Judul: Kajian Biosekuriti Instalasi Karantina Hewan Sapi Impor di Pulau Jawa
Abstrak: Indonesia imports large number of live cattle as breeding cattle or beef cattle to fulfill its demands for protein of animal origin. In order to prevent animal disease entering and spreading in the country the Government of Indonesia provides animal quarantine premises inside or outside every entry/exit point. Requirements and procedures to establish animal quarantine premises is stated in the Agriculture Minister’s Decree No 34/2006 regarding Requirements and Procedures to Establish Animal Quarantine Premises, and in the Head of Agriculture Quarantine Agency’s Decree regarding Technical Guidelines for Large Ruminant Animal Quarantine Premises. Biosecurity in animal quarantine facilities is one of important factors in preventing spreading of diseases among animals, transmission from animals to human or vice versa and also preventing disease to enter premises. Biosecurity implementation in animal quarantine premises depends on the knowledge, attitude and practices conducted by the officers of the premise, both veterinarian officers and paraveterinarian officers. The aim of this study is to determine the level of biosecurity and the relation among characteristic, knowledge and attitude of veterinarian and paraveterinarian officers on the biosecurity implementation (sanitation, isolation and movement control) in a temporary animal quarantine premises. Data were collected from temporary animal quarantine premises for imported cattle across Java Island. In this study we found that in general the biosecurity implementation in the premises was adequate (62.6%) and good (31.2%). We also noticed that the characteristic of veterinarian officers showed no relation to the biosecurity implementation, while the knowledge and attitude of veterinarian officers showed a strong relation to the biosecurity implementation (p<0.05) with medium correlation level (r = 0.463 and r = 0.524). On the other hand, characteristic of paraveterinarian officers showed no relation to the biosecurity implementation, while the knowledge and attitude of paraveterinarian officers shows a strong relation to the biosecurity implementation (p<0.05) with medium correlation level (r = 0.410 and r = 0.427).

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
