      Abstract
      Hutan mangrove mempunyai potensi mitigasi perubahan iklim karena kemampuannya dalam menyerap dan menyimpan karbon dalam waktu lama dan dalam jumlah besar. Adanya alih fungsi lahan dapat merubah komposisi vegetasi hutan mangrove dan mengurangi simpanan karbon. Penelitian ini bertujuan untuk mengetahui komposisi vegetasi pada kawasan ekowisata mangrove Karangsong dan mengetahui kemampuan mangrove dalam menyerap serta menyimpan karbon. Metode dalam penelitian ini yaitu jalur garis berpetak pada 10 titik stasiun pengamatan yang dianggap mewakili keseluruhan karakteristik vegetasi dengan total intensitas sampling sebesar 5%. Analisis kandungan karbon dilakukan menggunakan persamaan alometrik. Dari hasil analisis vegetasi terdapat 4 jenis mangrove, yiatu Avicennia marina, Avicennia alba, Rhizophora stylosa, Rhizophora mucronata. Total biomassa, kandungan karbon dan simpanan karbon dioksida seluruh kawasan seluas 20 ha yaitu beturut-turut sebesar 99,14 ton/ha; 46,6 tonC/ha; 171 tonCO2 /ha. Besarnya kandungan karbon yang tersimpan di kawasan ekowisata Mangrove Karangsong dipengaruhi oleh faktor lingkungan yang terbentuk pada tegakan mangrove.
       
      Mangrove forests have the potential to mitigate climate change because of their ability to absorb and store carbon for a long time and in large quantities. The existence of land use change can change the composition of mangrove forest vegetation and reduce carbon sequestration. This study aims to determine the composition of vegetation in the Karangsong mangrove ecotourism area and to determine the ability of mangroves to absorb and store carbon. The method in this study was a line transect plot at 10 points of observation stations which are considered to represent the overall characteristics of the vegetation, the total sampling intensity is 5%. Carbon content analysis was carried out using allometric equations. From the results of the vegetation analysis, there were 4 types of mangroves, namely Avicennia marina, Avicennia alba, Rhizophora stylosa, and Rhizophora mucronata. The total biomass, carbon content, and carbon dioxide uptake in the entire area of 20 ha are 99.14 tons/ha; 46.6 tonsC/ha; and 171 tonsCO2/ha, respectively. The amount of carbon stored in the Karangsong Mangrove ecotourism area was influenced by environmental factors formed in the mangrove stands.
