Judul: Nutrient Digestibility of Late Pregnancy Local Ewes Fed  Flushing Ration with Different Frequency
Abstrak: Tujuan dari penelitian ini adalah mengevaluasi kecernaan nutrien pada domba lokal fase akhir kebuntingan yang diberi ransum flushing dengan frekuensi pemberian yang berbeda. Penelitian ini menggunakan 12 domba lokal fase akhir kebuntingan, dengan rataan bobot badan 49,96 kg ± 9,67. Penelitian ini menggunakan Rancangan acak kelompok (RAK) dengan 4 x 3, yaitu P1 (tanpa flushing), P2 (flushing pada saat sebelum dan sesudah kawin), P3 (flushing pada saat sebelum dan sesudah kawin, dan pertengahan kebuntingan), dan P4 (flushing pada saat sebelum dan sesudah kawin, pertengahan, dan akhir kebuntingan). Konsentrat flushing mengandung 2% minyak kelapa dan 5% minyak ikan lemuru. Parameter yang diukur yaitu konsumsi nutrien dan kecernaan nutrien. Data yang diperoleh dianalisis menggunakan ANOVA dan apabila berbeda nyata diuji lanjut menggunakan uji Duncan. Hasil menunjukkan perlakuan nyata mempengaruhi (P<0,05) konsumsi lemak kasar dan kecernaan bahan kering, protein kasar, serat kasar, dan BETN, tetapi tidak nyata mempengaruhi konsumsi bahan kering, protein kasar, serat kasar, dan BETN, serta kecernaan lemak kasar. P3 meningkatkan kecernaan bahan kering, protein kasar, serat kasar, dan BETN. P4 meningkatkan konsumsi lemak kasar dan cenderung meningkatkan kecernaan lemak kasar, The aim of this research was to evaluate the nutrient digestibility of late pregnancy local ewes given flushing ration with different frequency. This research used 12 local ewes in the late pregnancy, with average body weight 49,96 ± 9,67 kg. This research used a Randomized block design (RBD) with 4 x 3 . The treatments were P1 (without flushing), P2 (flushing at the before and after mating), P3 (flushing at the before and after mating, and middle of pregnancy), and P4 (flushing at the before and after mating, middle, and end of pregnancy). Concentrate flushing containing 2% coconut oil and 5% Lemuru fish oil. The measured parameters were nutrient consumption and nutrient digestibility. The data were analyzed using ANOVA and any significant differences were further tested using Duncan Test. The result showed that the treatments significantly affected (P<0,05) the consumption of crude fat and digestibility of dry matter, crude protein, crude fiber, and N-free extract, but it did not affect the consumption of dry matter, crude protein, crude fiber, and N-free extract, as well as the digestibility of crude fat. In conclusion, P3 increased digestibility of dry matter, crude protein, crude fiber, and N-free extract. P4 increased nutrient consumption of crude fat.

Judul: The Effect of Different Flushing Feed Management on Local Ewes Hematology at the End of Pregnancy
Abstrak: Penelitian ini bertujuan menganalisis efek dari manajemen pakan flushing yang berbeda pada hematologi domba lokal di akhir kebuntingan. Ternak yang digunakan sebanyak 12 ekor domba lokal betina laktasi kedua dengan berat rata- rata 29,75 ± 6,02 kg dan ditempatkan di kandang individu. Penelitian menggunakan Rancangan Acak Kelompok 4 x 3 yang dikelompokkan berdasarkan bobot badan ternak. Perlakuan terdiri atas P1 = Tanpa flushing, P2 = Flushing sebelum dan setelah kawin, P3 = Flushing sebelum dan setelah kawin serta tengah kebuntingan, P4 = Flushing sebelum dan setelah kawin, tengah serta akhir kebuntingan. Perbandingan hijauan dan konsentrat dalam ransum adalah 30:70 berdasarkan bahan kering. Parameter yang diamati adalah hematokrit, kadar hemoglobin, Butir Darah Merah (BDM), Butir Darah Putih (BDP), dan persentase diferensiasi leukosit yang terdiri dari limfosit, monosit, neutrofil, basofil, dan eosinofil. Analisis data menggunakan uji ANOVA dan Duncan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P>0,05) terhadap hematokrit, kadar hemoglobin, Butir Darah Merah (BDM), dan diferensiasi leukosit. Manajemen flushing berpengaruh signifikan (P<0,05) terhadap Butir Darah Putih (BDP). Dapat disimpulkan flushing sebelum dan setelah kawin, tengah dan akhir kebuntingan meningkatkan nilai hematologi ternak dibandingkan dengan perlakuan tanpa flushing, flushing sebelum dan sesudah kawin, flushing sebelum dan sesudah kawin serta tengah kebuntingan., This study was aimed to analyze the effects of different flushing feed management on the hematology of local sheep at the end of pregnancy. This research used 12 second lactating local ewes, average weight was 29,75 ± 6,20 kg and placed in individual cages. This research used a randomized block design (RBD) with 4x3 that are grouped based on body weight of ewes. The treatments consisted of P1 = without flushing, P2 = flushing during before and after matting, P3 = flushing during before and after matting, and in the middle of pregnancy, P4 = flushing during before and after matting, in the middle and end of pregnancy. Ratio forages and concentrate in the ration were, 30:70 % dry matter basis. The parameter observed were hematocrit, hemoglobin level, Red Blood Cell (RBC), White Blood Cell (WBC), and leukocyte diferentation consisting of lymphocytes, monocytes, neutrophils, basophils, and eosinophils. The data were analyzed using ANOVA and Duncan test. The results showed that the treatment did not significant effect (P>0,05) on hematocrit, level hemoglobin, Red Blood Cell, and leukocyte diferentation. Flushing management had significant effect (P<0,05) on White Blood Cell (WBC). This study concluded that treatment with flushing before and after mating, midle of pregnancy and end of pregnancy increases hematological value of cattle compared to treatments without flushing, flushing before and after mating, and flushing before and after mating, midle of pregnancy.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
