Mangroves are plants that are able to survive in coastal areas under environmental conditions
that are influenced by tides and muddy seawater. Mangrove forests have an ecological function, which
is to play a role in efforts to mitigate global warming because mangrove forests absorb and store carbon
dioxide (CO2) which is carried out through the process of photosynthesis and storing it in biomass stock.
There are 2 objectives of this study, namely: (1) to estimate the carbon stored in mangrove vegetation
in Likupang District, North Minahasa Regency (2) to find out how much potential carbon stock is stored
in mangrove vegetation and absorption of carbon dioxide (CO2) on mangrove stands. The method used
in this study was a sample plot transect line (Dharmawan and Pramudji, 2001). Based on the results
obtained from the calculation of the biomass and carbon stock stored in mangrove vegetation in
Likupang District, North Minahasa Regency, it can be seen that the average value is 452.42 tons/ha
with a carbon content or the amount of carbon stored is 212.64 tons C/ ha or equivalent to 780.38 tons
of CO2/ha.Keywords: Mangrove Vegetation, Carbon, North Minahasa
ABSTRAK
Mangrove merupakan tumbuhan yang mampu bertahan hidup di daerah pesisir pantai dengan
di bawah kondisi lingkungan yang dipengaruhi oleh pasang surut air laut dan berlumpur. Hutan
mangrove memiliki salah satu fungsi ekologis yaitu berperan dalam upaya mitigasi pemanasan global
karena hutan mangrove sebagai penyerap dan penyimpan karbon dioksida (CO2) yang dilakukan
melalui proses fotosintesis dan menyimpannya dalam stok biomassa. Tujuan dari penelitian ini ada 2
yaitu: (1) mengestimasi karbon tersimpan pada vegetasi mangrove di Kecamatan Likupang, Kabupaten
Minahasa Utara, dan (2) mengetahui berapa besar potensi stok karbon tersimpan pada vegetasi
mangrove dan serapan karbondioksida (CO2) atas tegakan mangrove. Metode yang digunakan dalam
penelitian ini adalah garis transek petak contoh (Dharmawan dan Pramudji, 2001). Berdasarkan hasil
yang diperoleh dari perhitungan biomassa dan stok karbon yang tersimpan pada vegetasi mangrove di
Kecamatan Likupang, Kabupaten Minahasa Utara, dapat nilai rata-rata sebesar 452,42 ton/ha dengan
kandungan karbon atau jumlah karbon tersimpan sebesar 212,64 ton C/ha atau setara 780,38 ton
CO2/ha.
