IMPACT OF SIMPLE VIRTUAL TECHNOLOGY APPLICATION IN ARCHITECTURAL EDUCATION

The development of technology cannot be separated from the development of science, including the learning method. There is an elective course named Virtual Reality Architecture in Architecture Department of Petra Chrisitan University. This course focuses on the process of learning architecture at the stage of presenting and communicating ideas. The virtual technology used as a learning method includes three types of technology, animation, augmented reality and virtual reality. The three technologies are elaborated as a simulation method. The simplicity of its application can be seen in the support for hardware, software, and special devices used by students in their daily lives. This study aims to test the achievement of goals at the final level of learning. Students who have attended this lecture are then interviewed and observed, in relation to proving whether this simple virtual technology can be a supporter in the learning process in the architecture study program.

THE THIRD SPACE AND THE ROLE OF BUNDO KANDUANG IN RUMAH GADANG

Minangkabau is a tribe in West Sumatra with a matrilineal kinship system, which draws lineage based on the mother's ethnicity. Therefore, women are the main characters in the tribe. Minangkabau women who are married, wise, and elder are called Bundo Kanduang, who have duties and obligations to carry out. Given the importance of the role of Bundo Kanduang, it is necessary to know how the role of Bundo Kanduang can be carried out in the Rumah Gadang, both physically/real and non-physical/imaginary. The research method used is an ethnographic method with a qualitative analysis approach using the theory of the third space from Edward Soja. Based on the analysis, it was found that the activities of Bundo Kanduang in carrying out its role have been facilitated in the Rumah Gadang, both physically and non-physically, even beyond what is known as third space.

COMPARISON OF AIRFLOW IN TYPE 36 LOW-INCOME HOUSING UNIT USING CFD SIMULATION

Type 36 houses are built for people who have low income. Because of this, the buildings’ ventilation relies on natural airflow. One of the variables that affects natural ventilation is airflow. Airflow can affect the quality of indoor air, influencing the comfort and health of those within. This study aims to evaluate the designs of type 36 buildings from the perspective of the airflow through the unit. It uses computational fluid dynamics simulations to compare the pattern and velocity of airflow in each building design. There are six designs of type 36 house that have different layouts and placements of air vents. The results of the simulation and analysis show that rooms arranged in a way that allows for the placement of vents that were facing each other, even if they were in different rooms, generated continuous airflow without experiencing turbulence.

CAFÉ AS STUDENT’S INFORMAL LEARNING SPACE: A CASE STUDY IN BANDUNG, INDONESIA

For the past years, the café's functionality has shifted from serving light food or beverages to being used by students as an informal learning space (ILS). This paper discusses university student's motivation to study in a café and the desired café's characteristics as an ILS in Bandung, Indonesia. The research uses a quantitative method using a questionnaire to reveal the dimensions of students' internal motivation and spatial characteristics of the café and its effect on students' informal learning responses while in the café. Results found 6 (six) groups of student motivations and 7 (seven) characteristics of cafés as an ILS. Results uncover a positive relationship between utilitarian motivation and physical characteristics in the form of the availability and quality of café amenities on students' cognitive and affective responses. It is implied that students choose a café as an ILS because such informal space can provide satisfactory physical amenities so that their learning performance is expected to increase. Through this trend, universities and/or related stakeholders could use this opportunity to improve the well-being of the student.

LIGHTWEIGHT AND MULTI-PURPOSE PARTITION FOR VERTICAL HOUSING

Vertical housings have been developed to solve housing quality degradation due to rapid urbanization. These housings are often lack of privacy and comfort, since the lay-out mostly consists of one open plan space with limited area. This paper presents a lightweight and multi-purpose partition to improve the living quality in vertical housings. The lightweight characteristic is intended to minimize structural loads, while the multi-purpose property allows the partition to be transformed into some furniture for spatial efficiency. A literature review and material surveys were performed prior to material selection and the design process. Then, physical model experiments were carried out to simulate the installation process and the transformation process of the partition modules into some furniture. Result show that the partition’s weight is only 11-36.7% of the common partition wall, and when installed, the transformable property enables an adaptable space which can be adjusted to the occupants’ different conditions.

USER’S PERCEPTIONS OF SACREDNESS (Case Study: Catholic Churches in Indonesia)

Sacredness in Catholic churches has two aspects: sacredness derived from the purpose and activities of worship and sacredness that arises from the physical and spatial aspects of a church building. The purpose of this study was to reveal factors that affect sacredness in Catholic churches from the perspective of the worshiper. The researchers conducted an exploratory qualitative research to collect text data related to the perception of Catholic church sacredness. The data were collected through an online questionnaire. The researchers also conducted an explanatory quantitative research to uncover the relationship between level of church sacredness and physical and nonphysical factors. The results showed that the ‘sacred spirit’ factor tends to be more dominant in affecting church sacredness compared to ‘sacred object’. Worshipers measure church sacredness according to ‘devoted reflection’, ‘relationship with God’, ‘quality of space’, ‘enclosure acculturation’, and ‘building style’.

STUDY OF OPEN-AIR MUSEUM ON KAYUTANGAN STREET CORRIDOR

The Kayutangan Corridor is one of the areas in Malang that holds many historical values, namely as a shopping center in the Dutch colonial era. However, the glory and history of kayutangan began to fade with the times. This research's general objective is to provide a design proposal for the Kayutangan corridor that can present historical stories of the buildings along the corridor, such as an open-air museum, with the building as its object. The research method used is descriptive qualitative research with a signage theory approach. The final result of this study is the proposed signage and pedestrian design in the Kayutangan corridor.

PEDESTRIAN BEHAVIOR FOR DEVELOPING STRATEGY IN TOURISM AREA; AGENT-BASED SIMULATION

Agent-based modelling is an approach to develop a design strategy in socio-related studies to understand pedestrian behavior by using simulation through validation using field observation. This study area has a historic city so that having several potential advantages as destination tourists and also having urban issues. Some facilities disseminate prosperous for domestic tourist destinations, transportation hubs (land and water-based transport), and public facilities. The purpose is to develop a design strategy of pedestrian behavior in urban space to be procedure based on computational modelling. By merging the result, it helps designers to depict pedestrian movement flow, permeability, and connectivity patterns, which represent the presumptions of the origins or source of movement, destinations, generators, and attractors of movement. This simulation examines and valuates spatial behavior models allowing to route preferences of each pedestrian in order to be used in the strategy of design process for architect, urban planner, or other designer stakeholders. The result will imply a walkable pedestrian-way design, where this approach of a pedestrian experience might be an effective tool in city planning.
