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: Perilaku Menggigit dan Istirahat Vektor Penyakit Chikungunya di Kelurahan Pasir Kuda Kota Bogor
Abstrak: In 2010, outbreak of Chikungunya fever was occured in Bogor with an incidence of almost 372 cases. The disease was transmitted by mosquito, however there were no information about the vectors activity such as biting and resting behaviour. This research was aimed to measure the biting and resting behaviour of vectors of Chikungunya at indoor and outdoor. This study was carried out by the methods mosquitoes landing and resting collection at Pasir Kuda Bogor from 06.00 am to 18.00 pm in December 2010 to March 2011. The collected mosquitoes were identified and analyzed. The result showed that the biting activity of Ae. aegypti was peak indoor at 11.00 am to 12.00 pm (13,63 mosquito/man/hour) and outdoor at 10.00 am to 11.00 am (0,25 mosquito/man/hour). While Ae. albopictus was peak indoor at 15.00 pm to 16.00 pm (0,25 mosquito/man/hour) and outdoor at 15.00 pm to 16.00 pm (2,38 mosquito/man/hour). At period of December to March, Ae.aegypti was found resting indoor, while in December to January it was found outdoor. In addition, Ae. albopictus was found resting outdoor in December to March. However, in December it was found resting indoor.

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
