Abstract

ABSTRACT Sekolah Alam (The Nature School) is a new concept of school in Indonesia that divide its learning process, both indoor and outdoor. As it needs more outdoor space for learning activity, this type of school has larger yards yet smaller classroom compared to conventional school. As it is still new, no previous study has been done to understand the relation between space dimensions, building material, and surroundings to this school classroom acoustic quality. Therefore, this journal studied acoustic quality by calculating Reverberation Time (RT60) and measuring Background noise value of one typical class of Sekolah Alam in Bandung. Reverberation Time (RT60) was calculated using space dimensions and materials that exist within the studied classroom, while the background noise value was measured using Data Logging Sound Level Meter (SLM). The results indicate that the studied class has an ideal acoustic quality for learning activity. The main factors that affected these results are the classroom has a small size in volume and surrounded by lush trees which work as noise controls.

Abstract

Famous for its large rivers, Kalimantan is one of the islands in Indonesia that is characterized by a river-cultured society, where lanting or floating dwelling is one of various types of river settlements that represents a unique but also complex relationship between man and river. Despite their existence being in line with the historical development of river cities in Kalimantan, today’s urban lantings have come to be stigmatized as slums, due to society’s biased perspectives, and the dominance of the planning paradigm that is oriented towards “modern” land-based urban planning. Using the qualitative historical analysis method in the case study of lanting dwellings in Sintang, West Kalimantan, this study interprets the analytical dimensions of the complex relations between space, power and resources, which changes over time. Exploring the political-economic and ecological history shows the long journey of lanting’s existence that gave understanding of today’s lanting conditions, as well as understanding about the development of the cities themselves. This study concludes that the concept of river cities or waterfront cities in Kalimantan should be understood in a broader sense, beyond merely aesthetic and environmental considerations. Riverine settlement has deep historical roots in many Kalimantan cities and also represents complex relationships between city-hinterland and river-related urbanization process under the political-economic and ecological changes. Thus, consideration of the diachronic aspects of city-river relations should be an important basis for planning future Kalimantan cities.

Abstract

Abstract–Wood consumption as building material and component in Indonesia is still considerably high. This affects forest destruction, in a way that most of the wood production still roots from wood forests. Hence, the demand of these woods better be supplied from other source, one of them is through using used woods. Used wood utilization in building construction is an application of reuse and recycle strategy in sustainable material concept. Due to the assumption among the people that used woods have low performance its utilization is nowadays limited. This paper addresses the result of research and laboratory test on a range of used wood samples collected from Jakarta great area (Jabodetabek), consist of 5 technical parameters: water content, density, compressive strength, flexure strength, and tension strength. The research proves that based on certain parameters, used woods perfom technical capacity as good as – or even better than – newly produced woods.Keyword –  sustainable, material, used wood

Abstract

Abstract—PET plastic bottle is one of the main source of  waste in big cities. This research aims to find out the possibility of reusing PET bottle as pre fabrication wall module material. The pre fabrication concept were offered so that in the construction phase, the instalation of this material will be fast, efficient, and able to minimalize the waste potential. The method to decided the PET bottle specimen was by surveying some sample location in Jakarta to found out the type and capacity of PET bottle waste. Bottle waste that has the highest volume, was selected to be the speciment for further experiment as pre fabrication modul. To determine the strength capacity of this material, some module variation were designed for compressive and flexural strength test. This research is a preliminary experiment to understanding the basic potential of PET bottle as building material. This research expected to support the use of PET bottle waste for other uses in building constructionKeywords— reuse, PET bottle, pre-fabrication, module.

Abstract

Urban kampung in Indonesia has the characteristics of a high population density living in a limited amount of land. Residents of an urban kampung require a space that can be used together to carry out communal activities. However, the limited amount of land in a kampung causes these activities to occupy whatever land is available which often has uncertain ownership status. A team from the Department of Architecture UI built 'Popsyandu' shelter in Kampung Palsigunung, Depok, West Java, using the 'flexible architecture' approach to respond to the needs and issues of the kampung. Using qualitative methods and data collection through observation and interview, this paper attempts to discuss the application of flexible architecture in the design of 'Popsyandu'. The result shows that the application of 'flexible architecture' approach is difficult to be comprehended by the residents of the kampung, even though the designers tried to involve the residents during the design and construction process. Therefore, the authors conclude that in adopting a flexible architecture to respond to certain issues, the designer must consider the capabilities of the user instead of just following the theories stated beforehand. © 2020 Dalhar Susanto, Widyarko, Nisrina Dewi Salsabila

Abstract

There is a recent focus on households as residential units but most of the studies conducted rely on demographic and economic perspectives using economic value maximization schemes. The research on the household is considered necessary due to its close relation to family and kinship issues observed in different aspects of life and based on societal diversity associated with certain socio-cultural values. This is most important in Asia, including Indonesia, where extended families and households are regarded as ideal. Therefore, this study was conducted to understand the significance of socio-cultural values ​​on the spatial living implications in extended households using qualitative methods, especially ethnography, which involved targeted informants, interviews, and observations. The results showed that the socio-cultural values ​​held by the members of the household are based on the definition of kinship as a valuable bond, desire to share, cooperation, as well as the acceptance and sustenance of tradition. Moreover, the spatial arrangement concerning the allocation, use, and access to rooms based on gender in an extended family was observed to be identical to those in a nuclear family. Meanwhile, additional members are allowed to use different rooms in the house and also to interact with hosts.

Abstract

The palm oil plantation in Indonesia is an overgrowing industry that also poses significant environmental waste problems. The industry produces numerous unused biomass wastes such as EFB (Empty Fruit Bunch), PKS (Palm Kernel Shell), tree trunks, fronds, etc. On the other hand, the national housing backlog number in 2019 had reached 7.6 million units. The government had launched several housing programs to tackle this ever-repeating issue. Yet, all of the plans failed to solve the housing shortage. A new approach is needed to provide a cheap, affordable, and more environmentally friendly affordable house. Previous studies proved that palm oil fiber waste could be altered into building materials such as lumber and other biocomposites like particleboard, fiberboard, plywood, etc. Consequently, by using the construction scheme in the RSH affordable house program released in 2002, palm oil fiber waste should be able to displace conventional wood in most of its parts. That is why there is no reason to halt implementing palm oil fiber waste as building materials, especially to build an affordable house. Therefore, the burden of Indonesia's never-ending housing backlog problems should be eased by converting its over-abundant palm oil fiber waste as its building materials new renewable sources.Keywords: affordable house; alternative materials; bio-composite; palm oil fiber waste
