Judul: Model Dinamika Simpanan Karbon Akibat Perubahan Kawasan Hutan di Provinsi Sumatera Barat
Abstrak: The rate activity of Forest landuse changed in the world was increase. It caused by a reduced ability from forest to absorb the carbon. Based from this fact was considered the need of a researched at a scope certain areas to known the reserved carbon available and known any factor influenced it. The point of this researched was to made a dynamics model and known the factor that effected a change of forest areas, measured the dynamics of carbon stock in the forest of West Sumatera Province and made an alternative scenario that could be positve impact on the mistress of carbon that was exist. Based on this research was known deposit of carbon stock decreased every year. There was a decline of 48.448.999,07 ton or decreased by 949.980,38 ton a year. From this researched was known forest carbon in Sumatera Barat was decreased caused of transmigration and mining activity. Scenario like extended HTI cycle, used 30 years cycle on HPH and restrictioned changed the region could provided positive effect on saved carbon that was exist.

Judul: Model Dinamika Simpanan Karbon Kawasan Hutan di Provinsi K Kalimantan Barat
Abstrak: The issue of global warming is growing, that putting forests as one of solutions to decrease the concentration of greenhouse gases (GHGs) in the atmosphere. This study describes the tendency of the usage and utilization of forest areas on west Kalimantan province and its relationship to the stock of carbon in forest areas by using system dynamic method. The simulation of model until 2011 shows the occurrence of deforestation that causes loss of stock carbon 0f 62,74 megatons. The simulation of model up to 2050 on Business as Usual (BAU) will cause carbon stock losses amounted to 162,82 mega tons due to land conversion activities. The rate of forest degradation trough the year 2011 has resulted in carbon stock losses about 300 megatons or equivalent to 27,28 megatons/year. The simulation up to 2011 showed the value of plantation forest carbon stock reach 42,96 megatons. This number will continue to increase until it reaches 84,23 megatons by 2050. The application of Reduced Impact Logging (RIL) scenario, forest plantation harvesting cycle, and provincial conservation policy practice can reduce loss of carbon stock rate.

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.
