ABSTRACT
Making a health living environment in a city is a challenge for city planners. This study Was conducted to collect the data of slum settlement problems in Medan City of Indonesia.
A survey method was applied to seek the data of slum settlements. It was noted that out of
40% of the low-income population, 4.28% of households live in uninhabitable urban Environments and 15.52% of households live in uninhabitable rural environments.
Data Showed that the most rapid increase in population density in the past year is in the areas of Medan Helvetia (110.32 people/km2), Medan Amplas (143.27 people/km2) and Medan Timur (72.65 people/km2). These three areas have a great opportunity to generate some Illegal settlements and make them slum areas. As a result, it makes the Medan City could not provide the inadequate infrastructure due to the rising number of people living in slum settlements. It concludes that the City of Medan has been dealing with the problem of slum and squatter settlements.

ABSTRACT
Traffic congestion needs a simulation model to reduce its effects on traffics jams and pollution. The traffic cessation caused by the large number of vehicles exceeding the capacity of the road users. This study applied a stochastic program to the traffic congestion; it causes most of the working hours to be spent on roads that indirectly place a negative impact on economic growth. It also causes serious air pollution that will worsen the overall environmental condition. Data obtained show the factors causing traffic congestion in the city of Medan and with approach the stochastic program model used to solve this problem. Data indicated that there are four factors causing traffic congestion in Medan, which are non-growth of road, economic growth, population growth, and increase of motor vehicle.Population factor; the existence of good population growth caused by natural and migration growth. It concludes that the traffic jams are due to the socio-economic factors; namely the development of community business activities. Also socio-cultural factors; the existence of changes in the pattern of life and public order due to outside influences, communication, and information systems.
