Abstract:
The coastal area of Tanjung Dewa Village in the Panyipatan subdistrict of the Tanah
Laut regency exhibits different physical geomorphological typologies. These conditions affect the
diversity of community activities, as well as the area's environmental potential and issues. The
environmental issues most commonly found in the research location are coastal erosion and tidal
flooding. This study aims to analyse the physical typology of the coast based on geomorphology,
to inform coastal management and development planning in Tanjung Dewa Village. This study
employed a qualitative geomorphological approach to collect primary data through field surveys,
landform and coastline documentation, literatures review and interviews with local village officials.
Secondary data from remote sensing imagery, geological maps and slope data were used to
supplement the analysis. The analysis revealed three typological categories: volcanic coast,
marine deposition coast and sub-aerial deposition coast. The findings describe differences in
landform and coastal types within a narrow area. Each type of coastal type has different
environmental issues depending on the geomorphological processes that occur. This difference
certainly affects the type of environmental management. The type of coastal management
required differs according to the typology: for example, wave barriers and coastal protection
structures are built on volcanic coasts, mangroves are rehabilitated for coastal protection on sub
aerial deposition coasts, and local regulations are drafted for monitoring and protecting coastal
and riverine areas.
