Judul: Analisis Tata Guna Lahan dan Kecukupan Irigasi di Desa Cihideung Udik dan Desa Cihideung Ilir, Lingkar Kampus IPB
Abstrak: Land and water are the most important elements that support agriculture. Land use is the way of planning land usage of certain area, by dividing it based on specific functions of settlement, paddy field, plantation, industry, etc. The purposes of this research are to identify land use and irrigation availability for planting, and to find out irrigation sufficiency in two villages around campus. Irrigation requirement for the both villages were sufficient. Although the agriculture area is wide, it was only used for planting of palawija. Based on the result of the both villages availability, the land can be planted with the pattern of paddy-paddy-palawija. Irrigation requirements were obtained using Cropwat. In Cihideung Udik Village, the irrigation requirement was 0.07751 l/s and the average daily debit was 22.36 l/s. In Cihideung Ilir Village, the values obtained were respectively 0.29313 l/s and 23.39 l/s. These values showed that both villages have sufficient water supply. The average daily debit were far bigger than the irrigation requirement. A change in land use was also discovered, from farming area to settlement. Total farming area in 2009 (village profile) was less than the one in 2008 (Bakosurtanal).

Judul: Identifikasi dan Analisis Tata Guna Lahan dan Kecukupan Air Irigasi di Dua Desa Lingkar Kampus IPB (Desa Cibanteng dan Desa Benteng)
Abstrak: Water is one of the important factors in agriculture cultivation process. Irrigation planning was very important to guarantee water availability especially for paddy field. Water deficiency influenced paddy development and could reduced its productivity. To fulfill plant water requirement, irrigation must be given in right time and quality. The objectives of this research are to identify and analyse land use, irrigation requirements, and irrigation sufficiency in two villages. The result showed that land use in Cibanteng village and Benteng villages were used for settlement, farming and plantation area. Analysing by Map Info software, showed that settlement and farming area in both villages are increased, but the plantation area is decreased. The irrigation water requirement was calculated by Cropwat software and the result for Cibanteng village in second plant time is 1.47 lt/s and for Benteng village is 0.416 lt/s. The irrigation water sufficiency in Cibanteng village is 26.64 lt/s and in Benteng village is 30.42 lt/s. From that irrigation water sufficiency, the farming area in both villages can planted with paddy twice in a year and once planted with dry crop.

Judul: Beberapa aspek toxoplasmosis pada domba
Abstrak: Toxoplasmosis merupakan penyakit yang disebabkan oleh infeksi protozoa yaitu Toxoplasma gondii. Menurut Kudo (1960), Toxoplasma digolongkan dalam filum Protozoa, sub filum Plasmodroma, kelas Sporozoa, sub kelas Telosporidia, ordo Haemosporidia, famili Babesiidae dan genus Toxoplasma. Selanjutnya Levine et al. (1980) dalam Thomas Cheng (1986), memngklasifikasikan Toxoplasma sebagai berikut : filum Apicomplexa, kelas Sporozoa, sub kelas Coccidia, ordo Eucoccidiida dan sub ordo Eimiriina dengan genus Toxoplasma. Toxoplasma gondii berkembang biak secara seksual dan aseksual. Stadium seksual terjadi di dalam epitel usus ku- cing rumah dan famili Felidae lainnya, sedangkan perkembang biakkan secara aseksual terjadi pada induk semang antara yaitu carnivora, herbivora dan mamalia (Levine, 1973). Kucing mengeluarkan ookista yang belum bersporulasi dalam feses selama 3 10 hari. Hal Ini terjadi setelah kucing tersebut memakan tikus yang telah terinfeksi bradizoit atau trofozoit atau mencerna ookista (Dubey dan Frenkel, 1976 dalam Georgi, 1980). Induk semang antara dapat terinfeksi Toxoplasma gondii bila tertulari ookista bersporulasi dari feses kucing, takhi- zoit atau bradizoit yang terdapat dalam jaringan induk semang antara yang lain, dapat juga terjadi karena terinfeksi takhizoit melalui penularan secara transplasental (Soulsby 1982). Dalam imunitas terdapat satu hal yang menarik yaitu kemampuan Toxoplasma untuk bertahan dalam makrofag yang seca- ra umum dapat membunuh organisme ekstraselular. Menurut Ian Tizzard (1981), respon kekebalan yang perta- ma dari tubuh terhadap parasit Toxoplasma gondii adalah res- pon kekebalan selular (CMI response). Sebagian besar infeksi oleh Toxoplasma gondii tidak menunjukkan gejala klinis yang jelas. Pada domba gejala klinis yang dapat terlihat berupa demam, dispnoe. tremor secara umum dan kadang-kadang terlihat adanya inkoordinasi gerak. Tetapi gejala yang paling umum terjadi adalah plasentitis diikuti abortus atau terjadi kematian foetus pada saat 3 atau 4 minggu terakhir dari kebuntingan. Selanjutnya pada domba gejala dari dikatakan juga gejala yang dapat terlihat betina adalah "circle walking" yang merupakan encephalitis (Soulsby, 1982)…dst
