Bandung got the 4thrank as a populated city in Indonesia, and similar with many Indonesianbig cities, especially in Java Island face the complex of demographys problem on an urbanspatial structure associated with the population growth, such as land use, water supply,equipping settlement and its facilities. Bandung is clustered of urban village, which is spreadacross the city, formed in the strategic point of downtown. Tamansari is one of many urbanvillages in Bandung, that have a strong historical correlation with Bandung development,even to the present. This phenomena was made the environmental chaos of the central citybecame linked to the social problem of urban life.In addition, claims about higher densitiessuggest benefits in energy savings through combined heat and power (CHP) provision, butthat benefits might be outweighed by the loss of open space. (Moughtin, et al. 2005). Thisprovision of open an especially green space is included: reduced surface and airtemperature, due to daylighting, high humidity, effect of the wind tunnel.Physically, these villages even look like a slum area, and somehow this area is an easytarget to be displaced, mostly changed into commercial function, because its land value.However, it's just like changing a mask without solving the problems of a settlement area,kind a move the slum area to another place.The uncontrolled urban structure of high density urban villages due to the population growthmake the writer wanted to know about the environmental implications of urban form forparticular combinations of building types, urban forms and open spaces.

A. INTRODUCTION
1. History of Cikapundung Taman Sari community around the river bank
The city history dates from 1488 when the first reference to Bandung exists, but from ancient
archeological finds, we know the city was home to Australopithecus, Java Man. These people
lived on the banks of the Cikapundung in north Bandung, and on the shores of the Great
Lake of Bandung. Flint artifacts can still be found in the Upper Dago area and the Geological
Museum has displays and fragments of skeletal remains and artifacts.
Since the early 20th
conservation ecology of Cikapundung River has been the priority through
the Committee of Van Leeuwen, who has compiled Cikapundung watershed conservation
program includes the following activities: Zoological Garden (Wildlife Park) and Mini
Botanical Garden (Botanical Garden "mini") greening the land on the banks of Cikapundung,
from Maribaya to Taman Sari. Tamansari then serves as the "Forest City", which
accommodates 1200 plant species. It was start from the rebellion of DI/TII in the early days of

the revolution in Garut, Sumedang, and other outskirts of Bandung, which caused many
residents to flee to the city center. Then the many refugees who settled until now, and up to
now they claim native to this area.
Part of Cikapundung River is Tamansari area, and here is the high density of urban village in
Bandung. Tamansari right now has gradually changed from a green area of the city into a
dense residential. Its strategic location and lack of planning and control tools that anticipate
the development of the region, this is cause Tamansari decrease as physical quality,
environment and social. In addition, there is transfer of land use than they should be open
space and greenery that protect ecosystems along the river, has been transformed into
uncontrolled and an irregular residential which are very dense.
This history of Cikapundung and the community who live around Cikapundung then drive the
writer to know the urban structure of this area, since there are a big transformation from
Forest City become a high density of urban village
2. Problem Restriction and Formulation
The study of urban spatial structure will cover a very
broad spectrum of issues, this is refers to a cluster of concepts
concerned with the arrangement of urbanpublic space.The way
that urban public space is arranged affects many aspects of how
cities function and has implications for accessibility,
environmental sustainability,safety,social equity, social capital,
cultural creativity and economics.
The first limitation relates to the area of study, which is serially
north, south, west and east are bounded with Jl. Siliwangi, Jl.
Wastukencana, Jl. Cihampelas and Jl. Tamansari.
The second limitation, related to the problem. In the context of
architecture, this research is limited in characteristic of urban
structure physically which is influenced by the density of urban
built and architecturally to improve the quality of the city. This
aspect includes two things. First, the anatomy of the quality of
the city, which adopted an indicator of Shirvani (1985) and Urban
Design Compedium (2000). Second, the identity architecture, which adopts the concept
image of the city of Kevin Lynch (1981) and place of Mark Zanhd theory (2003).

On that basis, the main problem then is formulated as follows: " To what extent and in what
ways does urban form contribute to the quality of city life and find the optimal approach in
addressing the problems of urban village
Based on these major issues, reduced to some sub-problems:
a. The description of physical characteristic of Tamansaris urban form such as
size, shape, scale, allocation and land use, type of building, layout of urban blocks, the
distribution of green space.
b. How to assess the physical condition of Tamansari in order to improve the quality of city
life?
3. Hypotheses
This research is built around the hypothesis that urban spatial structure has strong correlation
with the quality of city life. The increase of population in Bandung has give occasion to createthe growth of uncontrolled settlement. Taman sari as one of urban village in Bandung has
fulfill demand of land use, economical requirement, and shape the unique social community.
The lack of government surveillance of house construction has create many clustered slum
urban village. It signed with unorganized urban spatial structure, such as : building
orientation, height and width of building, and street width.
B. RATIONALE AND STATE OF RESEARCH
The major research question addressed is: To what extent and in what ways does urbanform contribute to the quality of city life and find the optimal approach in addressing the
problems of urban village ? This question derives from the aim purpose of this research
which is finding the implication of urban spatial structure for particular combination of building
types, urban structure and open space to the quality of city life. It is important to tackle and
addresses several gaps in knowledge identified from analysis and review of research in the
field. The sections below indicate some of the key problems that led to this research
question.
1. Urban spatial structure the physical aspect of city life
The term urban form can be used simply to describe a citys physical characteristics.
However, urban form is closely related to scale and has been described as the
morphological attributes of an urban area at all scales (Williams et al., 2000)1
1In Jenks, Mike, 2010

generally encompasses a number of physical features and nonphysical characteristics
including size, shape, scale, density, land uses, building types, urban block layout and
distribution of green space.
Buildings are the most pronounced elements of urban design - they shape and articulate
space by forming the streetwalls of the city. Well designed buildings and groups of
buildings work together to create a sense of place. In contrary, urban high density and
unorganized building form could generate the lost space. It applies equally to all places - to
the centre and the suburb and everything in-between and to the city, town and the village.
Urban structure is important because it provides the foundations for the detailed design of
individual developments enabling (Shirvani, 1985) :
Integration with surrounding area
Individual elements to function efficiently together
Environmental harmony
A sense of place
Commercial viability
Thus, when we talk about the shape of the city then we are indeed talking about the quality
of the city in accommodating the quality of life of its citizens. Respect of this,
Shirvani (1985) states that the quality of most cities at least is determined by three
factors. First, functional quality, in the sense that the quality of a good city if the
spaces between buildings, a liaison system between the buildings, as well as liaison
with other city systems, work well too. Second, visual quality, including aesthetic
environment, namely the appearance of architecture on the scale of urban areas and
not visible from the building unit.
2. The Identity of Place
The shape of city as mentioned above by Jecnk, showing a good connectivity between
spatial and social order. More clearly, Ardrey in Lawson (2001), shows that the need
for stimulation, security, and identity that shape social life, is determined by the spatial
layout, such as shape, size and scale that is perceived by the user.
The concept of architectural identity is adopting the concept of "image of the city"
from Kevin Linch (1981) and the theory of "place" from Mark Zanhd (1999),
which states that the architectural identity of meaning and feelings associated with the
user about the place (sense of place) and the image of architecture, where a person know

and understand their environment, because it has a special character, uniqueness, or
a certain clarity.
Variable identity of architecture consists of three indicators: (1) indicators of identity itself, in
the form of understanding based on the identification of objects, typical of places / regions,
and differences between objects, with the criteria of historical context, cultural, and social,
(2) indicators of the structure vision of patterns, relationships between objects, and inter-
subject-object, with criteria: path, edge, district/sub regions, node, and landmarks,
(3) Indicators of meaning, the form of experience on the meaning of the object, subject-object
meanings, feelings about the place, precedent / events / functions / activities that occur.
In connection with the second indicator, namely the structure of the vision of patterns,
relationships between objects, and inter-subject-object, further Lynch (1991) reveals that
there are five elements to reveal the image of the city, namely the path, edge, district
(area), node, and landmark.
C. PROBLEM IDENTIFICATION
In order to facilitate assessment in the area,
then the object of study is divided into
neighborhood units, as shown in the picture on

River Cikapundung defined as urban catalyst in the planning area, with a turn on green space
and planned as a core activity areas with functions of recreation and tourism under the theme
of culture and environment. The development of this area is associated with the development
of commercial areas that are expected to spur growth in the region behind the commercial
area. The function of this urban area as a center of activity directed environment and culture
that is strengthened by the character of the village settlements.
The concept of macro-region arrangement is done by Urban Catalyst Concept which is
expected to further turn the region planning. In the area of Tamansari-Cihampelas, one way
to improve the quality of the Cikapundung River is restructuring the river bank to restore the
lingkage areas and open space.
The face of the residential community which is overlooking the Cikapundung River become a
pedestrian circulation path, and part of Cikapundung River become more organized with a
regular border with residential zone. Supporting the pedestrian path at the front of the
dwelling then began to grow micro-scale commercial functions that serve the community and
tourist who walk there. So this could be of economic value for the region.
