Perception of Visual Impairment Towards the Aesthetic of Architectural Elements
Get PDFPhenomenology in architecture is associated with perception between the subject and the space, which one of the studies includes multisensory experience. In general, contemporary architecture accentuates the visual experience, among other sensory modalities. Therefore, it is necessary to conduct research about the exploration of multisensory perception in architectural design. This study aims to explore how sensory activities or blind and visual impaired experience the spatial and the elements of architecture. This study is started by examining a brief literature review and then conducts qualitative research (in-depth interview and participant observation) to explore sensory experience and perception of blind people. The result finds from the five elements, walls and windows are the most influential elements for blind people. The existence of a wall has the potential to be a wayfinding of haptic system and has an echo effect. While the aperture opening element influences the illumination of light as well as indicators of outside space limits. The research outcome shows that people with visual impairment also acknowledge and they recognize these principles of design. They recognize contrast of temperature through the opening element, rhythm of texture through the wall, surface balance through the furniture, and hierarchy of noise through the window

Improvement Strategy for KOTAKU program in Slum Settlements Area in Sidoarjo
Get PDFKOTAKU (City Without Slums) program has been implemented in numerous areas identified as slums settlements, including in Sidoarjo, a city adjacent to Surabaya that has given many services in housing provision including for people who commute from Surabaya city. One of the efforts that must be done to handle the slums is to prevent and improve the quality of life and environment in a slum area to develop sustainable settlements to reach the objectives of Sustainable development (SDGs). One of the cases in this program happened in Tambak Cemandi, Sidoarjo where the slums area consists of 9.75 hectares widespread. The settlement area is located in the coastal area where it experienced a decrease in environmental quality due to a lack of public awareness in maintaining the cleanliness of the environment, most people dispose of garbage and defecation in rivers or ponds, and river conditions are filled with garbage, and not yet provided adequate infrastructure facilities. The article aims to formulate a strategy for improving the quality of slums in Tambak Cemandi, Sidoarjo. The first stage in this research is identifying factors that influence the quality improvement of slum settlements in the case study area using the content analysis method, continued by formulating strategies related to the influenced factors through a qualitative descriptive analysis method. The results showed in this article are strategies considering the influenced factors that are community behaviors, community participation, waste management facilities, sanitation infrastructure provision, road conditions, and population income
Modelling and Optimization of the Compressive Strength of High Volume Fly Ash ECC with Low Modulus PVA Fiber Using Response Surface Methodology (RSM)
Get PDFEngineered cementitious composite (ECC) also known as bendable concrete is popular for its high ductility behavior under tensile load. However, to achieve this amazing characteristic, the compressive strength is usually compromised due to the high volume fly ash (HVFA) effect of reducing the composite’s toughness. This research is aimed at developing a response surface model and optimization of the two major ingredients (fly ash and PVA fiber) with the view to developing a composite with the desirable compressive strength for structural application. Results indicated that although the FA affects the compressive strength development negatively, the presence of PVA fiber especially at 1 to 1.5% volume fraction enhances the compressive strength. A quadratic response surface model was developed and was analyzed using analysis of variance (ANOVA) and found to have a R2 value of 96.82%. The model validation showed a very good agreement between the predicted and the experimental results with less tha 5% error margin
The Other Sensory Approach on Exploring Urban Heritage Landscape. Case Study: Chinese Quarter of Semarang
Get PDFA new interpretation is needed to give meaning to conservation in the urban development framework and to support a sustainable cultural environment. Based on Québec Declaration (2008) and Burra Charter (2013), intangible dimensions became matter to give a richer and deeper meaning to the cultural heritage area. A shift has been seen in urban theories arguing for attention to the multi-sensory approach. This concept becomes matters as the raising critique towards the domination of visual perception in the built environment's design. The domination of audio-vision starting to reach out by the practitioners and scholars, unlike the other senses such as smell, tended to overlook and misconception. This paper outlines a pilot study's findings addressing holistic person-sensory experience in exploring the role of odor in shaping the cultural heritage area in Pecinan nowadays. It will discuss various scents detected, personal perception, and the link between odor and Pecinan's character. All this data was collected using a smells walk, questionnaire survey, and interview. This research aims to explore the potential interface in preservation conflict between the character of existing historic town and change as smellscape is part of the intangible element and part of triangle components of a sense of place in supporting successful urban place
Effect Of The Application Of Different Cooking Periods On The Physicochemical Properties And Microbial Safety Of Hot Pepper Sauce
Get PDFHot pepper sauce is a frequently used product in most Ghanaian homes, schools, and
restaurants, which occasionally serves as condiments. The cooking period during the
production process of hot pepper sauce results in physicochemical changes, which
affect the quality and safety of the sauce. The study seeks to determine the effect of the
application of different cooking times on the physicochemical properties and microbial safety of hot pepper sauce. The cooking periods were 10 minutes, 20 minutes,
30 minutes, and 1 hour for samples A, B, C, and D. Standard physicochemical and
microbiological techniques were employed in the various analysis. Sample D (1 hour
cooked) recorded the least moisture and ash content, insoluble acid ash, and a statistically significant acid value (
The Effects of Mobile Payment Dimensions toward Continuance Intention in Surabaya
Get PDFThe 4.0 industrial revolution allows people to make payments using mobile devices which is called mobile payment. Mobile payment users in Indonesia have enlarged a significant improvement in the last few years. However, the use of mobile payment in Indonesia has not dominated yet. Most of the payments that they use are ATM Transfers, debit cards, and internet banking. These indicate the lack of continuance intention in using a mobile payment. The aim of this study is to examine the effects of mobile payments dimension (mobility, customization, security, reputation), service quality toward continuance intention through trust, and also the effects of trust toward continuance intention through perceived risk. The data used in this study are obtained through a research questionnaire. Respondents in this study were 170 Go-Pay and OVO users domiciled in Surabaya who made transactions with Go-Pay and OVO at least twice in the last few months. The sampling method of this study was non-probability sampling. This study uses a quantitative approach with the Structural Equation Modeling (SEM) method for statistical test. SEM analysis was carried out using the Analysis of Moment Structures (AMOS). The results of this study indicate that mobility and security have a significant positive effect on trust. On the other hand customization, reputation, and service quality do not affect trust. Trust has a significant positive effect on continuance intention and perceived risk. Meanwhile, the perceived risk made a significant negative effect on continuance intention
Space Transformation Due to Conflict: Changes from Agricultural to Industrial Space in Manyar District, Gresik Regency
Get PDFChanges in the spatial area showed the dynamics of political economy. There is a problem regarding power relations in reproducing space, which will trigger a conflict between interests. These land changes, especially those related to changes in the form of agricultural land use to non-agricultural, have resulted in the loss of income sources for farmers. This paper focuses on the transformation of agricultural land into a non-agricultural one caused by conflict between several elements, including the local government, private businessmen, and the community, especially fishpond farmers who experience marginalization of agricultural land due to industrial development in Gresik Regency. The research is conducted using a qualitative approach with a descriptive type to support more in-depth research in analyzing urban spatial planning issues in the perspective of seeking spatial politics in Gresik district. The current reality is that the government tends to be more aligned with capital owners, which implies that spatial planning is manifested by profit-oriented development, high economic growth, and accumulation. The government mostly ignores ecological and social dimensions, which it considers non-linear with economic investment
Studies of the effect of melt spinning on the electrochemical properties of the AB2 Laves phase alloys
Get PDFA comparative study of the effect of melt spinning on the electrochemical properties of the C14 and C15 AB2 alloys has been performed. The wheel speeds of 630, 2100, and 4100 cm/s were applied during the rapid solidification of both alloys. The structural analysis of the formed phases was performed by X-ray powder diffraction (XRD), while their microstructural morphology was studied by scanning electron microscopy (SEM). In both alloys a tremendous grain refinement due to the melt spinning process was observed: In addition, melt spinning also significantly contributed to the morphological variation of the microstructural changes in C14 alloys which showed changes from the equiaxed grain at lower speed to the small dendrites at higher speed. In contrast to the C14 alloys, the morphological variation was not observed for the C15 alloys. Furthermore, for both C14 and C15 alloys melt-spun at 2100 cm/s the maximum capacities of 435 and 414 mAh/g were achieved, respectively. As both alloys revealed the significant grain refinement due to the melt spinning, an increase in electrochemical capacity was achieved. However, the melt spinning parameters need to be further optimized to improve poor activation behavior of the rapidly solidified alloys
Numerical Study of Epoxy-Ramie Fiber Composite as a Type IV Ballistic Resistant Material
Get PDFThis paper studies the response of epoxy-ramie fiber composite as ballistic-resistant material using a finite element model. The simulation test was conducted by varying the number of layers and referred to NIJ 0101.06 Type IV as the boundary condition. The model used was a panel made from epoxy-ramie composite laminates with a certain thickness and a 7.62 mm bullet. NIJ states that ballistic material should withstand penetration, and the back-face signature (BFS) should not exceed 44 mm. The impact energy is not briefly mentioned in NIJ failure criteria. The properties of the composite and the bullet were obtained from scientific literature and previous study. The effect of the number of layers on impact response was evaluated by the penetration, deformation, BFS, and absorbed energy
