Penelitian ini bertujuan untuk mengestimasi stok karbon mangrove pasca rehabilitasi di Desa Kaliwlingi, Brebes berdasarkan perbedaan tahun tanam, yakni 2005, 2008, 2011, 2014 dan 2017. Penelitian lapangan dilakukan pada 21–23 November 2020. Metode terdiri dari survei lapangan, perhitungan allometrik dan pengolahan citra Sentinel-2.

Hasil menunjukkan bahwa stok karbon mangrove tahun tanam 2005, 2008, 2011, 2014 dan 2017 secara berturut-turut adalah 80,69 tonC/ha, 95,08 tonC/ha, 104,19 tonC/ha, 175,13 tonC/ha dan 137,35 tonC/ha. Hasil analisis regresi antara nilai NDVI dan stok karbon mangrove menunjukkan koefisien determinasi yang sangat rendah (R 2 = 0,06), sehingga model tidak dapat digunakan untuk menduga stok karbon mangrove.

Mangrove as blue carbon ecosystem has a significant role in mitigating climate change which existence is threatened by land conversion. Mangrove rehabilitation has been widely done and requires sustainable management by knowing the carbon stock as a call for carbon market. The coastal area of Brebes is one of the regions that has successfully rehabilitated mangrove forest area. This research aims to estimate post-rehabilitation mangrove carbon stock in Kaliwlingi, Brebes based on different planting years, i.e. 2005, 2008, 2011, 2014 dan 2017. A field research was conducted on November 21 st – 23 rd 2020. The method involved field survey, allometric calculation and Sentinel-2 processing. A field survey was conducted to collect the diameter at breast height (DBH) of each stand and species composition. Species-specific allometric equations were used to calculate mangrove biomass, subsequently converted into carbon stock in each rehabilitated area. Sentinel-2 imagery was transformed using the Normalized Difference Vegetation Index (NDVI). Regression analysis was performed between NDVI value and carbon stock to obtain the estimation model for mangrove carbon stock using satellite imagery. There are three species found, namely Rhizophora mucronata, Avicennia alba and Avicennia marina.

Regression analysis of NDVI and carbon stock shows a very poor coefficient of determination (R 2 = 0.06), therefore the model is incompatible for estimating carbon stock. In this research, mangrove carbon stock is not increasing with plantation age.
