Analysis of tsunami disaster resilience in Bandar Lampung Bay Coastal Zone

Abstract

The coastal area is an area that has potential diversity of natural resources and high economic value. The coastal area is influenced by changes in land and sea so that the coastal areas are highly vulnerable to tsunami. Bandar Lampung has the potential of coastal areas of considerable potential as it is located in the bay adjacent to the Sunda Strait. Based on the study of Heru Sri Naryanto (2003), Bandar Lampung ranks third from the level of vulnerability to tsunami. Therefore, the purpose of this study to determine the readiness of the region in facing tsunami and the magnitude of the potential risks of tsunami disaster in the Gulf Coast region of Lampung in Bandar Lampung; thus, it needs to make the model or concept of tsunami disaster mitigation appropriate in terms of vulnerability and danger in creating the resilience of the Gulf Coast region of Lampung in Bandar Lampung against tsunami. The methodology used in this study was the methods of primary and secondary data collection, and the data analysis method was quantitative analysis such as spatial analysis and descriptive analysis of the data obtained from the field. The results showed that the level of preparedness in the Gulf coast region of Lampung in Bandar Lampung in facing the tsunami was still low. There are still many developed regions or houses belonging to the community either fishermen or non-fishermen located in a tsunami hazard zone. Other than that, the level of education in the Gulf coast region of Lampung in Bandar Lampung is still low where the majority of inhabitants work as fishermen. Besides, the infrastructure is old and not well-maintained so that it becomes a slum area. Therefore, the development and planning to mitigate the natural disasters tsunami using technology of IOT (Internet of Things) is an embeded system with the use of sensor seismic as a means of pre-Earthquakes vibrations, placed both on the land and in the ocean, to read the vibrations and faults in the earth’s crust under the sea. With the use of seismic sensors under the sea, the vibration of the earth’s crust under the sea will be detected. The sensors then will be connected to a flare marker buoys as a means to inform the disaster mitigation center. The construction of hall disaster at some point will be helpful to give first aid to those who are difficult to pass through the evacuation place since it is far away from the Gulf coast. The hall mitigation can be designed anti-earthquake and anti-tsunami. The model and concept of mitigation used is combining the Spatial Plan of Bandar Lampung and the mitigation of tsunami disaster as an integrated system of pre-disaster, during disaster and post-disaster by making the city of Bandar Lampung has the resilience to tsunamis.
