Evaluation of OTTV Values on Window to Wall Ratio at Abdi Siswa Catholic School Patra Unit, Jakarta

2024-10-18T17:30:01+00:00

OTTV (Overall Thermal Transfer Value) is closely related to WWR (Window to Wall Ratio) and the lighting level of the rooms in it. The OTTV value is directly proportional to the WWR but inversely proportional to the level of lighting, which makes it a challenge to design buildings that have OTTV and lighting according to SNI benchmarks. School buildings whose main activities are learning really need adequate lighting levels to support the productivity of their students, and it is urgent to carry out this research. Using the OTTV standard from SNI 03-6389-2011 with a maximum value of 35 W/m² and room lighting levels from SNI 03-6197-2000, quantitative evaluations and recommendations were carried out at the Sekolah Katolik Abdi Siswa unit Patra using statistical analysis methods to calculate the OTTV available as well as recommendations and experimental methods to find a balance point between OTTV and lighting levels. The update of this research is in the form of research stages that take from the existing building being evaluated, not a new building to be designed. The research focus is also more on changing the level of lighting than the recommendations. The results show that the existing OTTV values of the research objects have met the standards, but the lighting in the rooms where students study is still below standard. Recommendations were made in the form of changing WWR, glass type, and adding artificial lighting as a last resort to achieve sufficient lighting with substandard OTTV. The conclusion shows that classrooms, libraries, and laboratories can reach 30% area with standard room lighting and standard OTTV values. It can also be concluded that the design of green buildings is not only limited to reducing the OTTV value to a minimum but also must pay attention to the level of lighting that is imposed by decreasing WWR.

The Kinship and Rank in the Layout of Bawean Traditional House, East Java Indonesia

2024-10-18T17:30:43+00:00

Introduction/Main Objectives: Traditional houses in many places in Indonesia have a very strong attachment to Family and also with neighbors. The Family in each region of Indonesia has a specific term of social organization and Kinshop that occurs in each traditional House in Indonesia. One of is a Traditional house in Indonesia that apply Kinship and Rank in their traditional houses is Bawean houses on Bawean Island in East Java, Indonesia. The Kinship and Rank applied in the lay of Bawean traditional houses. Each House has many meanings depending on the family group. Each of the Unit houses is confined by a granary named Dhurung in the front area Background Problems: Unfortunately, The condition of Bawean houses is now rarely found and only 3-4 houses remain in each sub-district. Novelty: This paper would like to highlight the findings from the survey of Bawean Houses and its kinship as documentation and study so that they can be understood by the wider community. Research Methods: Qualitative data collection was used by observing and interviewing the local people who still live in the traditional Bawean House. Finding/Results: The data in this paper as a result will enrich the classification of kinship in the traditional house on the Small island of Bawean island Conclusion: Kinship and Rank in Layout Bawean traditional houses are made based on the floor plans of the rooms in a traditional Bawean house, which is continued by laying out the house behind the opposite and so. This Bawean house adds a new finding to strengthen the kinship and rank in South Asian houses kinship is not only the design of the physical structure but also respect of the neighbor-by-house zones that appear in the floor plans. The Kinship and Rank in Bawean traditional house zone their plan to strengthen the kinship relationship with the next house that still has the family connection with the house.

Multi-sited Qualitative Research in Architectural Study

Migrants' place to live in destination city belongs to study of architecture as it concerns spatial mobility implicating a certain built environment in destination city. This article concerns the issue of spatially dispersed migrants with particular reference to one of prominent migration destinations in Indonesia, namely Balikpapan East Kalimantan. This article aim to present the exploration of research site selection as well as its methodological consideration to tackle the aforementioned issue. To do so, it employs and highlights the prominence of multi-sited qualitative research, especially the notion ‘follow the people’. This article follows guidance of bodies of studies categorised as methodological reflection, putting forward the narrative genre of presenting.

Optimizing Opening Design for Daylighting in School Buildings, Case Study: Xaverius 3 Palembang Senior High School

2024-10-18T17:33:11+00:00

The school serves as a facility to accommodate teaching and learning activities. The efficiency of these activities within the classroom is influenced by the illumination in that space. Classrooms with more natural lighting allow students to learn 20% more efficiently compared to classrooms with less natural lighting. However, many classrooms still rely on artificial lighting, such as lamps. Apart from reducing students' learning efficiency, the use of artificial lighting also diminishes energy conservation in school buildings. Therefore, this research aims to analyze the optimization of aperture design for natural lighting in classrooms. The case study involves Xaverius 3 Palembang Senior High School to identify the focus of this research. This school is chosen because it uses artificial lighting in classrooms despite having windows on each side of the room. In the data analysis process, this research employs an experimental research method by modifying the most efficient aperture design for natural lighting, targeting an average of 350 lux. The experiment utilizes Dialux Evo software to simulate natural lighting levels in the classrooms. Through this process, it is found that various factors influence natural lighting levels in a room. The building's mass shape and orientation are fundamental factors in optimizing natural lighting. The dimensions of openings and the use of shading are other factors affecting natural lighting levels in a room. Therefore, designing the most efficient opening requires a combination of appropriate opening dimensions and shading usage, maximizing the potential of natural lighting based on the building's mass shape and orientation.

Urban Built Environment and The Emergence of Working Women Alienation in Sudirman Central Business District, Jakarta

2024-10-18T17:41:20+00:00

This paper examines the phenomenon of alienation among working women in urban spaces, focusing on Jakarta's Sudirman Central Business District (SCBD). The study aims to enhance understanding of how the built environment contributes to the alienation of working women and provides insights for urban design to create more human-friendly spaces. The commodification of urban spaces prioritizes economic interests, leading to environments that marginalize and alienate minority groups, including working women. The paper seeks to answer how does the urban built environment in SCBD contribute to the alienation of working women?

This paper explores the intersection of urban design and the social experiences of working women, an area relatively under-researched in architectural studies. While previous studies have focused on social and literary approaches, this paper integrates architectural perspectives with social analysis to provide new insights. Utilizing a constructivist paradigm, this qualitative study employs a theory-driven case study method. Data collection involves field observations and documentation of SCBD's built environment. Descriptive and exploratory analyses are used to evaluate the built environment's physical characteristics contributing to alienation.

The study identifies several factors contributing to alienation, including the intimidating scale of buildings, lack of public spaces, objectifying advertisements, and high-density conditions. Some design strategies to mitigate alienation include creating street furniture at a human scale and adding active security measures such as CCTV and lighting. The findings suggest that urban design must prioritize human needs over economic interests to reduce alienation. Further research, including interviews with working women, is suggested to deepen understanding the connection of psychological experiences and the built environment.
