Judul: Keragaman jenis dan aktivitas nyamuk pada Peternakan Sapi di Unit Reproduksi dan Rehabilitasi FKH IPB
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: 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.

Judul: Sintesis dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
