Effect of River Organic Carbon Input in Mangrove Sediment
No full textMangrove is a coastal ecosystem that absorbs and stores carbon as organic carbon in sediment. The high value of organic carbon in mangrove sediment is influenced by one factor: organic input from the river. This study aims to analyze the effect of the river's total organic carbon (TOC) on TOC stored in mangrove sediment. The samples used were water samples analyzed by the TOC analysis method and sediment samples taken at a depth of 20 cm and analyzed by the combustion method using a C-N analyzer and measuring oceanographic parameters at the research location. The results showed that TOC in the Bakau Kecil River was higher (79 mg/L) compared to TOC in the Bakau Besar River (66.36 mg/L). This is based on the finding of the highest TOC in the Bakau Kecil River mangrove sediment compared to Bakau Besar, with values of 840.14 tons C/ha and 698.86 tons C/ha, respectively. However, regression analysis showed a negative relationship between TOC in mangrove sediment and TOC in waters. If TOC in the river increases, then TOC in sediment tends to decrease. In addition, oceanographic parameters that affect TOC are tides. When TOC rises, TOC is more significant than when TOC recedes.Ekosistem mangrove dapat dijadikan sebagai alternatif untuk membantu upaya mitigasi perubahan iklim. Tingginya nilai karbon organik pada sedimen mangrove dipengaruhi oleh beberapa faktor, yaitu masukan organik dari sungai. Sungai merupakan perairan yang membawa masukan organik dari daratan menuju pesisir pantai dan mengalir ke hutan mangrove. Penelitian ini bertujuan untuk melihat pengaruh total karbon organik terhadap stok karbon organik sedimen. Sampel yang digunakan adalah sampel air, kemudian dianalisis menggunakan metode LOI (Los on Ignition). Sampel sedimen diambil pada kedalaman 20 cm dan dianalisis dengan metode pembakaran menggunakan C-N analyzer serta pengukuran parameter oseanografi di lokasi penelitian. Hasil penelitian menunjukkan bahwa total karbon organik di Sungai Bakau Kecil lebih tinggi (79 mg/l) dibandingkan dengan total karbon organik di Sungai Bakau Besar (66,36). Hal ini sesuai dengan temuan stok karbon organik mangrove tertinggi di Sungai Bakau Kecil dibandingkan dengan Stok Karbon Organik Bakau Besar dengan nilai masing-masing sebesar 840,14 ton C/ha dan 698,86 ton C/ha. Salah satu penyebabnya adalah masukan karbon organik dari sungai yang berasal dari pemukiman. Selain itu, pasang surut disebabkan oleh adanya pencampuran di sekitar muara sungai. Oleh karena itu, penelitian ini diharapkan dapat memberikan pemahaman tentang pengaruh masukan sungai terhadap stok karbon dalam sedimen
