Abstrak: Ciliwung upstream watershed region has functions as a protector area and also buffer area of the watershed. At present there are many land function changing on the Ciliwung watershed that effecting the river overflow easly until flooding in the downstream. River discharge assessment become important to do in order to prevent flooding. ArcSWAT software is a tool which used in this discharge assessment. ArcSWAT software have 4 processes to do, that are watershed delineation, shaping of Hydrological Response Unit (HRU), shaping of climate data, and also simulation process. Simulation yield for the upperstream of Ciliwung watershed has shaped 27 sub-basin and also 491 kind of HRU. This research utilize SWAT Editor as the application for the calibration. Base on simulation yield calibrated, maximum monthly discharge has been obtained as big as 59.42 m3/sec, minimum discharge as big as 2.02 m3/sec, and also average discharge as big as 14.61 m3/sec. Coefficient determination value of R2 and NS value are 0.831 and 0.599. For this result the simulation yield of ArcSWAT for Ciliwung upperstream watershed is valid with the good category result.

Abstrak: Management of the upstream watershed was significant factor because it had a role as the water catchment area to decrease the surface flow and potential flood. Ciliwung watershed had been gaining attention because the Indonesia central government, which is Jakarta, was located in the downstream of that watershed frequently flooded. The Ciawi Reservoir construction program on the upstream watershed was expected could help to recover that issue. The aim of this research was to analyse the effectiveness of Ciawi Reservoir by hydrology response that obtained by apply the SWAT model. The scenario of reservoir modelling was made on the hydrology simulation that had been formed, so the alteration of hydrology response that happened before and after the reservoir model applied could be known. There were 28 subbasins and 516 HRUs with 9 types of landuse, 3 soil types, and 5 slope classes on Sub Ciliwung Hulu watershed. The reservoir modelling with 15 scenarios indicated the alteration of flow discharge that specifically observed on outlet point 1 (Katulampa). The highest total discharge derivation was 158.626 m3 s-1 (34%), while the highest peak discharge derivation was 27.07 m3 s-1 (47.79%), and the best KRS value was 28.326 with good category. Based on the obtained result, the scenario of reservoir modelling managed to minimize the flow rate, so it could be said that the construction of Ciawi Reservoir was considered effective enough.

Abstrak: Telur merupakan salah satu bahan makanan asal ternak unggas yang kaya akan gizi, seperti karbohidrat, protein, lemak, vitamin dan mineral, disamping harganya murah, sehingga disebut wonderful food. Oleh karena itu, tidak mengherankan konsumsi telur di Indonesia cukup tinggi dibandingkan dengan bahan makanan sumber protein hewani lain. Disisi lain, adanya persepsi, bahwa sebutir telur mengandung kolesterol relatif cukup tinggi, yaitu 200 - 250 mg atau 1280 mg per 100 g kuning telur (yolk).
