Abstrak: Negative impact due to the disappearence of water catchment is the decrease of land capability to infiltrate rainwater causing run off, ponding water or even flooding. This research was conducted with anobjective to know a relationship between rainfall and volume of the ponding water. The location selected in this research was Tamansari Persada Residence in Bogor between March until April 2013. The research was conducted in two phases, which were primary data collection by measuring coordinate points of the ponding water and secondary data collection of daily rainfall. Gridding method based on Surfer 8 was used to calculate the volume. The results showed linear equation relationships between rainfall and volume of ponding water at Location 1 is y = 14.80x - 1.456 with the coefficient of determination 0.558, in Location 2 is y = 30.56x + 96.18, with the coefficient of determination 0.901, and Location 3 linear is y = 53.16x + 46.89, with the coefficient of determination 0.685. The small coefficient of determinations at Locations 1 and Location 3 might be caused by several factors such as ineffective use of time measurement.

Abstrak: 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.

Abstrak: Egg is an animal origin food product which has high nutritional value especially protein. Cholesterol content of eggs is only found in egg yolk, on the other hand albumen does not countain cholesterol at all but high content of protein, so it can be used as a free cholesterol-protein sources. The application of albumen as egg instant drink effervescent tablet can be an alternative of protein source for people who need free-cholesterol diet. It can also become an egg product diversification.
