Estimation of Organic Content and Carbon Uptake in Sonneratia alba (Smith) Mangroves in Aquaculture Areas: a Case Study in the Marine and Brackish Water Cultivation Area of Probolinggo City, Indonesia

This study aims to analyze the value of organic carbon content and CO₂ uptake in the leaves, roots and sediments of Sonneratia alba mangroves. The research location was in the area of ​ Marine and Brackish Water Cultivation area of ​Probolinggo City. The research method used was a survey method and the sampling was done by a non-destructive method. The results show that the highest average biomass value in the leaves, roots, and sediments respectively is in the ratio of 7: 8: 9. The highest average carbon content value in the leaves, roots, and sediments respectively is the ratio of 14: 17: 1. The conclusion in this study is that the carbon content in each component of the leaves, roots and sediments is 20.72 g. m^-2, 24.76 g. m^-2, 1.49 g. m^-2, respectively and the carbon dioxide uptake in the leaves, roots, and sediments is 90.80 g. m^-2, 75.98 g. m^-2, 5.46 g. m^-2 with a ratio of 14: 17: 1.
