Judul: Identifikasi potensi lahan sawah untuk arahan perencanaan lahan pertanian pangan berkelanjutan di kabupaten pasaman barat Propinsi Sumatera Barat
Abstrak: The West Pasaman Regency, since 1990 the problems faced by the district is agricultural land conversion to the function of paddy fields into plantations palm oil. The passing of Law 41, 2009 on the Protection of Sustainable Food Farming Land (PSFFL) is expected to control the pace of agricultural land use change in particular fields. The aim of this research are: (1) to analyze and identify land use, evaluate land suitability and land area of actual and potential paddy field, (2) to analyze and identify the actual paddy fields of land that has a network of agricultural support infrastructure, (3) to analyze the projection needs of rice field at the district levels, (4) to analyze the public opinion of the main factors affecting the determination for sustainable food farming land and reserve sustainable food farming land, (5) to classify the land for the proposed as the sustainable food farming land and reserve sustainable food farming land. This research was conducted in the West Pasaman Regency began May 2012 until August 2012 using primary data and secondary data. This research used analysis and identification of land use, land suitability evaluation, extensive wetland actual and potential, having the actual wetland agri-food network infrastructure, analysis of the projected needs of the district and sub-district of paddy fields and grouping land. The results showed that land use in the West Pasaman district dominated by oil palm plantations covering an area of 100,642 ha (28.46%) of the total area of land cover, while the use of land for agriculture food such as irrigated and rainfed rice has an area of 27 231 ha (7.70%). Land suitability classes indicate that most of the West Pasaman or about 60% are in the land suitability class S which is technically very fertile for rice cultivation. The West Pasaman district has had a road network actually rice on rice fields and irrigation network has spread in almost all districts. Availability of paddy fields in the West Pasaman Regions still enough to feed themselves for 20 years to come. Physical factors namely availability of actual and potential land take precedence in determining for sustainable food farming land and reserve sustainable food farming land. The actual and potential land available in the West Pasaman district is 39,192 ha. After screening an area of 9918 ha, the actual and potential land has decreased, to 29 274 ha. The actual land area of 27,231 ha initially reduced area of 2756 ha to 24,475 ha. The potential land reduced the original 11,961 ha area of 7162 ha to 4799 ha. Three priorities of AHP/projection/land suitability, administrative boundary, and ethnic considerations might be used to identity sustainable food farming land and reserve sustainable food farming land.

Abstrak: The passing of Law 41, 2009 on the Protection of Sustainable Food Farming Land (PSFFL) is expected to control the pace of agricultural land use change in particular fields. This law is still new so that many of its implementation have not been done, including the planning and establishment of regions, prime land and reserve land. West Java Province is the province's second-largest contributor to the national rice with the support of a potential wetland. Spatial analysis can be used to determine the potential of component sustainable food farming in province based on data and supporting information. The purposes of this study are (1) To analyze the projection needs of wetland at the provincial and district levels, (2) To identify potential land for prime sustainable food farming land and reserve sustainable food farming land at the provincial and district levels, (3) To define potential locations for the proposed as the sustainable food farming region at the provincial and district levels. The results show that the availability of land is the main deciding factor, otherwise suitability of land has not influence in deciding of sustainable food farming area. At the provincial level, the result shows that more general planning area proposed, including assemblage of some small regions, and indication of prime and reserve land. The proposed planning at the provincial level is a reference in the preparation of the proposed planning district, with more a detail data for regions, prime and reserve land along with prediction size of area.

Judul: Koksidiosis Pada Usus Halus Kelinci Yang Disebabkan Oleh Eimeria magna
Abstrak: Penyakit yang disebabkan oleh infeksi protozoa dari genus Eimeria pada usus halus kelinci, disebut kok- sidiosis usus (Intestinal Coccidiosis). Salah satu jenis coccidia penyebabnya adalah E. magna. E. magna ini adalah parasit intraseluler, yang menyerang usus halus kelinci terutama bagian jejunum dan ileum. Dalam siklus hidupnya E. magna mengalami tiga tahap perkembangan, yaitu: 1. Skizogoni. Pada tahap ini terjadi pembentukan skizon, ukurannya berkisar antara 10-20 น. 2. Gametogoni. Pada tahap ini terjadi perkembangan seksual, terjadi lima hari setelah infeksi. 3. Sporogoni. Pada tahap ini terjadi pembentukan spora, bentuk ini dapat menginfeksi kelinci lainnya. Ookista yang bersporulasi dapat menginfeksi kelinci dalam suatu peternakan. Ookista ini berbentuk oval kadang kadang elips, panjangnya 28-42 u dan lebarnya 20-26 u. Apabila kelinci terinfeksi oleh ookista ini, dapat menurunkan berat badan terus menerus dan akhirnya menimbulkan kematian. Kelinci yang berumur muda lebih sering terserang penyakit ini dari pada kelinci dewasa, sehingga sering menyebabkan kerugian pada peternak. Gejala klinis yang terlihat tergantung dari banyaknya jumlah ookista yang termakan oleh kelinci. Kelinci muda sering terinfeksi oleh sejumlah besar ookista yang dapat menyebabkan kematian mendadak tanpa memperlihatkan gejala klinis terlebih dahulu. Pada infeksi akut terlihat gejala-gejala penurunan berat badan, dehidrasi, banyak minum, diare yang hebat dan sering menimbulkan kematian. ...
