COMPARISON STUDY OF CONVENTIONAL AND BIM BASED APPROACH IN ESTIMATING THE CONSTRUCTION COST OF SUBSIDIZED HOUSING

2024-12-27T14:06:04+07:00

BIM has been wide used the achieve and effective and productive construction. Construction technology is one of the construction methods to increase productivity. Stakeholders are required to complete the project in a short time and with optimal results. One way to improve performance effectiveness is to apply the Building Information Modeling (BIM) method to quantity calculation work in order to increase work effectiveness. This study aims to compare the conventional and BIM methods. The object of this research is subsidized housing in Central Java. In the project completion process, the calculation of the volume of the roof, walls and floor uses the conventional method. Then an evaluation was carried out using the BIM method and a comparison was made between the BIM method and conventional methods. Between the two methods, the BIM method has an average accuracy rate that is better than the manual method. The results of the study show that the comparison of the cost of subsidized housing that is measured by BIM and conventional has a significant difference. Comparison of the total budget plan using the Building Information Modeling method is lower than the conventional method, namely the difference more than 1 billion.

ENHANCING SUSTAINABILITY THROUGH SLUM SETTLEMENT UPGRADING. CASE STUDY OF KAMPUNG MOJO, SURAKARTA.

2024-12-27T14:05:03+07:00

The redevelopment of Kampung Mojo is one collaborative design project aimed at improving the quality of slum settlement by supporting basic infrastructure and providing housing. This study focuses on three pillars of sustainability: social, economic, and environmental, by exploring the usage of outdoor space following the upgrading process. The objective is to gather insights that cater to the community's needs and foster the realization of sustainable settlement. The method used in this study is qualitative descriptive with data collection techniques through observation and interviews. The findings of this study underscore a diverse array of activities that yield positive implications for raising the sense of communities, creating new economic opportunities, and productive land usage to achieve Sustainability Development Goals (SDGs).

IN-FILL DESIGN IDENTIFICATION AS PRELIMINARY STUDY OF HERITAGE SITE CONSERVATION IN BOROBUDUR AREA

2024-12-27T14:06:25+07:00

Hold a rural architecture atmosphere as their attribute, Borobudur Temple Compounds area facing urbanize impacts by massive development that threatened that attribute. Where this compounds has been registered as a World Heritage since 1995. The such as in social, political, and economic sectors, including architecture as well as regional layout. This issue becoming a big threat to the architecture preservation in the region. By using several parameters and virtual reconstruction as an identification tools, this research stand as an effort to preserve in the form of documentation. The process was carried out by directly visiting several villages in the Borobudur temple compound area and continued by conducting digital modeling and drawing. Most types of buildings have a gable roof but some deviations are found in a small part of the observed objects. This research identified the variety of infill design; space arrangements, construction structures, and aesthetic elements. On the other hand, this also a critics for government documentation and regulation regarding local architecture surrounding. This research final aimed to be positioned as a prelude to the data documentation stage in the Heritage Impact Assessment (HIA) process.

Potential of Wood Modification Technologies on The Physical and Mechanical Properties of Albizia Falcataria: A Literature Review

2024-12-27T14:05:46+07:00

Wood modification treatment has grown in popularity over the last few years and continues to expand as an industrial method for improving certain types of wood. As a result of environmental concerns, the wood sector is under more pressure than ever to develop wood alternatives. Nowadays, fast-growing wood species appear to be increasingly potential as substitute wood sources for bridging the supply-demand gap in the wood industry. Albasia (Albizia falcataria), sometimes known as sengon wood, is a fast-growing wood widely planted in Indonesia. However, specific characteristics of the wood, such as low density, low hardness, and low strength, have been hindering its end-use applications as a building material. Therefore, numerous technologies are utilized to enhance wood's physical and mechanical qualities. This paper summarizes the extensive literature on wood modification of Albizia falcataria and synthesizes the major publications on wood properties, chemical changes, wood uses, and quality control. Acetylation, furfurylation, thermal modification, and impregnation as wood modification technologies have been utilized in Albizia falcataria studies. Based on recent investigations, this article aims to review the current state of knowledge regarding the wood modification technologies for improving physical and mechanical properties of Albizia falcataria. Identifying the gaps in research would also aid in accelerating the research activities for deploying these modification technologies on an industrial scale.

READING OPENING THROUGH MULTIPLE ARCHITECTURAL PERSPECTIVES:

2024-12-27T14:05:27+07:00

Most architectural designers develop an opening based only on its function and form. Other exciting things can be created further by exploring an opening. An opening is crucial as a design element to complement user activities and interactions. This paper examines ways to read openings from various architectural perspectives. Observations were carried out on objects in the form of several commercial buildings in Yogyakarta as a research method. The research results through the multi-perspective reading of the morphology of an opening show the influence of transparency, dimensions, shape, system, supporting components, opening height, and opening view framing in providing meaning and added value. The exploration that has been carried out then provides an understanding that the opening is not limited to its primary function as ventilation and lighting but can more broadly include the influence of its morphology on the perception it creates as a complete design presentation.
