Judul: Analisis Hidrologi Bendung Katulampa: Potensi Pengembangannya sebagai Bendungan Pengendali Banjir Jakarta
Abstrak: As Jakarta developed into a metropolitan city, flood problems become the center of attention for its citizens and government. Ciliwung river is one of significant contributors to flood discharge in Jakarta. Flood control can be done by constructing a dam which retains water in the upstream area. Katulampa weir is often taken as indicator and early warning for Jakarta’s flood eventhough it’s not a flood control structure. Hydrological analysis taken as an initial step to understand the potential of Katulampa weir to be developed as a dam. Twenty three years daily rainfall data from three stations are analysed using log Pearson III (LPIII) distribution to produce design storm with 25, 50, 100, and 200 years of return periods. HEC-HMS (Hydrologic Engineering Center-Hydrology Modelling System) was employed to model design flood using two storm events in two different days. It resulted design flood with average of 91.2; 107.5; 124.6; and 142.5 m3/s also total inflow flood design volume 3.4; 3.9; 4.5; and 5.1 million m3 for each respective return period. A simple simulation was performed to estimate inundated area in Katulampa as dam. It turns out that 35-45 ha are needed to retain flood volume per return periods above.

Judul: Analisis Debit Puncak dan Aliran Permukaan DAS Ciliwung Hulu pada Bulan Januari 2014 (Studi Kasus: Bendung Katulampa)
Abstrak: Upper Cilliwung Watershed closely related to Jakarta flooding event. Water level in Katulampa dam reached 230 cm equal to discharge of 552 m3/second on 29 January 2014. It presumably because of countinuous rainfall all day with the intensity from low to high. The rain that continuously fell for few days caused the soil saturated so that the number of surface flow significant increased. The relation between the rainfalls in three observation stations which are Citeko, Gunung Mas, and Katulampa as well as average rainfalls and the discharge on Katulampa dam showed a correlation values of 0.87, 0.87, 0.83, and 0.87 respectively. It explains that rainfalls on three observation stations as well as average rainfalls affects the water level on Katulampa dam. The higher the rainfall in Upper Ciliwung Watershed, the higher the water level on Katulampa dam will be. The coefficient value of the surface flow on 12, 17, 21, and 29 of January 2014 are 20.7 %, 32.8 %, 37.7 %, and 33.8 % respectively.

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).
