Kuta Alam Sub District has many potential hazards, especially from the sea. The location of the area that is directly adjacent to the sea causes it to be very vulnerable to tsunami. Its topography is lowland less than 1 meter above the sea-level. Tsunami in 2004 had taken a great number of people lives in the area about 14.95 % of the total number of inhabitants which is 55,030 people that time. However, there is still no any evacuation building available in Kuta Alam to escape from Tsunami. We know tsunami which might be occurred anytime unpredictable. In order to save people’s lives, it is needed to conduct a study to find alternatives buildings to be used for evacuation and rescue in the area. The aim of this study to identify the locations and number of alternative buildings that are potential as the tsunami evacuation building in Kuta Alam Sub-district. The study used the survey system toward the buildings with qualitative and quantitative approaches. Data analyzing is conducted spatially through geographic information systems. Based on observation results toward evacuation building in Kuta Alam Sub-district, there are some buildings renovated in order to be functioned as tsunami evacuation buildings. The renovation should be done on roof, school, and ladder evacuation of the mosque that are selected as evacuation buildings. Until today, those buildings have not been renovated to be eligible as evacuation places. The result found that there are 45 public buildings that can be used for alternative evacuation buildings in Kuta Alam Sub-district. That can accommodate 94.06 % of the total number of people this time which is 49,011 people.
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.
Settlement in coastal areas is at risk of a tsunami disaster. In urban areas, the risk of disaster can be greater than the area behind it. This study aims to analyze the priority of tsunami disaster mitigation based on settlements criteria in urban areas. The data collection technique uses a questionnaire given to experts in the field of disaster mitigation. The research variables consisted of occupancy typology, settlement locations, settlement patterns and density, coastal environment, evacuation routes and evacuation sites. Processing and analyzing data using statistical product and service solution software. The results of the regression analysis obtained that the settlement model Y = 3,055 – 0,410 residential typology + 1,119 settlement locations -0,017 settlement patterns + 1,323 settlement density + 0,040 coastal environment + 0,853 evacuation routes + 0,875 evacuation places. A high correlation was obtained on the location criteria and settlement patterns. Based on the mean value, the criteria for vertical evacuation places have the highest value, so can be recommended as a priority for the tsunami mitigation plan in urban settlements.
Banda Aceh sebagai ibukota Provinsi Aceh mengalami kenaikan kepadatan penduduk setiap tahunnya. Ini menyebabkan meningkatnya pembangunan perumahan KPR mulai dari Kota Banda Aceh merambat ke daerah yang bersisian. Desa Miruk, Aceh Besar merupakan salah satu daerah dimana pengembang berfokus membangun rumah dengan sistem KPR. Sebagai wilayah rawan gempa, pembangunan perumahan harus sesuai dengan pedoman rumah tahan gempa. Dari penelitian terdahulu ditemukan ada pembangunan rumah sederhana dengan sistem KPR bersubsidi yang tidak sesuai dengan pedoman rumah sederhana tahan gempa. Oleh karena itu pada penelitian ini, peneliti tertarik untuk meneliti ketahanan gempa pembangunan rumah di kawasan Miruk yang dijual dengan sistem KPR komersial (non-subsidi). Observasi ditinjau dari lokasi, denah, pondasi, pekerjaan struktur dan kuda-kuda. Dari hasil penelitian diketahui dari segi lokasi, denah, pondasi dan kuda-kuda telah memenuhi ketentuan, akan tetapi pada pekerjaan struktur ada detil-detil yang tidak sesuai. Oleh karena itu dapat disimpulkan bahwa secara umum rumah KPR daerah Miruk termasuk rumah tahan gempa akan tetapi tidak optimal karena ada detil-detil dalam pekerjaan struktur yang tidak terpenuhi.
