Judul: Model Dinamika Perubahan Hutan dan Lahan dan Skenario Perdagangan Karbon di Provinsi Jambi.
Abstrak: Emisi gas rumah kaca sejak tahun 1970 hingga tahun 2004, terus meningkat sampai 70% dan diantaranya terjadi peningkatan sebanyak 24% selama periode tahun 1990 hingga 2004. Menurut FAO (2010), cadangan karbon pada biomasa hutan Indonesia tahun 1990 sebesar 16.335 juta ton, tahun 2000 sebesar 15.182 juta ton, tahun 2005 sebesar 14.299 juta ton, tahun 2010 sebesar 13.017 juta ton. Cadangan karbon biomasa hutan Indonesia per hektar 2010 mencapai 138 juta ton/hektar. Deforestasi hutan Indonesia berdampak pada penurunan PDB (Product Domestic Bruto) kehutanan terhadap PDB Indonesia. Tahun 1997 proporsi PDB Kehutanan terhadap PDB Indonesia mencapai 1.56% namun di tahun 2000 menurun menjadi 1,18%. Tahun 2008 mencapai 0,81% (Kemenhut 2009) dan di triwulan II tahun 2009 hanya menyumbang 0,85% atau Rp. 4.433,3 Milyar (Kemenhut 2010). Penurunan potensi dan perubahan fungsi penggunaan kawasan hutan yang terjadi terus menerus disebabkan oleh perbedaan kepentingan stakeholder terhadap kawasan hutan dan mempengaruhi institusi yang mengatur tentang pemanfaatan dan penggunaan kawasan hutan. Hubungan ini membentuk suatu sistem yang utuh dan saling mempengaruhi.

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.
