This research used descriptive approaches. The main variable in this research were the hue value of the Rhizophor a leaves, leaves chlorophyll content, and environmental factors (organic material, water salinity, and substrat salinity). Data was collected by purposive sampling method to identify mangrove vegetation characteristic using 100 m transect lines with three replications. The result showed that the highest dominance level was on Rhizophore stylosa (50,017%), while dominance level of Rhizophore apiculata was 49,985%. Hue value of Rhizophore leaves was in the range of86,9 0 to 141,35 0 . The lowest hue value was 86,9 0 with colour more like yellow to green where the highest value was 141,35 0 which has dark green in colour. Significant correlation only occured between hue value and water salinity, however between chlorophyll content and other environmental factors has no significant correlation. }, issn = {2721-6233}, pages = {20--26} doi = {10.14710/marj.v3i2.4839}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/4839} }
