Abstrak: Mosquitoes are insects that cause the most health problems in society, as nuisance insects and vector of various diseases such as malaria, dengue hemorrhagic fever, chikungunya, Japanese Encephalitis, dirofilariasis, filariasis, St. Louis Encephalitis and West Nile Virus. Application of zooprophylaxis as the utilization of cattle to divert mosquito bite from human to animal has not been done in Indonesia. This study was aimed to determine the effect of the placement of cattle around houses to reduce mosquitoes biting to human. Mosquitoes collection on human were done by Bare Leg Collection (BLC) around the houses with and without cattle placement. In the meantime, mosquitoes which come to cattle caught by Magoon trap. The result showed that the density of Cx. sitiens which known as vector of Japanese Encephalitis was 12,05 mosquitoes/man/hour at the houses with cattle and was 16,31 mosquitoes/man/hour at houses without cattle, and very high in cattle was 54,38 mosquitoes/cattle/hour. Density of Anopheles which known as vector of malaria did not show the difference between around houses with and without cattle placement. An. vagus density at house with or without cattle were same (0,01 mosquitoes/man/hour), but very high at cattle (6,12 mosquitoes/cattle/hour). This research showed that placement of cattle as zooprophylaxis application has good potency to reduce mosquito contact to human, which is means it could reduce mosquitoes borne diseases transmission.

Abstrak: Mosquitoes are annoying insects because of a noise, blood sucker, transmit pathogens, and trigger allergies in some people. Mosquitoes play a role in the transmission of zoonoses such as JE, RVF, WN, etc. Information about diversity of mosquitoes that play as vectors on zoonoses in Indonesia has limited. The purpose of this study was to determine the diversity, population fluctuation, and the activity of mosquitoes at cattle farm in Unit Reproduction and Rehabilitation (URR) Bogor Agricultural University. Mosquitoes was collected by BLC method from 6 pm to 6 am on March to May 2013. There were 104 mosquitoes from 8 times collections, consisted of 7 species Culex (Cx. gelidus, Cx. bitaenorhynchus, Cx. quinquefasciatus, Cx. huchinsoni, Cx. pseudosinensis, Cx. fuscocephalus, Cx. tritaenorhynchus) and one Armigeres (Ar. subalbatus). The dominant species was Cx. gelidus (28.85%) and Ar. subalbatus (17.30%). The highest mosquitoes activity was discovered at 6 pm to 7 pm.

Judul: Analisis Sifat Kristal Dan Sifat Optik Pada Keramik SrTiO3 Didadah RuO2
Abstrak: Sintesis keramik Stronsium Titanat (SrTiO3) didadah Rutenium Oksida (RuO2) metode reaksi padatan (solid state) telah berhasil dilakukan. Keramik di annealing dengan suhu 850C. Karakterisasi keramik Stronsium Titanat (SrTiO3) didadah Rutenium Oksida (RuO2) dengan variasi konsentrasi pendadah (0%; 0,5%; 1%) dilakukan untuk mengetahui pengaruh konsentrasi pendadah Rutenium Oksida (RuO2) terhadap sifat kristal dan sifat optik pada keramik Stronsium Titanat (SrTiO3). Struktur kristal keramik berbentuk kubus dengan ukuran parameter kisi a=b=c berturut-turut senilai 3,905 Å; 3,905 Å; dan 3,903 Å. Sifat optik keramik ditunjukkan dengan optik longitudinal dan transversal yang berada pada bilangan gelombang 261-937 cm-1 dan nilai energi celah pita sebesar 3,48 eV-3,56 eV., The synthesis of Strontium Titanate (SrTiO3) ceramic doped with Ruthenium Oxide (RuO2) using the solid-state reaction method has been successfully conducted. The ceramics were annealed at a temperature of 850°C. Characterization of Strontium Titanate (SrTiO3) ceramic doped with Ruthenium Oxide (RuO2) with varying dopant concentrations (0%; 0.5%; 1%) was performed to understand the influence of Ruthenium Oxide (RuO2) dopant concentration on the crystal properties and optical properties of Strontium Titanate (SrTiO3) ceramics. The ceramic's crystal structure is cubic with lattice parameter sizes of a=b=c, respectively, measuring 3.905 Å; 3.905 Å; and 3.903 Å. The optical properties of the ceramic are indicated by longitudinal and transverse optics in the wavenumber range of 261-937 cm-1 and a bandgap energy value ranging from 3.48 eV to 3.56 eV.
