Judul: Lama pemberian ekstrak bawang putih Allium sativum yang optimum pada pakan untuk mencegah penyakit koi herpes virus pada ikan mas cyprinus carpio
Abstrak: This experiment purposed to observe the optimum duration of the application of feed with garlic Allium sativum extract towards immunity of carp fish Cyprinus capio body that infected with Koi Herpes Virus. Experimental design was Complete Random Design that consist of 3 treatments and 3 replications that were : (K-) feed without garlic extract addition and injected with PBS 0,1 ml; (K+) feed with garlic extract addition and infected with KHV 0,1 ml; (A) feed with garlic extract addition (50 gram/kg feed) during 21 days and infected with 0,1 ml KHV; (B) feed with garlic extract addition (50 gram/kg feed) during 14 days and infected with 0,1 ml KHV; (C) feed with garlic extract addition (50 gram/kg feed) during 7 days and infected with 0,1 ml KHV. The result of this experiment showed the high value of survival rate that consist in negative control treatment, each of A and B treatment with value of 91,7% and 83,8% that significantly different with positive control treatment each with value 0%. It showed that time of garlic extract given on feed could affect the immunity of carp fish body toward KHV infection. The optimum result based on survival rate was obtained in garlic extract given during 21 days.

Abstrak: Growth of films Ba0,5Sr0,5TiO3 (BST) 1 M has been done with variation of annealing in hold time 8 hours, 15 hours, 22 hours, and 29 hours at constant temperature 8500C, above Si (100) substrate p-type, by using the sol-gel process method which followed with spin coating process at 3000 rpm for 30 seconds. Optics spectroscopy shows that BST film solar cells with annealing hold time 8 hours, 15 hours, and 22 hours, works effectively in wavelength ≥ 700 nm absorption range. Yet for sample with annealing hold time about 29 hours effectively absorb in ≤ 700 nm wavelength range. It obtained BST film refractive index at range 2.0 to 7.0 to wavelength range ±370-870 nm. Band gap BST film value based on annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours respectively 2.60 eV; 3.12 eV: 3.24 eV, and 2.66 eV. Electrical conductivity value which obtained, indicate that the BST film is classified as semiconductor material with conductivity order 10-5-10-4 S / cm. The result of I-V photovoltaic characterization shows the BST film potentially to be a solar cells device with efficiency according to the annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours in a row are 2.68x10-5%, 3.51x10-5%, 4.53x10-5% and 3.22x10-5%
