Strategi Penataan Ruang Berbasis Mitigasi Bencana Berdasarkan Tingkat Kerentanan dan Bahaya Banjir Rob di Kota Bandar Lampung

Abstract

Indonesia’s geographic location, which is in a disaster-prone area, requires a spatial planning strategy based on disaster mitigation as an effort to improve the safety and comfort of life for its people. Bandar Lampung City is one of the cities that has a coastal area facing Lampung Bay with a coastline of 27.01 Km. Tidal flooding is a disaster that threatens coastal areas due to climate change. Every year, tidal floods occur at least three times a year with inundation duration of more than three hours or even one week. Tidal flooding in the coastal area of Bandar Lampung City has a hazard classification from low to high which is categorized based on the height of the flood inundation. In each kelurahan the height of the flood varies from a height of less than 50 cm to more than three meters. Regional vulnerability is one of the weaknesses that must be addressed in order to reduce the risk of tidal flooding. Based on the results of the vulnerability analysis, three urban villages in the coastal area are classified into a moderate level of vulnerability. The most influential sub-indicators are physical and social vulnerability. In reducing the level of vulnerability, it is necessary to formulate a strategy with a mitigation-based spatial planning approach using a SWOT analysis. The formulation of the strategy is carried out by connecting the linkages between internal and external factors in the area through a spatial planning approach in the form of spatial planning, space utilization and spatial use control. Spatial planning plays a role in the development and prevention stages of tidal flooding that threatens the coastal area of Bandar Lampung City in order to create safe, comfortable, productive and sustainable spatial activities.
