Mangrove ecosystem plays an important role in contributing the organic matter from litter produced which is a major link of the food web in mangrove ecosystem. The research was conducted to estimate litterfall production of mangroves in Tangerang coastal area. The structure and composition of the mangrove ecosystem consists of Avicenia marina, Avicenia alba, Rhizophora mucronata, and Sonneratia caseolaris with density and diameter of mangrove trees about 323 tress/100 m2 and 4.838.2 cm, respectively. The results of station groupings based on the structure and composition of mangrove with environmental parameters showed the highest production of litterfall generated by group II (station 4; consists of Avicenia marina and Rhizophora mucronata), followed by group III (station 6; consists of Sonneratia caseolaris) and group I (station 1, 2, 3, and 5; of Avicenia alba, Avicenia marina, and Rhizophora mucronata). Litterfal production of group II reached 3.86 ± 0.22 g/m2/day, followed by group III and group I (3.63 ± 2.2 g/m2/day and 2.88 ± 0.99 g/m2/day, respectively). Overall, the total production of litterfall per day in the coastal area reached 3.45 g/m2/day with leaf as the main component (>80%), followed by twigs and reproductive organs.
