ABSTRACT Bandar Lampung is an area in Indonesia which has a high level of Tsunami threat. It is due to the position of Bandar Lampung which is located relatively near the meeting point of Indo-Australian plate dan the Eurasian plate; both are plates are relatively active. Other causes are earthquake threat and the existence of Krakatoa which is potential to generate earthquakes which are followed by a Tsunami. The data analysis showed that the potential Tsunami hazard in the coastal city of Bandar Lampung is the predicted distance run up the marinade tsunami that reached a height of 20 meters above sea level. Potential hazards include four districts, i.e. Bumi Waras District, Panjang District, South Teluk Betung District, and East Teluk Betung District. The research method is Cell-Based modeling, the one using the tool model builder in Arc GIS with 1 meter raster grid analysis, which can show and explain in detail the attributes that exist in the region. From Quick Bird image that has of 0.6 meter resolution, the existing condition of the land use can be clearly seen. The results of the analysis showed the vulnerability of Tsunami in the city of Bandar Lampung. The results showed that Bumi Waras District has the highest vulnerability level at Bumi Waras Subdistrict with an area of 85.62 Ha. Panjang District has the highest level of vulnerability at Pidada Subdistrict with an area of 30.16 ha. South Teluk Betung District has the highest level of vulnerability at Pesawahan Subdistrict with an area of 0,02 Ha. East Teluk Betung District has the highest level of vulnerability at Kota Karang Subdistrict with an area of 32.11 Ha. Keywords: Tsunami disaster, Vulnerability and cell-based modeling

Facility of directions to the evacuation places in the city of Bengkulu is very minimal, so that people are very difficult to find an efficient route to the evacuation places. The problem is how to determine the evacuation route/gathering point. Indonesia is prone to earthquakes because logically, the Indonesian archipelago is at the confluence of three tectonic plates: the Eurasian plate, the Australian plate and the Pacific plate. In the event of an earthquake and tsunami disaster, if disaster preparedness is not prepared, it will cause damage to buildings, offices and can result in fatalities such as the events in Nangro Aceh Darussalam. Therefore, we need a system that can help overcome this disaster management. The system that can be made is the Information System for Determining Earthquake and Tsunami Evacuation Paths in the city of Bengkulu Using Android. By using Android, it will be easier for people to imitate an evacuation route or place during an earthquake and tsunami.

The Indonesian region has a high level of earthquake vulnerability when compared to other countries. This is because Indonesia's position is at the confluence of three large tectonic plates namely the Eurasian plate, the Indo-Australian plate, and the Pacific plate. The high level of earthquake susceptibility is evidenced by significant earthquake data from 2005 to 2009, which recorded 26 significant earthquakes over a period of 4.8 to 8.6 on the Richter scale. The earthquake also caused impacts including casualties, injuries, damage to houses and destruction of houses.The earthquake event grouping system is a system that functions to classify earthquake events based on two main parameters, namely earthquake strength parameters and earthquake impact parameters. The two parameters are grouped separately, so that the grouping process produces two kinds of grouping results. The stages of this system start from preprocessing data to eliminate noise, then take grouping parameters from the user in the form of the number of clusters, minimum error values, and the maximum iteration limit. Grouping is done using fuzzy c-means method. The grouping results are then displayed in table form and in the form of coordinates in Google Maps.The grouping of earthquake events has been tested by comparing the results of grouping systems with the results of manual grouping. Testing is done by inputting a number of different maximum iterations. Based on the test results it was found that the greater the maximum iteration value will affect the accuracy of grouping.

Abstract Earthquake is one of the most frequent disasters in Indonesia. This is due to the location of Indonesia which is located between 3 active plates, namely the Pacific Plate, the Indo-Australian Plate and the Eurasian Plate. While from 2018 to date the biggest and worst earthquake in the Lombok Earthquake that occurred with magnitude reached 7 on the Richter Scale and hammer earthquakes with magnitude 7.4 on the Richter Scale. One of the frequent failures caused by the earthquake is the soft store. Soft story mainly occurs in office buildings, hotels or apartments which generally have a lobby or area that is intentionally made without walls / dividers, either on the ground floor or the upper floors so that inter-floor fuss will be different. In designing and modeling structures, buildings are generally designed with open frame type port without walls. The height of the column can also cause a difference between different floors. This study will compare between the wallless portal model with a higher level at the bottom of the building, the middle of the building and the top of the building, where a high level with smaller stiffness has the potential to be soft (soft story). In this study using ETABS 9.7.2 program with spectrum response dynamic load based on the 2017 earthquake map. Results The structure period of the results of the analysis with the program in the crack cross section condition was obtained at 2.01 seconds. The shape mode for the three PPKBB, PKBT and PKBA building types has met the requirements where in shape 1 and 2 building models are translating towards the x or y axis while in shape 3 mode they are twisted. The required mass participation ratio value is reached at the 90% percentage reached at the 8th shape mode for the PKBB and PKBT buildings. While for PKBA it is reached in the 5th shape mode. Deviation values ​​for the three types of building PKBB, PKBT and PKBA are still within the permit limit. Keywords: earthquake, soft storey, spectrum response

Abstract The study aimed to identify the hazard level distribution in the slum areas in Palembang City. The research was a quantitative type with 382 families that live in the slums as the samples. The data were collected using proportional area random sampling and analyzed using the K-means Cluster test through SPSS 23. Spatial analysis through Arcgis was conducted to complete the understanding of the hazard distribution in the slum areas. The results showed that the hazard clusters formed by 64 areas could be categorized into three: low, medium, high. High level of hazards, reaching the one-third portion of the areas, dominated the slums in Palembang City. The cluster with a high hazard level was mostly in the city center, which was geographically located on the riverbanks, causing the areas to be vulnerable to flood, diseases, and crimes. The city center was known to offer high numbers of the job vacancy. People in the slums working in the city center were day laborers.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

An anaerobic inverse turbulent bed, in which the biogas only ensures fluidisation of floating carrier particles, was investigated for carbon removal kinetics and for biofilm growth and detachment. The range of operation of the reactor was kept within 5 and 30 kgCOD· m−3· d−1, with Hydraulic Retention Times between 0.28 and 1 day. The carbon removal efficiency remained between 70 and 85%. Biofilm size were rather low (between 5 and 30 μm) while biofilm density reached very high values (over 80 kgVS· m−3). The biofilm size and density varied with increasing carbon removal rates with opposite trends; as biofilm size increases, its density decreases. On the one hand, biomass activity within the reactor was kept at a high level, (between 0.23 and 0.75 kgTOC· kgVS· d−1, i.e. between 0.6 and 1.85 kgCOD·kgVS · d−1).This result indicates that high turbulence and shear may favour growth of thin, dense and active biofilms. It is thus an interesting tool for biomass control. On the other hand, volatile solid detachment increases quasi linearly with carbon removal rate and the total amount of solid in the reactor levels off at high OLR. This means that detachment could be a limit of the process at higher organic loading rates.

Climate justice requires sharing the burdens and benefits of climate change and its resolution equitably and fairly. It brings together justice between generations and justice within generations. The United Nations Sustainable Development Goals summit in September 2015, and the Conference of Parties to the Framework Convention on Climate Change in Paris in December 2015, brought climate justice center stage in global discussions. In the run up to Paris, Mary Robinson, former president of Ireland and the UN Secretary General’s Special Envoy for Climate Change, instituted the Climate Justice Dialogue. The editors of this volume, an economist and a philosopher, served on the High Level Advisory Committee of the Climate Justice Dialogue. They noted the overlap and mutual enforcement between the economic and philosophical discourses on climate justice. But they also noted the great need for these strands to come together to support the public and policy discourse. This volume is the result.

This research analyzed the online reputation of Marbella as a tourist destination and the profiles of the reviewers according to sociodemographic characteristics. A correlational, quantitative research technique was used in this study based on the manual extraction of more than 4000 reviews generated on TripAdvisor. The data used in this study were collected from the TripAdvisor website, taking, as a sample, tourists who had visited the city in the last three years. Ratings that did not provide full data on the variables were excluded. The findings show that Marbella is considered a luxury shopping destination. The preliminary conclusions allow us to generalize about the sociodemographic profile of its tourists. The findings of the study will provide valuable information for Marbella’s Destination Management Organization (DMO). On the one hand, this study highlights the importance of ranking the attractions of the city to create better communication strategies and enhance the appeal of those attractions that receive the best ratings, establishing the true vocation of Marbella as a tourist destination. On the other hand, it provides information on what tourists perceive to be negative elements, allowing the administration to create an improvement plan. The novelty of this research paper is that it delves into Marbella’s online reputation through an analysis of specific attractions’ ratings. Areas that require further attention in future research have been highlighted, along with specific advice on each attraction that contributes to the tourist offerings of the city.

In recent years, policymakers of urban agglomerations in various regions of the world have been striving to reduce environmental pollution from harmful exhaust and noise emissions. Restrictions on conventional vehicles entering the inner city are being introduced and the introduction of low-emission measures, including electric ones, is being promoted. This paper presents a method for scenario analysis applied to study the reduction of exhaust emissions by introducing electric vehicles in a selected city. The original scenario analyses relating to real problems faced by contemporary metropolitan areas are based on the VISUM tool (PTV Headquarters for Europe: PTV Planung Transport Verkehr AG, 76131 Karlsruhe, Germany). For the case study, the transport model of the city of Bielsko-Biala (Poland) was used to conduct experiments with different forms of participation of electric vehicles on the one hand and traffic restrictions for high emission vehicles on the other hand. Scenario analyses were conducted for various constraint options including inbound, outbound, and through traffic. Travel time for specific transport relations and the volume of harmful emissions were used as criteria for evaluating scenarios of limited accessibility to city zones for selected types of vehicles. The comparative analyses carried out showed that the introduction of electric vehicles in the inner city resulted in a significant reduction in the emission of harmful exhaust compounds and, consequently, in an increase in the area of clean air in the city. The case study and its results provide some valuable insights and may guide decision-makers in their actions to introduce both driving ban restrictions for high-emission vehicles and incentives for the use of electric vehicles for city residents.
