Abstrak: One of environment problem nowdays is global warming. Global warming is caused by increasing of temperature in urban area indirectly because increase of Carbon Dioxide (CO2) concentration in the atmosphere. Related on COP 15 about action from result of UNFCCC is to increase CDM system and Copenhagen Accord, then one of effort for decrease CO2 level in urban area is existence of urban forest. Urban forest is CO2 absorbent and has role to control value of CO2, because CO2 is raw material for photosynthesis. The purpose of this research is to determine of sink ability of plant at Bogor Botanical Garden. This research was done at Bogor Botanical Garden for take leaves from ten species and Balai Besar Bioteknologi dan Sumberdaya Genetika Pertanian for analysis of carbohydrate from July until August 2009 at 05.00 WIB; 12.00 WIB; 17.00 WIB; and 20.00 WIB. Tools and materials for this research is plastic, trash bag, camera digital, oven, digital scales, water bath, Cu, Nelson and Carbohydrate reagents, red phenol, aquades, and 10 species (Pterocarpus indicus, Saraca indica, Bauhinia variegata, Brownea hybrida, Eperua falcata, Endertia spectabilis, Dysoxylum cauliflorum, Eusideroxylon zwageri, Neonauclea glabra, dan Bhesa robusta). Mass of CO2 from all species (from 06.00 WIB until 18.00 WIB) are Pterocarpus indicus (14,253 gram), Saraca indica (16,669 gram), Bauhinia variegata (8,238 gram), Brownea hybrida (8,326 gram), Eperua falcata (8,044 gram), Endertia spectabilis (16,581 gram), Dysoxylum cauliflorum (8,479 gram), Eusideroxylon zwageri (15,223 gram), Neonauclea glabra ()15,767 gram, dan Bhesa robusta (9,972 gram). CO2 sink ability influenced by total number of leaves in the plant, then result of sink ability per plant are Pterocarpus indicus (0,456 ton/pohon/tahun), Saraca indica (3,412 ton/pohon/tahun), Bauhinia variegata (0,259 ton/pohon/tahun), Brownea hybrida (1,017 ton/pohon/tahun), Eperua falcata (0,711 ton/pohon/tahun), Endertia spectabilis (1,970 ton/pohon/tahun), Dysoxylum cauliflorum (0,876 ton/pohon/tahun), Eusideroxylon zwageri (31,692 ton/pohon/tahun), Neonauclea glabra (3,460 ton/pohon/tahun), dan Bhesa robusta (1,608 ton/pohon/tahun). Sink ability of all plants consecutive are E.zwageri, N.glabra, S.indica, E.spectabilis, B.robusta, D.cauliflorum, B.hybrida, P.indicus, E.falcata, dan B.variegata.

Abstrak: The increase of temperature in urban area is indirectly caused by the increase of Carbon Dioxide (CO2) concentration in the atmosphere. The increase is caused by land cover alteration and high amount of human activities which uses fossil fuel. The existence of urban forest is one of the ways to coupe the increase of CO2 concentration in the urban atmosphere. Through photosynthesis process, CO2 gas is absorbed by various plants in urban forest and afterwards being released as Oxygen (O2). To control or reduce the concentration of CO2 effectively, in the establishment of urban forest, selection of plants which have maximum ability in reducing CO2 concentration needs to be done. The objectives of this research are to obtain data CO2 sink ability of 15 urban forest plant species in Bogor Agricultural University and to obtain data about the plant species that has the effective CO2 sink ability among the plants which are measured. The measuring of CO2 sink ability was conducted using carbohydrate method. CO2 mass is obtained by converting carbohydrate mass produced in photosynthesis. Other data taken include leaf area and the number of leaves. The higher the leaf area, the higher CO2 sink ability of a leaf. The higher number leaf of a tree, the higher CO2 sink in a tree. The CO2 sink ability of 15 plant species in cm2 of leaf area are (g CO2/cm2/hour): M. caesia 3,793 x 10-4; D. indica 2,180 x 10-4; B. racemosa 1,600 x 10-4; S. campanulata 1,249 x 10-4; M. champaca 1,176 x 10-4; S. malacense 0,820 x 10-4 ; B. capitella 0,805 x 10-4; C. cauliflora 0,734 x 10-4; V. pubescens 0,669 x 10-4; C. inophyllum 0,629 x 10-4 ; M. ferrea 0,479 x 10-4; A. moluccana 0,357 x 10-4; A. dammara 0,268 x 10-4-; and G. dulcis 0,089 x 10-4. The CO2 sink ability of 15 plant species in urban forest in order from the highest are D. indica, M. caesia, S. campanulata, C. inophyllum, B. racemosa, V. pubescens, M. ferrea, C. cauliflora,B. capitella, G. dulcis, M. champaca, S. malacense, A. moluccana, and A. dammara.

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.
