Abstrak: The aim of this research was to evaluate the effect of garlic in etawah crossbred goat ration on hematology profile and udder performance. This research used 10 etawah crossbred goats devided into 2 treatment groups. First group was given control feed (R0) without garlic, and second group was given control feed plus 0.15% garlic (R1). The ratio of forage to concentrate in dry matter base was 16:84. Parameter measured were dry matter consumption, nutrient intake, body weight gain, hematology profile, and udder performance. The data was compared with T-test analysis. The results showed that 0.15% garlic at ration had not affected to nutrient consumption, hematology profile and udder performance

Abstrak: Goat feeding behavior was an important study in livestock. This study aimed to examine the relationship feeding activity towards consumption, digestibility, and body weight gain in breeding doe Etawah Crossbreeed. This study uses 12 PE doe with an average weight of 40.40 ± 3:19 kg range. This study uses the exploration and correlation analysis. Variables measured were feeding behavior (time spent concentrates, forage consumed within one hour, and a feeding time ) and performance of doe (consumption, digestibility, and body weight gain). Results show the time spent concentrate has a weak relationship with a positive correlation to consumption. Forage consumed within an hour of having a relationship with a weak negative correlation with dry matter digestibility. Feeding time had a weak association with a negative correlation with body weight daily. Feeding behavior was needed in the management of livestock feeding. So that the management could be seen aas feeding their effects on animal performance.

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.
