Judul: Kajian Brusellosis Pada Sapi Dan Kambing Potong Yang Dilalulintaskan Di Penyebrangan Merak Banten
Abstrak: Brusellosis adalah penyakit menular yang berhubungan dengan pekerjaan, seperti pengantar susu, petugas laboratorium, dokter hewan, inseminator, peternak, pemuliaan sapi dan lain-lain. Penyakit yang disebabkan oleh infeksi B. melitensis disebut undulant fever atau Malta fever. Sedangkan yang disebabkan oleh infeksi B. abortus disebut Bang’s. Keduanya merupakan zoonosis. Penyakit ini dapat terjadi pada hewan domestik (kambing, babi, sapi anjing dan lain-lain) dan manusia, menyebar di seluruh dunia terutama pada negara berkembang. Metode pemeriksaan dengan RBT, CFT, I-ELISA dan SDS-PAGE, Jumlah contoh diperoleh secara bertingkat (multiple state). Ukuran contoh untuk deteksi penyakit secara selektif dalam populasi hewan. Data hasil pemeriksaan dianalisa dengan menggunakan metode statistika deskriptif.

Judul: Pencegahan Bruselosis Pada Sapi Potong Melalui Tindakan Karantina Di Pelabuhan Pantoloan Ke Kalimantan Timur
Abstrak: Sulawesi Tengah merupakan daerah potensial lalulintas perdagangan komoditi peternakan antar Pulau khususnya ke Kalimantan Timur. Sejak 2009 berdasarkan keputusan Menteri Pertanian, Kalimantan Timur merupakan daerah bebas Bruselosis sehingga perlu dilakukan tindakan pencegahan terhadap kejadian Bruselosis di daerah bebas khususnya ternak sapi potong dari Pelabuhan Pantoloan Sulawesi Tengah dengan status daerah belum diketahui terhadap kejadian bruselosis. Tujuan penelitian ini adalah untuk mengetahui tingkat keberhasilan tindakan pencegahan karantina terhadap bruselosis di Balai Karantina Pertanian Kelas II Palu terhadap sapi potong yang akan dilalulintaskan ke daerah bebas negatip terhadap bruselosis setelah dilakukan pengujian serologis Rose Bengal test (RBT) . Penelitian dilakukan dengan cara pengambilan sampel darah pada sapi potong melalui vena jugularis sebelum dilalulintaskan ke antar daerah untuk dikoleksi serumnya. Metode pengambilan sampel yang digunakan adalah 100% sehingga didapatkan sejumlah 244 sampel. Uji skrining menggunakan Rose Bengal test (RBT) dilakukan di Laboratorium Karantina Hewan BKP Kelas II Palu, kemudian dilakukan uji banding Rose Bengal Test (RBT) dan complement fixation test (CFT) di Balai Besar Penelitian Veteriner (BBalitvet) Bogor. Hasil penelitian menunjukkan sejumlah 244 sampel negatif karena tidak ditemukan reaktor positif berdasarkan hasil uji serologis.

Judul: Application of phycocyanin from microalgae Spirulina platensis as light harvesting in anatase TiO2 nanoparticle solar cell.
Abstrak: The dye sensitized solar cell (DSSC) has been assemblied used hybrid titanium oxide (TiO2) film/phycocyanin. The TiO2 film was synthesized by sol gel method with titanium chlorida (TiCl4) as precursor by hydrolysis used sulfuric acid (H2SO4). Furthermore, it calcinated for 2,5 hours in variation of annealing temperature (400oC, 600oC, 800oC, dan 1000oC). In XRD patterns exhibited which annealing temperature at 400oC to 800oC were anatase phase all. When annealed at temperature 1000oC, it caused phase transformation from anatase to rutile. The crystals size according to XRD patterns were 13,75 nm, 20,79 nm, 25,25 nm, 48,88 nm and particle size from SEM images were 43,06 nm, 44,91 nm dan 64,99 nm, 80,40 nm, respectively. The crystals and particle size increased with annealing temperature. The film thickness influenced material absorption. The optical measurement of TiO2 film and TiO2/phycocyanin hybrid film used UV-Vis spectrophotometer. Additional phycocyanin caused peak width of absorbed region from ultraviolet to visible region. The band gap energy of TiO2 can be calculated using the cut off wavelength obtained from the absorbance spectrum of a nanoparticles TiO2 films. Based on intersection between linear and energy (hv) axis. In this study just limited for anatase phase. It was caused anatase band gap is wider than rutile phase. That’s meaningful for solar cell application such as dye sensitized solar cell (DSSC). The absorption coefficient average at difference annealing temperature such as at 400oC, 600oC, 800oC were 8,1600x102, 1,7535x103 and 4,0154x102, where α < 104 include to direct transition. Band gap energy 400oC, 600oC, 800oC were 3,79 eV, 3,59 eV, and 3,35 eV, respectively. Based on this result, exhibition that band gap energy of TiO2 semiconductor film decreased with increasing annealing temperature. Spirulina platensis was cultivated in technical modification (Hastuti) with aeration under light intensity about 3000 lux. The cell density (stationer phase) for eighth day which OD value was more than 0,5. It means, the culture can be harvested. In 80 liters Spirulina platensis culture have been produced biomass dry about 10,46 gram and extracted phycocyanin in dry powders was 5,50 gram. The phycocyanin absorption spectrum at the wavelength of 619,36 nm (visible region) which had relaxation energy was 2,945 eV. The emission peak at the wavelength of 708,55 nm with relaxation energy about 2,793 eV. The Stokes shift based on difference energy absorption and emission calculated about 0,152 eV. Both of this showed phycocyanin can absorbed and radiated the sun light which received. This choice characteristic pigment was a good one related to sensitizer in solar cell application. Integration between light harvesting protein and TiO2 semiconductor surface had important role in improving of output as solar cell materials. The presence of carboxylate group (-COOH) made pigment be more efficient was due to anchored to the surface of TiO2 ampoter. The phycocyanin pigment had carboxylate group which reacted with TiO2 surface formed ester. The carboxylate group increased of dye electronics couple from excited state (p anti bonding orbital) to semiconductor acceptor state (TiO2 conduction band). The samples which made based on annealing temperature variation formed be solar cell respectively. Furthermore, cells be assembled for
