Abstract

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.

Abstract

This study analyzed the composition and density of mangrove species in Borong Kalukua and Bonto Bahari in Maros Regency. The research method involved a field survey using purposive sampling in several observation plots. The data obtained were analyzed using a quantitative descriptive method to calculate the averages and standard deviations. The results showed that the mangrove density in Borong Kalukua was higher than that in Bonto Bahari, with average densities of 450 and 350 trees/ha, respectively. The standard deviation value showed variations in density between plots, with Borong Kalukua showing more significant variation than Bonto Bahari. Environmental factors and anthropogenic pressures are considered the primary causes of these differences. This study highlights the importance of conservation and rehabilitation efforts in maintaining the balance of mangrove ecosystems, particularly in areas subjected to higher environmental pressures.
