Published: January 2018

The grouper hatchery technology has been successfully developed and grouper seed can be produced massively and sustainly. Egg is one of key successes in the hatchery processes. Eggs taken from hatchery egg producer were often far away from a final hatchery location. This study tried to find out the effectiveness of eggs transportation duration and densities for eggs’ hatchability of tiger grouper (Epinephelus fuscoguttatus). The first treatment: eggs at a density of 400 000 eggs/8 l sea water, transported with different duration time i.e., 6, 12, 18, and 24 hours. The second treatment: transportation eggs with duration 24-hour at different density i.e., 100,000; 200,000;300,00; and 400,000 eggs/8 l sea waters. Eggs were packaged in a plastic bag with 8 liters of water media, the plastic size 100 cm x 55 cm, ratio water with oxygen was 1: 3, the plastic bag inserted to sterofoam with size 75 cm x 40 cm x 30 cm, to reduce the temperature in sterofoam was added ice the size of 500 grams , wrapped in newspaper, styrofoam covered by selotipe. The results showed that eggs with transportation time of 6 and 12 hours were better and significantly different (P <0.05) than transportation time of 18 and 24 hours. Furthermore, density of 100,000 and 200,000 eggs/8 l sea waters were better and significantly different (P <0.05) than that density of 300,000 and 400,000 eggs/8 l sea waters.

Authors: Khozanah Khozanah 
Published: January 2018

Study on the distribution and sources of organochlorine pesticide concentrations in water samples and sediments from the Jakarta Bay was conducted in April 2011 (transition season I) and June 2011 (dry season). The purpose of this study was to determine the distribution of pesticide concentrations in water and sediments and to identify possible sources of organochlorine pesticides. The concentrations of organochlorine pesticides was measured by the GC/ECD (electron capture detection) HP 5890 series II. Concentrations found in the water column during transition I season ranged from 11.596 to 74.338 ng/l (average=41.998 ng/l) and in dry season varied from 4.554 to 19.119 ng/l (average=7.741 ng/l). In sediment samples, concentrations found in transition I season varied from 0.936 to 2.816 ng/g (average=1.782 ug/g), and in dry season about 0.7691 to 7.138 ug/g, (average=2.722 ug/g). In the water column, the average concentration in transition I was higher than that found in dry season, whereas levels in sediment during transition season I was lower. The average levels of pesticides in the water column was higher than those found in sediments. These results suggested that the seasons played a role in the distribution of organochlorine pesticides in the water column and sediments. Source of organochlorine pesticides were suggested from agricultural activities in the mainland Cisadane. Keywords: organochlorine pesticides, DDT, BHC, Jakarta Bay waters.

Published: January 2018

Research on the seasonal geostrophic surface current during 2002-2011 in Arafura-Timor waters was conducted using satellite altimetry data. Those data were absolute dynamic topography and absolute geostrophic velocity data taken from Archiving Validation and Interpretation of Satellite Oceanographic data (AVISO). The dynamics of geostrophic surface current varied in every monsoon due to the difference in absolute dynamic topography. During northwest (NW) season, the absolut dynamic topography in Arafura Sea was higher than in Timor Sea by an average difference of 0.1–0.2 m and the geostrophic surface current moved from Arafura Sea toward Timor Sea. During southeast (SE) season, the absolute dynamic topography in Arafura Sea lower than Timor Sea with an average difference of 0.03-0.04 m. In this season, upwelling occurs in Banda Sea and sea surface water in this region becomes lower and the current moved from Arafura Sea to Banda Sea. The absolut dynamic topography difference between Arafura Sea and Timor Sea in NW and SE monsoons was 0.05–0.06 m and so the geostrophic surface current moved from Arafura Sea toward Timor Sea. In Timor Sea, the current moved southwest towards the Indian Ocean. In NW and SE Monsoons the the velocity of surface geostrophic current in Timor Sea (0,3 m/sec) was higher compare in Arafura Sea (0.2 m/sec) due to the configuration of island surround the Timor Sea and its topography.
