| dc.description.abstract | The mangrove forest ecosystem plays an absorbent and carbon sink to reduce CO2
levels in the atmosphere, including in degraded mangrove areas. This research was conducted
precisely on abandoned shrimp ponds in mangrove areas in the Mahakam Delta. Four different
locations are locating on Sepatin ponds, ponds, ponds, and ponds Bayur headland. The purpose
of this study was to estimate the above-ground carbon stock in abandoned shrimp ponds. Carbon
stock measurement methods create a 125 m transect and quadrant divided into six plots at each
location. These measurements were conducted on living vegetation and dead wood from felling
vegetation. Measurement of above-ground biomass was done by measuring the tree diameter at
breast height (1.3 m) on each tree diameter> 5 cm in radius quadrant plot 7 m. Vegetation has a
diameter <5 cm categorized in seedling criteria and measured 30 cm from the ground within the
quadrant plot radius of 2 m. The vegetation diversity experienced a succession calculated using
the diversity index by calculating the dominance index, diversity index, and similarity index of
vegetation. While the calculation of above-ground biomass accumulation using allometric
equations according to the species. The results showed that vegetation analysis in the fourth
study sites obtained a high dominance index value at each location. The study is inversely
proportional to the value of diversity and similarity index. The highest total carbon stock at
Tanjung Nipah location was 11.599 Mg C. Ha-1
, followed by Sepatin 6.248 Mg C. Ha-1
, Benati
Dalam 3.579 Mg C. Ha-1
, and lowest carbon stock at Bayur location 1.460 Mg C. Ha-1
