Mangrove ecosystems play an important role in mitigating global warming through their ability to absorb and store carbon in biomass and sediment. This research analyzes the organic carbon content and carbon sequestration potential in mangrove sediments in Bonto Bahari, Maros Regency, South Sulawesi. Using purposive sampling method, sediment samples were taken from 9 points with 5 different depths (0-50 cm) and analyzed using the Loss on Ignition (LOI) method. The results showed very low bulk density values (0.01-0.02 g/cm³) with the highest value at a depth of 20-30 cm. Carbon concentrations were relatively uniform (1.5-2.0%) at all depths with the highest concentration at a depth of 40-50 cm (1.93%). The highest carbon content was found at a depth of 40-50 cm (100.667 tons/ha) with carbon sequestration reaching 516.958 tons/ha, while the lowest value was at a depth of 0-10 cm (24.60 tons/ha). There were significant differences (p<0.05) in carbon content and sequestration between depths of 0-10 cm and 20-30 cm. This research reveals that deeper sediment layers play an important role in carbon storage in mangrove ecosystems, providing significant implications for sustainable mangrove management and local ecosystem-based climate change mitigation efforts

Mangrove ecosystems are essential in mitigating climate change through Carbon storage in sediments. This study aims to analyze the bulk density values, carbon concentration, and Carbon storage and absorption in mangrove sediments in Borongkalukua, Maros Regency. Sampling was carried out at five sediment depths (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm) using the Loss on Ignition (LOI) method and analyzed statistically using one-way and two-way ANOVA. The results showed an average bulk density value of 0.33 g/cm³, with the highest value at a depth of 30-40 cm (0.28 g/cm³). Furthermore, the average Carbon concentration was 11.37%, with the highest value at a depth of 40-50 cm (20.50%) and the lowest at 0-10 cm (1.98%), with no significant differences between depths (p-value > 0.05). Meanwhile, Carbon storage in sediment reached 2,423.77 tons/ha. Total absorption reaching 8,895.23 tons/ha. In conclusion, sediment depth affects carbon accumulation, with higher carbon content in deeper layers due to the sedimentation process and minimal decomposition. This study emphasizes the importance of mangrove conservation in supporting Carbon storage and climate change mitigation.

Climate change and global warming cause massive damage to the environment. One of the major events that arethreatening the marine ecosystem is coral bleaching. Coral bleaching occurs when corals are exposed to above or belownormal temperatures. The aims of this study are to compare the resistance of Isopora palifera and Acropora hyacinthusfrom Karanrang Island to temperature stress. Four treatment temperatures (28ºC, 30ºC, 32ºC, and 34ºC) were tested toassess the role of temperature stress and bleaching to Isopora palifera and Acropora hyacinthus for 48-hours. Theabundance of zooxanthellae counted as the temperature stress variable. The results showed that there was a difference ofcoral response tothe treatment based on the time of experiment, after 48-hours experimentexposed at temperaturetreatment of 34°C the abundance of zooxanthellae from Isopora paliferawas 0,06 x105 cm-2 and the abundance ofzooxanthellae from Acropora hyacinthus is 0,18 x105cm-2. In comparison between species, Isoporapalifera taken fromKaranrang Island was more resistant to temperature stress thanAcroporahyacinthus.

Plastics become debris in the ocean that can be broken down into tiny particles of micro size (<5 mm) and scattered into columns to the bottom of the water. Its very small size makes it easily accessible to various aquatic organisms, such as plankton, crustacean, and mussel. There have been many studies use mussel as a bioindicator for microplastic pollution but no one has observed the effect of microplastic exposure to mussel mortality. The aim of study was to examine the effect of microplastic on mussel mortality. Green mussels were collected from Mandalle Waters, Pangkep Regency (Pangkajene Kepualauan) then were exposed to microplastic polyethylene originating from shieving of scrub soap. The exposure was carried out for 7 days with microplastic concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. Statistical test results showed the treatment B and C were not significantly different, but the two treatment were significantly different from treatment A. The percentage of green mussel mortality during the experiment increased with increasing microplastic concentrations with the percentage of mortality exceeding 80% at treatment C.

Global warming represents a significant challenge, primarily driven by the escalating concentrations of greenhouse gases in the atmosphere, notably carbon dioxide (CO₂). Mangrove ecosystems are integral to climate change mitigation due to their capacity to sequester and store carbon within their biomass and sediment. This study sought to evaluate carbon sequestration through the analysis of organic carbon content in the sediments of mangrove ecosystems located in Ampekale, Maros Regency. Sampling was executed using a purposive sampling method across nine sites, employing a 50 × 5 cm corer. Each sediment sample was sectioned into five depth intervals (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm). The organic carbon content was assessed using the loss on ignition (LOI) method, with parameters measured including bulk density, sediment organic carbon concentration, carbon storage, and carbon uptake in sediments. Statistical analyses were conducted utilizing one-way and two-way ANOVA tests. The findings indicated that the mangrove ecosystem in Ampekale exhibited a total carbon storage in sediments of 731.72 tons/ha, with a total carbon uptake of 2685.42 tons/ha. The greatest carbon storage and uptake were observed at the 40-50 cm depth, with values of 342.056 tons/ha and 1255.34 tons/ha, respectively.
