Rhizophora Apiculata Leaf Litter Decomposition Rate and Contribution to Nutrients in the Waters of Pulau Sembilan, Pangkalan Susu District, Langkat Regency

Introduction

Mangrove ecosystems play a vital role in maintaining the balance of aquatic ecosystems, and the Rhizophora Apiculata mangrove leaf litter decomposition is a crucial process that contributes to the nutrient cycle in these ecosystems. The decomposition of R. Apiculata leaf litter releases essential nutrients such as carbon (C), nitrogen (N), and phosphorus (P), which are vital for the survival of various organisms living in and around the mangrove area. This study aims to determine the R. Apiculata leaf litter decomposition rate and the nutritional content released during the decomposition process in the waters of Pulau Sembilan, Pangkalan Susu District, Langkat Regency.

Background

Mangrove ecosystems are complex and dynamic environments that support a wide range of plant and animal species. The Rhizophora Apiculata mangrove is one of the most common species found in these ecosystems, and its leaf litter is an essential component of the nutrient cycle. The decomposition of R. Apiculata leaf litter is influenced by various environmental factors, including water currents, salinity, and the diversity of decomposing organisms. Understanding the decomposition rate and nutritional content of R. Apiculata leaf litter is crucial for maintaining the health of mangrove ecosystems and conserving the biodiversity of these areas.

Methodology

This study was conducted from March to June 2016 in the waters of Pulau Sembilan, Pangkalan Susu District, Langkat Regency. A purposive sampling method was used to select three stations based on the availability of R. Apiculata. The decomposition rate of R. Apiculata leaf litter was measured at each station, and the nutritional content, including carbon (C), nitrogen (N), and phosphorus (P), was analyzed after 75 days of decomposition.

Results

The results of this study showed that the R. Apiculata leaf litter decomposition rate varies at each station. On the 75th day, station I recorded the highest decomposition rate of 10.18, followed by station II with 8.58, and station III with 8.53. This data indicates that environmental factors such as water currents, salinity, and the diversity of decomposing organisms in each station play an important role in influencing decomposition speed.

In addition to the decomposition rate, nutritional content analysis is also very interesting to observe. The carbon content after 75 days of decomposition is 17.41% at stations I and III, and 15.84% at station II. This indicates that although there are differences in the rate of decomposition, carbon content remains relatively stable. For nitrogen content, stations I and II showed a value of 0.98% and 1.18%, while station III also recorded 1.18%. As for phosphorus, station I has a content of 0.08%, station II 0.09%, and station III 0.10%.

Discussion

The contribution of nutrients from R. Apiculata leaf litter decomposition is very significant for aquatic ecosystems. Nutrient elements released during the decomposition process can be utilized by various organisms, especially fish and other organisms that live around the mangrove area. The existence of this litter is not only a source of nutrition, but also as a habitat and a breeding place for many species.

The results of this study emphasize the importance of conservation of mangrove areas to maintain the balance of ecosystems and increase the survival of species that depend on the environment. The decomposition rate and nutritional content of R. Apiculata leaf litter are crucial factors that influence the health of mangrove ecosystems. Therefore, it is essential to continue research and conservation efforts to maintain the health of mangrove ecosystems, including in the waters of Pulau Sembilan.

Conclusion

In conclusion, this study provides valuable information on the R. Apiculata leaf litter decomposition rate and nutritional content in the waters of Pulau Sembilan, Pangkalan Susu District, Langkat Regency. The results of this study highlight the importance of conservation of mangrove areas and the need for continued research and conservation efforts to maintain the health of mangrove ecosystems. The decomposition rate and nutritional content of R. Apiculata leaf litter are crucial factors that influence the health of mangrove ecosystems, and understanding these factors is essential for maintaining the balance of ecosystems and increasing the survival of species that depend on the environment.
