Abstrak: As natural and dinamic heterogcncous product, soil character are different from one place to another, following the variation factors of soil formation. The accurate soil mapping are needed (0 support regional planning. Study of soil mapping by using key area in Subdistrict of Ciomas and Padarincang of Serang Regency have been done.• The objective of this study are: to learn variation, characteristics, classification and delineation the soil mapping unit in the key area, to explore the soil mapping unit from the key area to entire survey area. That data are compared with data from Team of FEM IPB survey result (Team ofFEM IPB, 2003), that using combination ofLandlorm and Grid System methodes. Determination of key area was conducted at representatif area based on landform analyse from topographic and geological maps. At the key area, field observation of soil characteristic, and classification with Soil Taxonomy (Soil Survey Staff, 1996 and 1999). Was done the observation also for land characteristics. Therefore, design of soil mapping unit covered in the key area and factor that determine delineation of soil mapping unit, could be learned. Extrapolation to entire survey area due to relation of soil mapping unit at the key area with consideration of the landform. Survey area covered 15.365 Ha and the wide of key area 1.482 Ha. Soil subgroup in the key area are Typic Hapludults, Typic Dystrudepts, Lithic Eutrudox, Typic Kandiudox, Typic Endoaqualfs, Typic Hydraquents, Sulfic Tropaquepts and Lithic Troporthents. Soil subgroups based on FEM IPB Team are Thapto-Histic Fluvaquents, Aeric Tropic Fluvaquents, Tropic Fluvaquents, Thapto-Histic Tropic Fluvaquents, Typic Hydraquents, Typic Kandiudox, Aquic Kandiudox, Typic Hapludults and Lithic Tropaquepts. The survey area with volcanic slope landforms, that covered SPT 1, 2, 3, 4, and SPT 5, were found 6 subgroup of soil, while in mapping that done by Team FEM IPB, that covered SPT 4, 6, 7, 8, 9 and SPT 10, were found 7 soil subgroup. Of the closed depression landform (SPT 6 and 7) there were 3 soil subgroups, but according to the FEM IPB Team that covered SPT 1,2,3 and SPT 5 consist 5 soil subgroups. Mapping by using key area produce more accurate soil mapping unit at volcanic slope landforms, but less covering all soil varieties at flat area of closed depression landform. Grid system are better to do in flat survey area.

Judul: Diversity of Soil Characteristics in Field and Its Relation with Landform Spatial Pattern at Agrotechnopark Koleberes, Cianjur
Abstrak: Soil mapping in detail scale needs a high intensity of observation and costly. To decrease the cost, the mapping usually done using an approach of delineation of soil forming factors into homogeneous sets. This approach is based on an assumption that if soil forming factors are homogeneous then the soil characteristics will also homogeneous. However various survey experiences indicated that at sloping areas, soil characteristics still vary although soil forming factors show a high homogeneity. The aim of this research is to study soil characteristics observed from boring with a high observation intensity and to search for a spatial relation between soil characteristics and classification with spatial distribution of landform at a slopping areas. Materials of this research comprised contour map, geology map, existing soil map and soil data covering profile description and its of physic and chemical data. GIS software (Arc View GIS 3.3) was used for spatial analysis of landform. In this research, landform are delineated based on an 1:1000 contour map considering the concept of “Model Diagram of Nine Land Surface” of Dalrymple et. al. (1968; in Darmawan, 1987). Field characteristics of soil were obtained from borings taken at the close distances along slope transects. Observation conducted at some slope transects across various landforms. Soils on research location formed from parent material which is relatively homogeneous under the influence of the same climate, organism and times. Meanwhile relief/ topography shows a high heterogeneity, with differences that even happened at a narrow space. This heterogeneity is reflected by existence of various landform i.e. convex-rather flat-upper slope, straight-flat to rather steep middle slope, concave-rather steep lower slope, etc. Soil field characteristics obtained from boring observation at close distances show very high variations as shown by variation in composition and depth of horizon A and B, soil colour, texture and consistency. This phenomenon could affect the soil classification at family and series level. Toposequently, from upper slope (convex) through the mid slope (straight), to the lower slope (concave) had a tendency to have more complex horizon composition. This phenomenon was due to the dominant process of erosion at the upper slope, and deposition at the lower slope.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
