Judul: Analysis of water balance and aridity index in catchment and irrigation area of Jatiluhur Reservoir
Abstrak: One of the functions of Jatiluhur Reservoir is to supply irrigation water for 264.000 ha of agricultural land in Pantura, West Java. Most of the farmlands in these area had water deficit during dry season. The purpose of this study were to analyze the water balance and aridity index in catchment and irrigation area of Jatiluhur reservoir, to calculate crop water requirements, irrigation water requirements and efficiency of irrigation channels on farms in the region Pantura West Java, and also to identify and mapping the areas that should receive high priority irrigation water supply. Water balance analysis using Thornthwaite- Mather method was done to obtain water resource potential representation of upstream Citarum watersheed, that hystorically had higher rainfall than its downstream. Irrigation water requirement was calculated by Penman – Monteith method of water balance analysis, using CropWat for Windows version 8.0 software. The result of rainfall analysis showed that dry season in Pantura was occured from April until November (eight months), and wet season was occured from December until March (four months). The result of water balance analysis showed that soils in this region experienced water deficit during April to December. Analysis of aridity index showed that the coastal region Pantura experienced severe drought from June to October, with August as the peak. Water balance of Citarum river and Jatiluhur reservoir indicated that irrigation water demand for agricultural land in Pantura could not fulfilled only by Citarum River, so it need subvention from local resource. Moreover, calculation using CropWat for Windows showed that water requirement for all agricultural land in Pantura was 3.797,7 million m3/year, while data from PJT II showed that the average of irrigation water supply for this area was 5.519,6 million m3/year. It indicated that efficiency of the irrigation Jatiluhur channels was about 68,8%.

Abstrak: Water balance is the balance of the input and output of water somewhere at a certain period, so it can be to determine the amount of the excess or shortage of water. This study aimed to analyze the flow of water and the excess water needs that occur at BBPTP. The procedure consisted of field studies, literature review and data analysis. Based on the analysis, the direction of water flow in the area around the research flowing to the south where there is a Cijengkol river downstream water flow. Based on the analysis of the water needs of the consolidation that has been done can be concluded highest evapotranspiration values occurred in October that is 7.13 mm/day. The highest value of water demand in October is 2.10 lt/sec/ha. The maximum irrigation discharge occurs in the irrigation channel number 7 is 28.01 lt/sec with 13.34 ha area. Based on the analysis of rainfall can be summed value maximum daily rainfall for the area of research at the Center for Rice Research amounted to 76.25 mm with a return period of 2 years and Gumbel distribution. The maximum effluent discharge occurs in the drainage channel number 88 is 117.30 lt / sec with 14.15 ha area.

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
