Abstrak: Rabies is a zoonotic disease that attacks the central nervous system and able to cause death. The disease is caused by Lyssavirus and transmitted through bites or scratches of an infected animal. Rabies mainly attacks dogs, cats, and monkeys, including humans. This research was aimed to determine the level of knowledge, attitude, and practice; identify factors that influenced the respondent’s practice on rabies; and determine relationship among characteristics, knowledge, attitude, and practice of students of the Faculty of Economics and Management Institut Pertanian Bogor (FEM IPB) on rabies. This research was designed using crosssectional study. Data was obtained with interview using structured questionnaires. The samples size was determined with level of confidence 95%, the expected prevalence of 50%, and the accepted error of 5%, so the samples size was obtained as 281 samples. The results showed that general level of knowledge of students of FEM IPB on rabies was in category of moderate, attitudes of the respondents were in the poor category, but half of respondents were in the good category in practice. Factors which influenced the respondents practice on rabieswas knowledge. This research obtained significant relationship between knowledge and practice (p=0.000, r=0.414).

Abstrak: Rabies is one of the zoonoses that is still a problem around the world, especially in Indonesia. It is an acute infectious disease of the central nervous system caused by the genus Lyssavirus and is transmitted through animal bites, mainly dogs. This research was aimed to determine the level of knowledge, attitude, and practice; determine the relationship among characteristic, knowledge, attitude, and practice of students of the Faculty of Human Ecology, Institut Pertanian Bogor (FEMA IPB) on rabies; and identify factors which influence the respondents practice of rabies. This research was designed by cross-sectional study. The sample size was determined using level of confidence of 95%, expected prevalence of 50%, and accepted error of 5%, so the sample size was obtained as 250 samples. The data were taken by interview of respondents using structured questionnaire. The results showed that the general level of knowledge of students of FEMA IPB on rabies was in the category of moderate to good, but half of the attitudes of the respondents were in the poor category. The majority of respondents had practice towards rabies in good category. This research obtained significant relationship between age and practice (p=0.003; r=-0.629) and between knowledge and practice (p=0.000; r=0.499). Factors which influenced the respondents practice of rabies were age and knowledge.

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.
