corals sufferedÂ physiological damage due to low light intensity. The distribution of stony corals and the status of coral reefs wasÂ surveyed at 6 sites in West Bangka waters in October 2012. A total of 72 species of corals belonging to 33 generaÂ and 12 families were found, and 4 species were distributed at all research sites. The live coral coverage was 36% on average and was categorized as being in fair condition. The coverage was 0% at Kamboja Island where the coralsÂ were the most affected by tin mining. The sediment flowed out from tin mining, blocked the light, and settled onÂ the coralsâ?? surface. Consequently, many corals were buried and the live corals decreased. It is obviously necessaryÂ to reduce and control the tin mining.

Providing accurate information on suitable multispectral satellite sensors for mapping coral reefs in Indonesia is a challenge for coastal remote-sensing experts. As coral reefs vary in spatial extent, shape, length, perimeter and/or distance to shore, the mapping of coral reefs will need different satellite sensors depending on the objectivesÂ and the kind of information required. This work compares the suitability of two kinds of multispectral satelliteÂ sensors for mapping coral reefs in Indonesia, high and moderate spatial resolution. This was done through a caseÂ study of Wakatobi Marine National Park since that represents many types of coral reef in Indonesia (fringing,Â barrier, atoll, and patch). Indonesian coral reef shapefile data 2010 was downloaded from UNEP (United NationsÂ Environment Programme) website, and Landsat 7 ETM + images, path/row 112/064 was used to determine theÂ terrestrial area of Wakatobi Islands. Both high and moderate spatial resolution sensors are suitable for mapping theÂ benthic communities and geomorphic zones on coral reefs. The former are more accurate but they are also muchÂ less cost-effective, especially over large areas.

Three specimens of Plectranthias retrofasciatus Fourmanoir and Randall, 1979 and one specimen of P. randalliÂ Fourmanoir and Rivaton, 1980 were collected by first author from fish market, Bitung, North Sulawesi on JuneÂ and September 2010. The specimens were deposited at LBRC-F, the reference collection of LIPI Bitung, TechnicalÂ Implementation Unit for Marine Biota Conservation, Research Centre for Oceanography, Indonesian Institute ofÂ Sciences, Bitung, Indonesia. Plectranthias retrofasciatus is closely related to P. megalophthalmus and P. knappi,Â in sharing some morphological characters as snout length and interorbital width, while P. randalli differs to otherÂ species by having a moderate deep body proportion. Initially these species known only from New Caledonia for P.Â retrofasciatus and Chesterfield Islands and southern Taiwan for P. randalli respectively. The two species of anthiineÂ fishes collected from Bitung, Indonesia bringing the total number of species of this genus known in Indonesia to six.

Volcanic activities have inï¬? uenced the Cisanggarung estuary in western Cirebon Regency, altering metalÂ concentrations in the bottom sediment. Observation of metal content in the ocean there was carried out in AugustÂ 2009. Sediment samples were collected at 16 stations along the Cisanggarung coastline. The aim of this work wasÂ to determine the spatial distribution of Cd, Cu, Pb and Zn in the sediment of the Cisanggarung estuary. SedimentÂ was destructed using 3 acids: nitric acid, chloride acid and peroxide acid, which was then analyzed by Flame AtomicÂ Absorption Spectrophotometry based on the US EPA 3050b method. The highest concentrations of Cd, Cu, Pb andÂ Zn in the sediment were 0.73 mg/kg dry weight, 31.4 mg/kg dry weight, 23.9 mg/kg dry weight and 143 mg/kg dryÂ weight, respectively. The metals in the sediment had accumulated near the shoreline, up to ï¬ ve kilometers awayÂ from the river mouth, indicating that terrestrial area and sediment fractions inï¬? uenced their distribution.

EFFECT OF VARIOUS DIETARY SEAWEEDS ON THE GROWTH OF GOLD-MOUTH TURBAN (Turbo chrysostomus L., 1758) AT LOMBOK, INDONESIA Ridwanudin, Asep; Firdaus, Muhammad; Pratama, Idham Sumarto; Dwiono, Sigit Anggoro Putro

Gold-mouth turban (Turbo chrysostomus L., 1758) is an important source of protein for coastal people in Lombok, West Nusa Tenggara, Indonesia. In order to acquire its seed production technique, research on the culture of the species was carried out since 2012. Feed source is a key concern when culturing animal, including turban snail. Growth of gold-mouth turban fed with seaweed Gracilaria sp., Ulva spp., and Kappaphycus alvarezii was evaluated. Each diet was randomly assigned to triplicate groups of 30 snail juveniles with an initial body weight and shell length of 4.65 ± 0.00 g and 24.55 ± 0.08 mm, respectively. After six weeks feeding trial, snails fed with Gracilaria sp. diet had significantly higher (P < 0.05) in final weight, final shell length, weight gain, specific growth rate (SGR) and food intake compared to snails fed with Ulva spp. or K. alvarezii diets.

To compensate the decline of the populations of temperate anguillid eels, tropical anguillid eels become getting attention of East Asian eel market in recent years. Many eel farms have been established in Java Island to culture tropical anguillid eels intending to export the products to East Asia. Since eel farming is reliant on wild-caught anguillid eels such as glass eels, elvers and yellow eels, these eel seeds have been captured in various places in Indonesia. However, it is still unknown that how much of tropical anguillid eels are caught as seeds for eel farming. This study showed two different patterns of the commodity chains of eel seeds from both Sukabumi Regency and Bengkulu Province to the eel farms in Java Island. Official catch statistics on anguillid eels found in both Sukabumi Regency and Bengkulu Province were also analyzed on their features and problems underlied. Considering the sustainable use of anguillid eel resources and critical stances on exploitation of eel seeds from all over the world, the Indonesian government should take an immediate action for developing the national catch statistics on anguillid eel fishery as soon as possible.

Indonesia is situated in the Coral Triangle region that has the world?s highest coral reef biodiversity. Therefore, coral reef monitoring needs to be conducted regularly to assess the condition of coral reef ecosystem for management purpose. There are several coral reef monitoring methods available such as the line intercept transect (LIT), point intercept transect (PIT), photo transect, belt transect and benthic towed-diver. In Indonesia, LIT and PIT are the most commonly used methods for coral monitoring. However, there is a main disadvantage when collecting data using these methods, that is scientific divers need to spend hours to input the data after dives. Here, we introduce an electronic logging instrument called Coral Input Data Instrument that helps to decrease the input data time by employing a look-up table system that simplifies data input process by replacing text with numerical coding. In addition, water quality data such as temperature, depth and visibility also are embedded in the electronic logging instrument. The instrument hardware consists of Arduino Mega 2560, keypad 4x3, LCD Module 16x2 character, real time clock, temperature sensor, pressure sensor, visibility sensor and micro SD card module. Arduino IDE 1.6.5 software is used to program the microcontroller. In this paper, we describe the design and implementation of the instrument in the field.

Indonesia was recently ranked second on the list of countries producing plastic waste. Plastic can be degraded by thermal oxidation either with ultraviolet radiation and by mechanical to a very small size the size will be smaller. Degraded plastic with small sizes (<5 mm) measured has been micrometers known as microplastic. We took sediment samples on 07-18 May 2015 in EWIN 2015 cruise, which part of the contribution of Indonesian researchers for the International Indian Ocean Expedition-2 program, at 66.8 to 2182 m below sea level. Microplastic analysis from the sediment was carried out by using flotation methods. We found microplastic in 8 locations out of 10 sampling locations. We found 41 particles microplastic with a form of granules (35 particles) and fibers (6 particles). Most of microplastic particles were found at depths less than 500 m with 20 particles. The discovery of microplastic in the sediment from the sea of western Sumatra at a depth more than 2000 m, indicated that plastic, considered new developed materials (early nineteen centuries made), has invaded marine areas, including pristine areas. It confirms the statement that plastic waste has spread widely to different areas of the seas and oceans, including remote and mostly unknown areas such as the deep sea.
