Judul: Alih Ragam Hujan Menjadi Debit di Sub DAS Ciliwung Hulu
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.

Judul: Analisis Hidrologi di Sub DAS Ciliwung Hulu Menggunakan Model SWAT
Abstrak: The Ciliwung Watershed is one of the area which has a critical condition. It caused by residential increased in upper area. This condition change of hydrologic characteristics such as run off increased and flood risk. It means Ciliwung Watershed management must be improve. SWAT model can applied for watershed management scenario, such as predict run off and water balance. Model validation used daily data from 2001 to 2010 resulted the NSE 0.53 and R2 0.57, it means SWAT model is satisfy to predict hydrological conditions of the Upper Ciliwung Watershed. SWAT model shows by input annual rainfall 3 790.12 mm results run off 38.45% (1 457.38 mm/year), evapotranspiration 22.06% (836.04 mm/year), lateral flow 20.31% (769.92 mm/year), percolation 15.28% (579.02 mm/year), and ground water 3.90% (147.77 mm/year). Applied recharging well scenario at settlement area with the infiltration function similar with forest predict can reduce run off 46.17% (672.93 mm/year).

Judul: Enrichment of organic selenium, inorganic selenium and  vitamin E in quail products through its supplementation in the diet and its potency  of quail eggs as an ingredient in selenium-rich egg juice
Abstrak: This study was aimed to achieve an optimum level of combine organic selenium, inorganic selenium and vitamin E in obtaining the best production and reproduction as well as the highest level of selenium in quail eggs. This study was conducted from January to August 2008. Numbers of observed quails were 720 (360 females and 360 males). The treatments were applied when the quails were six weeks old. Nine treatment diets were: To (commercial diet), T1(0.46 ppm inorganic Se + 43.50 ppm vitamin E), T2 (0.46 ppm inorganic Se + 87.00 ppm vitamin E), T3 (0.92 ppm inorganic Se + 43.50 ppm vitamin E), T4 (0.92 ppm inorganic Se +87.00 ppm vitamin E), T5 (0.46 ppm organic Se + 43.50 ppm vitamin E), T6 (0.46 ppm organic Se + 87.00 ppm vitamin E), T7(0.92 ppm organic Se + 43.50 vitamin E) and T8(0.92 ppm organic Se + 87.00 ppm vitamin E).
