Abstract. Syah C, Indrawan A, Priyono A. 2012. Growth of Rhizophora mucronata in mangrove restoration area at Angke Kapuk Protected Forest, Jakarta. Bonorowo Wetlands 2: 34-45. The aim of this research was to determine the plant growth rate of Rhizophora mucronata in the mangrove restoration area of Angke Kapuk Protected Forest, Jakarta, and to know the characteristics of the site and its environment. The research indicated that the average plant height was 60.388 cm to 147.496 cm and the average diameter was 2.435 cm to 6.196 cm. The average height increment of the largest, found in sub-station 1 (2.2307 cm), was significantly different from the other seven sub-stations. Average high accretion smallest sub-stations located on seven (0.1853 cm) and sub-station (0.1373cm). The average increment of the largest diameter found in sub-stations 1 (0.0591 cm) and 2 (0.0599) was significantly different from the other seven sub-stations. Average height increments are the smallest at sub-station 5 (0334 cm) and sub-station 7 (0.0334 cm), and sub-station 8 (0.0334 cm). The highest Caution exchange capacity (CEC) was found in sub-station 2 (31.55 me/100 g) and lowest in sub-station 4 (22.94 me/100 g). CEC on sub-station 4 is low because of dry soil conditions and tidal irregularities.
