SHAPING URBAN SPATIAL STRUCTURE INDONESIA
SHAPING URBAN SPATIAL STRUCTURE
From Policy to Energy Consumption
by : Beta Paramita 1
Cities in Asian countries have many similarities in regard to its form and shape, especially in the
south-east Asian regions. The history of the city trace back along the transportation stripe (mainly
rivers) with its linear character. Singapore, Indonesia, Malaysia, Thailand, Vietnam, Cambodian, and
Philippine were have a main river in their major cities respectively. Water was become the main
reason for some people to build their houses along the river.
It is interesting to discuss the urban spatial structure since cities growth patterns are undergoing
quantitative and qualitative change. For the last two centuries, cities have been sprawling out, then
the process of decentralization has taken a more polycentric form, with a number of concentrated
employment centers making their mark on both employment and population distribution. 2Indonesia with around 240 million people inhabitant, as the 4th populous country in the world is facing
demography’s problem on an urban spatial structure associated with the population growth, such as
land use, water supply, equipping settlement and its facilities.
This paper will describe the correlation between the spread of the city growth, urban spatial structure,
spatial policies and regulations and then finally the urban energy consumption. Overcrowded
residential areas along Cikapundung River in the middle of Bandung City will be taken as a case
study.

A. Introduction
1. Urban Structure
Urban structure was established as the result of complex sources, such as: history, economy,
politic as well as its unique character of urban geomorphology. Gradually, all of these aspects will
create some demographic problems of the city like overcrowded population, needs of land,
limited access to clean water, bad sanitation and city infrastructures as well as lack of public
spaces, including green open space. The physical aspect of urban structure is the urban form,
and it is closely related to scale and has been described as the ‘morphological attributes of an
urban area at all scales. (Williams et al., 2000) 2
Urban form 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.3

Density, will be the most crucial elements of urban form, such as land use and access to
services – for example, for a service or facility to be viable, it needs to serve a population of a
particular size. Density, on the one hand, can be seen as an outcome of the competition
between land uses within a given urban transport infrastructure and its associated pattern of
accessibility. On the other hand, it is a policy goal as it is also an input into the quality of
urban life through the viability of services provision and availability of public and private
space. Density has therefore been used as a tool to measure the viability of public transport
infrastructure and other service provision, the feasibility of certain land uses, particularly
commercial and service, in urban design and construction. At what point density becomes
high (or too high) is unclear, but in recent years planning policy and practices in many
countries have been attempting to increase the average density of new development.
Thus, this paper tries to describe the relationship between urban form and sustainable
development, which have a strong effect to energy use. In particular, it outlines a typology of
city forms. The three main archetypal urban forms discussed are: the linear city; the city set
out in the form of a grid; and the highly centralized or inward-looking city. The regularities and
irregularities of urban structure on this paper will be described by using land-use in 2009 of
Bandung City, and it will be explained in the degree of spatial concentration of urban
population and the form of town. The research concentrates on the physical design of urban
form with respect to: physical configuration and layout, including links to the wider urban
system; its land uses and functions; the typology and density of built form.
2. Urban Settlement in Bandung
Bandung is mention as the most attractive city in Indonesia, this city as never sleep. The
distance from Jakarta is about the 128km or 3hours trip. It made Bandung as backyard of
Jakarta citizen. The population of Bandung City is 2.329.928 persons, which determines the
growth rate 1,88%. The average of population density in Bandung City is 13.927,48
pr/sq. This density is not including the commuters from a periphery who work to Bandung in
a day, and there will be around 3 million in Bandung in working hours. The limited land and
the high demand of land then made Bandung is facing the demographic problem associated
with the population growth, such as land use, water supply, equipping settlement and its
facilities.

In 2000, land use for settlement has already occupied 53% of total land use, which is
8.866.715 ha and accommodate for 2.136.260 inhabitant of Bandung citizen. In 2013, the
planning of land use for settlement already set maximum 60% of total Bandung’s land, which
is 10.037. 790ha and prepared to accommodate for 2.944.860 inhabitant. The land's rest is
counted as 1.171.075ha, which is very limited land compare to the inhabitant who is needed
to be settled, the other problem that may have to face is the spread of the inhabitant in
Bandung wasn’t in the same amount and condition. The dense district is Bojongloa Kaler
with 39.240pd/km2 and the lowest dense district is Arcamanik with 782.5pd/km2. The limited
land then became the most problem in Bandung in supplying house demand, with the
population increasing from year to year. It's become urgent matters to be addressed.
The number of urbanization, limited subsidized house, uncontrolled birth and the other
helplessness of demography’s problem are such a classic problem in big city-like Bandung,
its force incompetent citizens to supply their demands as their own ways and the other hand
infirmness of the legal aspects could not clearly be operated. The urban structure of Bandung
now, is the result of stack of the land use problem, which create the dense and tend to slum
area.
B. Urban Structure as The Result of Historical and Political Will
The layouts of today’s cities are largely
1
artifacts of their historical development and
planning and building regulations. The
configuration of the street network, in terms
of its urban block sizes, their overall
location within the city, pedestrian and
vehicular
connectivity,
can
affect
the
functioning of a city by, for example,
influencing the location intensity of activities
(Penn et al., 1998; Porta et al., 2008).
1. Density and Land-use
As one element of urban form of the most
influential in shaping the structure of the city,
it is necessary to set out the measurement
and assessment of the density of a city.
See population density of Bandung at
Table 1.
Recent moves towards the creation of more sustainable towns and cities that offer a high
quality of life whilst minimizing resource consumption (such as energy, land and water), have
reawakened interest in the concept of density. The benefits of seeking higher-density levels
in overall terms are well recognized especially in the context of delivering mixed-use
development where a minimum housing density is required to sustain non-residential uses.

It should be shaping the mass of built form to frame positive, but unfortunately somehow in
the
high
dense
area,
this
artifact
resulting
in
negative
scenery
of
a
city.
In contrast, much recent development, which may have exactly the same population density
of its traditional counterpart, is characterized by flat, featureless density profiles. This is the
product of building down to imposed standards or density levels, such as 25-30 dwellings or
150 - 200 habitable rooms per hectare. Built form is distributed and density bumps ironed out.
2. Slum, an Excess of Density
Density is a measure. How comfortable a place feels is a matter of the design and its social
characteristics. Somehow, overcrowded is closely to slum area, since the high needs of a
land and infrastructure requirements which is often neglected by local government also the
growth rate of building that do not meet the rule of building regulation. That condition then
shows in the urban spatial structure as an unplanned area. The density of population and
building should be equilibrated with the equipping of infrastructure, if there is no powerful
policy to settle down the accretion of building or the urban sprawl, so that would be crashed
with urban land use and also give impact to urban form, which is finally set up the urban
structure irregularly and could be said as a slum area.
The definition of slum area by UN Habitat: slum is an area that combines to various extents
the following characteristics, such as :
a. Inadequate access to safe water
b. Inadequate access to sanitation and other infrastructure
c.
Poor structural quality of housing
d. Overcrowding
e. Insecure residential statue
In Indonesia, slum area is defined by 6(six) criteria, which are: 5
a. Vitality area in non economic aspect (congruity with urban planning, physical condition of
building, demographic condition)
b. Vitality of economic aspect (existence to the surrounding, distance to activity, function of
surrounding area)
c.
5
Land statue (domination of legal aspect, domination of ownership of land)

d. Infrastructure (street, drainage, water service, sewage, solid waste)
e. Government commitment ( institutional, fund)
f.
Priority of handling the problem (management plans, physical improvement)
From the criteria above, urban form of Bandung will be accessed to measure the physical
quality and to classify area (district) as an urban artifact. The density tend to slum, if the
building in 1ha more than 100unit, and habitable room more than 25unit/ha. To assess the
dense area as a slum area, it is made a typology of housing which is divided into 3 typologies
with their characteristics, and shown in table 2.

C. Environment and Energy Implication
The negative effects from the inner to the use of energy and its impact on the environment and
energy consumption still requires further research, but at least here can be described in general, the
impacts that occur every day in the slums
The lack of open space in the slum area, give a complex impact to many aspects, such as:
1.
The availability of daylight, which means people in this area, live in the dark and the demands of
electricity much greater
2.
The high of temperature and also humidity inside the house force them to use fan to make the
better air circulation. Bandung is tropical city, so the highest temperature (day) is average
32ºC
and the lowest (night) 19ºC and the humidity reach between 70-90%.
3.
The limitation of area of infrastructure placement made the absence of sewerage lines, either
overflow of rain water, dirty water from house, in some case all this liquid waste is directly pour to
river.
4.
No access for waste transport vehicle, accumulate of solid waste. In some river bank settlement,
the solid waste discharged into the river whereas the river is a source of clean and drinking water
for Bandung. Beside for clean and drinking water, Cikapundung River is one of river which is
supplying for hydroelectric-power, which is downstream to Citarum River. There are three
hydroelectric-power using water discharge Citarum watershed as its supply, i.e. hydroelectric-
power Ir H. Juanda (Jatiluhur), Hydroelectric-power Saguling, and hydroelectric-power Cirata.
Hydroelectric-power plant supplying electricity to the island of Java, Madura, and Bali.
Calculations obtained from the three hydropower in Citarum river flow was produced energy
equivalent fuel oil by 16 million tons / year
5.
No space for social activity, this is bad for children because they lost their space for playing, and
also people live here sometimes neglected between private or public space
Some of urban structure problem in slum area could be seen as figure below :

The negative effects from the inner to the use of energy and its impact on the environment and
energy consumption still requires further research, but at least here can be described in general, the
impacts that occur every day in the slums
The lack of open space in the slum area, give a complex impact to many aspects, such as:
1.
The availability of daylight, which means people in this area, live in the dark and the demands of
electricity much greater
2.
The high of temperature and also humidity inside the house force them to use fan to make the
better air circulation. Bandung is tropical city, so the highest temperature (day) is average
32ºC
and the lowest (night) 19ºC and the humidity reach between 70-90%.
3.
The limitation of area of infrastructure placement made the absence of sewerage lines, either
overflow of rain water, dirty water from house, in some case all this liquid waste is directly pour to
river.
4.
No access for waste transport vehicle, accumulate of solid waste. In some river bank settlement,
the solid waste discharged into the river whereas the river is a source of clean and drinking water
for Bandung. Beside for clean and drinking water, Cikapundung River is one of river which is
supplying for hydroelectric-power, which is downstream to Citarum River. There are three
hydroelectric-power using water discharge Citarum watershed as its supply, i.e. hydroelectric-
power Ir H. Juanda (Jatiluhur), Hydroelectric-power Saguling, and hydroelectric-power Cirata.
Hydroelectric-power plant supplying electricity to the island of Java, Madura, and Bali.
Calculations obtained from the three hydropower in Citarum river flow was produced energy
equivalent fuel oil by 16 million tons / year
5.
No space for social activity, this is bad for children because they lost their space for playing, and
also people live here sometimes neglected between private or public space
Some of urban structure problem in slum area could be seen as figure below :
