Potential Carbon Accumulation Rate in the Sediment Mangroves at Ujung Kulon National Park, Banten, Indonesia

As one of the wealthiest countries in the world in terms of the mangrove, Indonesia has a significant potential contributor to blue carbon. This study determines carbon stock (Corg) and sediment accumulation rate (SAR) to find the carbon accumulation rate (CAR) in sediment mangroves at Ujung Kulon National Park. Sampling was taken in 3 locations perpendicular to the shoreline: interior, fringe, and mudflat. The result shows that the interior area has the highest CAR (31.94 ± 3.6 g C m^-2 yr^-1) even though the carbon stock (90.19 Mg C ha^-1) is the lowest from the other two. On the contrary, mudflat, which has the highest carbon stock (169.6 Mg C ha^-1), shows the lowest CAR (17.03 ± 5.21 g C m^-2 yr^-1). This suggests that differences in sedimentation rates contribute to the variations in CAR.
