The Analysis of Tsunami Risk Based on The Building Vulnerability and Community Preparedness in Kuta Alam Sub-District Banda Aceh

The tsunami in 2004 had devastated many thousands of houses in Banda Aceh City. The worst damage occurred in Meuraxa, Kuta Raja, Syiah Kuala and Kuta Alam sub-districts, because the location faced directly to the Malacca Strait. The Rehabilitation and reconstruction activities have rebuilt the houses in the same spot area. More over the house models have not heeded the risk of tsunami. This study aims to identify the effect of model and material house toward the tsunami risk in Banda Aceh city. The research method used questionnaires that were distributed to 30 respondents from the expert. Data processing and analyzing used Structural Equation Model-Partial Least Square (Smarth-PLS) through standardized loading factor and composite reliability. The model shows that the variation in the value of the material and house model variables on tsunami disaster risk is moderate. Based on the results of the bootstrap calculation, all indicators have a significant effect on tsunami hazard except the type of non-permanent house structure. The results of the path coefficient show that a house with a stilt model has a significant effect on the level of tsunami disaster risk, while the house material on the walls of the house should use fabricated materials. To sum up, the construction of houses in tsunami risk areas should consider the model of houses on stilts with reinforced concrete materials. Stilt houses provide space for tsunami flows to avoid turbulence, and with a structure of house is resistance according building code.
