Judul: Peran Cagar Biosfer Cibodas dalam Penyerapan CO2
Abstrak: Biosphere reserves are protected areas which the existence is well known globally as an area for promoting the balance relationship between human beings and the environment. Biosphere reserves have three zones namely the core zone as conservation areas, the buffer zones as a protective area of the core zone, and the transition zones that are intended for regional sustainable development. Cibodas Biosphere Reserve is one of the seven existing biosphere reserves in Indonesia with the largest mountains rain forest ecosystem. One of the environmental services provided by the Cibodas Biosphere Reserve is the ability to absorb CO2. The objective of this study is to estimate the value of the absorption of CO2 in Cibodas Biosphere Reserves using carbon flux value indicated by the value of NPP. The results of this study provide the highest value of carbon flux in the core zone occurred in 2006 that is equal to 1689.2 gC/m2/year, the highest value of carbon flux at buffer zone and transition zone occurred in 2006 are 1543,4 gC/m2/year and 1197,3 gC/m2/year, consecutively. The highest total potential of CO2 absorption in the core zone occured in 2006 reached 1,473,572.4 tons/year, at the buffer zone occured in 2006 reached 705,096.4 tons/year, and the transition zone occurred in 1991 reached 1,036,069.6 tons/year.

Judul: Analisis perubahan penggunaan/penutupan lahan di area cagar biosfer cibodas dalam mendukung keberadaan Taman Nasional Gunung Gede Pangrango
Abstrak: An increasing number of population caused land use/land cover change in Cibodas Biosphere Reserve. One of the approach to rapidly assess land use conversion is by using remote sensing technology. Therefore, the purposes of this study are : (1) to analyze land use/land cover change in 1999 and 2011 and the factor that affecting land use/land cover changes; (2) to identify people preference about land use/land cover change that can be tolerated; (3) predicting land use/land cover allocation approach with Cellular Automata (CA) and (4) to conduct controlling scenario land use/land cover changes in the Cibodas Biosphere Reserve that can support the sustainability of Mount Gede Pangrango National Park. The result showed the form of land use in 1999 was dominated by dry field and mixed farms, amounting to 44.25% and in 2011 the dominance of dry field and mixed farms was reduced to 38.16% accompanied with an increase in settlements from 16.19% to 20.41%. Based on AHP result, land use/land cover change is caused by population growth, source of income, slope, elevation and soil type. Land use/land cover change that can be tolerated by society is changing forests into dry field and mixed farms which have a value of 0.249 or 24.9%, and from dry field and mixed farms to residential with a value of 0.206 or 20.6%. Landuse prediction in 2023 show that dry field and mixed farm is 34,34 %, forest 30.97%, settlements 23.39%, fields 11.14%, edelweis 0.08%, grass / shrub 0.05% and 0.03% of water bodies. There is three scenarios to control land use/land cover change in Cibodas Biosphere Reserve

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
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.
