| dc.description.abstract | Mangroves play an important role in maintaining soil fertility in the
coastal area, one of the functions of mangrove forest products to maintain soil
fertility derived from the litter. Litter decomposition that have contributed to the
organic material which is a source of food for various species of fish and other
organisms in the mangrove ecosystem. The process of decomposition can be
affected by salinity, in addition to producing organic matter, litter also releases
nutrients needed by plants along the coastal area.
This study aims to determine the effect of salinity on leaf litter decomposition
rates of A. marina at different levels of salinity, nutrient content of determining
the availability of carbon (C), nitrogen (N) and phosphorus (P) contained in the
leaf litter of A. marina which decompose at different levels of salinity and know
the effect of fungi Aspergillus sp on leaf litter decomposition rates of A. marina.
The results showed that leaf litter of A. marina at the level of salinity> 20-30 ppt
decomposed faster than the rate of salinity <20-30 ppt. The average weight of
remaining leaf litter of A. marina which decompose at 00-10 ppt salinity level that
is 10.0 grams, 10-20 ppt is 11.1 grams, 9.1 grams and 20-30 ppt. A. The rate of
leaf litter decomposition marina at the level of salinity 00-10 ppt yait 0.46 grams,
10-20 ppt salinity level that is 0.43 grams, 20-30 ppt salinity level is 0.48 grams.
Nutrient content of leaf litter C A. marina is at the level of 42.32% salinity 00-10
ppt, 10-20 ppt which is 47.04%, and 20-30 ppt is 42.65%. N nutrients on leaf litter
of A. marina is at the level of 1.02% salinity 00-10 ppt, 10-20 ppt is 1.24%, and
20-30 ppt is 1.44% and leaf litter nutrient P A. marina at 0.07% salinity 00-10
ppt, 10-20 ppt is 0.09%, and 20-30 ppt is 0.09%. | en_US |
