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.

Tsunami Mitigation

The coastal areas are vulnerable areas to disaster threats, especially the geological hazards of earthquakes accompanied by tsunamis. Palu City, which is located on the west coast of Sulawesi, experienced a natural disaster of an earthquake, tsunami, and liquefaction on September 28, 2018. Based on the Map of Disaster Prone Index in Central Sulawesi Province, Palu City is a tsunami-prone area that is crossed by the Palu-Koro Fault. Tsunami disaster mitigation efforts in coastal areas can be done by planting mangrove ecosystems as a green barrier. The purpose of this study is to analyze the characteristics of the coastal landscape in Palu City and plan the landscape of tsunami mitigation based on mangrove ecosystems in Palu City. The method used spatial analysis method and descriptive method, as well as the research stage, consists of preparation, data analysis, data synthesis, and landscape planning stage. The basic concept of tsunami mitigation landscape planning is to reduce or eliminate disaster risk in coastal areas based on mangrove ecosystems. The concept of spatial pattern concept consists of high hazard zones, medium hazard zones, and low hazard zones. The concept of vegetation refers to the diversity of mangrove and native plant species as green open spaces and green barriers.

Purpose – The purpose of this paper is to assess the vulnerability of the Kesennuma area in Japan to a tsunami disaster and to map the area of inundation. Design/methodology/approach – Digital elevation model (DEM) data and ALOS image were used to create maps of the parameters of this study area: elevation, slope, coastal proximity, river, and land use. An analytical hierarchy process was used to assign weights to each parameter and a spatial multi-criteria analysis was applied through cell-based modelling for vulnerability mapping. Findings – The vulnerability map shows that 17.679 km2 of the area could be inundated by a tsunami. High vulnerability areas were mostly found in coastal areas with a sloping coast and a cape area. A low elevation and the presence of rivers or water channels are factors that increase the impact of tsunamis. Inundation areas were predicted to spread in areas identified as having either high vulnerability or slightly high vulnerability. Research limitations/implications – Because of the limited geospatial data, the authors encourage further studies using DEM data with a high spatial resolution. Practical implications – The results of this research can be used as basic information for disaster mitigation and urban planning in coastal areas. Originality/value – This research creates a new approach for assessing which areas could be inundated by tsunamis, based on the vulnerability map generated through remote sensing and spatial multi-criteria analysis. Moreover, the parameters used are very close to those of actual inundation maps.

<p>The Kedukan Bukit inscription was written in 682 AD. It is considered as the oldest inscription related to the kingdom of Srivijaya and an authentic proof of the advanced maritime culture of Srivijaya. This argument is supported by the fact that, geographically, Sumatra is endowed with hundreds of large and small rivers that have generated abundant natural resources from its upstream to downstream areas. Srivijaya must have utilized these natural conditions to facilitate the distribution of its trade commodities—pepper, camphor, resin, and gold—from the upstream regions (flowing through countless tributaries to the main rivers) to the coastal areas, and even further to the various ports in Southeast Asia. Archaeological methods were used to identify and analyze a number of findings in the form of ancient boat artifacts from Srvijaya period in terms of both their respective forms and positions as they were unearthed along the Batanghari and Musi watersheds, from the upstream to estuary areas. From these findings, it can be inferred that Srivijaya managed to build a pattern of distribution network of trade commodities and to develop a sophisticated boat technology to support it. The commodity distribution network started from the upstream areas, namely the feeder points, all the way down to the downstream areas, namely the collecting centers; then, the commodities would be transported to the estuary, namely the main port of Srivijaya, and then carried to various other ports throughout Southeast Asia. The development of boat technology is the second key to the success and effectiveness of the pattern of trade commodity distribution that Srivijaya created from its upstream to downstream areas. The combination of such distribution network pattern and the development of boat technology has successfully established Srivijaya’s image as the most influential maritime power in Southeast Asia in the ancient period.</p>

Resumen: Este artículo se propone indagar sobre la relación de los sambaquíes con el medio y las evidencias que los vinculan con una cultura marítima incluyendo el posible uso de la navegación por parte de los grupos que los produjeron. Las evidencias indirectas del uso de la navegación se relacionan, entre otros, con la ubicación de los sitios en zonas costeras, la complejidad de las sociedades que los construyeron, analogías etnográficas y hallazgos de cultura material vinculada con los elementos necesarios para producir embarcaciones. A través de la serie de evidencias indirectas planteadas se pretende afirmar que esta línea de trabajo debe ser profundizada ya que puede aportar una nueva mirada a las investigaciones sobre los grupos sambaquieros y podría conducir a una reinterpretación en particular sobre su movilidad.Abstract: This paper intends to explore the relationship between shell mounds and their environment and the evidence that relates them with a maritime culture, including the possible use of navigation by the groups who built them. Indirect evidence of navigation refers, among others, to the location of sites in coastal areas, the complexity of the groups that produced them, ethnographic analogies and material culture findings related to the necessary elements for the production of watercraft. Through this series of indirect evidences, we intend to state that this topic should be explored further because it can provide a new perspective on the research of shell mound groups and could lead to new interpretations especially about their mobility.

ABSTRACT Coastal Landscape Planning in Pangandaran Based on Tsunami Disaster Mitigation The Indonesian archipelago has a long coastline of about 81,000 km. Some coastal areas in Indonesia, classified in areas with high risk of tsunami. The objective of this research was to develop a coastal planning in Pangandaran and provide recommendations related to tsunami disaster mitigation. The tsunami ever occurred at the site studied, namely in 2006. The method used in this study is a modification of the method of planning (Gold 1980) which comprise the step of preparation, inventory, analysis, synthesis, and planning. Analysis is conducted analysis of regional vulnerability to tsunamis. The results from the analysis found that Pangandaran beach is classified as an area highly vulnerable to tsunami, based on an assessment of the slope, elevation, land use, distance from the river and distance from the coast. Analysis of the suitability of the area for evacuation was conducted to determine the exact area used as a tsunami evacuation. The concept of planning is divided into space concept, the concept of activity, the concept of infrastructure, circulation concept and the concept of vegetation. The concept that there is then developed to produce a landscape plan, plan activities, circulation plan, vegetation plans, and plan infrastructure facilities.
