Judul: Performa Reproduksi Induk Domba Lokal dengan Manajemen Flushing yang Berbeda
Abstrak: Penelitian ini bertujuan mengevaluasi performa reproduksi induk domba lokal dengan manajemen flushing yang berbeda. Penelitian menggunakan 16 ekor domba betina beranak kedua kali dengan Rancangan Acak Kelompok 4 x 4. Perlakuan terdiri 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. Data dianalisis dengan ANOVA, uji lanjut Duncan untuk peubah konsumsi nutrien, lama kebuntingan, bobot lahir anak, litter size, dan bobot induk beranak. Analisis deskriptif peubah persentase kebuntingan, tipe kelahiran dan uji chi-square (x2 ) peubah sex ratio. Hasil penelitian bahwa manajemen flushing yang berbeda sangat nyata meningkatkan konsumsi lemak (P<0,01), nyata meningkatkan TDN dan bobot induk beranak (P<0,05). Manajemen flushing yang berbeda tidak berpengaruh nyata terhadap lama kebuntingan, total bobot lahir, litter size (P>0,05). Dapat disimpulkan P4 mampu memperbaiki performa reproduksi yaitu bobot induk beranak, persentase kebuntingan, tipe kelahiran kembar, namun tidak berpengaruh terhadap lama kebuntingan, total bobot lahir anak, litter size dan sex ratio, This study was aimed to evaluate local ewes reproductive perfomance with different flushing management. This research used 16 second partus local ewes that were used a Randomized Block Design with 4 x 4. The treatments consisted of P1= without flushing, P2 = Flushing before and after mating, P3 = Flushing before and after mating, midle of pregnancy, P4 = Flushing before and after mating, midle of pregnancy and end of pregnancy. The data were analyzed by ANOVA for parameters nutrient consumption, pregnant periode, birth weight, litter size, and ewe weight at partus. Duncan test if data significant difference. Analyzed descriptively for parameter pregnancy, type of birth and chi-square test for parameter sex ratio. The result showed all treatment did not affected to total birth weight, litter size and pregnant periode (P>0,05). Different flushing management significantly increased consumption of crude fat (P<0,01), TDN, ewe weight at partus(P<0,05). This study concluded that P4 could improve performance reproductive in ewe weight at partus, improve pregnancy and type of birth, but did not affected to total birth weight, littersize, pregnant periode and sex ratio offspring

Judul: Provision of Flushing Rations at Different Phases of the Performance of the Ewes and Pre-weaning Lambs
Abstrak: Penelitian bertujuan menganalisis pengaruh pemberian ransum flushing pada fase berbeda terhadap performa induk dan anak domba pra-sapih. Penelitian menggunakan 12 ekor domba betina beranak kedua dan 18 ekor anak domba. Rancangan acak kelompok (RAK) 4 x 3 dengan perlakuan P1 = tanpa flushing, P2 = flushing sebelum dan sesudah kawin, P3 = flushing sebelum dan setelah kawin serta tengah kebuntingan, P4 = flushing sebelum dan setelah kawin, tengah serta akhir kebuntingan. Peubah yang diukur adalah konsumsi nutrien, bobot induk beranak, pertambahan bobot badan induk beranak, bobot lahir, bobot sapih, mortalitas dan pertambahan bobot badan harian anak pra-sapih. Data dianalisis dengan analisis ragam dan uji lanjut Duncan. Analisis deskriptif digunakan untuk mengetahui tingkat mortalitas. Pemberian ransum flushing pada fase berbeda nyata meningkatkan konsumsi lemak kasar dan PBHH anak umur 14 hari (P<0.05), namun, tidak berpengaruh nyata terhadap bobot induk pasca beranak, PBB induk beranak, bobot lahir, dan bobot sapih anak domba (P>0.05). Dapat disimpulkan bahwa pemberian ransum flushing P4 mampu meningkatkan konsumsi lemak kasar induk domba dan PBBH anak umur 14 hari., The aim of the study was to analyze the effect of giving flushing rations at different phases of the performance of pre-weaned broods and lambs. The study used 12 ewe lambs with second lambs and 18 lambs. Randomized block design (RBD) 4 x 3 with treatment P1 = no flushing, P2 = flushing before and after mating, P3 = flushing before and after mating and in the middle of pregnancy, P4 = flushing before and after mating, middle and end of pregnancy. The variables measured were nutrient consumption, calf weight, calf body weight gain, birth weight, weaning weight, mortality and daily body weight gain of pre-weaning cubs. Data were analyzed by analysis of variance and Duncan's further test. Descriptive analysis was used to determine the level of mortality. Provision of flushing rations in different phases significantly increased crude fat consumption and daily body weight gain of lambs aged 14 days (P<0.05), however, did not significantly affect post-calving brood weight, post-calving brood weight gain, birth weight, and body weight of weaning lambs (P>0.05). In conclusion, P4 was able to increase the consumption of crude fat of the ewes and the daily body weight gain of the lambs aged 14 days.

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.
