Abstract
The infiltration capacity will decrease if the number of infiltration fields decreases. This results in increased surface runoff or inundation. The planning concept that creates a groundwater infiltration area in drainage will be able to reduce inundation in drainage. Pore Cylinder Hole is a water infiltration method by increasing water absorption in the soil. The aim of the study was to determine the effect of pore-hole spacing on infiltration capacity in pore-cylindrical drainage and to determine how much infiltration discharge due to variations in hole spacing using three levels of pore cylinder heights. This research was conducted using a pore-cylindrical drainage model and spacing the biopore holes and flowing water on the drainage surface. From the results of this study, it was found that the effect of the hole distance on the infiltration discharge, the closer the hole to the pore cylinder, the greater the infiltration discharge that occurs, it can be proven from the results of analysis of research data, for a flow rate of 400 cm3/sec, Qf = 35.1 cm3/sec. for spacing of holes 16 cm); Qf = 31.9cm3/s (to describe 32 cm holes); and Qf = 3.13cm3/s (for spacing of 16 cm holes).

Sketch of Pore-cylinder Drainage Channel Model. This model consists of two containers, namely the one block model container which functions as a water storage container and the second block container which functions as a soil storage container made of acrylic
The amount of debit passing through the Thomson door is calculated by the formula: Q=
Summary
The increase in population is accompanied by further development in the city of Makassar. Development that is not evenly distributed and not environmentally sound results in loss of catchment areas and flooding during the rainy season. Construction of drainage that is not environmentally sound is a major factor in flooding. Drainage plays an important role in regulating water supply for flood prevention. Drainage means flowing, draining, disposing, or diverting water. Drainage is defined as a series of water structures that function to reduce and / or remove excess water from an area or land, land can be used optimally [15]. Drainage is defined as an attempt to control the quality of groundwater in relation to sanitation [15]
