Abstract
The shape of the coastal area in each region has a different form, many factors interact and influence one another, both energy, endogenous, exogenous, extraterrial, energy materials derived from living things, including the influence of human activities. Complex marine landforms on the South Coast of West Java, one of which is in Pangandaran Regency, this can be seen from the existence of two bays bordered by a headland, each bay and headland have different landforms. Analysis of changes in land form in the coastal area can be used as input for coastal area management, considering that Pangandaran Regency has a very strong tourist attraction, which will affect land use around the coastal area. One of the objects of study is analyzing landforms, namely geomorphology and in its development the approach used is environmental oriented/environmental geomorphology. So that from the results of the analysis of marine landforms, it can be used as input for the management of the area around the coast of Pangandaran Regency. The method used in this research is descriptive method using a field survey approach and literature study. Literature analysis includes data collection on geology, climatology, hydrology, through thematic maps and journals.
The results of the research on the distribution and classification of marine landforms in Parigi Bay - Pangandaran Bay. The sedimentation process results are spit landforms on Tagog Beach, aeolian-marine sedimentation in the form of sand dunes in Parigi Bay, fluvio-marine sedimentation in the form of estuaries on Bojongsalawe Beach and tombolo in Pananjung. The landforms formed by the erosion process are stupm, notch on Batu Hiu beach, wave cut platform/abrasion platfrom in Pananjung and Karangnini beach, and stack in Pananjung. The organic-marine form of white sand is associated with reeffrom in Pananjung. Landforms resulting from sedimentation in Pangandaran, the impact is mainly the shape of the spit land covering the river estuary and the occurrence of inundation floods and even accumulation of organic waste around the coast. resistant as sedimentary rock. The management of the coastal environment of Parigi Bay – Pangandaran Bay must be carried out in an integrated manner on the northern part of the Pangandaran coast or at an altitude of 300-600 land use in harmony with soil conditions and slopes to prevent erosion, land close to the coast needs to be made of jetty retaining materials, and a wave retaining wall to minimize abrasion, for areas along the coast it is used as a vegetative-based conservative land.
