The Impact

The tsunami is the biggest threat to countries around the world tectonic plates and the ring of fire, including Indonesia. The impact of economic losses and heavy casualties made the tsunami worth watching out. Ecosystem-based tsunami disaster mitigation efforts are deemed necessary, considering that 2/3 of Indonesia consists of the sea. The coral reef is one of the coastal ecosystems that can reduce tsunami waves by up to 50% before it hits coastal areas. However, the current condition of coral reefs is very alarming due to the actions of irresponsible humans. Collaboration between stakeholders is needed to carry out ecosystem-based tsunami disaster mitigation efforts. Collaborative governance becomes an essential issue in efforts to build and improve services in the public sector by involving all relevant stakeholders. The sectoral ego of the stakeholders is no longer relevant to be maintained because each actor has their strengths and weaknesses. Collaboration between actors framed in a collaboration platform by having a principled engagement, shared motivation, and collective capacity will produce better results.

Inflatable Structure

Presented is an initial discussion on dynamic simulation of tsunami air bag deployment in connection with a number of smart inflatable and deployable structures, called tsunami air bags (TAB) that can be rather quickly set up and strongly anchored to the ocean floor to withstand the impact of a tsunami wave and thus protect the buildings and structures on shore. These dedicated inflatable smart structures are designed such that upon tsunami impact they can perform two smart deployment tasks. The first one is for the structure to deploy in the form of a porous structure containing internal folds and pockets and reconfigure due to tsunami impact to perform energy absorption by forcing the tsunami waves to pass through the porous inflatable structure forcing the tsunami waves to lose kinetic energy due to viscous drag and pressurizing the TABs. The second task is related to a special de sign of the inflatable structure that causes it to deploy to either further vertically rise or become a hollow inflatable dam upon the tsunami impact. In these endeavors a wave generation channel was designed and constructed to perform experiments and to simulate tsunami wave impacts on inflatable structures deploying from an underwater location. The initial observation indicates that TABs have a great potential to mitigate tsunami impacts.

Tsunami Disaster

Abstract Indonesia is a country located between three tectonic plates. It is the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate. The location caused Indonesia to be prone to disasters caused by the movement of plates, one of which was a tsunami. Tsunamis are high waves that hit ports or beaches. Relatively sloping beaches with low beaches can cause larger tsunami waves. This study was carried out on the coastal of Ujung Genteng, Sukabumi. The purpose of this study is to analysis the area of tsunami exposure that occurred on the coast of Ujung Genteng. GIS-based spatial modelling is used to combine different types of data, both spatial and non-spatial data to be processed into tsunami exposure area information. Modelling of the inundation was carried out with mathematical calculations developed by Berryman (2006). By modeling the tsunami with a worst-case scenario of wave height of 20 meters, it was obtained that the tsunami exposed area reached 663.29 Ha. The area belongs to a low hazard class of 2.59 Ha, a medium hazard class of 29.05 Ha, and an area that belongs to a high hazard class of 631.65 Ha. The results of this modeling are expected to be a reference for tsunami disaster mitigation planning in Ujung Genteng.

AbstractThe tsunami disaster that stroked Aceh in 2004 not only resulted in massive casualties and huge economic losses, has also resulted in massive horizontal agrarian conflicts. This article will discuss how natural disasters cause horizontal agrarian conflicts. The question that will be answered is how the tsunami caused the agrarian conflicts among the people? How such agrarian conflicts affect the reconstruction effort of after tsunami which is a series of disaster mitigation. This article uses a literature review consisting of research reports, scientific journal articles, and media reports on the impact of the 2004 Aceh tsunami. Study results and media reports suggest that the tsunami disaster resulted in the loss of boundaries of community-controlled land and this causes land disputes among neighbors that influences reconstruction efforts undertaken by governments and NGOs. However, local wisdom on conflict mitigation contributes to the settlement of land conflicts and this has contributed to post-tsunami reconstruction efforts in Aceh. With that this article contributes to the development of knowledge on disaster mitigation.   Bencana tsunami yang melanda Aceh pada tahun 2004 tidak hanya mengakibatkan banyak korban dan kerugian ekonomi yang besar, juga menyebabkan konflik agraria horisontal yang masif. Artikel ini akan membahas bagaimana bencana alam menyebabkan konflik agraria horizontal. Pertanyaan yang akan dijawab adalah bagaimana tsunami menyebabkan konflik agraria di antara masyarakat? Bagaimana konflik agraria seperti itu memengaruhi upaya rekonstruksi setelah tsunami yang merupakan serangkaian mitigasi bencana. Artikel ini menggunakan tinjauan pustaka yang terdiri dari laporan penelitian, artikel jurnal ilmiah, dan laporanmedia tentang dampak tsunami Aceh 2004. Hasil studi dan laporan media menunjukkan bahwa bencana tsunami mengakibatkan hilangnya batas-batas tanah yang dikuasai masyarakat dan ini menyebabkan perselisihan tanah di antara para tetangga yang memengaruhi upaya rekonstruksi yang dilakukan oleh pemerintah dan LSM. Namun, kearifan lokal tentang mitigasi konflik berkontribusi pada penyelesaian konflik tanah dan ini telah berkontribusi pada upaya rekonstruksi pasca-tsunami di Aceh. Dengan itu artikel ini berkontribusi pada pengembangan pengetahuan tentang mitigasi bencana.

The Impact

Disaster risk is a function of hazard and vulnerability. Risk is defined as the expected losses, including lives, personal injuries, property damages, and economic disruptions, due to a particular hazard for a given area and time period. Risk assessment is one of the key elements of a natural disaster management strategy as it allows for better disaster mitigation and preparation. It provides input for informed decision making, and increases risk awareness among decision makers and other stakeholders. Virtual globes such as Google Earth can be used as a visualization tool. Proper spatiotemporal graphical representations of the concerned risk significantly reduces the amount of effort to visualize the impact of the risk and improves the efficiency of the decision-making process to mitigate the impact of the risk. The spatiotemporal visualization of tsunami waves for disaster management process is an attractive topic in geosciences to assist investigation of areas at tsunami risk. In this paper, a method for coupling virtual globes with tsunami wave arrival time models is presented. In this process we have shown 2D+Time of tsunami waves for propagation and inundation of tsunami waves, both coastal line deformation, and the flooded areas. In addition, the worst case scenario of tsunami on Chabahar port derived from tsunami modelling is also presented using KML on google earth.

Tsunami Disaster

Indonesia coastal areas have considerable natural disaster potential including in Kalianda District South Lampung Regency. Natural disasters such as earthquakes, tsunamis and volcanic activity are likely to occur in coastal areas. The disaster has an impact on economic losses in the marine tourism area. In order to mitigate tsunami disasters in the marine tourism area of Kalianda District, South Lampung Regency, 3 (three) types of tsunami mitigation are needed, namely: construction of coastal protection, installation of the Tsunami Early Warning System (TEWS) and planting of coastal vegetation. This study aims to determine the value of willingness to pay (WTP) of community and tourists in supporting the management of the three types of tsunami disaster mitigation above by using economic valuation / Contingent Valuation Method (CVM). The results of this study indicate that the WTP value of community for coastal protection management is Rp 15.547/person/month while the WTP value of tourist is Rp 12.030/one time entry. Meanwhile, for the WTP value of TEWS management is obtained Rp 12.174/person/month. WTP value for the management of coastal vegetation is Rp 12.444/person/month. The WTP calculation is based on consideration of 3 (three) factors, namely age, income, livelyhood and education level. This research shows that the community and tourists are willing to pay for the management of the three types of tsunami disaster mitigation through BUMDes and entrance fees for marine tourism area. The three types of tsunami disaster mitigation can protect, provide security and calm to the community and tourists in the marine tourism area of Kalianda District, South Lampung Regency from future tsunami.
