Stability analysis of mangrove forest resource depletion models due to the opening of fish pond land

The existence of Mangrove Forest is very necessary for the cycle of the food chain of marine fauna and its ecosystem. Balikpapan City has several Mangrove forest conservation areas that contain some rare – protected species. In this paper, a mathematical model is formulated to examine the problem of decreasing Mangrove forest resources due to the population of Bekantan (Nasalis larvatus), and the land clearing for fish ponds in the area of Mangrove forest conservation areas. The cumulative density of Mangrove forest resources and density of Bekantan (Nasalis larvatus) are assumed to follow the logistic model with predator-prey types of non-linear interactions. The main focus of this paper is to develop a Mangrove forest model derived from assumptions on the forest resource model and direct observation in the Mangrove Graha Indah forest conservation area of Balikpapan city. Furthermore, the model was analyzed using the stability theory of differential equations and numerical simulations to obtain an illustration that the cumulative density of Mangrove forest resources and Bekantan (Nasalis larvatus) would be significantly decreased if the land clearing for fishponds was not controlled.

PERSEPSI MASYARAKAT TERHADAP KEBERADAAN HUTAN MANGROVE DI DUSUN SETINGGA ASIN DESA SEBUBUS KECAMATAN PALOH KABUPATEN SAMBAS

Mangrove forests are tropical coastal vegetation communities, which are dominated by several types of mangrove trees that are able to grow and develop in muddy coastal tidal areas. In order to preserve the biological and ecological functions of the mangrove forest ecosystem, a rational approach is needed in which a rational approach in its utilization involves communities around the area. Hamlet of Setingga Asin Sebubus Village, Paloh Subdistrict, Sambas Regency is one of the hamlets that has a mangrove forest area. The majority of the hamlet Setingga Asin people live as farmers, entrepreneurs and fishermen. People around the forest use it as additional livelihoods such as searching for shrimp, crabs, shellfish, kepah and nipah as the main ingredients for making roofs. The existence of the relationship between the community and the existence of mangrove forests raises the perception of the community in an effort to maintain and preserve the existence of the mangrove forest itself. Therefore, this study aims to determine the public perception of the existence of mangrove forests in Hamlet of Setingga Asin, Sebubus Village, Paloh Subdistrict, Sambas Regency and to know the factors that influence people's perceptions. The study used a survey method with interview techniques for 73 family heads in Hamlet Setingga Asin. Sampling of respondents is done by purposive sampling technique. The data analysis used was descriptive analysis and inferential analysis of the Kendall Tau correlation. The results showed that community perceptions of the existence of mangrove forest in hamlet Setingga Asin, Sebubus Village, Paloh Subdistrict, Sambas Regency tend to be neutral, this is because the community basically realizes that they depend on the surrounding mangrove forest's biological resources.

Coastal erosion due to long-term human impact on mangrove forests

A coast in southern Vietnam, which is located in a wide and flat alluvial fan and neighbors tidal rivers fringed by wide mangrove swamps, has been eroded continuously by approximately 50 m/year since the early 20th century. Based on field observations and numerical experiments, it is inferred that this large scale erosion is caused by the transition of mangrove vegetation resulting from the long-term impact of humans since the late 19th century. This eroded coast is not in direct contact with mangrove swamps, but is strongly affected by the existence of mangrove forests through the intermediation of neighboring tidal rivers. Thus, with a view to coastal protection, it is argued that the mangrove vegetation in adjacent areas should be managed more sensitively.
