The mangrove ecosystem is very important in reducing carbon emissions because of its ability to absorb carbon. Nevertheless, contribution of carbon emissions of mangrove forests is also quite large due to the destruction of their ecosystems. Tapak Sub-village of Semarang City has typical variation of coastal ecosystems, consisting of pond ecosystem (artificial), river ecosystem (natural) and coastal ecosystem (natural). Each of these ecosystems has different structure in terms of types of plants and mangrove density. This study aims to assess the amount of biomass and carbon stocks in each type of mangrove ecosystem in coastal area of Tapak Sub-village, Semarang. Biomass measurement was conducted by allometric equations. Estimations of carbon stock was based on biomass calculation with carbon fraction as coversion factor. The results obtained showed the six research locations contributed 1507.91 ton ha-1 in mangrove biomass content, 708.20 ton C ha-1 carbon stock, and 2598.65 ton ha-1 CO2 absorption capability. The highest biomass value in each plot is from Avicennia marina contributing 913.94 ton ha-1 biomass content and 429.55 ton C ha-1 carbon content. © BIOFLUX SRL, 2017.
