Abstract

The development in construction industry in recent times show the tendency of segregation in industrialization process. This research observes the segregation phenomenon of  innovation adoption on small scale construction project as like as segregation phenomenon of construction industry at common. Case study in this research is Musholatorium, which is an abbreviation of Mushola (prayer room) with planetarium, in Lembang Bandung. The innovation on this research was the geodesic dome structure as a Musholatorium. The method used in this research consisted of: (a) describing the project and (b) analysis. The project process consisted of (a) initiation, (b) architectural design, (c) component design, and (d) component fabrication and construction. From the analysis, it could be suggested that there are inefficiencies of knowledge distribution during the project process since the knowledge was transferred without sufficient collaboration. Only the owner involved during the whole process and could actually conclude the whole to develop the innovation. The nature of construction project, which usually be segmented, caused the inter-discipline aspect hard to be communicated between actors. In order to introduce innovation into building construction project, it is important for the actors to involve and collaborate inside the projects as a collective works.

Abstract

Genius loci merupakan konsep keunikan suatu tempat, yang terbentuk karena dialog antara lingkungan alam dengan lingkungan binaan. Genius loci kampung Areng di Lembang terbentuk karena munculnya fasilitas eduwisata astronomi di kampung ini. Objek studi kajian ini menelusuri genius loci Imah Noong sebagai tempat wisata bertema astronomi. Metode yang digunakan dalam kajian ini adalah metode deskriptif kualitatif dengan pendekatan place making. Genius Loci dari wisata astronomi Imah Noong dilihat dari image, character, space yang terbentuk di kawasan tersebut. Dari kajian tersebut, ditemukan bahwa genius loci Imahnoong terbangun karena adanya banyak aktivitas wisata yang terkait dengan aktivitas pendidikan, sosial, dan ekonomi. Perpaduan antara lingkungan alam pegunungan yang pas untuk aktivitas wisata astronomi yang dipadukan dengan aktivitas pendidikan, sosial, dan ekonomi menjadikan keunikan bagi kawasan Kampung Areng.

Abstract

==========================================================Available online: 09 April 2018 This article has been retracted by Indonesian Journal of Science and Technology Editorial team, following clear correspondence and confirmation with authors. The paper is retracted from 30 May 2021.==========================================================Bamboo applications become popular recently by the community due to the rise of environmental awareness, including for post-disaster building. Two aspects of post-disaster buildings were considered: i.e. its performance and its recyclability. This research explore ability of bamboo as tensile structure, and also as knock-down structure. Bamboo radial compression (barcom) connection was explored by these aspects. Barcom joint is one of the solutions to be  effectively used for gaining the tensile strength of bamboo by converting tensile load parallel to fiber into radial compression perpendicular to fiber. Barcom joint was tested to acquire its load capacity and its future improvement. The load test showed that the barcom connection could reach up to 21.61 kN. To improve this capacity, either better wire or special washer design could be proposed. The adaption in previous built structure (i.e. Three Mountain Building in Serangan island, Bali and knock-down bamboo geodesic dome in Colombia) was used as a case-study. In the construction of Three Mountain Building, barcom joint was used to hang the bamboo rafters and acts as tension-like member. Meanwhile, the use of barcom joint in Colombia was intended to connect the bamboo with the steel bowl connector which could be dismantled and reused again many times.

Abstract

Engineered wood has significant potential to support low-carbon construction in Indonesia; however, its adoption in the residential sector remains limited due to uneven knowledge distribution, concerns regarding durability, and limited ecological literacy. This study addresses the gap between the technical potential of engineered wood and its low level of acceptance by examining how material characteristics and adoption challenges influence user interest, with ecological perception considered as a mediating factor. A mixed-methods sequential explanatory design was employed, beginning with a qualitative phase involving 115 respondents through an open-ended online questionnaire, followed by a quantitative survey of 116 respondents. Data were analyzed using Exploratory Factor Analysis and multiple regression. The results show that knowledge of engineered wood remains segmented, with higher levels observed among highly educated respondents, formal-sector workers, and urban residents. Material perceptions are positively shaped by technical attributes such as strength, dimensional stability, and thermal performance, while concerns related to long-term durability and initial cost remain key barriers to adoption. User interest is influenced not only by technical understanding but also by ecological awareness and professional experience, underscoring the importance of social and psychological factors in material selection. These findings highlight the need for integrated educational and policy strategies that enhance sustainability literacy, strengthen technical confidence, and support the wider adoption of engineered wood in Indonesia’s low-carbon housing development.

Abstract

Timber has been used in traditional Indonesia short-span roof structure. This short span timber structure still depended on the maximum length and thickness of the timber. Despite the introduction of the trusses system, timber constructions are still limited to short span roofs. Steel and concrete are still more popular to be used as long span roof structure material. This phenomenon was also shown in mosque roof structure development. The timber roof structure was replaced by steel and concrete long span roof, especially in form of dome structure. This paper presents the complexity of design to construction process of Nurul Hasanah Aceh Mosque in Palu City which pioneers the long-span single-layer folded grid timber roof structure in Indonesia. This article discusses design exploration of the mosque which showed the inseparable structural, construction, and architectural aspect in design process. The construction could serve as milestone for the development of long-span timber roof construction in Indonesia. This article also recommends several technical and computational improvement to further develop complex long-span timber structures in Indonesia.
