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

Abstract

Seagrass distribution is influenced by many factors, including sediment characteristics. This study aims to determine the distribution of seagrass based on their sediment characteristics. Observations and sampling were carried out in the waters of the Puntondo Bay, Takalar Regency. This study observed the cover and density of seagrass species, water depth, water transparency, sediment’s total organic matter and size of sediment grains. There were five species of seagrass found in the area, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis and Syringodium isoetifolium with sediment types of medium sand and coarse sand. Results of the regression analysis showed that the relationship between sediment particle size and seagrass density with the  highest coeficient determination (R2=0,3346) was in seagrass Cymodocea rotundata, whereas the lowest was in  Syringodium isoetifolium. Keywords: Seagrass, Puntondo, aters, Sediment grain size, Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis, Syringodium isoetifolium.

Abstract

Marginal coral reefs are located in a limited aquatic environment, causing coral organisms to live under threat and only certain species of coral are able to survive. Porites lutea is one species of coral that is able to live in normal and marginal coral reef conditions. The purpose of this study is to determine the ecology of Porites lutea, the physiological ability of Porites lutea's Productivity (P) and Respiration (R), coral reef habitat conditions and environmental factors that affect the distribution of Porites luteal in normal and marginal locations. This study used the belt transect method, measurement of coral colony volume, physiological productivity (P) and respiration (R), transect picture for substrate cover and coral reef conditions and CTD to measure environmental indicators such as temperature, salinity, turbidity, chlorophyll and DO. The results shows that the density of Porites coral is higher at normal coral reef locations (Pak Kasim), the highest volume range is 25-100 cm3, with the largest size in the 451-475 cm3 class. P/R values ​​is higher at normal coral reef sites, especially in reef slope areas. Coral reef habitat cover is dominated by abiotic components with poor coral reef conditions in marginal and normal environments. Water temperature was significantly different (P=0.039) between two normal and marginal locations with a range of 27.08 - 27.51 oC, Salinity was significantly different (P=0.145) with a salinity 33.44ppt at normal locations and 32.88 ppt at marginal locations. The chlorophyll and oxygen number was not significantly different between the two locations, the range of chlorophyll 0.03 – 0.15 mg/L and oxygen 2.49 – 5.23 mg/L. The turbidity factor was significantly different between locations (P=4.86E-07) where the marginal location in Sample was more turbid than the normal location in Pak Kasim. This study shows that there are differences between normal and marginal waters in environmental conditions and physiological reactions of Porites lutea, but this coral is able to survive to show their resilience to environmental stresses.  Keywords: Coral physio-ecology, Porites lutea, P/R ratio, marginal coral reefs.

Abstract

Kabung Island is an island located in Bengkayang Regency, West Kalimantan, Indonesia. The characteristics of these waters are sandy, muddy and muddy sand. This type of water is compatible with the life of Gastropods and Bivalves. Both of them play an important role in an ecosystem because of their ability as a filter feeder that filters dissolved substances in the water, for a source of food for their survival. The abundance and diversity of molluscs are highly dependent on the conditions of the aquatic environment, such as substrate type, pH, turbidity, temperature, salinity and dissolved oxygen, availability of food, pollutants, predators and competitors. This study was aims to assess the diversity and abundance of molluscs on the Kabung island. The results on this research show that the highest diversity index is 1.94 which means that it is in moderate condition. The evenness index and dominance index values found to show a value of 0.88 which means high evenness so that a dominance value of 0.45 means that there are no molluscs that dominate on the Kabung island. Keywords: Abundance, Bivalves, Diversity, Gastropods, Mollusca.

Abstract

Green macroalgae Caulerpa racemosa from the waters of Lemukutan Island was isolated to obtain endophytic fungi. Endophytic fungi were explored to determine the antibacterial activity. Isolation of endophyte fungi was carried out by dilution method using PDA (Potato Dextrose Agar) seawater media. Endophyte fungi with different morphology were obtained 11 isolates, namely CRF01, CRF02, CRF03, CRF04, CRF05, CRF06, CRF07, CRF08, CRF09, CRF10 and CRF11. Antibacterial activity testing was carried out by agar diffusion method. Endophyte fungi isolate CRF09 showed the highest activity against both Escherichia coli and Staphylococcus aureus test bacteria with inhibition zone diameters of 15.96 mm and 16.47 mm respectively. Endophyte fungi isolates identified from the green macroalgae Caulerpa recemosa were of the genus Trichocladium sp., Aspergilus sp., Chaetomium sp., Coprinus sp., Hymenochaete sp., Rhizopus sp., Trenella sp. and Zygorhynchus sp. Keywords: antibacterial. endophyte fungi, Caulerpa racemosa, Lemukutan Island, activity

Abstract

Nudibranchia is one of the interesting and unique organisms because it has different shapes, sizes and colors attracting tourists when doing snorkeling and diving activities. However, because the distribution of marine biota is very dependent on habitat conditions and the availability of food types, it affects the density and diversity of Nudibranchia in the waters. The purpose of this study was to determine the density and diversity of Nudibranchia species. This research was conducted in March-April 2021 on Samalona Island, Barranglompo Island, and Badi Island in the Spermonde Islands, South Sulawesi. The method used is the Belt Tansect method with a length of 100 m with a sweep of 2.5 m to the left and right, at a depth of 4-7 m. Based on the results of the study, the number of Nudibranchia species found on Samalona Island was 4 families, 7 species, and 36 individuals; on Barranglompo Island as many as 4 families, 6 species, and 51 individuals; while on Badi Island there are 3 families, 6 species, and 30 individuals. Nudibranchia density on Samalona Island is 0.024 ind/m2, on Barranglompo Island is 0.034 ind/m2, while on Badi Island it is 0.020 ind/m2. The value of the Nudibranchia Diversity Index on Samalona Island is 1.14; on Barranglompo Island by 0.96; and on Badi Island it was 1.28 with a diversity community structure that was quite stable to stable on each island. Substrate cover conditions found on each island were dominated by Dead Coral Algae (DCA), on Samalona Island at 58.33%; Barranglompo Island by 54.90%; and Badi Island by 66.67%. Keywords: Nudibranchia, density, diversity, Samalona Barranglompo, Badi.
