Abstract

This study aims to determine the distribution and relationship between the concentration of cadmium metal (Cd) and total organic matter (TOM) in sediments in the Tallo estuary, Makassar City. The study collected sediment samples from 12 points, distance of 500m between points sampling. Furthermore, 12 sediment samples were analyzed for Cd and TOM concentrations in the laboratory. The results of measurements of Cd metal in sediments showed concentrations ranging from 0.001 - 0.037 mg/kg. The concentration of Cd metal found was still in the low category. While the concentration of TOM in sediment ranges from 6.7 -30.3%, indicating a low concentration. The distribution of Cd and TOM showed that the farther from the estuary, the lower the concentration. Based on the results of the regression test, the relationship between Cd and TOM concentrations was 80.1%. This shows that the accumulation of Cd metal in Tallo River sediments is strongly influenced by the concentration of organic matter.

Abstract

Seaweed cultivation is an alternative community livelihood that potentially helping to reduce pressure on coral reefs in the area of Raja Ampat Archipelago. This study was aimed to conduct an oceanographic analysis of the waters of Meosbekwan Island (Raja Ampat Regency) for the suitability of seaweed cultivation. Oceanographic data collection was carried out at three points (M1, M2, and M3) on the western side of Meosbekwan Island. Analysis of suitability for aquaculture was initiated with an analysis of key parameters, i.e., depth, protection and shipping traffic. The suitability analysis was followed by an analysis of the oceanographic parameters of the waters by weighting them using a ranking system. Furthermore, the final stage of suitability analysis was to evaluate the feasibility level of seaweed cultivation. The results showed that the depth of the waters on the western side of Meosbekwan Island ranged from 1.3 m – 5.8 m with an average depth of 1.5 m in the south (M1), 2.2 m in the middle (M2), and 3.9 m to the north (M3). Wave height during the study ranged from 0.1 – 0.3 m with an average value of 0.25 m at all points. The velocity of the water currents ranged from 0.08 – 0.25 m/s. The salinity of the waters was relatively homogeneous (30 - 31 o/oo). Water temperature also has small and relatively homogeneous variations with a range of 30 - 31˚C. The brightness of the waters ranged from 2.5 – 3.5 m. The bottom of the waters on the west side of Meosbekwan Island generally consists of coarse sand, rubble, and seagrass vegetation Enhalus acoroides and Cymodocea sp. In general, the oceanographic conditions of the waters are suitable for the life and growth of seaweed. The results of the location suitability evaluation indicated that the waters on the western side of Meosbekwan Island were technically feasible to serve as a location for seaweed cultivation.

Abstract

Coastal areas are important for economic activities, but are also vulnerable to environmental changes caused by human activities. The use of remote sensing technology can assist in efficient and accurate monitoring of coastline changes related to the spatial-temporal dynamics of coastlines in local areas, which is needed in the development of effective coastal management strategies. By applying the Modified Normalized Difference Water Index (MNDWI) method for coastline extraction, the research results show that the addition of coastal areas (accretion) as a dominant process in coastal stability in almost all coastal areas of Gorontalo City during the period 2000-2022, has experienced the significantly accelerated trend during the 2015-2022 period with an increase in the accretion rate of 60.15%. The rate of accretion in this period has caused an increase in the land area of coastal areas by 425.44% compared to the accretion that occurred during the 2000-2015 period. The findings of this research can be used as a basis for further research regarding the impact of human activities on coastal ecosystems and the effectiveness of Gorontalo City's coastal management strategies.

Abstract

Degradation of coral reefs due to changes in environmental conditions causes corals to experience a decline in the number of organisms. Sponges, one of the components that make up the coral reef ecosystem, are known for their adaptability. Thus, the role of spongivore as distribution controllers is essential to assess. This research aims to determine the relationship between hard coral cover and sponge cover, the relationship between environmental parameters and sponge cover, and the preferences of predatory sponge fish. This research was conducted in July 2018 on Hoga Island, Wakatobi, by taking two stations with different conditions between clear and turbit water. At each station, benthic cover data was collected using the LIT (Line Intercept Transect) method, and environmental parameter data was collected using CTD (Conductivity Temperature Depth) and sediment traps. Predatory fish abundance data was collected using the belt transect and UVC (underwater visual census) methods, and the preferences of predatory fish were observed with visual observations for 5 minutes. The research results found that hard coral cover and sponge cover had an inverse relationship. Environmental parameters that significantly affected sponge cover were turbidity and sedimentation rate and high preference values for spongivore fishes.

Abstract

The presence of nutrients such as nitrate and phosphate can have a positive impact on phytoplankton growth. However, if the nutrient concentration is very high in the waters, it can cause an explosion in the phytoplankton population or Harmful Algae Blooms (HABs) in the waters. Phytoplankton explosions in waters have a negative impact on the surrounding ecosystem, marine biota, and humans. This research aimed to analyze the spatial distribution and structure of phytoplankton communities that can potentially cause HABs in the waters of Laikang Bay, South Sulawesi. This research was conducted in June 2021. The research found 20 species of phytoplankton HABs from 2 classes, namely Bacillariophyceae (8 types) and Dinophyceae (12 species). The Bacillariophyceae class has a higher percentage, 93%, and Dinophyceae at 7%. The abundance status of phytoplankton HABs is classified as not blooming, with the highest abundance found at Station 4 (control), namely 210 ± 80 cells/L. The HABs phytoplankton diversity index (H') is moderate with a value of 1.576 – 2.332, the uniformity index (E) of Station 1 (west) and Station 4 (control) is moderate with a value of 0.568 and 0.582 while Station 2 (north) and Station 3 (south) is classified as high, namely 0.807 and 0.823, the dominance index (D) is classified as low with a value of 0.135 – 0.357. Spatially, phytoplankton HABs based on the station can be divided into five groups. The results of the PCA analysis show that substations 1.A, 1.B, 1.C, 2.A, 2.B, and 2. C are characterized by high temperature and salinity parameters. Substations 3.A, 3.B, and 3.C are characterized by high nitrate and phosphate parameters. Meanwhile, substations 4.A, 4.B, and 4.C are characterized by high parameters of brightness, current speed, and pH and are associated with a high abundance of phytoplankton HABs.

Abstract

Labakkang Beach, Pangkajene Islands Regency has the characteristics of gently sloping coastal waters covered with various mangrove and seagrass communities. In general, seagrass is more commonly found in intertidal than subtidal areas, this is due to the depth reason. However, based on first observations, seagrass in Labakkang coastal waters thrives in subtidal areas and is less fertile in intertidal areas. The purpose of this study was to decide the differences in species, cover, and density of seagrass in intertidal and subtidal areas in the waters of Labakkang Beach, Pangkajene Islands Regency. This research was conducted in July 2021 with the method used, namely purposive sampling. Measurements of environmental parameters at the sampling location were carried out directly (in situ) including temperature, salinity, tides, depth, and current velocity, while turbidity, Total Organic Matter (TOM) analysis, and grain size of sediment were carried out tegakanirectly (ex-situ). The results of the average measurements of temperature, salinity, current velocity, depth, turbidity and TOM respectively show the range of 300C - 310C; 33.3‰ – 35.0‰; 0.07 m/s - 0.18 m/s (at high tide); 0.31 m - 1.32 m; 11.06 NTU - 29.04 NTU and 2.49 % - 5.39 %. The results of sediment analysis using Software Gradistat are 2 types of sediment, namely medium sand & fine sand and 2 types of sediment texture, namely Slightly Gravelly Sand and Slightly Gravelly Muddy Sand. The average percentage of seagrass cover at the intertidal station was 23.33 % while at the subtidal station it was 61.11% and only 2 species of seagrass were found, namely Enhalus acoroides and Halophila ovalis. The average density of seagrass at the intertidal station is 48.88 ind/m2 while at the subtidal station it is 86 ind/m2. The results of the Independent T-test analysis showed that there were significant differences in the cover and density of seagrass in the intertidal zone and subtidal zone in the coastal waters of Labakkang.

Abstract

Marana river estuary and its surrounding coastal area have been converted into extensive fishpond. This muddy environment with abundant fish in shallow waters, mangroves and Nypa palm attracts various species of birds to forage for food. This area also visited by migratory birds. However, avifauna in this area still poorly studied. Based on this, research on abundance, diversity of bird species and its conservation status was conducted. The aim of this study was to determine the abundance, ecological index and conservation status/protection status of bird species in coastal and estuary of Marana River, Maros Regency. Totally, six stations were set up in three different habitat types. Two stations were placed in the mangrove area around the mouth of the river, two stations in the pond area next to the river and two stations in the middle of the river that entered further inland. Data was collected using the point count method, with 3 replicates of different observation points set up randomly at each station. Each point has a circular observation area with a radius of 50m. The distance between observation points is 300m with a bird watching time of 20 minutes at each observation point. Bird species outside the observation area were also recorded but not counted. From the observations, a total of 22 bird species from 14 families were recorded from all stations. Most of the bird species dominated by waterbirds and open country specialized birds i.e: Whiskered Tern (Dara-laut Kumis), Glossy Swiftlet (Walet Sapi) and Little Egret (Kuntul Kecil). From ecological index analysis, bird community in all stations is categorized as stable, with moderate diversity, low dominance and high eveness index except for station 2 which is mostly dominated by Whiskered Tern. All bird species conservation status is categorized as Least Concern (LC) by IUCN. Little Egret (Kuntul Kecil), Cattle Egret (Kuntul Kerbau) and Great Egret (Kuntul Besar) are included in appendix III CITES. Furthermore, four shorebird species: Far Eastern Curlew (Gajahan Timur), Eurasian Whimbrel (Gajahan Pengala), Whiskered Tern (Dara-laut Kumis) and White-winged Tern (Dara-laut Sayap Putih) are protected by the Indonesian Government. It is concluded that bird communities in study sites are stable and Marana estuary can still support bird life, especially for migratory and protected bird species.

Abstract

Diatoms are a unique and specific group of microscopic algae, the body is composed of two valves, namely epitheca and hypotheca to form frustules, with cell walls made of silica (SiO3). Benthic diatom populations are highly variable and are common in waters. Bungkutoko Island is an island located at the eastern end of Kendari Bay. The rapid development and reclamation activities in the Bungkutoko coastal area, especially the construction of the port will affect the structure and topography of the environment. This study aims to determine the population of benthic diatoms in Bungkutoko waters in relation to the construction of a container port. The research was conducted at six observation stations using the purposive sampling method in August-September 2023. The results of this study found 13 genera of benthic diatoms, with abundance values ​​ranging from 342-492 ind/cm2. The diversity index value ranged from 1.82-2.00, the uniformity index value ranged from 0.82-0.91 and the dominance index value range from 0.15-0.20. Principal component analysis showed a correlation between the abundance of benthic diatoms and water quality parameters in the Bungkutoko waters.

Abstract

Anthropogenic activities that are often carried out by humans can affect the survival of mangrove, seagrass and coral reef ecosystems in an area. This research aims to determine the species, distribution and condition of the ecosystem on Karamassang Polewali Mandar Island. This research was carried out from April to December 2020 on Karamassang Island in Binuang District, Polewali Mandar Regency, West Sulawesi. Mangrove sampling uses a plot measuring 10 m x 10 m with four observation stations with three repetitions of each station with a repetition distance of 5 m. Data collection on seagrass beds with estimates of seagrass cover was carried out by stretching a line transect along 100 m and placing 0.5 x 0.5 m2 quadrants with grids at 20 meters intervals. This transect was carried out at a location that has a seagrass ecosystem and coral reef ecosystem data was collected using the RRA (Rapid Reef Assessment) method. The results of research on the types of mangroves obtained on Karamassang Island were Rhizophora mucronata, Avicennia alba, and Sonneratia alba. In general, the density of mangroves is very dense. In general, seagrass cover is in the good category. In general, the condition of live coral cover is in poor condition.
