Abstract

The mangrove forest in the Angke Kapuk Protected Forest area is one of the mangrove forest ecosystems that is directly tied to the Java Sea, has a role in protecting coastal areas from abrasion, wind, and storms, as well as being a contributor of organic matter in estuarine ecosystems through litter fall that fell and decomposed on the forest floor. The aim of this study would be helpful to understand the productive role of mangrove forests in Jakarta, especially in the all-high tides Angke Kapuk Protecting Forest area that could be useful for sustainable conservation and management in the future. The method used to catch litterfall in the forest for a particular period of time is the litter traps method (litter trapped with nets). Traps are installed spread over the permanent plot that the size is one hectare. The trapped litterfall was sorted by leave, twig, and reproductive part, and after that baked in the oven and weighed the dry weight. Dry weight results were analyzed by comparing them with the unit time to see the litterfall's productivity rate. The dominant litterfall in this area is litterfall from Avicennia marina, the dominant species in the location. The results of this research area, first, the total annual litterfall production in the Angke Kapuk Protected Forest is around 918.02 g m-2 year-1. Second, the dominant component of mangrove litterfall in this location is the leave, which is 52% of the total litter production or around 478.19 g m-2 year-1.
