Abstract:
Mangrove forests have ecological functions as an absorber of carbon dioxide and store carbon
through photosynthesis. How much carbon stored in mangrove forest can be estimated by
biomass contained as an individual constituent mangrove forest vegetation. This research
aims to develop allometric model to estimate content of biomass on Rhizophora apiculata
which is one of the compilers specific of the mangrove forest. Research methods through
logging (destruction) with a total sample of 35 trees that represents the distribution diameter
of 11-78 cm. The results showed content of the biomass species Rhizophora apiculata as
much as 77% on the trunk, 14% on the branch, 6% on the twigs and 3% on the leaves.
Allometric are obtained to estimate the biomass content on Rhizophora apiculata types are as
follows: Y = 0,1488D2,4310; branch section Y = 0.0229D2,4521; twigs part Y = 0.0375D2,0389;
leaf Y = 0.1898D1,2809; total tree Y = 0.2300D2,3766. Through determination test concluded
that the allometric chosen is Y = 0.2300D2,3766 with the value of the determinant coefficient of
0.9479
