Analisis Produksi Karbon Serasah Mangrove di Hutan Mangrove Desa Kurau Timur Kabupaten Bangka Tengah

Abstract

Mangrove forests have many ecological functions such as holding and trapping sediment, dampening waves, providing protection for fish and other biota, and assimilating nutrients. Most of the nutrients returned to the forest floor are in the form of litter. The fallen litter will provide important organic carbon for the ecosystem. This study aims to measure the productivity and carbon content of mangrove litter in the mangrove forest of East Kurau Village. The method used to measure litter carbon production is by collecting litter using a 1m x 1m litter trap by taking litter every 7 days for 3 months, while measuring carbon content is done by the Loss on Ignition (LOI) method at 550˚C550˚C for 4 hours. Environmental parameter data analysis was carried out by PCA (Principal Component Analysis). The composition of the vegetation in the mangrove forest of East Kurau Village is 6 species which are true mangroves. The percentage of carbon content from the litter samples obtained was 53.71% with an estimated carbon production of 2.28 gr/m2/day or 6.85 tons/ha/year. The litter layer on the mangrove forest floor of East Kurau Village is with an average dry weight of 85.92 grams, a water content of 40.92%, and an estimated average biomass of 3.44 tons/ha. The environmental parameter that has the most influence on litter production is DO (oxygen content), while the carbon content of litter is more influenced by pH than any other parameter. The higher the pH in the area, the higher the litter carbon production.
