Abstrak: Rainfall-discharge transformation in a watershed is an indicator that shows the capability of watershed to control water yield and flood. During 2007-2012, in the region of Jakarta and Bogor show that the rainfall transformation into runoff in Ciliwung watershed including upper watershed in Ciliwung remains high. Knowledge about rainfall transformation in Ciliwung upper watershed are needed. Hydrological models are possible to estimate that rainfall transformation. One of the models that currently often be used is SWAT (Soil Water Assessment Tools) model. The prediction of discharge with SWAT model in Ciliwung upper watershed has satisfying result with coefficient of determination (R2) 0.53 and NSE 0.73. Landuse changes from 2009 to 2012 has decreased the coefficient of measured runoff from 0.76 into 0.22 and based on the estimated runoff has decreased from 0.9 into 0.7. Based on the best scenario of the landuse changes is to apply soil and water conservation in agricultural land with contoured tillage and improving mixed agriculture with agroforestry system, rainfall – runoff transformation runoff decreased from 1763 mm/year into 1565.2 mm/year and the discharge decrease from 4367.0 mm/year into 4350.9 mm/year.

Abstrak: Large floods that occurred in the Jakarta in 1996, 2002, 2007 and 2013 respect of Ciliwung watershed. Factors that cause flooding are basically two things that rainfall and land cover. The aim of study to analysis of frequency to predict the opportunity of maximum rainfall in one day, 2 days, and 3 days, as well as to analyze the maximum daily discharge in the return period of 5, 10, 25 and 50 years and to analysis change of land cover in Ciliwung up stream. The analysis result shows that the maximum rainfall in the period of 5, 10, 25 and 50 years are respectively 130 mm, 160 mm, 200 mm and 229 mm/day. While the opportunity of 2 day-maximum rainfall in the same return periods are 168 mm, 202 mm, 248 mm, and 283 mm respectively. The opportunity of 3 day maximum rainfall in the same return periods are 215 mm, 268 mm, 337 mm, and 389 mm respectively. The opportunity of maximum daily discharge in the return periods of 5, 10, 25 and 50 years are 470 m3/s; 565,5 m3/s; 703,4 m3/s, and 819,5 m3/s respectively. The minimum daily discharge in the same return periods are 1,4 m3/s; 1 m3/s; 0,7 m3/s; and 0,6 m3/s respectively.The average increase in the area woke up from 1996 to 2011 was 71.8 ha/year.

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.
