Penentuan Lokasi, Luas, dan Volume Genangan Air Sebagai Potensi Cadangan Airtanah di Perumahan Tamansari Persada, Bogor

Abstract

The changes of the green land-use as retention area to become housing area, will cause problems like enhancement of run-off, reduction of water infiltration to the land, as well as puddle and flood if water volume increases in some area. A study was conducted with the objective to determine the location, area, and volume of puddles at Tamansari Persada Residential, Bogor as groundwaters storages potential. The procedure of sampling and analysis of the data were determination of fixed location of puddles, determination of coordinate points for area and volume of puddles, and analysis of the data by aSurfer 8’s software and Gridding Krigging Method. According the research result from March to April 2013, there were three fixed puddles locations at Palm Cluster and routine flood occured when rain was falling and the maximum volume and area puddles for the first location were 0.11 m3 and 6.57 m2, the second location were 0.26 m3 and 18.82 m2, and the third location were 0.35 m3 and 20.77 m2. Generally, there are correlation from enhancement of lowest elevation, areas, and volumes of puddle and have been proved by Linear Regresion Method. From this method will produced puddle potential formula and the value of determination coefficient (R2) closer to 1. The location, areas, and volume of puddles could becoming reference of puddles potential and absorbed to the ground as an groundwater.
