Published: October 2017

Sediment oxygen consumption level is an indicator of mineralization procces intensity and indicator of microorganism activity in the substrate, and also a description of dissolved oxygen consumption or utilization in a water body. This study aimed to evaluate factors of sediment quality which influenced sediment oxygen consumption level. The study was conducted at the experimental pond installation of Research Institute for Coastal Aquaculture (RICA), in Punaga, Takalar Regency, South Sulawesi, using two units of 4000m2 intensive ponds with density of 50ind./m2. Rearing period was approxi-mately in 4months. Pond management was carried out in accordance with standard operating pro-cedures. Homogeneity between experimental units was approached by the uniformity of pond management including pond preparation, shrimp seed management, feed management,and water management. Sediment quality variables measured were redox potential, pH, total organic matter, sediment oxygen consumption, total bacteria, and production aspect. The results showed that the factors which have close relationship with the sediment oxygen consumption were redox potential, organic matter, and total bacteria. The model could be used to predict the sediment oxygen con-sumption on white shrimp pond with the following regression equation Y= 0.0000496 + 0.00025 organic matter + 0.00037 total bacteria - 0.00000948 potential redox with R2 = 0.847.<br /><br /><em><strong>Keywords</strong>: sediment oxygen consumption, sediment quality, pond, Litopenaeus vannamei</em>

The samples were collected in Jakarta Bay in March and May 2013. The organochlorine pesticides concentration were measured by gas chromatography HP 5890 series II. The results showed that the average concentration of organochlorine pesticides in the small size of green mussells was 12.842 ppb, in the medium size was 27.065 ppb, and in the big size was 108.646 ppb. These concentrations were still lower than safety threshold limit value for seafood stated by EPA (Environment Protection Agency) i.e., 1,500 ppb.

The results showed that the humpback grouper F1 implantation treatment by methyl testosterone and estradiol showed good growth with an average body weight at the end of the observed ranged from 680 ± 60.5 to 820 ± 76,5g with an average body length of 34 -36 cm. In individual control growth better because during the maintenance of the population is not implanted. Analyses of testosterone and estradiol in the blood plasma showed that 40% of individuals in the population were males. Microsatellite analysis showed that F1 fish had good genetic variation (0.778-1.000) so that it can be used as broodstock candidate. </em>

The oil spills incident in this area caused by shipwreck from traffic on Tanjung Priok port and ALKI 1, as well as accident of petroleum exploration and exploitation. At least, oil spills in Seribu Islands have been recorded since 2003, 2004, 2006, 2007 and 2008. This study aims to calculate the vulnerability index of Pramuka island and Belanda island in the Seribu Islands. This research was conducted by using a theoretical approach of vulnerability (V), which is a function of exposure (E), sensitivity (S) and adaptive capacity (AC). The parameters in exposure category are tidal type, tidal range, wave height, substrat type, and water depth. Parameters in sensitivity category are growth type of reef, slope, protected ecosystem, coverage percentage, coral density, protected species, and fish abundance. Parameters in adaptive capacity are oil spill conti</em><em>n</em><em>gency system, conservation institution, community response, and economic dependence.
