Judul: Identifikasi lahan potensial untuk mendukung usulan perencanaan lahan pertanian pangan berkelanjutan
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: Potensi pengembangan lahan rawa lebak untuk perluasan lahan padi di Kabupaten Hulu Sungai Utara Kalimantan Selatan
Abstrak: Agricultural development has an important position for national food security. Increased food security is pursued through the improvement of rice production. The island of Java as the biggest rice producers continue to decrease in size field rice area, so another rice field alternative outside of Java is needed. One of them is nontidal swamp land that is still very wide, such as in Hulu Sungai Utara District South Kalimantan Province. The purpose of this study was to identify suitable land for paddy cultivation and development as well as conservation areas to safeguard the sustainability of farming, knowing the center of rice production and priority directions of development policy. Identify potential rice field using land suitability analysis by remote sensing data and processing data done in ArcGIS 9.3. Land suitability analysis using ArcGIS 9.3 with reference to the criteria established by the Department of Agriculture. Conservation area determined by reference to the Presidential Decree 32 of year 1990 on protected areas. Potential development for rice field is done by overlay spesific analysis of land suitability result and existing landuse are interpreted from the ALOS AVNIR, Landsat and Google Earth images. Centralization of activities carried out by Location Quetion Analysis and policy priorities with SWOT Analysis. The results showed that the potential development of land for rice field is still very widespread, especially in Danau Panggang Subdistrict and Paminggir Subdistrict. Peatland conservation areas are in northern and lake buffer areas in Danau Panggang Subdistrict . River buffer areas spread across the district. Policy priorities are directed to the appropriate utilization of the potential area for rice in the base region with the expansion of paddy fields.

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.
