The presence of slums tend to grow on, in line with the rapid rate of population growth. To meet the demand for housing, they can only build homes in places that match the power and ability (low-income communities). They occupy settlements on lands not reserved for residential areas such as the former Graveyard, behind the barn or the mall, building walls against the property of others, along the Embankment or flood plains, and so on. They are not able to buy land or a house suitable for Habitation,  so they invaded the vacant land that allows them to build huts with cheap building materials and waste affordable. They can only build shacks made of secondhand goods (rest / waste) such as zinc scraps, cardboard, pieces of wood, bamboo and so worn, the location of empty and no man's land in the corner of the city, without attention to the rules of the city (master plan), because they also would not know the rules of the city or they do not want to know about the rules. Condition of infrastructure and basic facilities of housing and settlements would not be available, if there would be so minimal, that is not unusual for the environment they occupy creates slums (slums areas).

The area is a unified whole, to cultivate resources and funds to manage the existing environment to support the continuation and improvement of the quality of human life. In addition, also provide security, peace, pleasure, comfort and peace, in harmony, harmony and balance to function as a container that can serve your personal life, family and community.
