Judul: Pengetahuan, Sikap, dan Perilaku Masyarakat Kelurahan Pasir Kuda Kota Bogor terhadap Vektor Penyakit Chikungunya
Abstrak: Chikungunya is a disease which has potentially outbreak in the community. At 2008-2010 there has been a Chikungunya outbreak in Bogor which almost 1.919 cases and in the end of 2010 there has been 41 cases of Chikungunya in Subdistric Pasir Kuda. This study was conducted to measure knowledge, attitudes, and people’s behaviour related to the vector of Chikungunya in Pasir Kuda, and it’s relation to people’s characteristics. Out of 110 respondents were selected randomly, then they were interviewed by using questionares. Questions were consisted of common data of respondent’s characteristic, the knowledge of Chikungunya, the attitude and the people’s behaviour of Chikungunya preventions. The data were analyzed using the SPSS 16.0. The results showed that 110 respodents had a good knowledge, attitude, and behaviour as much as 54%, 90%, and 87%, respectively. The statistics test showed that there were significant difference between the education of respondent to their knowledges (p=0.001,p<0.05), and between the knowledge to their attitudes (p=0.001,p<0.05), but there were not significant difference between the knowledge to their behaviours (p=0.198,p>0.05), and between attitude to their behaviours (p=0.214,p>0.05).

Judul: BioecologyAedesspp. Mosquitoes and the Detection of Chikungunya Virus inPasirKuda Village, West Bogor Dictrict
Abstrak: Chikungunya disease was one of the community health problems at PasirKuda Village with an attack rate of 2.96‰ in 2010. This research was done to study the mosquitoe ecology and to detect the presence of chikungunya virus (CHIKV) in Aedes spp. mosquitoes. Field surveys were done from December 2010 until August 2011 to collect mosquitoes and conduct interview to identify community knowledge, attitudes and practices (KAP) on chikungunya, and then in the laboratory to detect chikungunya virus in mosquito samples using Polymerase Chain Reaction (PCR) technique. The resultsshowed that Ae. aegypti breeding place was not in the collecting and saving water container inside the house, but was in another container outside, Ae. albopictus prefer to breed in natural water container and was categorized in moderate density. Ae.aegypti tend to bite and rest inside the house, while Ae. albopictus tend to bite and rest outside the house. Chikungunya virus was successfully detected only in the female Ae. aegypti which was collected on December 2010. The society’s knowledge about chikungunya prevention was categorized as moderate, however, it was not in line with their actions.

Judul: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
