Judul: Karakteristik Lompatan Hidrolik pada Bangunan Terjun Tipe Ambang Lebar di Saluran Primer Ciliwung Katulampa III Bogor, Jawa Barat
Abstrak: Saluran Lnduk Ciliwung Katulampa mengalir sepanjang 31,500 meter mulai dari sumbernya yaitu Bendung Katulampa Bogor, Jawa Barat sampai pada batas wilayah DKI Jakarta. Saluran ini terbagi menjadi dua ranting yaitu Ranting Katulampa dan Ranting Cibinong. Pada Ranting Katulampa, saluran ini digunakan untuk mengairi lahan pertanian seluas 1493.6 hektar.

Judul: Kaji Ulang Parameter Hidrolika Bendung Cisokan Kabupaten Cianjur, Jawa Barat.
Abstrak: Bendung merupakan bangunan yang digunakan untuk menyadap aliran air sehingga muka air dapat dinaikkan hingga ketinggian tertentu. Penelitian ini bertujuan untuk menentukan dimensi hidrolika serta debit limpasan pada bendung dan saluran irigasi di Sungai Cisokan untuk dibandingkan dengan debit banjir sungai dan debit sungai selama bulan Maret 2017. Metode untuk menentukan dimensi bendung sesuai dengan KP-02 untuk bendung, dan KP-03 untuk saluran. Perhitungan elevasi mercu bendung diperoleh berdasarkan data elevasi muka air rencana pada bangunan paling hulu, kehilangan tinggi dari alat ukur, kehilangan tinggi energi pada intake, beda tinggi akibat sedimen, dan faktor keamanan. Elevasi muka air di hulu bendung dari hasil perhitungan berada pada 371,24 m. Lebar total bendung 54,5 m, sedangkan lebar efektif bendung yang telah dihitung sebelumnya sebesar 54,21 m. Bilangan froude hasil perhitungan sebesar 3,76 dan elevasi dekzerk terletak pada 373, 44 mdpl. Kapasitas bendung ditentukan berdasarkan parameter koefisien limpasan, lebar efektif bendung, dan tinggi energi maksimum. Dari hasil perhitungan diperoleh kapasitas bendung maksimum sebesar 112,10 m3/detik dan kapasitas saluran irigasi sebesar 10,15 m3/detik.

Judul: Physiological Status, Haematocrite, Blood Mineral Plasma in Sheep Infected with Gastrointestinal Nematodes and Offered 50% Concentrate.
Abstrak: Fourteen species of gastrointestinal nematodes may infect sheep and reduce their productivity. Haemonchur contorius is the main cause of anemia in sheep. with high prevalence level of about 80%. Commercial anthelmintic is expensive and its residue may create the problem. Evaluation of alternative methods to prevent infection of nematode is necessary. Nematode infection could be reduced by improvement of Feeding balance ration and early detection of early symptoms may reduce the intensity afnemalode infection. The present experiment was conducted to detennine physiological status. blood haematocrite and mineral Ca and Mg plasma of sheep infected by gastrointestinal nematodes and offered 50% concentrate with or without Zn supplementation. Thirty six of sheep having an average initial live weight of 12.06±1.7 kg were used in the present experiment. The sheep were grouped and allocated into three treatments: 8 sheep were in TO (control), 8 sheep were in TI (infected + 30 ppm Zn supplement), and 20 sheep were D (infected). Sheep were offered hay of Pennisetum purpureum and concentrate (50:50 dry matter basis) at rate of 4% oflive weight. Drinking water was offered ad libitum. At the heginning of the experiment, the sheep were treated with a commercial anthelmintic (toloxan®) at a dose of 5 mllhead. Sheep were infected by 5,000 L3 phase nematode larva conslstmg of 80% Haemonchus con/ortus. 9% Trichostrongylus. 6% Cooperia and 5% Oesophagostonum. On the day of 18th after infection. egg count per gram feces were detennined by McMaster method at sensitivity of 1:100. A complete randomized uuhalance design was used to compare the effect of treatments on physiological status, haematocrite, and Ca as well Mg plasma. used McMaster method. Reduction value (RY) of egg count per gram feces was calculated based on a formula as follows: RV ~ (1- (K1/P1*P2/K2))*100%. Result showed that nematode infection changed the physiological status of sheep fed ration which with or without Zn supplementation. Heart beat rate increased significantly (p<0.05) on TO compared with TI and D. Rectal temperature, respiratory rate, blood haematocrite, Ca and Mg plasma were not significantly altered by nematode infection. Key Words: nematode. mineral, physiology and hematocrite.
