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.

Judul: Efek Paparan Insektisida Deltametrin Pada Kerbau  Terhadap Angka Gigitan Nyamuk Anopheles vagus pada Manusia
Abstrak: Study was carried out to observe the effect of deltamethrin insecticide application against the biting activity of Anopheles vagus, on human being at Cikarawang, Bogor, since September to November 2004. Insecticide (deltamethrin) was used as lotion and rubbed over the buffaloes body followed by observation the biting activity of mosquitoes (with emphasize on Anopheles mosquitoes group) indoor and outdoor as well. The efficacy of delthamethrin against the Anopheles mosquitoes was observed on the buffaloes prior of trials. Eigth species of Anopheles was collected namely, A. vagus, A. indefinitus, A.aconitus, A.nigerimus, A. annularis, A. barbirostris, dan A. tesselatus. A. vagus is dominant and collected for 743 (84,82 %) over the all collections. The protection period of deltamethrin on the body of buffaloes reached out of 95 % for only 3 days. The protection on the humans body was only observed for Anopheles vagus. Utilization of systemic insecticides on the buffaloes should be attempted to gain the optimal results, in protecting the mosquitoes biting activity.

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.
