Previous researches on urban housing transformation in Indonesia focused on the privacy and observable morphological changes of the house. This study aims to compare the spatial configuration between the original and transformed plan of the urban houses in Indonesia. Six houses in Jatiwaringin Asri, Bekasi were investigated as part of the case study. The original plan and transformed plan of the houses are obtained through the interviews with the occupants of the houses. The plans were analyzed graphically and mathematically using space syntax. The results show that the open plan space is central in both original and transformed plan. There is strong segregation between public and private area but the interior of the houses maintain low hierarchical organization.
Virtual reality (VR) technology allows the reproduction of spatial experience in a digital environment and simulates both real and imaginary world experience. The experience is created for various devices with different degrees of immersion. Several use cases of VR utilization have been explored in the architectural field, including historical buildings exploration in a distant place. However, VR is often associated with high investment in hardware and software. This study demonstrates VR utilization to experience off-site exploration of architectural heritage using a low-cost hardware setup and open-source software. We propose the possible workflow to create VR assets using Blender. Furthermore, we investigate the authoring pipeline to optimize the model for various devices. The result will be deployed as a VR environment under Mozilla Hubs, a WebXR-based platform that users can access simply from a web browser. With this workflow, the goal is to provide a low-cost VR experience for everyone where the environment can be easily accessed using the available existing device.
Space syntax adalah perangkat teknik analisis ruang yang dikembangkan untuk mempelajari hubungan antara tatanan masyarakat dengan konfigurasi ruang. Metode analisis yang digunakan fokus pada kualitas topologis ruang dengan mereduksi denah bangunan atau ruang menjadi diagram yang mengidentifikasi keberadaan ruangan dan koneksi antarruangan. Walaupun space syntax telah diperkenalkan sejak tahun 1982, penggunaannya terbatas karena pemula tidak memiliki panduan praktis untuk memahami proses analisis langkah demi langkah. Penjelasan teori space syntax juga memiliki inkonsistensi teori sehingga sulit dimengerti. Tulisan ini ditujukan sebagai pengenalan dasar pada pemula yang ingin mempelajari space syntax. Konsep dasar mengenai teori space syntax akan dijelaskan lalu dilanjutkan dengan studi kasus untuk menjabarkan teknik analisis yang digunakan. Dengan fokus pada teknik convex mapping, proses analisis akan dijelaskan langkah demi langkah untuk memperkenalkan pemula pada konsep dasar analisis dan interpretasi visual terhadap hasil analisis. Proses analisis yang digunakan mencakup tiga bagian: abstraksi, analisis, dan interpretasi. Pada tulisan ini, fokus bahasan hanya pada analisis visual tanpa membahas analisis secara matematis.
Activities in the dwelling are inseparable from housing design. Spatial features often result from patterns of activities that take place within the dwelling. Activities are further elaborated to affect house plans, furniture, arrangement, and equipment. However, discrepancies still exist between housing design and behavior, where housing design often fails to accommodate activities and behavioral dimensions within the family and the dwelling. This paper addresses the relationship between dwelling activities and housing design by means of a qualitative study that aims to understand the needs of the Indonesian dwelling through activity analysis. To do so, the research adopts a methodology that involves collecting data from measurements of the house, house plan analysis, and photographs, in addition to in-depth semistructured interviews with families. Taking Bandung as a case study, 9 houses and families were selected as respondents that share similar family life-cycles, number of family members, and building size. The findings from the study suggest that spacious and open plans are preferred by the family, while maintaining family privacy. Guest areas are used to host formal guests and to restrict visitor access in the house. Service areas such as kitchens and laundry areas are the core areas for household activities for cooking, laundry, and drying. To meet social activities such as community gathering, open plan design is necessary to allow flexibility of furniture reconfiguration to accommodate extra guests.
Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
