Abstract

Geloina expansa is a clam found in mangrove forests. The high level of public consumption and high economic value, is suspected as the cause of overfishing. It is not impossible that continuous harvesting will result in a decrease in the population of G. expansa. The habitat of G. expansa has experienced a lot of land conversion and this will result in a decrease in the natural carrying capacity of its habitat. The purpose of this study was to determine the distribution and density, distribution pattern and size distribution of the population of G. expansa based on the ecology of its habitat in West Malangke waters. The method was carried out randomly, the transect was placed in a 5x5 m2 sample plot with 3 replications and collected directly by hand. Sampling was carried out on each plot at the lowest ebb. Environmental parameters measured in the field included salinity, temperature and substrate while parameters measured in the laboratory were total organic matter (TOM). The density value of G. expansa in the intertidal zone was 9.90 ind/m2 while in the subtidal zone it was 0.78 ind/m2. The distribution pattern found in the intertidal and subtidal zones is clustered. The size distribution of G. expansa in the intertidal zone found that the dominant G. expansa was adult size, and the lowest was in the old size class while in the subtidal zone the dominant size was young and the lowest was in the old size class. Zone and type of substrate affect the existence of G. expansa. G. expansa was found more in the intertidal zone than in the subtidal zone and clay-type of substrates were a determining factor for the presence of full-blooded clams while clay and sand-type substrates were limiting factors for the presence of full-blooded clams.

Abstract

This study aims to determine the concentration of copper (Cu) and lead (Pb) inseaweed Codium fragile and is expected to add information about copper (Cu) and lead (Pb) which accumulates inseaweed C. fragile in Puntondo waters. , Takalar Regency. This research was conducted from January to August 2021, located in Puntondo waters, Takalar Regency. This research method collects data in the form of seaweed samples from the field and seaweed obtained from seaweed sales. Data analysis was carried out using the One Way Anova test with a further test of LSD (Least Significant Difference). The results of this study indicate that the metal content of copper (Cu) at each research station in seawater and C. fragile samples has passed the threshold, while the content of lead (Pb) at each station in seawater and C. fragile samples has not passed the threshold based on PP No. 22 of 2021 (<0.008 mg/L) for sea water and BPOM Regulation No. 23 of 2017 (<0.2 mg/kg) for consumption materials. The metal content of copper (Cu) in seawater at each research station was significantly different and the metal content of copper (Cu) in C. fragile at each research station was not significantly different. The metal content of lead (Pb) in C. fragile seaweed at each research station was significantly different and the metal content of lead (Pb) in seawater at each station was below the detection limit of the instrument (<0.01 ppm). The highest content of copper (Cu) in seawater was found at stations near from the ships activity, that is 0.3625 mg/L, followed by stations close to settlements at 0.235 mg/L. The highest content of copper (Cu) in C. fragile was found at stations close to settlements at 6.63 mg/kg followed by stations at PPI Beba at 6.1575 mg/kg and stations close to ships activity at 4,965. mg/kg.

Abstract

Characteristics and distribution of bottom sediment is one of the important parameters in determining the management plan and land use in coastal areas. The purpose of this study was to determine the condition of the distribution of bottom sediments and to compare the changes that occurred in the distribution of bottom sediment before and after the reclamation of the Center Point of Indonesia (CPI) in Makassar City. Sediment sampling was carried out using a grab sampler at four stations, namely stastions on the island adjacent to the reclamation area and two other stations in the water around the reclamation area. The results showed that the bottom sediment in the waters around the reclamation area consisted of coarse sand and medium sand with an organic matter content of 14.92% in the sediment. On the islands adjacent to the reclamation area, the bottom sediments are move varied, consisting of coarse sand, medium sand and fine sand with lower organic matter content of 4.92% to 5.38%.

Abstract

Coral spawning occurs throughout the year in Indonesia due to tropical climate conditions that influence coral development and spawning. As representative data on coral gonad development in the Spermonde Archipelago, observations on the development of the Faviidae gonads were conducted on Barrang Lompo, Kodingareng Keke, Samalona, and Bonetambung Island. Environmental elements are measured in the form of surface water temperature and rainfall. Based on the abundance of this type of gigantic coral at the study site, coral tissue sampling was concentrated on the Faviidae. The pigmentation of the gonads of Faviidae has been studied visually in nature. The samples were carved on the coral before being photographed. To make it easier to detect the level of pigmentation in each species, coral gonadal tissue was imaged. If there is an orange, yellow, or blue tint, it indicates that the coral has colored gonads and is mature gonads, indicating that coral spawning will occur soon. A water lever logger was used to measure the temperature of the water. The results of water temperature measurements vary and can be linked to the development of coral pigmentation as well as observations from November to March when the third phase (pigmented) process in Faviidae was considered to have happened in large numbers. It is possible that Faviidae can breed during this sensitive period. Rainfall data was gathered from Makassar City's Paotere Maritime Meteorological Station.

Abstract

Benthos are invertebrate animals that live at the bottom of the waters. One biota that can be used as a biological parameter in determining the quality of a waters is macrozoobenthos. The waters around the Center Point of Indonesia (CPI) are one of the waters that have received a lot of additional organic matter and other pollutant materials through the estuaries of the canals that flow into the waters of Losari Beach. The study was conducted by sampling macrozoobenthos at each station using Ejkman Grab at each station 3 times sampling then sieved using a benthos sieve measuring 1 mm. In addition, measurements of environmental factors were carried out at each station with 3 replications directly in the field and analyzed in the laboratory. The results of the macrozoobenthos sampling study obtained 4 macrozoobenthos classes found at the study site, namely the Gastropod Class (4 species), the Crustacea Class, the Ophiuroidea Class, and the Oligochaeta Class each 1 species. The highest diversity and abundance of macrozoobenthos was found at Station 6 which is suspected because this station has a sandy sediment texture and sediment DOM content and high concentrations of water solubility of oxygen which support the life of makzoobenthos. Macrozoobenthos diversity at the study site (waters around the Center Point of Indonesia) is low with a diversity index (H') value of 0.00 - 0.16. The high abundance of makzoobenthos at Station 5 and Station 6 is characterized by high current velocity, sediment DOM and high oxygen concentration.

Abstract

This study aims to detect changes in mangrove cover using 30-meter resolution Landsat imagery in 2019 and 2021 and analysis of changes in density to macrozoobenthos abundance. The research method used is the analysis of satellite imagery with NDVI transformation integrated with field surveys, the relationship between mangrove density and abundance of macrozoobenthos was tested by regression analysis. The results showed that in 1 decade (2009-2021) there was an improvement in the quality of the mangrove ecosystem with an increase in the cover of the mangrove ecosystem by 5.49 Ha, which was accompanied by an increase in mangrove density. Improvement of ecosystem conditions also affects the increase in the abundance of macrozoobenthos in substrates, roots, and stems in mangrove ecosystems even though with a small coefficient of determination.
