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.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
