Judul: Dampak Penggunaan Zerofly Fence terhadap Populasi Lalat, Perilaku Makan dan Performa Sapi Perah
Abstrak: Indonesia national milk demand increase every year but domestic production is remain constant. FH dairy cow productivity could be enhanced by improved management and the quality and quantity of feed. In addition, external nuisance such as flies factors should also be considered because of their impacts on dairy cattle stress. Besides as vectors of disease, flies also can cause a Myiasis. Disruption of these flies can have an impact that is unhealthy and uncomfortable. This research was conducted in KPSBU administrative area, Lembang district, West Bandung regency, West Java province. The study is determining the effect of zerofly fence to flies population, dairy cattle’s eating behavior and performance. Herd without fence (T1) was compare to herd with zerofly fence (T2) with imbalance replication. The results showed that zerofly fence reduced fly population (P<0.05), increased feed intake (P<0.05), milk production (P<0.05), and reduced the movement of cattle (P<0.05), which prevent stress and decreasing productivity of cattle.

Judul: Keragaman Jenis Lalat Pengganggu dan Potensi Permasalahannya pada Ternak Sapi Potong di Bondowoso
Abstrak: The aim of this research was to study the diversity of species and the dominance of filth flies on beef cattle farms in Bondowoso. In addition, this research was to study the risk due to the presence of filth flies on beef cattle farms. The samples were carried out on 14 traditional farms and 1 communal farm. The samples were taken by sweeping net, then it had identified and analyzed to determine the density of flies. Fly density was expressed with relative abundance and species dominance. The diversity of flies in Bondowoso were Haematobia exigua, Stomoxys calcitrans, Musca domestica, Hippobosca variegata, and Tabanus megalops. The most dominant species was Haematobia exigua. The dominance value of Haematobia exigua on traditional farms was 87.88% and 89.27% on communal farm. A lot of fresh cow dungs in those farms influence the number Haematobia exigua because fresh cow dung was a suitable breeding place for these flies. These flies may carry Stephanofilaria, Trypanosoma evansi, and Bacillus anthracis.

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.
