Judul: Optimalisasi kondisi fisiologis puyuh Jepang (Coturnix coturnix japonica) dengan suplementasi serbuk kunyit (Curcuma longa)
Abstrak: Quail have an economic value. Egg production decreased as the decline of the quail’s physiological conditions, either due to aging or stress. The purpose of this study was to optimize the physiological condition of quail with turmeric powder supplementation. The study was conducted in four stages: 1. Determining the physiological deterioration quail, 2. Getting the optimal dose of turmeric powder to improve quail physiological conditions, 3. Knowing the profile of reproductive hormones in an ovulation cycle, 4. Determining the effect of turmeric powder at different times and types of feed on Japanese quail. The decline in quail’s liver function occurs after the age of 7-8 months as evidenced by a decrease in body weight, percentage of liver weight / body weight, hepatocytes diameter, ovarium and reproductive tracts weight, as well as an increase in the levels of SGPT and SGOT serum.Turmeric powder at a dose of 54 mg / quail / day may improve liver function. Curcumin in the content of turmeric powder at 7.97% has a hepatoprotective effect, which was supported by the percentage increase in liver weight / body weight, DNA content of the liver, hepatocytes diameter, and decrease in SGPT and SGOT levels, triglycerides, and blood cholesterol. Content of phytoestrogens in turmeric powder at 6.73% was able to induce increased synthesis vitellogenin as yolk precursor, so vitellogenin levels in the blood rise. Most vitellogenin stored in hepatocytes was indicated by the number of vacuoles in the cytoplasm of hepatocytes. Vitellogenin mainly distributed to the ovarian follicle to the development hierarchy. The number of growing follicles may accelerate follicular maturation, as evidenced by the shortening of the cycle time of ovulation approximately 5 hours 35 minutes, and an increase in the number of eggs. The number of follicles was ovulated that can spur the growth of the glandular cells of the reproductive tract to secrete albumen, shell membranes, and eggshell. Turmeric powder is also able to increase the absorption of calcium, so it can improve the quality of the eggs. The number of growing follicles also contributes to improving egg quality which evidenced by the decrease in cholesterol and fat eggs. This is due to the growing number of follicles, fat, and cholesterol will be distributed to many follicles. Provision of turmeric powder was most effective when given before maturity sexual. Giving turmeric may extend quail’s productivity. Feeding the higher protein did not able to increase the productivity of quail.

Judul: Performa produksi burung puyuh (Coturnix-coturnix japonica) yang diberi pakan dengan suplementasi omega-3
Abstrak: Supplementation of Omega-3 in ration may enhance Omega-3 and lower the cholesterol contents in quail eggs. However, its impact to productive performances has not been clearly proved. This current experiment aimed to study the influence of Omega-3 supplementation in ration on productive performances of Japanese quail (Coturnix-coturnix japonica). This study was carried out for two months in the field laboratory of Poultry Production and Technology, Faculty of Animal Science, Bogor Agricultural University. This study involved 298 Japanese quail age 10 weeks and designed completely randomized in 5 treatments with 4 replications. The applied treatments were Omega-3 supplementation in the ration: P1 (control), P2 (1.5% Omega-3), P3 (3% Omega-3), P4 (4.5% Omega-3), and P5 (6% Omega-3). The observed traits were feed consumption, egg production, egg weight, feed conversion, mortality, and index of quail egg. All data were collected and descriptively analyzed. This study revealed no influence of Omega-3 supplementation to the production performance and index of quail egg.

Judul: Identifikasi Kejadian Banjir Rob (Pasang) di DAS Sunter pada 9-13 Januari 2008.
Abstrak: Banjir Rob merupakan fenomena meluapnya air laut ke daratan, istilah tersebut pertama kali dikenal di daerah Semarang. Fenomena banjir Rob dipengaruhi oleh pasang surut air laut. Pasang surut sendiri dipengaruhi gravitasi bulan dan matahari, serta dipengaruhi pula posisi bulan dan matahari terhadap bumi. Banjir ini biasa terjadi pada saat pasang air laut yaitu bertepatan dengan kejadian bulan baru dan bulan purnama. Pada bulan Januari 2008, di wilayah utara Jakarta yang berbatasan dengan laut, fenomena banjir Rob (pasang) melanda kawasan tersebut. Fenomena ini mengakibatkan sejumlah kawasan di wilayah utara Jakarta terendam air laut, hal ini diperburuk dengan penurunan muka tanah Jakarta. Selain dilanda banjir pasang air laut, kawasan utara Jakarta sering dilanda banjir akibat luapan sungai-sungai yang bermuara di Jakarta, salah satu sungai yang menyumbang banjir Jakarta adalah sungai Sunter. Tutupan lahan di DAS Sunter yang sebagian besar berupa pemukiman makin meningkatkan limpasan permukaan ketika terjadi hujan. Tanggal 9-13 Januari 2008 di perairan Teluk Jakarta sedang terjadi pasang air laut karena bertepatan dengan bulan baru yang mengakibatkan terjadinya banjir Rob di beberapa wilayah di Jakarta Utara, termasuk DAS Sunter. Berdasarkan pemetaan banjir Rob di DAS Sunter pada tanggal 9-13 Januari 2008 diketahui bahwa daerah yang tergenang air laut yaitu Kalibaru dan Marunda dengan tinggi genangan 48-72 cm. Luas genangan maksimum terjadi pada tanggal 11 Januari 2008 yaitu sebesar 66.000 m2. Pada tanggal 9-13 Januari, DAS Sunter tidak ikut menyumbangkan limpasan permukaan yang dapat menyebabkan banjir karena nilai limpasan permukaan berkisar 0-3,03 mm. Sehingga kejadian banjir pada tanggal 9-13 Januari 2008 di DAS Sunter hanya berasal dari pasang air laut. Kata Kunci : Banjir Rob, Pasang-Surut, Limpasan Permukaan, DAS Sunter.
