Judul: Aplikasi Model IFAS Untuk Membandingkan Debit dari Tiga DAS (Studi Kasus: Kabupaten Boyolali dan Klaten Jawa Tengah).
Abstrak: River discharges influenced by watershed characteristics and nature of precipitation that falls within the catchment area. The amount of discharge can be calculated from measurements or estimated using a hydrological model. Various hydrological models can be used to analyze the discharge of a river. One model that can be used is IFAS (Integrated Flood Analysis System). In this study, the IFAS model is used to estimate discharge from upper Gandul, upper Pusur, upper Soka and downstream Pusur, each with catchment areas of 29.8 km2, 10.7 km2, 22.7 km2 and 33.43 km2 respectively. The main inputs used in the model were rainfall, elevation data, land cover, watershed boundaries, and the coordinates of each watershed. IFAS model simulation results indicated that the largest of the three rivers flow upstream the river discharge was upper Gandul river which has a maximum daily discharge of 27 m3/sec while the lowest was upper Pusur river which has a maximum daily discharge of 7 m3/sec. Differences in discharge of the three rivers caused by morphometric characteristics of a watershed i.e: basin area, shape of watershed, river density, river slope, and also geological and pedological characteristics.

Judul: Analisis Debit Aliran Sungai Menggunakan Model SWAT di Sub DAS Ciasem Kabupaten Subang Jawa Barat
Abstrak: Increasing developed area and decreasing forest area lead to increase runoff coefficient that further to increase the stream discharge during rainy season and draught in dry season. The hydrological model can be applied to understand that phenomena. One of them is SWAT model. Application SWAT model in this research is focused only in rainfall transformation into discharge. Research is conducted in Ciasem Sub Watershed. The aim of this research is to know the dinamics of land use change and stream discharge in Ciasem Sub Watershed, also to know the effectiveness of SWAT Model for analyzing stream discharge by using available data in Ciasem Sub Watershed. The change of land use at 2003, 2006, and 2009 particularly happened on paddy field which was changed into a mixed agricultural dryland area of about 3253,8 ha, decreased runoff coefficient. Discharge estimation using SWAT model with measured rainfall at Curugagung Rain Station as input did not fit succesfully to measured discharge at Ciasem Sub Watershed outlet. Discharge estimation using SWAT model with simulated rainfall as input results better fitting to measured discharge at Ciasem Sub Watershed outlet with the value of R² > 0,51 and NS > 0,74. The result of the simulation showed that land use change of paddy filed to mixed agricultural dryland decreased runoff coefficient from 0,21 to 0,12 and also monthly maximum runoff discharge from 117,55 m3/s to 79,68 m3/s.

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).
