Urban development leds to negative consequences on several aspects, including environmental aspects. In the early stages of urban development, most of the land is green open space (green space). However, there is space to accommodate the needs of the population and activities; green space tends to conversion of land into the region in order to construct the buildings. Most of its surface, especially in the city center, covered by roads, buildings and others with characters that are complex and vary with the character of open spaces. Therefore, the study of urban planning should be analyzed from the point of view, one of them in terms of the environment. In this study reviewed the distribution of Banjarbaru green space green space in terms of the ideal ratio of Instruction of Minister of the Interior No. 14 of 1988 to the total area and population.
