EVALUATION OF SOMBO FLATS ASSOCIATED WITH ENVIRONMENTAL DEVELOPMENT
Full text linkHomes as basic human needs have an important role in the growth of the inhabitants. In fact, many people do not have access to adequate housing. Surabaya as one of the big cities in Indonesia also has problems in providing decent dwelling for the residents of the city. Flats are built as one of the solutions for settlement problems in Surabaya. One of the settlement problems that are answered with the provision of flats is the Sombo flats. The Sombo flats were built in stages and has been operating since 1992. When viewed today, the existing condition of Sombo flat has undergone many functional shifts and quality degradation. In addition to the growing population, there are internal problems of the inhabitants such as low ecological cultural awareness. This research is a form of evaluation of the function and quality of Sombo flat with descriptive-qualitative method. From the evaluation and analysis conducted, it currently needs rejuvenation with ecological and sustainable community and environmental participation approach
OPTIMIZING THE ECOLOGICAL FUNCTIONS OF PUBLIC GREEN SPACE IN KLOJEN SUB-DISTRICT, MALANG CITY
Full text linkMalang city has a high level of construction development causing many conversions of green open space into developed areas. One region that has a lot of green open space conversion into developed areas is Klojen Sub-Distric. The converted area is used to built a shopping center, residential areas and regional government office. This causes some environmental degradation, including increasing of air temperature in Malang city and reduced ability of green open space to produce oxygen. The purpose of this research is to optimize the ecological functions of green open space in Klojen Malang. The ecological functions that will be discussed are green open space as oxygen producer and as air temperature controller.The approach used in this research is positivistic, as the basis of experimental studies which use quantitative methods to verify the research hypothesis. The research type is a combination of descriptive and quantitative using techniques such as mapping analysis, characteristics of plant components and softscape analysis, oxygen demand analysis, biomass analysis, inter polation analysis, the average daily air temperature analysis, scoring analysis and descriptive analysis of green open space optimization.The results obtained in this research are to optimize the ecological function of green open space by adding 1216 trees, to increase frequency value and density. Criteria are suggested for the additional trees, to be suited to the characteristics of each open green space. Based on the optimization concept, the oxygen demand can be reduced by 42.3%. Moreover, it can also reduce the air temperature of public green open space to a minimun ideal urban air temperature, which is 27,5 oC
THE EFFECT OF ROOM MATERIAL TO OVER-COME THE NOISE DUE TO MOTORCYCLE WORKSHOP ACTIVITY AT HOME BASED-ENTERPRISED NEARBY ROADWAY
Full text linkHome based-enterprised is currently booming in Indonesia. Home based-enterprised is a right choice for people who want to have a business that integrates with their home. From some of business which has the highest noise level is a home with motorcycle repair business. Because the source of noise in the workshop is the engine and other supporting machinery. Home business is generally situated near from roadway and has acoustic problems aspect. Motorcycle repair service located near from roadway receives noise from inside and from outside (roadway).The sound sources distribute noise through building elements, such as walls, floors and ceilings. Thus it needs to be researched the elements of room that potentially reducing noise, especially noise that transmits through the airborne.To determine the noise level and effect that transmit through the airborne, the study using physical data collection with field studies. While the method using the experi-mental methods with simulation methods where in its implementation procedures use some software like Ms. Excel and Ecotect to analyze the Sound Pressure Level (SPL) and Transmission Loss.The result showed that the characteristic of the materials (Transmission Loss & Leq) influence on noise through the airborne. Thus it is obtained the right solution to overcome and reduce the noise at shophouse through the selection of appropriate material that can reduce airborne noise. The appropriate organic and anorganic material selection are expected to be the solution of the existing problems. The ex-periment results show that all of the material (organic & anorganic) can reach the goal, but the best result is combination of both material, the organic material and anorganic material
APPLICATION OF ACOUSTIC MATERIAL FOR FACADE TO REDUCE NOISE IMPACT IN BUILDING LOCATED NEAR FROM RAIL
Full text linkFacade is a main component to reduce noise impact from the outdoor area. A room is considered as a cozy place, if the condition is set with Noise Criteria (NC) of 30-35 dB (A). The standards of room comfort should be applied in each area, one of them is Hotel Sahid Surabaya building located close to the railway. Acoustic insulation is certainly necessary and applied in some elements of the facade building. A way to improve the comfort in the building is with selection of materials that will be applied to the interior wall. In addition there is reference such as the use of diffuser on the exterior wall. This research is about the increasing of acoustic insulation on the hotel room facade with case study of Sahid Hotel Surabaya by measuring level of acoustic insulation on the inner wall and outer wall in one of the hotel room. The research study is focused on the noise impacts caused by airborne sound. This research use quasi experiment. The research objectives of this paper are to inform the wall insulation material in buildings and as a reference of the use exterior wall diffuser which are suitable for outdoor area. According to the earlier research, the use of a diffuser on the exterior facade is able to reduce noise until 30-35%. As for the results of an alternative design, the use of insulation material in the form of fibers with fiber type-800 on the inner wall has produced good insulation levels. This study is expected as a reference for designing especially buildings located close to the rail to support the acoustic comfort
INTEGRATED CONFIGURATION OF FOLDING ROOF-BIPV AND ITS OPTIMATION AT OFFICE BUILDING IN SURABAYA
Full text linkBIPV (Building Integrated Photovoltaics) refers to the application of PV (photo-voltaic) in which the system as well as having the function of producing electricity, also takes the role of building form and element. Empirical facts show that PV in BIPV system is integrated as add-on element only. They didn’t take the role as form giver yet. Electricity output generized by BIPV depends on the amount of solar radiation received by PV panel. There are some factors affect the amount of radiation received. Two of them are tilt and orientation angle of PV panel, and total area prepared for PV panel installment.This research try to rise electricity output by collaborating those two factors with orientation and multiplicity principle in folding concept. Folding element can be arranged based on optimum tilt and orientation angle to reach maximum radiation supply. Also, the collaboration results in bigger surface area to receive higher solar irradiance. Experiment with simulation as it tools will be used as research method to get the optimal configuration of Folding Roof-BIPV
A CASE OF URBAN MIMICRY: CITRA RAYA, THE SINGAPORE OF SURABAYA
Full text linkUnder the forces of globalization, there is considerable pressure for cities to enhance their attractiveness in numerous ways in order to attract capital. Surabaya, Indonesia’s second largest city, promotes a strategy to match the aesthetic criteria associated with imagined global metropolises. Singapore has been extremely influential in inspiring other cities in the South East Asian region and a dream to be another Singapore certainly appears in Surabaya. Imitating Singapore’s gleaming towers and exotic waterfront, Surabaya has sought to eliminate backward scenes including more traditional settlement forms. Interestingly, this trend to create an image of Singapore is not only supported by the business community but by the Surabaya’s government as well. This paper explores how the image of Singapore has influenced the shape of Surabaya in both systematic and practical ways, particularly addressing to what extent this obsession with Singapore has affected Surabaya images and identities
ILLEGAL URBAN ENTREPRENEURSHIP? THE CASE OF STREET VENDORS IN LAGOS, NIGERIA
Full text linkThis paper considers the vulnerabilities experienced in making a living as a street trader in Lagos, Nigeria. Using the Tejuosho - Yaba - Ojuelegba - Barracks quadrant as a case study, the paper investigates the socio-economic profile of street traders, their basic survival strategies and goes further to examine the interface between street vendors and related urban stakeholders. Relying on both qualitative (informed participant interviews) and quantitative (survey by purposive sampling) data analysis, the study revealed that most of the respondents were aged between 16 and 35 years old and operated subsistence enterprises which were begun due to unemployment and the high cost of the renting stalls at the nearby Yaba market. The major challenge experienced was the institutionalized harassment by KAI officials, which aided extortion by other local stakeholders. The paper concludes by highlighting the potentials of the informal economic sector and the strategic role it plays in the emerging African city form
GREEN URBAN WATERFRONT MANAGEMENT CASE OF SOLO, INDONESIA
Full text linkSolo is a city located in Central Java, Indonesia with 501.650 inhabitants in 2011. It hosted in 2010 the Asia Pacific Ministerial Conference on Housing & Urban Development (APMCHUD) as big events for this city. Besides APMCHUD is an award for Solo urban renewed images since 2005 which one of them is urban waterfront revitalization. Applying the Lourenço meta-analysis for urban growth areas which is specific in urban waterfront management, a better apprehension of the sequence of interdependencies that exist can be addressed to expand the concepts of redevelopment of urban areas. It can be done within a continuum process associated to planning and investment cycles. The applicability of the proposed model is tested by comparing the idealized evolution to the observed urban waterfront in Solo, for a period of eight years, from 2005 to 2013. This enables the discussion of conceptual issues related to the legitimizing of LCA and the present contribution. Although the complete cycle is not yet observable, it is possible to confirm that the relevant nature of this tool allows for an earlier awareness of the cycle progression anomalies and, therefore, a potentially better adjustment between observed and ideal behaviors, if these anomalies are monitored and addressed.This paper will address Solo profile and planning process, major outcomes due to urban waterfront applicability of LCA models and framework for the sustainable management
THE CONCEPT OF UNDERGROUND SPACE DEVELOP-MENT CONTROL IN SOUTHERN BADUNG AREA
Full text linkCulture is a basic component of Balinese people’s lives. All development activities have a purpose relative to the culture and values implicit in the concept of the traditional Balinese spatial plan. However, with changing times, there has been development which is not accommodated in the Balinese traditional spatial concept. This development is underground space development. As a result, the status of this development is pending, based on formal and non formal policies. Besides that, this development is unseen and therefore largely unknown and its suitability to environment hasn’t been measured yet makes its sustainability status is in uncertain state. This paper addresses the concept of controlling the underground space development in the Southern Badung area based on Balinese traditional spatial concept and with a sustainable development approach.The result identified that underground space development in Kuta village was dominated by commercial development as parking lots. There are three zones identified based on suitability for underground space development in Kuta village which are low suitability zone, medium suitability zone and high suitability zone. The evaluation in terms of culture and environmental suitability showed that there were seven priority criteria in formulating the concept of its development, namely: outside of open green place, had mitigation system for disasters, outside of Tahura Ngurah Rai, outside of the coast border, outside of and not directly adjacent to the Holy Region, outside of and not directly adjacent to graves of Kuta. The main result of this research is a concept of underground space development control to create sustainable tourism in Kuta village
CONSERVATION CONCEPT OF OLD KAMPUNG THROUGH THE APPLICATION OF SUSTAINABLE DEVELOPMENT PRINCIPLES AT KAMPUNG SURABAYAN, KEDUNGDORO DISTRICT, SURABAYA
Full text linkKampung Surabayan is one of old kampungs in Surabaya, Indonesia, that has some potentials which can be developed as a sustainable kampung by balancing the environmental, socio-cultural, and economic aspects. In environmental aspect, Kampung Surabayan already has a good management based on various achievements from Green and Clean Competition (an eco-friendly settlement competition) and Safe Kampung Competition which held by Surabaya Government. The historical potential and cultural heritage, cooperative kampung’s residents, unique “kampung” traditions such as "cangkruk" or “free chattering” and "adu doro" or “pigeon racing”, carry social and culture values. Also, the green economy values that come from the resident’s creativity to manage domestic garbages into unique and valuable handicrafts.One aspect that still be left behind is heritage conservation. As an old kampung, Kampung Surabayan should be conserved in order to keep the authenticity of Kampung’s heritage. The potentials of Kampung Surabayan can be integrated by Heritage Tourism Concept to create a sustainable kampung heritage
