Abstract Disasters have just hit Palu, Sigi, and Donggala, resulting in the fall of so many victims, not only humans but also city and village physicals (residential buildings, facilities, and infrastructure). Several villages hit by the disaster were hamlet 3 Vou, Langaleso village, Dolo sub-district, Jono Oge village, Biromaru sub-district, and Sigi district. The village’s condition was damaged, but most of the buildings and plants were lost to the mud. Settlement neighborhoods that should be full of activity are nowhere to be seen, and people become apathetic. They just accept this situation and are always waiting for help. Huntara, a form of assistance provided by funders, temporarily occupy the settlers’ land because the condition of the land or land needs to be cleared for the rebuilding process. The provision of inclusive spaces is one of the efforts to mitigate disasters in residential areas, namely public spaces that can be used by all settlers. These spaces must be safe and provide comfort, easy to reach, and become part of the residential environment. Village arrangement is one way that can be done to minimize the impact of a disaster. Arrangement of buildings, facilities, and environmental infrastructure are necessary not to create chaos in development. Also, aspects of environmentally friendly residential (village) spatial patterns, structural systems, and building construction that meet the requirements (SNI), the application of local and humane wisdom are no less important to consider in the process of procuring inclusive spaces in settlements, structuring villages, especially after a disaster.

Abstract The inadequate consideration of the impact of building morphology on ventilation efficiency in many urban residential areas has resulted in a series of environmental problems that threaten human health. The purpose of this paper is to establish a prediction model between ventilation efficiency and building forms in residential areas. Firstly, the characteristics of vertical wind profile in residential areas are measured through unmanned aerial vehicle (UAV); secondly, the wind speed ratio (WSR) at different height levels under the impact of morphological index (floor area ratio, building density, average building height, enclosure degree, height fall and maximum building height) in the residential area is simulated by ENVI-met; finally, two kinds of prediction formulas are obtained: (1) the average ventilation efficiency at the pedestrian level and (2) the prediction formula of WSR at different heights. The results show that the wind speed (WS) in residential area below 35 m is about 0.6 m/s lower than that in park. The results of numerical simulation show that the mean WSR at the pedestrian level is negatively correlated with each index and the height fall morphological index has the greatest impact on the WSR at different heights. The research can provide a reference for the optimal planning and design of ventilation efficiency of residential buildings, especially those in static wind areas.

Sintang merupakan salah satu kota di Kalimantan Barat yang berada di pertemuan dua sungai, yaitu sungai Kapuas dan Sungai Melawi. Kelurahan Kapuas Kiri Hilir, Kelurahan Menyumbung Tengah dan Kelurahan Ulak Jaya merupakan kawasan permukiman padat yang sudah ada sejak lama di Sintang, dekat dengan pusat historis Kota Sintang yaitu Keraton Sintang dan tetap eksis sampai sekarang. Sedangkan kondisi dunia yang sedang mengalami pemanasan global mengakibatkan kawasan-kawasan yang berhubungan langsung dengan air rentan mengalami kenaikan permukaan air sungai (pasang air). Mengingat mahalnya harga nyawa manusia maka diperlukan penelitian pada pemanfaatan ruang sirkulasi dan ruang terbuka untuk mitigasi bencana berbasis bencana air ketiga kelurahan tersebut.Penelitian ini bertujuan mengidentifikasi dan mengilustrasikan model mitigasi bencana berbasis bencana air (hydrometeorological disaster), dilihat dari persepsi masyarakat dan pemanfaatan ruang sirkulasi dan ruang terbuka.Penelitian ini dilakukan menggunakan pola pikir induktif yaitu berpikir berlandaskan pandangan khusus ke umum. Teknik pengumpulan data, pengolahan data, dan analisis dilakukan dengan membandingkan metode kuantitatif dan kualitatif. Kuantitatif digunakan untuk mengukur persepsi masyarakat akan bencana berbasis bencana air. Sedangkan metode kualitatif mendeskripsikan dalam bentuk ilustrasi pemanfaatan ruang terbuka dan sirkulasi.Hasil penelitian persepsi masyarakat disimpulkan bahwa bencana yang sering terjadi adalah bencana kenaikan permukaan air (banjir/pasang). Masyarakat juga berpendapat walaupun mereka menghadapi kemarau, namun dampaknya tidak terlalu terasa karena mereka sudah mengantisipasi dengan menyediakan tempat penampungan air. Dan berdasarkan kondisi fisik lapangan, model mitigasi bencana berupa jalur sirkulasi berupa titian (papan kayu).Kata-kata Kunci: mitigasi, bencana, persepsi, ruang, sirkulasiTHE PERCEPTION OF RIVERBANK COMMUNITY ON UTILIZATION OF CIRCULATION AND OPEN SPACE AS DISASTER MITIGATION RESPONSE BASED ON WATER DISASTER IN SINTANGSintang is one of the cities in West Kalimantan which lies in the confluence of two rivers, i.e. Kapuas River and Melawi River. Kapuas Kiri Hilir Village, Menyumbung Tengah Village and Ulak Jaya Village have been densely populated residential areas in Sintang for a long time, located close to the historical centre of Sintang i.e. Sintang Palace and still exists today. While the condition of the world that is experiencing global warming has resulted in areas that are directly related to water susceptible to rising water levels (tidal water). Given the value of human life, research is needed on the use of the circulation space and open space for disaster mitigation based on water in the three villages.This study aims to identify and illustrate a model of water disaster-based mitigation (hydrometeorological disaster), seen from the public perception and utilization of circulation and open space.This research was conducted using an inductive mindset, which is thinking based from specific detail to general truth. Data collection techniques, data processing, and analysis were carried out by comparing quantitative and qualitative data. Quantitative was used to measure people's perceptions of disaster based on water-disaster. Whereas qualitative method described the illustration of open space and circulation.The results of the research on community perceptions concluded that disaster that often occurs is disaster of rising water levels (flood / tide). The community also believes that even though they face droughts, the impact is not too pronounced because they have anticipated it by providing water reservoirs. And based on the physical field condition, the suitable disaster mitigation model is circulation paths in the form of wooden board.Keywords: mitigation, disaster, percention, space, circulation REFERENCESHaifani, Akhmad Muktaf. 2008.

Disaster mitigation has been undertaken to reduce the impact of loss or damage caused by the earthquake. For disaster mitigation purpose, it is necessary to conduct a local geological assessment. The horizontal to vertical spectral ratio (HVSR) of microtremor analysis is very popular in the context of seismic micro-zonation. Microtremor method is cheap, data acquisition is easy, and does not cause noise, so suitable for use in residential areas. This research aims to determine the distribution of the natural frequency value, the amplification factor value, and the soil vulnerability index value. This study was conducted geographically between 7°26'17.45" – 7°26'53.16" S and 111°47'14.76" – 111°48'7.06" E. Data processing using HVSR analysis method on Easy HVSR software. The results showed that the natural frequency (<em>f<sub>o</sub></em>) values range 0,95 Hz to 8,3 Hz and the amplification factor values range 2,05 to 8,67. From the result data of the natural frequency and the amplification factor, the soil vulnerability index can be calculated. The vulnerability index (Kg) value ranges from 1,09 to 68,33. The northeast side of the study area is indicated as a weak zone where have high potential to damage when the earthquake occurred.

The proliferation of residential building energy consumption and CO2 emissions has led many countries to develop buildings under the green rating systems umbrella. Many such buildings, however, fail to meet their designed energy performance, which is possibly attributable to occupant behaviour and unforeseen building usages. The research problem lies in the fact that occupant environmental behaviour is a complex socio-cultural-technical issue that needs to be addressed to achieve the desired energy savings. This study is novel as it investigates complex interrelationships between many observed and unobserved variables using data from four LEED-certified multi-residential buildings in the United Arab Emirates. Structural Equation Modelling was used to analyse the impact of three unobserved/latent variables: occupant environmental Attitude, Knowledge and Behaviour (AKB) with respect to occupant energy consumption, based on measured/observed variables. Although our Goodness-of-Fit values indicated that we achieved a good model fit, the interrelationship between Knowledge and Behaviour (p = 0.557) and between Attitude and Behaviour (p = 0.931) was insignificant, as the p-values > 0.05. The key study outcomes were: (i) providing information alone could not motivate people towards environmentally friendly behaviour; (ii) even changes in their attitude, belief and lifestyle were not significantly related to their behaviour, as the interrelationships among occupant environmental AKB were not significant; and (iii) knowledge and attitude change should be combined with other motivational factors to trigger environmentally friendly actions and influence behaviour.

Since its commissioning in 2004, the UC San Diego Large High-Performance Outdoor Shake Table (LHPOST) has enabled the seismic testing of large structural, geostructural and soil-foundation-structural systems, with its ability to accurately reproduce far- and near-field ground motions. Thirty-four (34) landmark projects were conducted on the LHPOST as a national shared-use equipment facility part of the National Science Foundation (NSF) Network for Earthquake Engineering Simulation (NEES) and currently Natural Hazards Engineering Research Infrastructure (NHERI) programs, and an ISO/IEC Standard 17025:2005 accredited facility. The tallest structures ever tested on a shake table were conducted on the LHPOST, free from height restrictions. Experiments using the LHPOST generate essential knowledge that has greatly advanced seismic design practice and response predictive capabilities for structural, geostructural, and non-structural systems, leading to improved earthquake safety in the community overall. Indeed, the ability to test full-size structures has made it possible to physically validate the seismic performance of various systems that previously could only be studied at reduced scale or with computer models. However, the LHPOST's limitation of 1-DOF (uni-directional) input motion prevented the investigation of important aspects of the seismic response of 3-D structural systems. The LHPOST was originally conceived as a six degrees-of-freedom (6-DOF) shake table but built as a single degree-of-freedom (1-DOF) system due to budget limitations. The LHPOST is currently being upgraded to 6-DOF capabilities. The 6-DOF upgraded LHPOST (LHPOST6) will create a unique, large-scale, high-performance, experimental research facility that will enable research for the advancement of the science, technology, and practice in earthquake engineering. Testing of infrastructure at large scale under realistic multi-DOF seismic excitation is essential to fully understand the seismic response behavior of civil infrastructure systems. The upgraded 6-DOF capabilities will enable the development, calibration, and validation of predictive high-fidelity mathematical/computational models, and verifying effective methods for earthquake disaster mitigation and prevention. Research conducted using the LHPOST6 will improve design codes and construction standards and develop accurate decision-making tools necessary to build and maintain sustainable and disaster-resilient communities. Moreover, it will support the advancement of new and innovative materials, manufacturing methods, detailing, earthquake protective systems, seismic retrofit methods, and construction methods. This paper will provide a brief overview of the 1-DOF LHPOST and the impact of some past landmark projects. It will also describe the upgrade to 6-DOF and the new seismic research and testing that the LHPOST6 facility will enable.

&lt;p&gt;Spring floods have generated colossal damages to residential areas in the Province of Quebec, Canada, in 2017 and 2019. Government authorities need accurate modelling of the impact of theoretical floods in order to prioritize pre-disaster mitigation projects to reduce vulnerability. They also need accurate modelling of forecasted floods in order to direct emergency responses.&amp;#160;&lt;/p&gt;&lt;p&gt;We present a governmental-academic collaboration that aims at modelling flood impact for both theoretical and forecasted flooding events over all populated river reaches of meridional Quebec. The project, funded by the minist&amp;#232;re de la S&amp;#233;curit&amp;#233; publique du Qu&amp;#233;bec (Quebec ministry in charge of public security), consists in developing a diagnostic tool and methods to assess the risk and impacts of flooding. Tools under development are intended to be used primarily by policy makers.&amp;#160;&lt;/p&gt;&lt;p&gt;The project relies on water level data based on the hydrological regimes of nearly 25,000 km of rivers, on high-precision digital terrain models, and on a detailed database of building footprints and characterizations. It also relies on 24h and 48h forecasts of maximum flow for the subject rivers. The developed tools integrate large data sets and heterogeneous data sources and produce insightful metrics on the physical extent and costs of floods and on their impact on the population. The software also provides precise information about each building affected by rising water, including an estimated cost of the damages and impact on inhabitants.&amp;#160;&amp;#160;&lt;/p&gt;

Urbanization as a socio-economic process manifested in the concentration of the population in modern big cities contributes to the development of high-rise building construction. With the development of education and culture, changing leisure habits, city residents put forward new architectural and functional requirements to the living environment and urban infrastructure. This calls for the creation of new types and forms of residential buildings, the structure of the city and transport networks. In addition, the need to develop high-rise building construction is justified by the growing demand for residential, public and administrative buildings and the lack of free space.The paper analyzes the development of high-rise building construction in urban areas. The problem of the impact of high-rise building construction in big cities on the living environment is considered. Using analytical methods, causes and sources of pollution, such as transport and engineering infrastructure have been identified. In some urban areas, there are zones with modified thermal conditions and air exchange resulting in the formation of the “urban heat island”The qualitative and quantitative characteristics of variations in temperature and wind speed with respect to the height of the building have been calculated, using the example of the Evolution Tower of the Moscow International Business Center (“Moscow City”). Calculation and comparative analysis for the cities of Moscow, Khanty-Mansiysk and Vladivostok has made it possible to assess the variation in temperature and wind speed and their impact on the living environment under different climatic conditions.
