Abstract

The diversity function of coastal areas requires the increasing need for land and infrastructure that will lead to new problems such as changes in coastal morphology, the occurrence of erosion and accretion, which is supported by the population growth caused the increasing of coastal vulnerable towards hazards. This paper aims to explain the parameters affect Simeulue Island’s coastal vulnerability - beach slope, geomorphology, geology, shoreline change, mean tidal range and mean wave height - and its mapping. The data used were the bathymetry, tide, and currents, the topography of coastal morphology, LANDSAT imagery of 2000 and 2015. To determine the coastal vulnerability level, we implemented CVI (Coastal Vulnerability Index) method of 6 parameters. Finally, we found that CVI from these physical parameters ranges between 1.291to 5.00, which were classified into five classes; 1.291 – 1.826 (very low), 1.826 – 2.449 (low), 2.449 – 2.887 (moderate), 2.887 – 3.651(high), and 3.651 – 5.00 (very high).

Abstract

The coastal area of Banda Aceh City have the potential to be polluted by waste from the mainland as much as 45.41 tons/day. One source of land waste is the Krueng Aceh river, the river has dense residential areas and high community activities such as ports, ship repairs, traditional markets, recreation and fishing activities. This study aims to identify floating debris in the Krueng Aceh estuary. Data collection was carried out at the mouth of the river using a debris trap mounted on the ship that moves periodically and the research time was based on tidal charts. The results showed that type of marine debris found is plastic, cloth, processed wood, rubber and metal. Plastic debris is the most common debris found by 89 % on the surface of the Krueng Aceh estuary at spring tide and neap tide. The highest amount of debris is found in the morning 09.50 AM and 03.32 PM in the evening.
