Authors: Yandikaputri D B , Isnaeni H , Nuraeny E , Kusuma N R 
Published: February 2021

Abstract
This manuscript aims to discover how people with colour-blindness see and explore open space. Proper understanding of their experience in exploring three-dimensional spaces in the creative industries should now be considered as an essential requirement, especially to create an inclusive city. This research investigated the spatial experience in public space of two respondents: one from the protanomaly and the other from the. From interviewees’ experience and field observation, the study shows that the existence of contrast and shadow is crucial to create a spatial experience for the colour-blinds by perceiving depth. The result shows how the colours used in the area are still inadequate to support their deficiency. However, they are still able to navigate themselves around the space with the help of contrast and shadows produced in the space. These findings conclude the need to improve awareness and education within the creative industries towards colour-blindness to design a space that can be fully experienced by colour-blinds.
Binary spatial negotiation by Street Hawkers
Authors: Bestari R , Fuad A H 
Published: February 2021

Abstract
Public space is a setting than a backdrop, where social interaction occurs as a dialog communication in a city. The city is entertained by the presence of the street hawkers, which show a connection between the primary and the supporter. This connection does not only link to serve daily needs but also the use of spatiality. Jakarta is a capital city with many functions, one of them is as the commercial area. This study aims to show the idea of space mechanism by analyzing the transformation of space into thirdspace that is portrayed on the street hawkers in the sidewalk next to the MRT station in Jakarta. This study reveals the existence of binary opposition as the presence-absence in the public space. It happened as the result of negotiation done by the street hawkers through some factors, such as visibility, mobility, and pedestrian flows. The presence of street hawkers will support the development of social life according to the aspects of the smart city.

Published: February 2021

Abstract
This study discusses the shifting function of places between First Place, Second Place, and Third Place in a coworking space and workplace by understanding the relationship between spatial designs and behaviors possibility by its nested affordances. In building smart cities, the aspects of workplaces must be considered. The study engaged with the implementation of the character’s perception into space, based on Gibson’s theory of nested affordances in interactions between perception and action. With affordances as interactive possibilities from particular objects or environments. This research employed a means-end hierarchy method to acknowledge the nested relationship that occurs in two study cases. The study is a literature study about nested spaces in a workspace using secondary data from articles, web, and social media. The study reveals that space or place from a particular feature does not always have the same nested feature and functions as space or place that it occupies, which creates nesting function of places from first place, second place, third place, and vice versa. Showing how smart workplaces accommodates various needs of the workers.
A speakeasy bar in an urban settlement as a heterotopia space
Authors: Atmanagara T S , Nuraeny E 
Published: February 2021

Abstract
Speakeasies or illegal drinking establishments were widespread during the Prohibition Era in the 1920s in the United States of America. Since the US government banned the consumption, manufacture, and distribution of alcohol, Speakeasies’ underground nature created a new environment for people to drink and socialize. There is no identification of these places, solely relying on word of mouth to gain their popularity. There are similarities between the concept of speakeasies and heterotopia—Michel Foucault described it as a placeless place or a world inside a world. The term heterotopia is often used to illustrate disturbance in the surrounding environment. Are there correlations between speakeasy and heterotopia? Is speakeasy a form of heterotopia? This paper examines the correlation of heterotopia and speakeasy bars, as well as the question of whether speakeasy is a form of a heterotopia place. To a further extent, the discussion on social constraints occurring from the existence of a speakeasy bar in a settlement complex will be investigated through six heterotopia principles coined by Foucault. Through interviews and data observations in Oj’s Tavern, Bandung, this paper offers a new discussion on urban settlement and its connection to the heterotopia, and what it implies to the surrounding environment.
Wayfinding system for the blinds in the museum

Published: February 2021

Abstract
This paper explains how wayfinding system helps museum visitor to understand the information given in a museum. Museum user itself have a varied background of visitors, including people with disability such as blind people. As a public space, museum generally provide certain information for their visitors. Such information can be understood by visitors in different ways, therefore, visitors tend to move independently to understand the information given in the museum. To accommodate the needs of all visitors, adjustments are needed in the museum so that the museum can be accessed by all visitors. In this case, a wayfinding system appears to direct museum visitors when they are exploring the museum. The purpose of the wayfinding system itself does not only provide direction for a person to move, but also to understand the environment in which they are in. In general, the wayfinding system is presented visually, but for those who have visual disability it requires the use of other sensory to understand the wayfinding system. Therefore, an adjusted wayfinding system in the museum must be present optimally so that it can be accessed by all visitors including those with visual disability.

Published: February 2021

Abstract
Cement, sand, coarse aggregate and water are the materials to make a concrete mixture. The waste paper has been dumped as waste and causes environmental pollution behind the mill or landfill. The industry paper wastage for every year is increasing gradually. More spaces are being needed for landfills, uses energy loss of natural resources and increase of expenditure and various types of pollutions. Utilizing waste paper as an addition in concrete production will reduce environmental pollutions. This research is conducted to investigate the effect of shredded waste paper using copier and cardboard waste paper as additions to the compressive and flexural strengths and water absorption of hardened concrete. All specimens are subjected to water curing at 7 and 28 days. The results of compressive and flexural strengths increase at 5% and 10% additions of shredded copier and cardboard waste paper at 7 and 28 days of water curing. The finding shows that concrete containing 10% addition of shredded copier and cardboard waste paper exhibit the highest compressive and flexural strengths. For concrete water absorption, the higher water absorption is caused by the higher addition of shredded copier and cardboard waste paper. Furthermore, the results also show that shredded cardboard waste paper has higher strength and water absorption than shredded copier waste paper for all percentages of addition. This study indicates that shredded copier and cardboard waste paper can be used as additional materials in concrete production.

Authors: Rahman Saba , Jain A K , Bharti S D , Datta T K 
Published: February 2021

Abstract
The floating offshore wind turbine (FOWT) may have significant displacement and acceleration of the hub caused due to the wind-wave interaction. In this paper, a simplified cascaded analysis of the FOWT is presented in order to obtain a preliminary estimate of the responses of the hub using an iterative frequency domain technique. In order to carry out the analysis, the masses of the nacelle and rotor are lumped at the top of the hub, which is discretized into elements. At the base of the hub, two interface degrees of freedom consisting of a rotation and a translation is considered, which connect the two subsystems, namely, the hub and the floating body (spar). Both the wave and fluctuating components of the wind are considered as a random process represented by their power spectral density functions. The two subsystems are analyzed separately, and the interaction effect is incorporated through an iterative process. Using the above method of analysis, a FOWT having a 90m tall tower is analyzed under two random sea states, namely, 12m-18s and 5m-10s. Two mean wind velocities, namely, 12m/s and 20m/s are taken at the reference height of 10m. The results of the study indicate that significant absolute peak displacement and acceleration at the top of the hub may take place, requiring due attention to the safety of the design of FOWT.

Published: February 2021

Abstract
This study investigated the seismic behaviour of the single-outrigger frame systems and proposed the optimum location of outrigger in tall buildings compared to conventional approaches. For this purpose, a pushover analysis was carried out on different forms of the single-outrigger braced high rise buildings to capture the seismic response. An innovative Stiffness Ratio Method (SRM) technique has been utilised for small-scale 3-D modeling using Finite Element Modeling (FEM) in Abaqus/CAE software commercial program. The performance of single-outrigger systems under uniform loading was measured through lateral displacement and drift. The results confirm that by changing an outrigger’s position throughout the height of the building, the strength and stiffness will experience significant changes. Placing an outrigger at the top level of the building termed Cap model led to a reduction in lateral drift by 72 percent, while it reached 84 percent, where it placed at 0.4 height of the building hereinafter called Optimal model. Overall, the results showed that the optimal form of the single-outrigger systems’ efficiency is 17 percent higher than the conventional model (Cap model) in the reduction of the top displacement of the building under lateral loads.

Published: February 2021

Abstract
Seismic effect to the tunnel form building (TFB) will vary depending on the location of the epicentre, magnitude and frequency of the seismic event. This effect can be mitigated by implementing a seismic analysis using the Ruaumoko 2D programme. The seismic analysis was conducted to examine the safety level of the TFB when it was subjected to 10 previous seismic events. The analysis emphasized the in-plane direction of lateral cyclic loading. The 10 selected seismic excitations were Pacoima Dam, El Centro North-South and East-West, Mexico City, Ranau, Lahad Datu, Kunak, Batu Niah, Manjung and Bukit Tinggi. The analysis results of tunnel form building (TFB) in terms of spectral displacements, earthquake excitations, pseudo-spectral acceleration and deformed shape of single unit tunnel form building obtained in this study. Based on these analyses, tunnel form building (TFB) can only withstand low seismic loading with far-field earthquakes. When subjected to a seismic load greater than 5 Richter Scale and near field excitation, tunnel form building will not safe to be occupied.

Published: February 2021

Abstract
The rapid development in the construction of infrastructure on the hilly terrain has led to excavation of large bodies of rock mass to form cut slopes, resulting in the deformation and reduction in the stability of the rock material. As the slopes were cut more than 10 years ago, it is worried that there should be strength deterioration of the rock slope that could affect the stability of the slope. A study should be carried out to evaluate the recent condition of the slope in terms of its stability and safety after a long period of the exposure. A field study was conducted to collect the discontinuity data and laboratory test for the purpose of stability analysis using the existing stability analysis scheme of Rock Mass Rating (RMR) and Slope Mass Rating (SMR). The study was taken place at an exposed cut slope of a highway in Sri Jaya, Pahang. The objective of this study is to determine and evaluate the stability of the rock cut slope. A classification of the discontinuity parameters such as the strength, Rock Quality Designation (RQD), spacing, aperture, infilling, persistence, weathering, and groundwater have been used to determine the rock mass condition. The classification also need laboratory test for the point load strength (PLT) parameter. The RMR classification showed the rock to be very good condition, while the SMR showed the slope to be completely stable to stable. This study provide a good database in assessing the rock slope condition from time to time for the slope authority management.

Published: February 2021

Abstract
Over the years, rock slope will undergo the natural phenomenon of weathering, leading to the weakening of strength and physical properties of the slope material. In Malaysia, one of the causes of the weathering of rock is due to the presence of water, which can form groundwater table in the subsurface of rock slopes. The weathering of rock material in slopes can have significant effect on the stability. In Sri Jaya, Pahang, a large body of rock is exposed in cut slope, where different weathering grade was observed on the surface. The study aims to investigate the groundwater table under the rock slope surface and determine the extent of weathering of the rock slope. For that purpose, the electrical resistivity imaging (ERI) was chosen as a geophysical method to map the subsurface condition of the slope. Resistivity values from the survey were interpreted based on established work that correlates weathering condition of rock material with resistivity value. Different zones of weathering grade and groundwater were determined based from the profile.
Multi-Parameter Neural Network for Altimeter Tropical Cyclone Wind Speed Estimation
Authors: Sharoni S , Md Reba M N 
Published: February 2021

Abstract
The ability of satellite altimeter to estimate wind speed in tropical cyclone condition has been investigated. In the extreme condition with higher spatio-temporal variation, the ocean-atmosphere interaction is very complex and makes the existing algorithm become an ill-posed solution. In such condition, the developed algorithm from single frequency backscatter and significant waves height were insufficient. Besides, wind speed estimates become saturated at high regimes and the reflected backscatter was contaminated by rain. Therefore, other simultaneously observed parameters are needed to comprehensively account for this condition and is expected to improve the accuracy of wind speed retrieval. Aside from altimeter instrument, the microwave radiometer onboard Jason-2 concurrently records the brightness temperature and the rain information. To accommodate related multiple parameters for wind speed derivation, the neural network approach is proposed. Its unique advantage is relationship among multi-parameters can be easily established without prior knowledge on their physical attributes. Therefore, this study intended to determine the multi-parameter neural network (MPNN) model in estimating altimeter wind speed during the tropical cyclone condition. The results proved that the MPNN technique has potential in reducing the root mean square error by 30% in comparison between tropical cyclone wind speed estimate by the existing algorithm.

Abstract
Problematic soil such as marine clay causes structures or pavement to crack and collapse as marine clay possesses low bearing capacity. Therefore, ground improvement is usually conducted to improve the bearing capacity. Since the use of cement for strengthening weak soil is not environmental-friendly, the aim of this study is to improve the bearing capacity of marine clay using polyurethane (PU) columns. The properties of the marine clay collected from Batu Pahat determined were particle size distribution, Atterberg’s limits, specific gravity, and compressibility were determined. A series of small-scale physical modelling was conducted with a tank’s size of 500 mm x 500 mm x 200 mm. The 1:1 ratio of poly and isocyanate was injected into the cored hole for the column formation with the area improvement ratio was set as 12.6%. The loading process was conducted 1 day after column installation. Double tangent method from the stress-displacement curve was employed to determine the ultimate bearing capacity of the marine clay. The ultimate bearing capacity of the untreated marine clay was 50 kPa. In addition, the results showed that the ultimate bearing capacity of the marine clay increased with the length of the PU columns. A maximum improvement ratio of 220% was achieved for the end bearing PU columns. Comparing the improvement ratio with the published data showed that PU columns had a better performance than soil cement or deep mixing cement columns due to its lightweight and high strength. Therefore, the replacement of cement with PU is workable and sustainable in ground improvement method.
