Abstrak: Limitations of observational data are often a hindrance in the analysis of the flood. So it is necessary to other data that can represent data of observation, namely the utilization of remote sensing data TRMM (Tropical Rainfall Measuring Mission) belongs to Japan. TRMM data was designed to meet the global rainfall data in the tropics.. The purpose of this study is to develop a simple regression to estimate the Ciliwung river discharge (Katulampa and Depok) using rainfall data from TRMM satellite. TRMM data were validated with observational ground station rainfall data with regression techniques and contingency table by looking at the possibility of detecting occurrences of rain and no rain. The results of the regression between rainfall of TRMM and precipitation station were Gunung Mas Rainfallobservation=0,978×RainfallTRMM+48,18(r=0,79), Katulampa Rainfallobservation=0,929×RainfallTRMM+130,70(r=0,75), and Depok Rainfallobservation=0,468×RainfallTRMM+65,57 (r=0,47). Based on the contingency table techniques, Katulampa station have the highest accuracy. Judging from the two trials can be said that the TRMM rainfall data has been able to represent data observation stations. Results of linear regression equation between the discharge Q (m3/s) from TRMM rainfall (mm / month) for both stations are Katulampa: Q = 0,017 * R +3,603 and Depok: Q = 0,039 * R +7,758. Lowest error is owned by Katulampa station (r = 0,56) is 4,343(r=0,(r=0, (r=0,4.

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: 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.
