Abstract

Cirebon is one of the coastal areas that has very potential mangrove areas. The existence of mangroves in this area has an important role for the survival of other ecosystems, but the type of mangrove vegetation has not yet been identified. The aim of this research is to determine the type of mangrove vegetation in one of the coastal areas of Cirebon Regency, namely in the Kasih Sayang Mangrove Zone, Mundu Pesisir Village. Importance values, relative density, relative frequency, and relative dominance obtained from vegetation analysis are used as indicators to describe the structure of mangrove vegetation. To support this research, water quality measurements (temperature, pH, dissolved oxygen and salinity) were carried out in situ in mangrove forests. This research was conducted from July to August 2023. This research was conducted using the Purposive Sampling method. The research results show that there are 4 types of mangroves, namely Rhizopora mucronata, Bruguiera, Xylocarpus Granatum, and Avicennia marina. Based on the importance value analysis, it shows that the Rhizopora mucronata species has the highest importance value compared to other species, namely 154.17%. The condition of water quality in the Mundu Coast, Cirebon district, is still considered adequate to support the life and development of mangroves.

Abstract

This study aims to analyze the Importance Value Index (INP) of mangrove vegetation in the Purwawinangun Village area, Suranenggala Subdistrict, Cirebon Regency. The research was conducted over a period of three months, from June to August 2023, with the study area divided into three observation sites based on specific geographic coordinates. A survey approach was employed using purposive sampling. Vegetation data were collected using the transect line plot method and subsequently analyzed to determine the INP for each mangrove species. The results revealed that the mangrove species with the highest density, in descending order, were Avicennia marina (7,666.67 trees/ha), Acanthus ilicifolius (2,300 trees/ha), Rhizophora mucronata (900 trees/ha), Pluchea indica (666.67 trees/ha), Sonneratia caseolaris (300 trees/ha), and both Leucaena leucocephala and Jatropha curcas L. (66.67 trees/ha each). Rhizophora mucronata recorded the highest frequency (37.5%), highest relative canopy cover (53.10%), and a canopy closure value of 0.96. This species also exhibited the highest INP at 95.58%, while Leucaena leucocephala had the lowest at 8.32%. These findings indicate that Rhizophora mucronata ecologically dominates the mangrove community in the study area. Its dominance is attributed to its strong adaptability to varying salinity levels, water depth, and muddy soil characteristics. This species plays a crucial role in sustaining mangrove ecosystem resilience and provides significant ecological benefits for coastal protection against erosion and climate-related changes.
