One of the function of mangrove ecology are carbon storage as a result of photosynthesis. The results will be used as part of photosynthesis energy to plant physiology process and partly others will be included into plants structure and became part of plants, such as cellulose was stored in each section of that plant. This study aims to determine the biomass distribution and cellulose content in each part of bakau (Rhizophora mucronata) and api-api (Avicennia marina) throught the destructive sampling methods. A total of nine tress in each species were used in this study. Biomass determination will be done with measured the total wet weight of each part and then the sample of each part of tress were taken for laboratory analysis. Biomassa was divided into four compartements, i.e. stem, branches, twigs, and leaves. After that, do cellulose content examintaion with Chesson-Datta method. The results showed both of thats trees, stem biomass was the most dominant part wheread branches, twigs, and leaves contributed only a small part part of tree biomass. Biomass of Rhizophora mucronata were distributed into the stem, branches, twigs, and leaves with the proportion of 56,06%, 27,13%, 12,56%, and 4,25%. Meanwhile, the biomass of Avicennia marina were distributed into the stem, branches, twigs, and leaves with the proportion of 54,99%, 26,58%, 13,77%, and 4,66%. Based on the results of the research was known thats cellulose content in stem, branches, and twigs from both species has a value that’s not much different, except for leaves which has the smallest cellulose content. This is because, cellulose was many contained in parts of plants that have woody structures. Cellulose content of Rhizophora mucronata were contained into the stem, branches, twigs, and leaves with the proportion of 39,59%, 36,35%, 36,41%, and 31,67%. Meanwhile, the cellulose content of Avicennia marina were contained into the stem, branches, twigs, and leaves with the proportion of 37,98%, 36,03%, 36,49%, and 33,1%.
