Abstract

Makassar Strait has been identified as an area of interesting studies for marine science and operational fisheries. It provides the unique ocean structures such as topographic feature, the main path of the Indonesia Throughflow (ITF) and dynamics of thermal fronts.  The aims of this study were to map the dynamic spatial and temporal of the thermal fronts, and to describe their implications to the pelagic fisheries. We used satellite data of sea surface temperature (SST) for the period of January-December 2018 with spatial and temporal resolutions of 4 km and monthly, respectively. For fishery data, we used sampling data of skipjack tuna fishing ground distributions in October and December 2018.  Thermal fronts throughout the year were estimated using a Single Image Edge Detection (SIED) algorithm and the available fishing ground data were overlain on the SST front map.  The results showed that the spatial distributions of thermal fronts along Makassar Strait tended to be different every month. However, the thermal fronts were consistently detected near the upwelling area from June to September. Skipjack tuna fishing grounds associated with fish aggregating devices (FADs) developed in the northern area of upwelling in October. Two month later, the FADs and free swimming skipjack fishing grounds again well formed around the same location. It implies that the formation of the thermal fronts after upwelling contributes the positive effect on development of pelagic fishery especially skipjack in Makassar Strait.

Abstract

Aquaculture activities produce organic wastes that are discharged into coastal waters and may impact the water quality. This research aimed to study the status of organic pollution and its spatial distribution on the west coast of South Sulawesi, Indonesia. Water was sampeld from two locations (Punaga Village, Takalar Regency (an open water system), and Bojo Village, Barru District (in a bay, a semi-closed water system)). Water quality was assessed by using the STORET index. Whilst to assess the spatial distribution of organic waste, an interpolation technique was used. Results showed that the water quality was categorized as highly polluted by organic pollution. The distribution of the organic pollutant, however, showed a different spatial pattern between the two locations. The difference was may be due to the different origin of the pollutant and geomorphology of the sampling locations.

Abstract

Jellyfish can be found in most coastal waters and their occurrence can be frequent during the day. This study aimed to detect the occurrence of jellyfish based on the oceanographic condition in the coastal waters of Makassar. Observations were conducted in July-September 2018 at three stations namely Port of Soekarno Hatta (Station 1), Port of Paotere (Station 2), and Port of Untia (Station 3). Jellyfish sampling was conducted in the morning, noon and afternoon, from three stations as aforementioned. Jellyfish samples were taken and identified at the Laboratory of Marine Biology, Faculty of Marine Science and Fisheries, Universitas Hasanuddin. Oceanographic conditions, i.e. temperature, salinity, transparency, and current velocity, were measured. All data were analyzed descriptively. It showed that the oceanographical conditions were in the suitable range for supporting jellyfish growth. Three genera of jellyfish were found, namely Aurelia, Porpita, and Aequorea. Aurelia was abundant in Station 1 and 2, whereas Porpita in Station 3. It also showed that during the afternoon, the jellyfish occurred more frequently.

Abstract

The Spermonde Islands are part of the mega diversity area in the world's coral triangle area, crossed by the Wallace line. The Spermonde Archipelago consists of 120 islands spread over four zones: the inner zone, middle inner zone, middle outer zone, and outer zone. Samalona Island is located in an inner zone with a high level of eutrophication, and Langkai Island is located in an outer zone with a high brightness level. This study aims to determine whether there are differences in zooxanthellae density in various life forms and coral reef zones in the inner and outer zones of the Spermonde Islands. Coral sampling was done at coral reef ecosystems on Samalona Island and Langkai Island using SCUBA tools, cutting tools, and plastic samples. The zooxanthellae were separated from their hosts using a modified airbrush sprayer with an air pressure of 3000 psi. The zooxanthellae density was calculated using the formula of Eaton et al. Water qualities were measured in-situ using the water quality checker. The data were analyzed using factorial analysis with two factors. This study indicates that the zooxanthellae density in the folios life form is higher than in the encrusting and branching life forms. This study indicates that: (1) the zooxanthellae density in the same life form is not significantly different between the inner zone and outer zone; (2) the comparison of the zooxanthellae density in the same coral reef zone was not significantly different between the inner and outer zones; (3) the comparison of zooxanthellae density in the same coral reef zone was significantly different between life forms in the inner zone (Samalona Island); (4) the comparison of the zooxanthellae density in the same coral reef zone was significantly different between the life forms in the outer zone (Langkai Island).

Abstract

. The aim of this study were to analyze the success of coral reef restoration techniques due to the coral bleaching phenomenon by using several forms of dead coral substrates as a transplantation technique based on the growth and survival of several types of transplanted fragments and to analyze the linkages between coral transplanted growth and environemtal factors. Growth and survival of the transplanted corals on a natural substrate with measured environmental parameters. There are three observation stations for each form of dead coral substrate (natural substrate) which will be used as an attachment medium. The area selection is based on the extent of the bleaching event at a depth of 3-5m. The technique for restoring coral reefs that will be carried out was the transplantation technique which was carried out by three methods, namely by 1) utilizing a natural substrate (dead coral as a coral attachment medium) with a massive form, 2) utilizing a natural substrate with a branching form, and 3) utilizing a natural substrate with a tabulate form. Corals used as transplant fragments were Acropora nobilis, Acropora formosa, and Porites cylindrica. In this study, several environmental parameters were measured, i.e., temperature, salinity, pH, and current velocity. Based on the growth and survival rate values of the Acropora nobilis, A. formosa, and Porites cylindrica species, the use of dead coral substrates (massive, tabulate, and branching) as natural substrates is equally effective in rehabilitating coral reefs due to the bleaching phenomenon. The mean value of coral growth on massive media ranged from 0.04 - 0.35 cm, Tabulate media ranged from 0.04 - 0.32 cm, branching media ranged from 0.04 - 0.20 cm, and on natural media as control media ranged from 0.08 - 0.35 cm. The survival rate of transplanted corals for 4 months of observation showed a relatively high value with general survival rates ranging from 86.67% - 93.33%. Based on the type of media used, it has the same survival value in massive media, i.e., 93.33%, while in tabulate media the survival value is around 86.67% -93.33% and Acropora media is around 90% -93.33%.

Abstract

Dunaliella salina is a green microalgae that has the ability to produce β-carotene used in various fields, such as food supplements, natural colorant, antioxidants, anti-cancer, and anti-aging. D. salina is capable of producing large amounts of carotenoids under stressful conditions, including light and nutrient. Light is the main factor that stimulate the production of carotenoid pigments and media composition plays an important role for growth, biomass, and β-carotene production. The accumulation of β-carotene in microalgae is closely related to the type and quality of light and the composition of the culture media. This study aimed to determine the production of β-carotene in microalgae D. salina using LEDs and different culture media to select the best culture conditions for producing high value compounds. The results showed that D. salina cultured using red LED light and technical Walne media was able to produce β-carotene with the highest amount of 767,499 mg/100 g. In blue LED light and Walne Pro-analysis media, the β-carotene content was 380,522 mg/100 g, while the ZA+NPK media has the lowest value. In this study, Walne Pro-analysis media became the best culture medium for D. salina. Therefore, natural sources of β-carotene can be obtained from D. salina, so it could reduce the use of synthetic carotene in meeting global demand.

Abstract

The distribution of macroalgae in the waters is influenced by various environmental factors ranging from anthropogenic pressures such as the activities of local communities and tourists to the Physico-chemical effects of the waters. This study aims to examine the effect of environmental parameters on the distribution of macroalgae and to map the spatial distribution of macroalgae on Lae-lae Island and Gusung Lae-lae Caddi. Data collection for macroalgae was carried out using a 1 × 1 m transect method and environmental parameters were surveyed using in situ measurements and further analysis in the laboratory. The status and diversity of macroalgae were calculated using ecological indices, distribution of macroalgae using Mapping Techniques, and the interrelationships between parameters were tested using Principal Component Analysis (PCA). The results showed that the largest macroalgae cover was found in Gusung Lae-Lae Caddi by 55% with the average distribution of macroalgae cover respectively; Lae-laen Island East Station 9%, Lae-lae Island West Station 36%, Gusung Lae-lae Caddi East Station 21%, and Gusung Lae-lae Cadii West Station 55%. The high macroalgae cover in Gusung Lae-Lae Caddi is influenced by nutrients and the low level of turbidity. Based on the calculation of the ecological index, it was found that the ecological status was dominated by the late-successional group.

Abstract

This study aims to describe the relationship between the upwelling area and the ZPPI area of ​​skipjack tuna using the Generalized Additive Model (GAM) method and to map out the distribution pattern of skipjack in Barru waters, Makassar Strait. The research was conducted in November and December 2020, located in Barru waters, Makassar Strait. The research method used two methods by collecting primary data in the form of catches by following the purse seine fishing operation in Barru and secondary data in the form of satellite imagery data on sea surface temperature and chlorophyll-a. The data were analyzed using the GAM and upwelling area analysis. The upwelling area was obtained from the combination of the referred values of the two parameters. The results showed that sea surface temperature parameters had a significant effect on the catch of skipjack tuna with favored range of 28.5 - 29.7 oC.  Preferred chlorophyll-a ranged from 0.15 to 0.23 mg m-3. We found that the upwelling event in the Flores sea does not have a direct effect on the distribution pattern of skipjack tuna, there is probably a time lag required after upwelling in which in turn has an impact on the distribution of skipjack tuna in the southern Malassar Strait. Keywords: skipjack distribution, Makassar Strait, upwelling area, Flores Sea, potential fishing zone area
