Daftar Isi:
- Tsunami disaster is an unpredictable natural phenomenon that can be happen anytime. Tsunami gives much destroyable in coastal area. Suffer human life, properties, and financial lost occurred in area affected by Tsunami. Risk study represent the shares which cannot release when disaster happened. This research focused at risk of Tsunami assessment in agriculture with variation of run-up height tsunami scenario at shoreline scenario. The objectives of this research were to assess Tsunami risk base on variation of Tsunami height scenario at shoreline. The assessment based on hazard spatial model and agricultural area in Bantul Regency. The specific purposes are making zonation distance maximum to land at various scenario, impact of tsunami at agriculture, and we want to know about relationship loss of agriculture with height of wave. In this research considered agriculture as element at risk. Using geo-information (RS/GIS), Tsunami risk was analyzed based on hazard, and agricultural area. Hazard class was fixed based on run-up height spatial distribution in land. Estimation of agricultural productivity was analyzed by remote sensing analysis with NDVI approach. Final result will be show in numeric and then can be multiplied by price of unhulled paddy separated from the stalks per kilograms. Result of risk calculation based on price unhulled paddy separated from the stalks at IDR. 4000, so we can make calculation of total risk are IDR. 7.406.088.000 for run up height 5m, IDR. 29.610.840.000 for 10m, IDR. 43.105.880.000 for 15m, and 47.295.600.000 for 20m. Other purpose in this research also study the risk tsunami at agriculture by various rice price and various scenario of height of wave tsunami.
