ANALYSIS OF DUNES PRESSURE AND VULNERABILITY IN TOURISM BEACH IN PANGANDARAN REGENCY, WEST JAVA

Abstract

Not only does it protect the coastline from erosion and storm surge that can pose a risk to the environment and infrastructure on land, dunes also has an important role as a habitat provider for flora and fauna. However, the increasing intensity of human activity on tourist beaches has a negative impact on dunes which can affect ecosystems, coastal resilience to storms and exacerbate coastal vulnerability. It is necessary to conduct research to analyze the vulnerability and pressure on dunes in the tourist beach area of Pangandaran Regency, West Java so that it can be an important input in maintaining the ecological balance and sustainability of this tourist beach area. The research was conducted directly on four tourist beaches, namely Batu Hiu Beach, Karang Nini Beach, Pananjung Beach, and White Sand Beach using scoring dune vulnerability assessment and euclidean algorithm approach to determine the differences in vulnerability and pressure experienced by each beach. The results show that the dunes in Karang Nini and White Sand Beach are in low vulnerability category, with the main influence coming from the physical parameters of beach conditions. Meanwhile, dunes on Batu Hiu and Pananjung Beach are in moderate vulnerability category with the dominant influence of human parameters due to their location on the side of the road, making the dunes on these two beaches more vulnerable to pressure. From the results of the study, appropriate handling is needed to reduce the vulnerability index both from physical parameters, beach conditions, and human parameters.
