Judul: Pendugaan Emisi Gas Rumah Kaca (CO2) Akibat Kebakaran Hutan dan Lahan pada Berbagai Tipe Tutupan Lahan di Provinsi Sumatra Selatan Tahun 2000-2009
Abstrak: Kebakaran hutan merupakan suatu permasalahan serius dan berpengaruh terhadap keseimbangan hutan yang berdampak sangat merugikan baik segi ekologis, ekonomi maupun politik. Oleh karena itu, diperlukan informasi mengenai kejadian kebakaran hutan dan lahan berdasarkan sebaran titik panas (hotspot) beserta emisi karbondioksida yang dihasilkannya, terutama di daerah yang rawan kebakaran hutan dan lahan, salah satunya Provinsi Sumatra Selatan. Tujuan dari penelitian ini adalah menghitung sebaran titik panas (hotspot) sebagai penduga terjadinya kebakaran hutan dan lahan di Provinsi Sumatra Selatan, menghitung estimasi luas area terbakar melalui sebaran titik panas (hotspot), dan menghitung estimasi emisi karbondioksida (CO2) yang dihasilkan dari luas area terbakar berdasarkan penutupan lahan yang berbeda. Penelitian ini dilakukan pada bulan Juli-September 2012 di Laboratorium Kebakaran Hutan, Departemen Silvikultur, Fakultas Kehutanan, Institut Pertanian Bogor. Data yang digunakan adalah data hotspot MODIS dari FIRMS, data curah hujan dari Badan Meteorologi Klimatologi dan Geofisika (BMKG), dan peta tutupan lahan Sumatra Selatan dari RSPO. Hasil analisis menunjukkan bahwa luas area terbakar terbesar di Provinsi Sumatra Selatan terdapat pada lahan pertanian tanah kering bercampur semak yang memiliki luas terbakar masing-masing sebesar 6.172 ha (2000),61.836,81 ha (2005), dan 127.259,53 ha (2009). Emisi CO2 terbesar terdapat pada pertanian tanah kering bercampur semak yaitu masingmasing sebesar 52.475,73 ton (2000), 524.417,17 ton (2005), 1.071.972,41 ton (2009) yang terdapat di tanah mineral, dan emisi CO2 terbesar akibat perubahan penutupan lahan terdapat pada perubahan pertanian tanah kering bercampur semak masing-masing sebesar 3.078.899,73 ton (44,52%) dan 20.443.299,85 ton (50,60%).

Judul: Pendugaan Emisi CO2 sebagai Gas Rumah Kaca Akibat Kebakaran Hutan dan Lahan pada Berbagai Tipe Penutupan Lahan di Provinsi Kalimantan Tengah Tahun 2000-2009
Abstrak: Forest fires became yearly severe problems in Indonesia. Central Kalimantan is one of Indonesia’s provinces that experienced severe forest fires in the last decade. Land conversion may be objected as one of trigger of forest fires that will produce carbon dioxide emissions. The purpose of this research is to calculate green house gas emission especially CO2 using hotspot data based on land use conversion at Central Kalimantan in the period 2000-2009. This research conducted between April and June 2012 at Forest Fires Laboratory, Silviculture Department, Faculty of Forestry, Bogor Agricultural University. The data used are MODIS hotspot data from Fire Information Resources Management System (FIRMS), precipitation data from Indonesian Meteorological, Climatological and Geophysical Agency (BMKG), and land cover map of Central Kalimantan from Roundtable on Sustainable Palm Oil (RSPO). The research results showed that primary forest decreased by 10% in 2009 while palm oil plantation increased more than 190% in 2009 compared to 2005. The numbers of hotspots are increasing from 2000 to 2009. The highest number of hotspots occurred in 2006 as 22,505 hotspot. The number of hotspots occurred on peat land (7,180) is found more than on mineral land (6,391). The increasing burned area from 2000 to 2009 correlates with the increasing of hotspots number on each land covers. Swamp shrubs have the highest burnt area of 113,609 ha, while the highest carbon emission is found from the land cover conversion of swamp shrubs into palm oil plantations as 801,764 tons. The highest carbon dioxide emission on mineral land in Central Kalimantan is found from shrubs in 2005 (459,427 ton). The highest carbon dioxide emission on peat land is found at disturbed swamp forest in 2005 (80,851 ton) and undisturbed swamp forest in 2009 (180,531 ton).

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.
