Abstract

The metabolites from microorganisms are a rapidly growing field, due to the suspicion that a number of metabolites obtained from reefs invertebrates are produced by associated microorganisms. Less than 2% of microbial flora has been successfully isolated from marine environment. Coral reefs are the most diverse marine ecosystems, however, little is known about the microbial diversity in these ecosystems. It is expected that still quite a few parts of unexplored culturable invertebrate-associated microorganisms exists in the reef environments. The present study aimed at estimating the biodiversity of secondary metabolite-producing microbes associated with reefs invertebrates such as coral, soft coral and sponge collected from geographically different areas.

Abstract

Volcanic activities have infl uenced the Cisanggarung estuary in western Cirebon Regency, altering metal concentrations in the bottom sediment. Observation of metal content in the ocean there was carried out in August 2009. Sediment samples were collected at 16 stations along the Cisanggarung coastline. The aim of this work was to determine the spatial distribution of Cd, Cu, Pb and Zn in the sediment of the Cisanggarung estuary. Sediment was destructed using 3 acids: nitric acid, chloride acid and peroxide acid, which was then analyzed by Flame Atomic Absorption Spectrophotometry based on the US EPA 3050b method. The highest concentrations of Cd, Cu, Pb and 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 dry weight, respectively. The metals in the sediment had accumulated near the shoreline, up to fi ve kilometers away from the river mouth, indicating that terrestrial area and sediment fractions infl uenced their distribution.

Abstract

Effect of two sampling techniques (i.e. corer and sipper samplers) of sediment pore water on measured concentrations of phosphate, nitrate and ammonia was examined. The concentrations of nitrate and ammonia in relation to sediment depth (vertical variations) collected by corer and sipper sampler do not show significant differences, while for phosphate concentrations significant differences occurred. The advantages   and disadvantages of both techniques are discussed.

Abstract

A survey on heavy metal content in seawater and sediment was conducted in Jakarta Bay in May and October 2004. There is indication of significant presence of heavy metal in sediment. The contents of heavy metals in sediment at the western part of Jakarta Bay varied as follows: Pb = 10.67-35.19 ppm, Cd = 0.04-0.30 ppm, Cu = 7.41-74.70 ppm, Zn = 76.99-497.53 ppm and Ni = 4.58-18.75 ppm. At the central part of Jakarta Bay, they varied as Pb = 6.69-64.44 ppm, Cd = 0.01-0.442 ppm, Cu = 1.19-40.60 ppm, Zn = 53.87-275.68 ppm and Ni = 4.09-11.88 ppm and at the eastern of Jakarta Bay, Pb content varied between 3.64 and 43.97 ppm, Cd = <0.001-0.320 ppm, Cu = 0.82-36.47 ppm, Zn = 78.27-230.68 ppm and Ni = 4.58-11.02 ppm. The concentration of Pb in May and of Cu in Octobei 2004 were found higher near the coast and decreases towards the open sea, which is commonly found in front of estuary such Angke and Cengkareng Drain. The concentration of Cd in Jakarta Bay was constant at all stations and does not show any correlation with the distance of station and estuary. Heavy metals content in sediment was high in Jakarta Bay.

Abstract

The Kampar River estuary has a unique tidal bore, namely Bono. A tidal bore is a natural phenomenon caused by the tidal flow which meet the flow of the river. Tidal bore "Bono" has an impact on the transport of suspended particles which is pretty much along the Kampar River. The purpose of this study is to determine the estimated concentration of total suspended solid in the river as the result of the transport by Bono in Kampar River estuary by Landsat 8 OLI. The primary data are Landsat 8 OLI sensor – on Path 126 and Row 60, recording date was on 23 -04-2016, which was analyzed spatially – and TSS in situ. The secondary data are tide forecasting data and topographical map of Indonesia. Distribution of total suspended solid indicates sediment transport and its distribution by TSS values ranged between 10-150 mg.L-1 and TSS in situ value ranged between 42-241 mg.L-1. Tidal range ranged from 0.78 to 4.2 m and current velocity ranged from 0-0.9 m.s-1, which generate tidal bore extending from the mouth to the river body, resulting in suspended particle transport along the river. TSS concentration is higher in the river estuary.

Abstract

The study on the fluctuation of dissolved nutrient concentrations and acidity (pH) in the Cisadane Estuary was carried out in May 2004 October 2004 and July 2005. Inorganic phosphate, nitrate and silicate of the surface water were analyzed, using Spectrophotometer and pH was measured with a pH meter. Generally the nutrient concentrations in the estuary were higher compared to those in the coastal and offshore areas. The concentrations were gradually becoming lower and lower toward the open sea. Their fluctuation depended not only on the environmental condition but also on the water volurrie from the land and the mangrove forest in that area.

Abstract

Indonesia is considered to have a high diversity of sharks and rays due in part to its position in the equatorial line, between two continents and two oceans. According to recent studies and various publications, the number of chondrichthyan species known to date is 207 species of 44 families, comprised of 109 species of sharks, 96 species of batoids, and two species of ghost sharks (chimaera). The Dasyatidae (stingrays) is the most speciose family of chondrichthyans occurring in Indonesia, followed by the Carcharhinidae (whaler sharks). Most species of elasmobranchs commonly occur on the continental or insular shelves and rays are more commonly found than sharks. This type of habitat can be found mostly in the western part of Indonesia (the Java Sea, Karimata Strait, South China Sea, Malacca Strait, and Macassar Strait). Due to the separation by the Wallace Line, there are some differences in species diversity between western and eastern region. The shark and ray fauna of the eastern region is more similar to the Australian fauna, while the fauna in the western region is more similar to the Asian fauna. There are also some endemic species known to occur in Indonesian waters. The endemicity of some species can be restricted in a certain area or in a regional area such as the Indo-West Pacific.

Abstract

Maricullure in coastal zone, such as the bays, inlets, or lagoons in coral reef is becoming more important in the world fishery activities. In Indonesia, some culture experiments are being conducted, such as for oyster (Crassostrea tuculata BORN) in Banten Bay, and seaweed (Eucheuma spinosum) in Samaringa Islands (Central Sulawesi) and Talang islands (Riau Archipelago), while culture of cockle (Anadara granose LIN.) based on a simple method have been conducted by local fishermen from Ketapang (West Jawa) since several years ago. Some preliminary results of culture experiments are given.

Abstract

The efficacy of povidone iodine as a surface disinfectant was assessed in white shrimp (Litopenaeus vannamei) eggs and larvae. Eggs and nauplii were exposed to povidone iodine 20 ppm for 20 seconds. Culture-based method and Terminal Restriction Fragment Length Polymorphism (T-RFLP) were used to monitor the total number of bacteria and diversity of the bacterial community associated with shrimp eggs and larva at each developmental stage. Povidone iodine reduced the total culturable bacteria, especially Vibrio, on eggs and nauplii, as well as the total bacteria in the whole community as estimated by T-RFLP results. Povidone iodine also reduced the diversity of bacterial community and altered the evenness of phylotypes distribution suggesting that the use of povidone iodine as a surface disinfectant in shrimp aquaculture should be reconsidered.
