Judul: Keragaman Jenis Dan Aktivitas Nyamuk Pada Peternakan Sapi Unit Reproduksi Dan Rehabilitasi Fkh Ipb
Abstrak: Nyamuk merupakan serangga yang penggangu karena mengeluarkan suara bising, memicu alergi pada sebagian orang, mengisap darah, dan menularkan patogen. Selain menularkan penyakit pada manusia nyamuk juga berperan dalam penularan zoonosis seperti JE, RVF, WN, dan lain-lain. Informasi mengenai keragaman jenis nyamuk sebagai vektor zoonosis di Indonesia sangat terbatas. Tujuan dari penelitian ini adalah untuk mengetahui keragaman jenis, fluktuasi populasi dan aktivitas nyamuk pada peternakan sapi di Unit Reproduksi dan Rehabilitasi (URR) FKH IPB. Koleksi nyamuk menggunakan metode BLC dari pukul 18.00 hingga 06.00 pada maret sampai mei 2013. Diperoleh sebanyak 104 nyamuk dari 8 kali pengambilan yang terdiri atas tujuh spesies Culex (Cx. gelidus, Cx. bitaenorhynchus, Cx. quinquefasciatus, Cx. huchinsoni, Cx. pseudosinensis, Cx. fuscocephalus, Cx. tritaenorhynchus) dan satu spesies Armigeres (Ar. subalbatus). Spesies dominan adalah Cx. gelidus (28,85%) dan Ar. subalbatus (17,30%). Aktivitas nyamuk tertinggi terjadi pada pukul 18.00 sampai 19.00.

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: Sintesis BaTiO3 dari BaCl2 dan TiCl4 dengan Metode Hidrotermal
Abstrak: Increasing technology has lead to proliferating electronic equipments. One component of electronic equipment is capacitor, which can be made of barium titanate (BaTiO3). This study aims to synthesize and to characterize BaTiO3 from a mixture of BaCl2 and TiCl4 by observing changes in temperature and the stage of the reaction. This study was carried out in several stages, i.e synthesis of BaTiO3 by hydrothermal method, changes in the reaction steps, changes in pH, compared the results by nonhydrothermal method and characterization by X-ray diffraction (XRD). Based on XRD results, synthesis of BaTiO3, using the method of hydrothermal (T = 120-150 °C), changes in the reaction steps, also in pH, had not been able to produced pure BaTiO3. It can be seen from low intensity of BaTiO3 and presence of other impurities in the form of TiO2 as can be found in all methods including non-hydrothermal method (T = 600 °C).
