Indonesia is a maritime country that has a coastline that stretches for 99,093 kilometers. Mangrove ecosystems spread across Indonesia's coastal areas have an important role in providing many benefits for humans. Angke Kapuk Nature Tourism Park (TWAAK) located in North Jakarta is a conservation area managed for the preservation of mangrove ecosystems. The construction of two reclaimed islands near TWAAK in 2012 has had an impact on changing the condition of the mangrove ecosystem, especially in terms of the speed of seawater currents and sedimentation rates. This study aims to determine the composition of vegetation types and the relationship between mangrove density and sedimentation rates in the TWAAK area. The method used is vegetation analysis by applying purposive sampling techniques and the Normalized Difference Vegetation Index (NDVI) approach in determining the level of mangrove density which is divided into three categories, namely tight, medium, and rare as well as sedimentation rates to be measured using sediment trap tools. In all, 30 plots of vegetation data collection and sedimentation rates were created. Avicennia marina and Rhizophora mucronata are species that dominate the region because they have a high Importance Value Index (INP) value compared to other species. The level of mangrove species diversity in the three density classes is relatively low with a species diversity index value of less than 1. The correlation between sedimentation rate and mangrove density is positive and low (r = 0.38). The regression model estimating sedimentation rate using the vegetation density variable is significant but has a low coefficient of determination (R2 = 0.15).
