Estimasi nilai stok karbon mangrove di Kawasan Ekowisata Mangrove Ketapang Urban Aquaculture, Kabupaten Tangerang

Abstract

Pemanasan global merupakan fenomena alam terjadinya peningkatan suhu rata-rata atmosfer bumi. Terjadinya pemanasan global disebabkan karena peningkatan kadar gas rumah kaca salah satunya gas karbon dioksida (CO2) akibat pembakaran bahan bakar fosil, polusi industri, polusi transportasi. Salah satu solusi untuk mengurangi emisi gas CO2 melalui pelestarian ekosistem mangrove yang memiliki kemampuan dalam menyerap dan menyimpan karbon. Penelitian ini bertujuan untuk menduga nilai stok karbon mangrove di kawasan ekowisata mangrove Ketapang Urban Aquaculture, Kabupaten Tangerang. Sampel diambil menggunakan metode purposive sampling. Sampel sedimen diambil sedalam 30 cm menggunakan pipa akrilik. Hasil penelitian menunjukkan kondisi ekosistem mangrove di Kawasan memiliki kerapatan yang sangat tinggi, rerata nilai estimasi nilai stok karbon mangrove sebesar 23,25 ton C/ha dan serapan karbon sebesar 85,24 ton CO2/ha, serta simpanan karbon dalam sedimen sebesar 4.327 ton C/ha.

Global warming is a natural phenomenon of an increase in the average temperature of the earth's atmosphere. Global warming is caused by an increase in greenhouse gas levels, one of which is carbon dioxide (CO2) gas due to fossil fuel combustion, industrial pollution, transportation pollution. One solution to reduce gas CO2 emissions is through the preservation of mangrove ecosystems that have the ability to absorb and store carbon. This study aims to estimate the value of carbon stock in mangroves in the Ketapang Urban Aquaculture mangrove ecotourism area, Tangerang Regency. Samples were taken using purposive sampling method. Sediment samples were taken 30 cm deep using acrylic pipes. The results showed that the condition of the mangrove ecosystem in the area had a very high density, the average estimated value of mangrove carbon stock value was 23,25 ton C/ha and carbon uptake was 85,24 ton CO2/ha, and carbon storage in sediments was 4.327 ton C/ha.
