ESTIMASI KANDUNGAN KARBON SERASAH DAUN MANGROVE RHIZOPHORA spp. DI HUTAN MANGROVE DESA WORI, KECAMATAN WORI, KABUPATEN MINAHASA UTARA

Abstract

ABSTRACT

               Mangroves play an important role in supporting life in coastal and marine areas. As plants that live in marine and land areas, mangrove forests transfer various kinds of nutrients both on land and into the sea. Decreasing area of mangrove forests leads to a decrease in mangrove litter production. Mangrove litter has a function as a carbon sink and storage. The purpose of this study was to determine the percentage of carbon content (C) and estimate the amount of carbon stored in the leaf litter of mangrove Rhizophora spp., in the mangrove forest of Wori Village, Wori District, North Minahasa Regency. The Litter-trap method (litter trapping net) was used in this study. Litter collection was carried out for 28 days in 12 litter-traps measuring 1x1 m². All litters trapped in the litter-trap were weighed in their wet and dry weight, then analyzed in the laboratory to determine the carbon content. Based on the results of the analysis, the total average percentage of carbon content in mangrove litter 25.93% C, and from the estimation results, the average carbon content (C) in the litter is 19.99 tons/ha/year.
