Sustainable reconstruction plan of abrasion affected areas based on spatial planning and risk analysis: A case study in Karawang, Indonesia
Keywords:
Abrasion, Spatial planning, Risk analysis, Sustainable constructionAbstract
One of the coastal areas in Indonesia that was severely affected by coastal erosion or abrasion in Indonesia is the North coast of Karawang. Based on observations from 1988 to 2015, the occurrence of coastal erosion along the coastline for 33.74 km, or 45.81% of the total length of 73.65 km. The area of coastal land lost due to coastal erosion reached more than 404 ha, or coastal land lost annually between 1.31 to 6.23 ha. The Department of Public Housing and Settlement Areas of Karawang Regency built a housing estate to relocate residents affected by the abrasion disaster. However, this actually creates other problems because the location is apparently in the yellow zone based on the 2017 Karawang Regency Strategic Sanitation Data. So, it is very urgent to make a reconstruction plan for an area based on space planning and risk analysis, in order to achieve sustainable construction. Assessing reconstruction solutions divided into 5 zones consist of coastal zone, buffer zone, tourism and green open space zone, low density and agriculture zone, high density housing and central business district zone.
