| Summary: | Angke Kapuk Mangrove Tourism Park, as part of the Angke Kapuk Protected Forest area, is a nature conservation area that is also used for ecotourism. This area is a wetland dominated by mangrove vegetation, especially the genus Rhizophora and Avicennia. From its history, this area was once used as a shrimp farm. Knowing it’s history and current conditions, it can be estimated that a silvofishery pond system can be developed in this area to increase its economic and ecological value. Mangrove ecosystems are often used as the basis for silvofishery pond management systems because of the resistance of mangroves to saltwater and their role in the process of nutrient cycling. Nutrients are dropped in the form of litter which then feeds the biota below. This study aims to calculate litter production and litter decomposition rate as nutrient intake in the silvofishery pond system that will be designed in the Angke Kapuk Mangrove Tourism Park area. The research was conducted from March to May 2018. Litter production data was taken from litter which fell into a 50x50 cm2 litter trap on three different sites, while litter decomposition rate data was taken using litter bags (5 mm mesh size) by adding 5 grams of fresh leaf litter which is then placed on the forest floor for 10 weeks. Litter samples are taken every two weeks. The results showed that litter production in the area was 24.88 tons ha-1 year-1. The Rhizophora plant contributed 12.46 tons ha-1 year-1 of litter while the Avicennia genus was 10.73 tons ha-1 year-1. The litter decomposition rate for 10 weeks of observation was 0.14 grams per day for the genus Rhizophora and 0.12 grams per day for the genus Avicennia.
