Abstract

Flooding that occurred in the Makassar City is 23 % of the total area of the city, that is 4086 ha. This floodwaters research is focused on Tamalanrea districts, which constitute the largest districts hit by floods about approximately 1684.59 ha. The spot selected region is BTN Hamzy, Antara ,and Asal Mula Housing. Flooding that occurred in this region is caused by changes in land use, poor drainage, sloping contours and form a basin area, and impermeable soil so that runoff contributes high . High rainfall can also cause floodwaters at this location. An understanding of the process and the amount of runoff and the influenced factors are very necessary as a reference in dealing with flood control. The purpose of this study was to determine the rate of surface runoff, extensive flooding, and flood inundation predictions, the effect of changes in rainfall intensity on surface runoff. Analysis procedure is conducted to calculate the rate of runoff using USSCS 1973 rational methods with variables: land cover, soil type, and slope contour, area, and intensity of rainfall. The results of these calculations are compared with the volume of land each contour and intensity of rain to predict floodwaters and the effect of rainfall intensity on surface runoff.

Abstract

The existence of minimarket as the one of consumer goods retail activities around settlement residents needs to be considered, especially in its spread and radius service. It isoutlined in the SNI No. 03 Tahun 2004 about “Tata Cara Perencanaan Lingkungan Perumahan di Perkotaan” that is for the grocery store/stall (minimarket) can serve 250 people with 300 meters radius achievement. There are 15 minimarkets (2013) that lie at Bumi Tamalanrea Permai settlement and Telkomas Housing in Makassar City, it’s radius is not appropriate with standard and also don’t concern with traditional consumer goods. The main focus in this research are analyze the consumer goods retail typologyand correlation levelbetween the variablesinelection of retail locations. Descriptive and Map Overlay (GIS) analysis explain the consumer good retail typology that consists of 3, modern minimarket, semi minimarket, and stall. Correlation analysis explains the correlation levelbetween the variables inelection of retail locations, age, walking distance, income, hospitality services, and minimarket location are very significant. Based on that results, it will be required the appropriate idea of the consumer goods retail spreading so that prevalent radius service will take place.

Abstract

The existence of public services is a strong factor in development area centrifugally. One type of public services in Makassar Periphery Area is Hasanuddin University Educational District. Development of large district of education will be followed by increasing of resident and activity support amount that influence the developing built-up area. Development of the built-up area was analyzed by spatially, descriptive and binary regression methods. Factors affecting the development of the built-up area were the presence of attractive elements such as campus, infrastructure and facilities, strategic location, and the cheap land prices. The growth forms of the built-up area are grid and linear pattern with some buildings used for housing, government facilities, office facilities and educational facilities. Linear pattern lies through the street fanced by the buildings used as trade and service facilities. The impacts of built-up area development are the increasing of building density, kindship society, land value and building’s physical condition.
