Abstract
Water salinity is one of the environmental factors that affect the hatching rate of the fish. The aims of this study were to find out the influence of salinity to embryogenesis and hatching rate of giant gourami at the different salinities. This study used four treatments and three replications. The treatments were A 0 ppt, B 1-2 ppt, C 3-4 ppt, and D 5-6 ppt. The salinity was made by adding salt water to the fresh water in aquarium. The number of eggs in each treatment was 32 grains respectively. The parameters observed were the embryogenesis, fertility, hatching rate, hatching time, and water quality. The results showed that salinity influenced the embryogenesis duration of eggs during blastula and gastrula stages, but did not influence to the hatching rate and hatching time of eggs.

Abstract
Corals are cultured as a multiplication effort to conserve the recovery of coral reef ecosystems in natural habitat or sold as ornamental biota for saltwater aquariums. Coral cultured requires a substrate for the enlargement of transplanted coral tillers, where the substrate must be in accordance with the needs and conditions of the aquatic environment. This assembled concrete reefs as a stand is designed to be resistant to the conditions of the monsoon season sea waters. Artificial reefs made of concrete designed with concrete beam where each beam has a dimension of 1 m in length, 10 cm in width and 10 cm in height are arranged in specific form so that it is easy to assemble to place on the seabed. The test results shown that this structure for 12 months on the seabed is still intact, the position of the structure has not shifted, the transplanted coral has remained attached, natural epiphytes already attached after 1 month and are attached until next 11 months.

Abstract
A study aims to understand the effects of photoperiod manipulation on the biological aspects of Pangasius hypopthalmus was conducted in June 2019. There were 3 treatments applied, namely control (natural light); 24 hours dark (24D) and 18 hours dark (18D). The treated fishes were reared in tarp ponds (75 × 50 × 60 cm) and kept under dark blue plastic tents 24 hours (24D) and 18 hours (18D) continuously. There were 20 fishes/tank and they were fed on commercial fish feed 2 times/day, 5% of total fish body weight. Data on fish growth were collected 3 times, just before the treatment, in the 2nd and 4th weeks after the photoperiod treatment. Data on the fish behavior were collected during the 2nd week, by monitoring fish behavior hourly for 72 hours continuously. Data on blood condition were collected from the fish 2 times, before the treatment and in the 4th week. Results indicates that the 24D provided the best results in fish growth, by the 4th week, the fish TL value was 123.5 mm and BW was 5.6 gr. The blood condition of fish in all treatments were normal and there was not significantly difference, with hematocrit value was 30%, 1.5% of leucocrite levels, 70% of lymphocyte and 30% of other leucocyte types. The shortened photoperiod duration positively affects the growth of P. hypopthalmus growth, but it does not affect the biological aspect of the fish in general.

Abstract
Bengkalis waters is relatively busy traffic area due to regional and international marine transportation which is very vulnerable to oil pollution. Cleaning of oil spill could be attempted by the use microorganisms (bioremediation). Bioremediation is an effective, economical and environmentally friendly treatment method in which microbes are used to degrade hydrocarbons. The objectives of this research were to isolate oil-degrading bacteria from seawaters in the North coast and in the South area of Bengkalis Island, to examine the bacterial isolates in degrading crude oil and to identify the isolates by phenotype (morphological observation, biochemical tests) and genotype characters (16S rDNA sequence). Bacteria was isolated on SMSS basal medium, oil content was measured by Gravimetry method, DNA sequence was analized by using polymerase chain reaction (PCR) followed by sequencing using genetic analyzer machine. Sixteen bacterial isolates from the seawaters had different morphology, physical and biochemical characters. Six isolates from the North coastal waters (BM 1a, BM 1c, BM 1d, BM 7a, BM 14a and BM 14b) and three isolates from Sungai Pakning waters (S1P26B, S2P35b and S3P35a) showed high ability in degrading crude oil at concentrations 1%, 2% and 3%). DNA sequence analysis indicated isolate BM 1a had similarity to Bacillus circulan W239 (99%), isolate BM 1c was similar to B. thungiriensis LDC507 (92%), isolate BM 1d was similar to B. flexus CORSS01 (96%), isolates BM 7a and S1P26B were similar to B. cereus MBGIPS 18 (94% and 95%, respectively), isolate BM 14a was similar to B. flexus MDLD1 (, isolate BM 14b was similar to B. thuringiensis LDC 507 (98%), isolate S2P3 5b was similar to B. cereus KJW1 (98%) and isolate S3P3 5a was similar to B. cereus MCCC1a06185 (99%). In conclusion, bacteria of genus Bacillus dominated the crude-oil degrading bacteria from Bengkalis Island waters.

Abstract
Development of infrastucture will increase sporadic land use and tend to cause land degradation. This paper is intended to investigate the effects of land use and land cover (LULC) processes on Weh-Sabang Island, Indonesia. The duration of LULC changes is analyzed using Google Earth image and ArcGIS from 2008 to 2018. Through observations of satellite imagery detected protected area and green space area has been greatly reduced in area and transformed into built-in land which functions as a tourist area and urban built environment. The increase in land density since 2008 is due to the construction of tourist attractions in hilly areas to coastal areas around Weh-Sabang Island, and can cause changes in the morphology and typology of the city of Sabang. Through the method of calculating the Land Diversity Index, changes can be made in the number of areas that have changed in the period of the year being monitored. This paper focuses the development of an ArcGIS Weh Island map with the analytical hierarchy process (AHP). It is expected that efforts will be made to control land use changes in areas that have directly experienced land degradation, and analysis of water resources carrying capacity in Weh Island.

Abstract
Eddies have an important role in momentum transport, water mass, heat, and marine biogeochemical cycles. So far the information regarding eddies in the Andaman Sea is still little known. By using National Centers for Environmental Prediction (NCEP) / National Center for Atmospheric Research (NCAR) wind data, Sea Surface Height (SSH), and geostrophic currents obtained from altimeter data, this paper aimed to detect eddies during April (intermonsoon). Eddies were formed by current turbulence, gradient pressure variations, and the influence of sea surface wind. Observations showed that the SSH variations was supported by the west wind from the Andaman Sea. Spatial SSH differences caused the dynamics of geostrophic currents and eddies. During April 2008, we found six eddies scattered around the Andaman Sea, where there were four eddies cyclones and two eddies anticyclones.
