Abstract :

Along with the rapid growth of the city of Makassar, space utilization in the industrial sector and other human activities provide economic benefits. However, it also poses a variety of problems such as pollution in the coastal waters which is assumingly very high, due to the two major rivers i.e., Jeneberang and Tallo, as well as canals and drainages that flow into the coastal waters of Makassar. This study aimed to: 1) determine the Physical-Chemical paramater, 2) macrozoobenthos community structure and 3) relationships between the Physical-Chemical parameter with macrozoobenthos. This research is expected to provide information regarding the condition of the waters and the structure and density of macrozoobenthos in Coastal Waters of Makassar. Measured parameters were temperature, clarity, current velocity, salinity, degree of acidity (pH), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Total Suspended Solid (TSS), sediment Organic Materials Total (BOT), and macrozoobenthos diversity. Results showed a strong correlation between the physical-chemical parameters with macrozoobenthos density, in two-way correlations (positive and negative). It is concluded that the water quality of Makassar city waters is polluted, however, this condition was tolerated by macrozoobenthos. There were 5 species of Gastropods found was many as 5 species of gastropod class, and 4 species of Bivalves. In addition, based on the analysis, there is a strong relationship between environmental parameters to macrozoobenthos densities.

Abstract :

Mangrove is one of the coastal ecosystems with important roles in the estuary. The mangrove ecosystem has the highest level of productivity compared to other coastal ecosystems. Mangrove is also a place for finding food, spawning and breeding for shrimp and fish as well as shellfish and crabs. Copper (Cu) is an essential metal required by organisms in the process of metabolism. But the increase of Cu in the environment can be harmful to the organism. The main source of Cu in marine waters derived from the use of antifouling paints on ships and the use of pesticides and fungicides. The purpose of this research is to analyze the content of Cu in sediments of mangrove ecosystems and mangrove roots and analyze the linkages of metal concentrations in sediment and roots with the physical-chemical parameters of the sediment. This research will provide new information on the assessment criteria for areas with sediment metal contaminated. The research methodology includes the preparation, determining the location, retrieval and sample preparation (roots and sediment), sediment character analysis, measurements of environmental parameters, and measurement of the concentration of metallic copper (Cu). In stations with high density, we found high metal concentrations in the sediment (cummulative percentage = 55.29mg/kg). Whereas low concentrations (20.13 mg/kg) were in low densities stations. The highest concentration of metal that we found in the roots were from low densities station with a value of 42.45 mg / kg, while roots with low metal concentrations (24,11%) were found in stations with high densities.

Abstract :

Waters for recreational purposes must be free from microbiological hazard for the safety and health of users. Particularly microbiological, i.e. pathogenic bacteria Salmonella sp. This study aimed to detect the presence of pathogenic bacteria Salmonella sp. in water baths of the city of Makassar. This study was conducted in August – September 2016. Salmonella sp was sampled during high and low tide in three water-baths in Makassar, i.e., Tanjung Bayang, Akkarena and Popsa. Further observation of the samples were performed at Marine Microbiology Laboratory of the Department of Marine Sciences, Hasanuddin University. Total organic matter analysis was conducted at the Laboratory of Chemical Oceanography, Marine Science Department, Hasanuddin University. Filter method (Membrane Filter Method) is a method that uses filter paper (membrane filter). Furthermore, the filter paper is placed in the cup containing BSA (Bismuth Sulfite Agar) medium. After that, it was incubated in 37∞C in less than 48 hours for bacterial growth. Furthermore, it was directly counted in the direct count saucer. Data were analysed by T-test. During high tide, the average number of bacteria Salmonella sp. found from the three water baths of Makassar, i.e. Popsa, Akkarena and Tanjung Bayang (respectively) were 658; 276; and 324 cfu and during low tide were 126; 1211; and 24 cfu.

Abstract :

Porites is one of many coral genera that is not vulnerable to increased temperature and when subjected to bleaching they tend to recover and with little or no increase in mortality. Thi study aims to 1) determine the effect of temperature on the abundance of zooxanthellae and 2) analyze the relationship between temperature with the abundance of zooxanthellae in Porites cylindrica in a laboratory scale. This study was conducted in April-July 2016 at the Wet Laboratory or Hatchery Marine Station, Faculty of Marine Sciences and Fisheries, Hasanuddin University, in Barranglompo Island. Abundance is the number of cells within the host tissues, measured by units of cells / cm2. Zooxanthellae cells are separated from their tissues by spraying them with high-pressure air (air brush). Furthermore, the zooxanthellae cells are calculated by using a hemocytometer. After a four-week experiment, it showed that the highest abundance of zooxanthellae (6518042.20 cells / cm2) from Porites cylindrica were obtained at 28∞C temperature treatment, while the lower abundance (2261767.802 cells / cm2) was obtained at 34∞C temperature treatment. Based on these results it can be concluded that the temperature 28 ñ 29.8∞C is the optimum temperature for the growth of Porites cylindrica.

Abstract :

This study aims to find out: 1) the community structure of macrozoobenthos in mangroves, 2) total organic matter content (BOT) in the sediment at different densities of mangroves, 3) the density of macrozoobenthos with total organic matter content (BOT) in the sediment. The research was conducted from May to September 2016, in Ampalas sub-disctrict, Mamuju district, West Sulawesi region. This study covered the density of macrozoobenthos, species identification, diversity, similarity and dominance index, uniformity indices, the density of the mangrove species, and the total organic matter content (TOM). Supporting parameters such as the redox potential (Eh), pH, salinity, temperature , dissolved oxygen (DO) and sediment texture, were also measured. Results showed that Rhizophoraceae dominated the area. The higher the density of the mangrove, the higher the total organic matter content (TOM). This showed that high TOM influenced the density of macrozoobenthos. SPSS data analysis showed significant differences of macrozoobenthos densities among stations.

Abstract :

This study aims to determine the number, type and weight of accumulated marine debris based on their size and on the condition of the highest and lowest tide in three research locations and how they may impact the ecosystem (qualitatively). The locations were, Akkarena Beach (a tourist destination), Tanjung Bayang and the island of Lae-lae (Bob Beach), in the City of Makassar. It is assumed that these locations are have the potential to accumulate trash due to the tourist activities that may threaten the marine microbial life. This study was conducted in September 2016. Plots along 100m x 25m facing 50m inward and 50m outward. Subsequently, litters found on the plot we
re collected. We conducted 3 replicates in each location with the “parallel line” rule. We also measured the physical oceanography paramater, i.e., direction and speed of currents and waves). Results showed that marine litter in the vicinity of Bob Beach (Lae-lae Island) was the largest in terms of number and mass, followed by Pantai Tanjung Bayang and the lowest was in Akkarena Beach. Litter size of 2.5 cm –

Abstract :

Salmonella is a bacteria that causes typhoid diseases in humans. Typhoid disease often occurs in small islands, including Barranglompo. Presence of Salmonella in seagrass ecosystems and coral reefs may have an impact on water quality and marine life that led to humans. This study aims to determine the number of Salmonella from the inner beach, middle (seagrass) and outer (coral). To determine the number of Salmonella in the water column and sediment. To determine the number of Salmonella in areas with and without seagrass. Sampling was done in Barranglompo island, i.e. the inner beach area (with and without seagrass), middle beach area (seagrass) and outer (coral) with 3 replicates each. Water were sampled by using 150 mL bottle and the used 100mL of the water sampel for analysis. Sediment sampel was taken by using a cast, and used ± 100 gr for analysis. Samples were diluted 10-3 and each dilution was inoculated using castings in the Salmonella Shigella Agar (SSA) medium, incubated at 370C for 7 days. Standard Plate Count method was used to calculate the number of colonies. Results showed that the number of Salmonella in the middle part of the seagrass bed was relatively high. The number of Salmonella were higher in the sediment than in the water, both from locations with and without seagrass. Number of Salmonella in seagrass area is relatively high compared with areas without seagrass.

Abstract :

Acropora is one of the coral genera that has high growth rate, however, they are the most vulnerable to environmental threats such as temperature. Coral species used in this study was Acropora hyacinthus. This study aimed to determine the effect of temperature to the density of zooxanthellae in Acropora hyacinthus (a laboratory scale). This study was conducted in April-July 2016 at the Marine Station Hatchery, in Barrang Lompo Island, operated by the Faculty of Marine Sciences and Fisheries, Hasanuddin University. Density is the number of cells within the host tissue and measured by unit of cells / cm2. Zooxanthellae cells are separated from their tissues by spraying them with high-pressure air (air brush). Furthermore, the zooxanthellae cells are calculated by using a hemocytometer. After a four-week experiment, it showed that the density of zooxanthellae from Acropora hyacinthus was the highest (113 361 cells / cm3) at 300C, while lowest density (75 306 cells / cm3) was obtained at 320C treatment. At 280C and 340C treatment, Acropora hyacinthus were bleached and died as they could not cope with the temperature. Based on these results we can conclude that 300C is the optimum temperature for the growth of Acropora hyacinthus.
