Recently, many distributed and "pliysically based" models wcrc dcvclo1)cd. AGNI'S is a coniputer sitnulatiori distributed model, developed to predict run-off volume, peak rate. erosion, delivered sediment, N, P and COD in the run-off for single stomi event at all cells in the waterslied. Corrclatio~i and pairecl test analyscs usiiiy 10 events pointed out that correlation between inodel output and nieasured peak rate gave the value of RZ = 0.3468 and no significant difference at 86.2 %. These analyses using 8 events gave the value of RZ = 0.9001 and no significatit difference at 98.7 %. Model output at initial wtldiGoii predicted erosion at Cigulung-Maribaya Sub-watershed over than maximum tolerable limit (30 Mgllia-year). Six land use sceiiari.os were si~iiulatcda rid used in AONI'S model in attempt to decrease flood, soil erosion, and sediinetitation.

Judul: Penggunaan model AGNPS berbasis sistem informasi geografis dalam analisis karakteristik hidrologi sub Das Ciawitali, Subang, Jawa Barat
Abstrak: Dalam pendugaan erosi, sedimentasi dan banjir diperlukan suatu metode prediksi dan pengukuran yang akurat dan terpercaya. Salah satu metode yang dapat digunakan adalah penggunaan model simulasi Agricultural Non-point Pollution Source (AGNPS) yang merupakan model terdistribusi dalam sel sehingga diharapkan mampu memberikan gambaran yang baik terhadap perubahan parameter-parameter yang disimulasikan seperti parameter tanah. topografi, tata guna lahan, dan pengelolaannya. Penggunaan model AGNPS dapat memanfaatkan SIG sebagai alat dalam menganalisis data spasial dan membangun parameter-parameter masukan yang digunakan dalam model AGNPS. Hasil keluaran Model AGNPS harus dapat di buktikan secara terpercaya melalui pembandingan hasil lapangan berupa pengukuran melalui SPAS. Penelitian ini dilakukan pada DAS Cipunagara yang memiliki sub DAS skala mikro (± 1000 Ha) yaitu sub DAS Ciawitali yang dapat mewakili daerah hulu.

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).
