Efficiency of Rhizophora apiculata in absorbing CO2 and biomass production was conducted from Rhizophora apiculata stand with an age of 4 years density of 9 stems/square m. Rhizophora apiculata stand were planted in green house. Matured and sun leaf were used for CO2 absorbing measurement using portable photosynthetic system (LCA4) and leaf area index measurement using sunfleck ceptometer. Stem diameter, height, fresh weight and dry weight of root, stem, branch and leaf were collected for determination of biomass production. Average of CO2 absorption rate of Rhizophora apiculata was 4.63 micro mol/square m/s at 337 micro mol/square m/s of PAR concentration. The maximum rate of CO2 absorption was 9.47 micro mol/square m/s at 725 micro mol/square m/s of PAR concentration. Biomass production using Pn(a) = Pn(t) - Lp, indicated that Rhizophora apiculata production at age of 4 years growing in the green house was 3.037 tons/rai/year.
