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: 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.

Judul: Studi Histopatologi Organ Hati Hamster (Mesocricetus auratus) yang Diinfeksi Coxiella burnetii
Abstrak: Coxiella burnetii (C. burnetii) is a bacterial like organism that causes Query fever. The aim of this study was to describe the liver histopathology of hamsters after infected by C. burnetii intraperitoneally. Hamster were divided into two groups. All hamster liver were collected for histopathological examination using hematoxylin-eosin staining (HE) and immunohistochemical staining (IHC). HE staining results in hamsters group I which were injected with C. burnetii’s antigen showed 3 out of 4 has granuloma which are typical of C. burnetii infection. All hamsters group II which were injected with hamsters group I’s spleen extracts showed granuloma in microscopic observation. IHC staining revealed all hamsters liver has positive result. Beside granuloma lesion, all hamster’s liver show acute hepatitis symptoms. The microscopic lesion of acute hepatitis showed the inflammatory cell accumulated in liver perifer, degeneration of hepatocytes cells, activation of lymphoid follicles, as well as congestion in small and large blood vessels.
