Judul: Optimasi pemanfaatan wilayah pesisir berbasis daya dukung bagi pengembangan budidaya tambak udang di Kecamatan Mangara Bombang, Kabupaten Takalar, Provinsi Sulawesi Selatan
Abstrak: The aims of this research are to study land suitability for development of intensive/semi intensive and traditional/traditional plus shrimp culture, to determine carrying capacity, and optimize of land utilization for shrimp culture development. The methods employed in the research include:(i) field survey for assessing the biophysics characteristics of the Mangara Bombang coastal area; (ii) Geographycal Information System (GIS) for suitability analysis; (iii) Carrying capacity analysis using 3 different technique, and (iv) dynamic modelling for optimization. Results of land suitability for intensive/semi intensive shrimp culture showed that 894,284 hectares are highly suitable (SS), 663.071 hectares are suitable (S), and 1517.649 hectares are less suitable (KS). While land suitability for traditional/traditional plus shrimp culture showed that 1148.478 hectares are highly suitable (SS), 1078.667 hectares are suitable (S), and 1031.941 hectares are less suitable (KS). The total water volume of shrimp culture is about 129 152 399.22 m3. The water’s carrying capacity to receive organic waste based on oxygen content about 826 947.02 kg of organic waste /day. Based on that carrying capacity analysis, the generated land allocation for intensive shrimp culture (126 shrimp/m2), intensive shrimp culture (50 shrimp/m2), semi intensive shrimp culture (25 shrimp/m2), and traditional plus shrimp culture (8 shrimp/m2) consecutively are as follow 89.61 hectares, 346.37 hectares, 715.79 hectares, and 1694.91 hectares. While for water’s carrying capacity based on biodegradation rate of organic waste, the generated land allocation for intensive shrimp culture (126 shrimp/m2), intensive shrimp culture (50 shrimp/m2), semi intensive shrimp culture (25 shrimp/m2), and traditional plus shrimp culture (8 shrimp/m2) consecutively are as follow 17.49 hectares, 454.13 hectares, 938.50 hectares, and 2222.25 hectares Waters’s carrying capacity based on assimilation capacity was 70.38 tons of N (1152.13 tons of shrimps) or 47.84 tons of P (2874.tons of shrimps). Based on simulation of dynamic modelling obtained which generated land allocation of high optimization are intensive shrimp culture (126 shrimp/m2) 26.62 hectares, intensive shrimp culture (50 shrimp/m2) 144.69 hectares, semi intensive shrimp culture (25 shrimp/m2) 282.36 hectares, and traditional plus (8 shrimp/m2) 503.43 hectares, with total production 2453.03 tons of shrimp. Optimization economic profit and actual labour are Rp 36 328 006 033 and 1753 people. After that, land allocation scenario 2 for second alternative are intensive shrimp culture (126 shrimp/m2) 12.48 hectares, intensive shrimp culture (50 shrimp/m2) 89.95 hectares, semi intensive shrimp culture (25 shrimp/m2) 168.11 hectares, and traditional plus (8 shrimp/m2) 236.12 hectares, with total production 1371.09 tons of shrimp. Optimization economic profit and actual labour are Rp 19 927 489 483 and 981 people.

Abstrak: Shrimp production at Subdistrict Cantigi Regency Indramayu is still not optimal such as production factor is limited, pond management is not efficient, and farmer’s knowledge about shrimp farming is low. The target research is to analyze optimization input use and financial elegibility at Subdistrict Cantigi. Method used by case study with intake sampel method in the form of purposive sampling. Analyse data use method analyse function produce Cobb-Douglas and analyse finansial. input use Efficiency anticipation got a optimal input is 7/m2 for fry, 0,0217 kg/m2 for feed, 0,0229 hour/m2 to pump, 0,0016 hour/m2 for the preparation labour, 0,0142 hour/m2 for the conservancy labour, 0,0049 hour/m2 for the labour harvest and 0,0031 kg/m2 for saponin. Analyse the production of tiger prawn at optimal condition is R/C 4,51, Pay Back Period 0,42 year, and iii Break Even Point equal to Rp 4.735.940. Invesment criteria analysis with third scenario represent best scenario with value NPV equal to 517.669.132, Net B/C 26.79 and IRR equal to 469%. analysis Sensitivity with change price of feed at 28% indicating that effort still be competent to be run

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
