Rapid urban development leads to changes of vegetation community structure in the riparian zone. Research on tree community structure has been done at 3 location points of Ciliwung riparian zone in Depok-South Jakarta with different habitat condition. Habitat at location 1 is known to be natural, habitat at location 2 has undergone land use conversion, and habitat at location 3 has undergone river bank concretization. This study aimed to compare tree community structure in the 3 locations. We used plot method for data sampling. A total of 4 plots at each location with size of 20x20 m were determined purposively. The results showed that the 3 locations showed differences in the tree community structure. Compositions of tree at location 1, 2, and 3 respectively consists of 11 species in 8 families, 14 species in 10 families, and 4 species in 4 families. Overall, all three locations have low to moderate level of tree diversity (H' 1.26-2.3) and high level of tree evenness (E 0.81-0.90). Based on Importance Value (IVi), location 1, 2, and 3 respectively are dominated by species of Cecropia peltata (85.12 %), Paraserianthes falcataria (142.40 %), and Leucaena leucocephala (105.94 %). © 2021 Journal of Physics: Conference Series.
