Abstrak: The rate of deforestation and forest degradation in the sector of LULUCF (Land Use, Land Use Change and Forestry) continues to increase along with the increase in land and forest products. In 2009, the release of forest area in Jambi province reached 77,216 hectares, land use 344,305 hectares, and forest area exchange 80,861 hectares. The importance of non-forestry sector development has resulted in the decrease in forested areas (deforestation) and the cover of forested areas (forest degradation). The rate of deforestation in Jambi reached 165,665 hectares, in which 39.75% occurred in West Tanjung Jabung Regency. The use of forest area for non-forestry sector development is set out in the national development policy. The policy changes bring about the changes in the interaction of forest stakeholders to the forest areas. To reduce the rates of deforestation and forest degradation, the government has used REDD + scheme. One scenario in REDD+ scheme is with a moratorium on the use of forest areas. Projected deforestation and forest degradation can be done through dynamic system when a moratorium on forest area utilization is conducted on the intensity of 30%, 50% and 70% out of the forest area use permit in BAU. The implementation of a moratorium can decrease deforestation and degradation about 9% -43%. Implementation of a moratorium of forest area use permit in REDD+ scheme does not provide a very large income. The income of REDD + is only about 0.76 to 1.35 billion USD in every 5-year contract, much lower compared to BAU income of Jambi which reaches USD 678,912 per year and it may threaten 1,290,854 employment opportunities for people.

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.
