RECONNECTING JAKARTA : A CATALYTIC PUBLIC SPACE

Urbanization has been a major global issue, especially in the 21 st century. This rapid urbanization drives a massive amount of population movements to urban areas and its peripheries, and drastically increased urban density. Although it rises several values and strengthened local economic power, urbanization causes degradation on the spatial discourse. Most urban spaces nowadays are formed by economic-driven factors, and leaving the importance of social relations behind. Urbanization and economic growth in urban areas -- especially in nation’s capital like Jakarta -- resulting a high gap or inequality. The existence of kampong and the modern city reflects the spatial segregation and socio-economic disparities. This leads to social exclusion, where the urban poor are marginalized and alienated from their neighborhood. While the physical separation is inevitably seen, low intensity on social interaction is one of other form of restrictions. The proposed object is a mix function between an outdoor public space and community center, to create a social space that could triggers interaction between social classes and increases social relations. Using urban catalyst studies, this project tries to produce an activity generator. So that the economic-driven urban spaces are not seen as a boundary, but could functions as a social catalyst.

. Firman (2000) argues that the existence of kampong and modern city reflects the spatial segregation and socio-economic disparities.

I.2.4 Proposed Object
The proposed object is a mix function of an outdoor public space and a community center aims to creating a social space that could triggers interaction between classes in the neighborhood.This project is also meant to be a linkage between economic-driven urban spaces and middle-low community residential, so that these spaces are not seen as a boundary, but could also functions as a social catalyst.

I.3 Design Goals
This project aims to create a social space that could triggers interaction between social classes and to stimulate movement.It is also designed to be a linkage between shopping centers, apartments, office building and middle-low community settlement, so that the economic-driven spaces are not seen as a boundary, but could functions as a social catalyst.

I.4 Design Criteria
-The design should be flexible, anticipate people from all social classes, ages, and conditions.
-The design should be a linkage; links surrounding buildings and houses.
-Becoming a focal point in the area.
-Could accommodate interactive activities for the users.

II.3.2 Access
The main road, Jl.Teluk Betung I located on the northern part of the site is 9m-width two-way road.
It is also accessible to reach the site from the east side, Jl.Kebon Sayur, although it is limited for motorcycle and bicycle only because of its quite narrow width.On the existing area, Jl.
Kebon Sayur is actually accessible for cars, but would not be recommended for this project's circulation.This bridge will be the main access for four-wheel vehicles, while the eastern and northern part of the site will prioritize pedestrian.The basic questions to be asked are :

II.3.3 Climate Analysis
How do people interact with the built environment?What are their needs?
How do we apply such understandings in the design process?(Moore, 1979).
Environment-behavior studies encompass more than just function.
Behavioral factors go deeper, to the psychology of the user, how he or she perceives building form, social interaction needs, subcultural differences in lifestyles, and the meaning of symbolism of buildings (Moore, 1979).

CHAPTER VI CONCLUSION
This project came up with an idea to tackle social exclusion that exists in Tanah Abang area.By using environment-behavior and urban catalyst approach, this happen to be an activity generator that could triggers interaction in the community to support a more inclusive neighborhood despite all differences.It could also add a social value that is barely seen in surrounding economic-driven spaces.
Community center that integrated with green public space designed as the social catalyst.Flexibility appears as the core concept with focuses on accessibility, comfortability, interactive spaces, and borderless values for the design decisions to achieve project's goals.The community center building has a continuous ramp, which allows people of all conditions to feel the entire space, and to creates more interaction between people.This also acts as the attractor and focal point of the public space.
Urban Catalyst approach was chosen since it is contextual to the problem that is exists in surrounding area, and reflects values of the word catalyst itsel, which causes activity between two or more persons/matters without itself being affected, or in this context, without changing social culture that rooted in local community.

Figure I. 1 Inequality in Tanah Abang, Central Jakarta Exclusion or social marginalization in general is a process that deprives individuals, families, and groups of the resources required for participation in the social, economic, and political activity of society as a whole.This mostly caused by ascension of individualism in urban society, poverty, low income, and several other causes.

Figure I. 2 From Poverty to Social Exclusion Activities in the proposed object is majorly divided into 2, main activities and supporting activities.Main activities are activities related to the aim of this project, while the supporting activities are including administration & security, praying, service and maintenance.

Figure III.1 Environment-Behavior Approach (Garry T. Moore) This project focuses on how to create interaction between social classes, to perform a more inclusive city.In order to achieve that, we need to understand the relational dialectics between people of different classes and space through behavioral approach, to finally understand what needs to be provided in the proposed space.A useful model for seeing the scope of available environmentbehavior information, first proposed by the architectural psychologist Irwin Altman, includes three main components:
