Kesesuaian Rencana Pola Ruang Kabupaten Lampung Selatan Terhadap Tingkat Risiko Tsunami

Abstract

The geographical location of South Lampung Regency which is directly adjacent to the sea and active volcanoes in the ocean causes the potential for a tsunami. Tsunami hazard zones are located along the coast of South Lampung Regency with an area of ± 69,729.09 ha. At the end of 2018, South Lampung Regency was one of the areas affected by the tsunami disaster due to the avalanche of Mount Anak Krakatau which caused severe damage in 4 Districts namely Kalianda, Rajabasa, Sidomulyo, and Katibung. This study aims to determine the suitability of the spatial plan of South Lampung Regency to the level of tsunami disaster risk. This research was conducted quantitatively. Data collection was carried out by means of insti- tutional surveys, non-participatory observation, and literature review. The results showed that almost all parts of the coastal area were in the medium and high tsunami risk class. The coast includes Kalianda, Rajabasa, Katibung, Sidomulyo and Bakauheni Districts, this is due to the high threat value in these districts. Another factor that causes the 5 sub-districts to be categorized as medium and high risk is the geographical location that is directly adjacent to the sea and is a sub-district that was affected by the 2018 tsunami. Factors that affect the low risk level in the other 12 sub-districts are due to the absence of a threat value in each sub-district. . While the evaluation of the spatial plan of South Lampung Regency against the risk of tsunami disaster shows that the level of suitability of the spatial pattern plan in the 5 identified sub-districts, on average shows unsatisfactory results, the category of not quality is in the District of Rajabasa, Katibung, Sidomulyo, and Bakauheni.
