Pengaruh Waterfront Terhadap Kondisi Lingkungan Sosial Kelurahan Benua Melayu Laut

Waterfront is a concept to support the availability of open spaces in Pontianak City. Besides functioning ecologically, Waterfront can also function aesthetically and economically so that its existence affects the social environment. One of the most popular Waterfront locations for visitors is the Waterfront  in Benua Melayu Laut Ubran Village. The study aims to determine the effect of the Waterfront on the conditions of the social environment in Benua Melayu Laut Urban Village. The analysis used is the frequency distribution and composite index. The results showed that the effect of Waterfront on social environmental conditions was high with an index value of 3.01. This influence can be in the form of a positive or negative influence. Positive influences include increased public awareness of the social environment, increased sense of responsibility in maintaining environmental quality, a high sense of care among fellow citizens and increased cooperation in improving environmental quality and aesthetics. The magnitude of this positive influence can have implications for the comfort and safety of the social environment. Meanwhile, the negative effects that can occur are high conflicts and unfair competition which have an effect on the decline in the social security of the Waterfront Benua Melayu Laut

Assessment of recreation space along the Hudson river waterfront in Jersey City, NJ

For the past decade Jersey City, New Jersey has worked to redevelop its waterfront. The once highly industrialized waterfront is now the location of residential and commercial uses and more projects are slated for the future. Although many improvements to the physical and built environment occurred along the waterfront, many question whether enough emphasis was placed on outdoor recreation. Site assessments, field observations, and surveys of waterfront users in Jersey City, NJ were conducted to determine what uses are possible, and in the greatest demand on the waterfront. A total of (950) field observations were made of waterfront users. This information was supplemented with data from (35) structured interviews conducted with waterfront users. The results identify recreational opportunities, public perceptions, and waterfront use levels. Waterfront users participate primarily in non-water related activities. There is a high demand for, and participation in, active recreational activities on the waterfront. Waterfront sites offering an unobstructed view of New York City, convenient location, and a high level of safety were the most popular. Waterfront users expressed demand for more activities such as waterfront dining, and shopping. The results provide important baseline data that has value to waterfront planners when evaluating waterfront development proposals

Using NDN in improving energy efficiency of MANET

This paper seeks to extol the virtues of named data networking (NDN), as an alternative to host-centric networking (HCN), for its prominent features that can be taken advantage of to significantly reduce energy consumption demands in a mobile ad hoc network (MANET) implementation. Therefore, a NDN-based content routing mechanism was compared with two types of HCN routing protocol implementations in this study: OLSR and Batman-adv. The experimental results obtained from this research provide early evidence that NDN can increase the energy efficiency of MANETcompared to the use ofHCNprimarily TCP/IP on the network stack solution for MANET. Of particular note would be NDN-based content routing’s viability as a solution for energy consumption issues that plague wireless multi-hop ad hoc networks. Last but not least, this paper also provides the future research direction that could be undertaken on the subject

Preparation and characterisation of inexpensive porous kaolin hollow fibre as ceramic membrane supports for gas separation application

Low-cost, porous ceramic kaolin-based hollow fibre membrane support (HFMS) for gas separation application was developed via phase inversion technique. The ceramic suspensions with various ratios of kaolin to polyethersulfone (PESf) binder (5:1 to 9:1) were extruded and then sintered at 1200 to 1500 °C. The HFMSs were characterised by several analyses to investigate the effects of kaolin/PESf ratio and sintering temperature on the sample properties. The results showed that the kaolin/PES ratio and sintering temperature affected the considerable structure and physical properties of the kaolin membrane. It is observed that with increasing sintering temperature, the porosity and gas permeation of the HFMS decreased, while the bending strength and density of the HFMS increased. As a result, a porous HFMS with sufficient mechanical strength and high gas permeation characteristics is achievable if the appropriate kaolin/PESf ratio and sintering temperature are chosen

Measurement and analysis of water/oil multiphase flow using electrical capacitance tomography sensor

The paper investigates the capability of using a portable 16-segmented Electrical Capacitance Tomo-graphy (ECT) sensor and a new excitation technique to measure the concentration profile of water/oil multiphase flow. The concentration profile obtained from the capacitance measurements is capable of providing images of the water and oil flow in the pipeline. The visualization results deliver information regarding the flow regime and concentration distribution of the multiphase flow. The information is able to help in designing process equipment and verifying the existing computational modeling and simu-lation techniques

Sustainable urban development in practice:the SAVE concept

The need for sustainable development of the urban environment presents the research community with a number of challenges and opportunities. A considerable volume of research has been undertaken into the constituent parts of this complex problem and a number of tool kits and methodologies have been developed to enable and encourage the application of specific aspects of research in practice. However, there is limited evidence of the holistic integration of the body of knowledge arising from the research within real-life decision-making practices. In this paper we present an overview of the existing body of knowledge relating to sustainable development of the urban environment and propose a generic framework for its integration within current practices. This framework recognises the need to: understand social, economic, and environmental issues; understand the decision-making processes; provide a means of measurement, assessment, or valuation of the issues; provide analytical methods for the comparative assessment of complex data to enable an evaluation of strategies and design options and to communicate effectively throughout the process with a wide range of stakeholders. The components of a novel sustainability assessment, visualisation and enhancement (SAVE) framework, developed by the authors to ‘operationalise’ the body of knowledge are presented and justified. These include: decision-mapping methods to identify points of intervention; indicator identification and measurement approaches; appropriate mathematical and analytical tools and an interactive simulation and visualisation platform which integrates and communicates complex multivariate information to diverse stakeholder groups. We report on the application of the SAVE framework to a major urban development project and reflect on its current and potential impact on the development. Conclusions are also drawn about its general applicability

Evaluation of the performance of granular fertilizer boom sprayer through computational fluid-particles-dynamid CFD simulation and scaled-down model analysis

Malaysian Agricultural Research and Development Institute (MARDI) had bought two Japanese made granular fertilizer boom sprayers to test it on Malaysia’s Paddy field. In order to confirm the local feasibility of this fertilizer applicator, they had called UTHM researchers for proper experimental and numerical evaluations. A year of experimental assessments, the conclusion was supported with full range of numerical results and has a good agreement with MARDI’s findings. In this evaluation, ANSYS CFD was used for the fluid-particles-structure simulation while the statistical and image processing were made via MATLAB software. The simulation results were verified with the results from an in-house scaled-down model which was fabricated with the ratio of 2:15. The simulation was carried out by manipulating the angles of the boom sprayer collecting plates, ranging from 32o to 120o. The length of the collecting plate, the distance of the blow head, the sizes of the fertilizer and the air velocity of the blower were also varied in order to establish the correlations between the parameters. The ambient pressure was kept at 1 atm. Even though we managed to find 60o as the optimum collecting plate angle for most fertilizer sizes, there are two major factors that made it impossible to obtain good fertilizer distribution namely; the use of mixture of three different fertilizer (Nitrogen, Phosphorus and Potassium) sizes at once and the varying velocity profiles throughout the boom sprayer

Enhancing urban sustainability through novel visualisation

Sustainable decision making in Urban Design is a complex and non-linear process that requires the interaction of a wide variety of stakeholders. The engagement of a range of stakeholders throughout the decision making process presents challenges including the need to communicate the complex and interdependent facets of sustainability and the need to demonstrate the short and long term implications of alternative courses of action.This paper presents the results of an initial application of a prototype simulation and visualisation tool (S-City VT) that was developed to enable all stakeholders, regardless of background or experience, to understand, interact with and influence decisions made on the sustainability of urban design. S-City VT takes the unique approach of combining computer game technology with computer modelling to present stakeholders with an interactive virtual development. The paper uses the Dundee Central Waterfront Development Project as a case study to evaluate the potential for the application of the tool and explains how parallel research work on the implementation of a sustainability enhancement framework for the Central Waterfront Development has informed the choice of sustainability indictors and identified the key stakeholders in the decision making processes.The paper shows how stakeholders can be presented with the outputs from the model using a 3D visualisation of the development and thus enables judgements to be made on the relative sustainability of aspects of the development. The visualisation tool employs a number of different methods of displaying the sustainability results to the stakeholders. These methods can show data in varying levels of complexity, depending on the expertise of the stakeholder, empowering all stakeholders by illustrating possible interactions between indicator values and sustainability and by showing how different stakeholder perceptions of the importance of the indicators can influence the sustainability assessment.Initial tests on the effectiveness of the different visualisation methods in displaying the model output to communicate the sustainability of the Development are described. The results of the tests and presented and discussed and conclusions are drawn on the further development and application of the tool to model and visualise through time the possible results of decisions made at different stages of the project

Stinking Foreshore to Tree Lined Avenue: Investigating the Riverine Lives Impacted by the Construction of the Thames Embankments in Victorian London

Victorian London saw dramatic physical changes along the river Thames. Large enclosed Docks and Thames Embankments were constructed as the city struggled to cope with its ballooning population and prospering shipping industry. Whilst the Thames Embankments have been hailed as engineering triumphs, the fate of those whose livelihood relied on access to the river in central London (such as wharf workers, barge, ferry and lighter men, and others) is unknown. In order to investigate the impact of the Embankment, a methodology has been developed which enables characterisation of a large swathe of urban riverside throughout the mid- to late 19th century, whilst also ensuring that the stories of individuals and communities are not lost. The approach combines and adapts established methodologies, such as Historic Landscape/Seascape Characterisation and Maritime Cultural Landscapes, to understand the nature and changes in the urban riverside landscape. This methodology forms the background for detailed research on smaller sites, such as a single street, housing block, or industrial site, in order to create ‘Ethnographies of Place’. These small-scale ‘Ethnographies’ have the potential to tell stories about how the social and economic circumstances of individuals and communities changed as a result of the landscape changes associated with the Embankment construction. This paper presents the initial work to establish the methodology and preliminary conclusions based on key sources
