Abstrak: Natural regeneration is one of many factors which can change species composition and stand structure in Gunung Walat from time to time. The objective of this research is to analyze structure and species composition of vegetations on natural stand in Hutan Pendidikan Gunung Walat, Cibadak, Sukabumi. The location of observation determined by systematic sampling with random start method by using vegetation analysis plot on five strips. The research found 39 species of seedlings, 37 species of saplings, 22 species of poles, 23 species of trees and 21 species of understorey vegetation. Species composition in natural forest of HPGW is dominated by Tarenna fragrans and Bellucia axinanthera. Stand structure consists of stratum A, stratum B, stratum C and stratum E. Stratum A and B are dominated by species Maesopsis eminii while stratum C is dominated by Bellucia axinanthera and Schima wallichii. Stratum E is dominated by Selaginella wildenowii and Clidemia hirta. Tree density decrease exponentially from small diameter trees to large diameter trees which look like inverted J curve. This shows the sustainability of forest stand in the future will be secured.

Abstrak: INTRODUCTION. The existence of forest as an ecosystem is important for life supporting system. This is because the forest produces various benefits, either in the form of services or goods which are very useful for life. In West Java, as in other parts of Indonesia, forests which are still having relatively good condition, are found only in conservation areas. One of the forest conservation areas which is relatively large is Gunung Ciremai National Park (TNGC). The TNGC constitutes a nature conservation area which possesses important ecological function as life supporting system for the surrounding ecosystem. However, information concerning the existing biodiversity in TNGC is still lacking. Therefore, there is a need for more studies to obtain information on biodiversity level and forest composition and structure in TNGC. METHODOLOGY. This study was conducted from August through September 2008 in altitude zones of < 1.000 m above sea level (asl) (lowland zone), 1.000 – 2400 m asl (montane zone), and > 2.400 m asl (sub alpine zone) in Gunung Ciremai National Park, West Java. This study was performed by using vegetation analysis technique which constitutes combination between strip method for tree stage vegetation inventory and plotted line method for forest regeneration inventory. To ease the inventory process, each strip was divided into plots of 20 m X 20 m for tree stage vegetation inventory, 10 m X 10 m for pole stage inventory, 5 m X 5 m for sapling stage inventory, and 2 m X 2 m for seedling stage inventory. Units of vegetation sample plot were placed in west and south slope directions at altitude zones of < 1.000 m asl, 1.000 – 2.400 m asl, and > 2400 m asl. In each slope direction, two sample units with strip length of 200 m and width of 20 m were established. Sampling units were placed in the field with sampling design of systematic sampling with random start. RESULTS AND CONCLUSION. Sub alpine zone exhibited the least number of species (11 species) at all growth stages, as compared with those of montane zone (62 species) and lowland forest zone (58 species). The number of species in the montane zone was relatively greater as compared with that of lowland forest zone. In lowland zone, the dominant species were huru meuhmal (Litsea tomentosa) at seedling stage (IVI 33,7 %), kileho (Saurauia pendula) at sapling stage (IVI 29,3 %), and pine (Pinus merkusii) at pole and tree stages (IVI 144,7 % and 112.8 %). In the montane zone, the dominant species were huru meuhmal (Litsea tomentosa ) at seedling stage (IVI 22,6 %), Litsea sp. at sapling stage (IVI 19,4 %), walen (Ficus ribes) at pole stage (IVI 32.6 %) and saninten (Castanopsis argentea) at tree stage (IVI 45,4 %). At sub alpine zone, the dominant species was plending (Leucaena glauca) at seedling and sapling stages (IVI 64 % and 76,4 %), cantigi (Vaccinium varingifolium) at pole stage (IVI 124,3 %), and jamuju (Dacrycarpus imbricatus) at tree stage (IVI 138,3 %). Index of species diversity (H’) for all elevation zones in TNGC were categorized as high

Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
