Judul: Analisis Kapasitas Simpan Air di Wilayah Kampus IPB Dramaga, Bogor
Abstrak: Bogor Agricultural University (IPB) stage III physical development is being implemented since 2011. Water balance analysis provided an actual description of water storage capacity and its impact on the environmental carrying capacity. The objectives of the study were (1) to analyze status of environmental carrying capacity based on agroclimate zone and to analyze water supply potential, (2) to analyze water storage capacity and (3) land use planning. The research was started since Febuary until June 2012. The research was conducted using climate data and land cover map that processed with Microsoft Excel, CROPWAT 8.0 and ARCGIS 9.3 software. The ratio of water availability and water demand was 0.9 hence the environmental carrying capacity based on water balance was overshoot. IPB Campus agroclimate zone was A1 based on Oldeman classification. The water footprint was 7,9 x 106 m3/year. The region was divided into 14 catchment area (CA). The biggest storage capacity was 235.78 mm/year on CA 11 and the smallest storage capacity was on CA 9a with only 109.51 mm/year. The objectives of land-use planning was to increase water storage capacity. IPB campus as green campus was recommended to improve groundwater recharge and to reach ratio of ground water recharge and surface run-off of 65:35. According to this result it was to recommended to increase vegetation area on CA 4, CA 7, CA 9a, CA 9b, CA 9c and CA 12.

Judul: Rancangan Hidrolika Bangunan Pengendali Limpasan di Wilayah Kampus IPB Dramaga, Bogor
Abstrak: Bogor Agricultural University (IPB) stage III physical development is being implemented since 2011. Along with those development, the surface run-off was increased. The aim of these research were (1) to determine ECC-based on water balance, (2) to predict run-off (3) to do hydraulics design of runoff control structure. Based on water balance, environmental carrying capacity (ECC) was analysed, while run-off in IPB campus Dramaga was calculated by the rational method. Hydraulics design of run-off control structure was obtained by trial and error. The region can be divided into 14 catchment area (CA). The ratio of water availability and water demand was 0,9 hence the ECC of IPB Campus Dramaga was overshoot. Total discharge runoff to Campus IPB Dramaga was 5.66 m3/s. Discharge run-off in each CA was about 0.05 to 1.45 m3/s. Run-off control structure was needed to collect surfacerun-off hence increase water availability. Considering the topography and landuse, land and water conservation was needed in CA 4 and CA 9. CA 4 was suitable for reservoir which supported with sediment trap and drainage channel. CA 9 needed sediment trap for each inlet of Situ Leutik and bigger drainage holes along the side street.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
