Rhizophora Stylosa Leaf Screen Decomposition Decomposition on Silvofishery Land in Tanjung Rejo Village, Deli Serdang Regency

Introduction

Mangrove ecosystems play a vital role in maintaining the balance of marine and terrestrial environments. These ecosystems are characterized by the presence of mangrove trees, which provide a habitat for various types of fish and other organisms. Rhizophora Stylosa, a species of mangrove tree, is an essential component of these ecosystems. The leaves of this tree serve as a food source for various organisms, including fish, and contribute to the decomposition process in the mangrove ecosystem.

The Importance of Mangrove Litter Decomposition

Mangrove litter decomposition is a complex process that involves physical and chemical changes. This process is essential for maintaining the health and fertility of the soil in mangrove ecosystems. The decomposition of mangrove litter is influenced by various factors, including temperature, salinity, and the presence of microorganisms. Fungi play a significant role in the decomposition process, contributing significantly to the breakdown of organic matter.

Research Objectives

This study aims to measure the decomposition rate of R. Stylosa leaf litter and identify the fungi species that play a role in the decomposition process. The research location was conducted in Tanjung Rejo Village, Deli Serdang Regency, where litter samples were collected and analyzed in the Land Biology Laboratory, North Sumatra University.

Methodology

The research methodology involved collecting R. Stylosa leaf litter samples from the research location and placing them in different salinity levels (0-10 ppt). The decomposition rate of the litter was measured over a period of 56 days. The fungi species present in the litter were isolated and identified using various techniques.

Results

The results of the study showed that the R. Stylosa leaf litter placed at the salinity level between 0-10 ppt experienced a relatively fast decomposition rate. The decomposition rate (K) reached more than 0.005 g/day on the 7th day, and increased significantly to 0.302 g/day on the 56th day. This finding shows that optimal salinity conditions can increase the rate of decomposition of mangrove litter, which in turn contributes to increasing soil fertility and survival of ecosystems.

Fungi Species Identification

This study identified eight fungi species that were isolated from R. Stylosa litter, which consisted of five genus, namely:

Aspergillus (3 species)
Rhizopus (2 species)
Penicillium (1 species)
Syncephalastrum (1 species)
Fusarium (1 species)

The diversity of fungi species shows that there are many microorganisms that work together in the decomposition process, which creates a better environment for plant growth and other organisms.

Conclusion

From the results of the study, it can be concluded that the decomposition rate of R. Stylosa leaf litter is strongly influenced by the condition of environmental salinity. This discovery has an important implication for silvofishery land management, especially in increasing land productivity and maintaining the balance of mangrove ecosystems. Appropriate conservation and management efforts will support the sustainability and increase in the diversity of species in this ecosystem, as well as support the economic needs of the community that depends on mangrove natural resources.

Recommendations

Based on the findings of this study, the following recommendations are made:

Conservation Efforts: Efforts should be made to conserve and protect the mangrove ecosystem, including the R. Stylosa tree.
Management Practices: Silvofishery land management practices should be implemented to maintain the balance of the ecosystem and increase land productivity.
Research and Development: Further research and development should be conducted to understand the decomposition process and the role of fungi in this process.

By implementing these recommendations, it is hoped that the sustainability and diversity of species in the mangrove ecosystem can be maintained, and the economic needs of the community that depends on mangrove natural resources can be supported.
