Judul: Model Dinamika Sistem Penyerapan Emisi CO2 di Kota Bogor
Abstrak: Most of the urban pollution is the result of carbon dioxide (CO2) emission from human activities. Green city is a concept of handling these problems by including the environmental aspects in every urban activity. Bogor is one of the cities that have implemented that concept. This research identified CO2 absorption in Bogor and the alternatives to solve the emission problem. CO2 absorption system model was created using software Stella 9.0.2 based on loss – gain emission concept for 30 years prediction. Many urban activities are assumed to increase CO2 emission, while the decrease factor is green open spaces as CO2 sequester. Human activities that contribute to CO2 emission are transportation, industries, energy consumption such as fuel or electricity, house hold waste, and farms. The result of this research, the CO2 emission of Bogor reached 20 027 878 tons in 2042. Combined mitigation in several sectors could reduce CO2 emission by 2 797 667 tons. CO2 emission could be neutralized by reforestation in 2036.

Judul: Model Dinamika Sistem Emisi Sektor Energi dan Penerapan Konsep Kota HIjau di Kabupaten Bogor, Jawa Barat
Abstrak: Emisi merupakan indikator utama peningkatan efek rumah kaca dengan konsentrasi gas CO2. Gas karbondioksida berpengaruh terhadap kenaikan suhu atmosfer yang berdampak negatif terhadap penurunan kualitas lingkungan. Luas Kabupaten Bogor yaitu 298 839.31 ha dengan jumlah penduduk 5 202 097 jiwa, memiliki aktivitas masyarakat serta perekonomian yang tinggi sehingga mengakibatkan emisi sektor energi meningkat dikarenakan penggunaan bahan bakar yang tinggi. Kota hijau atau green city merupakan konsep kota ekologis yang sehat dan ramah lingkungan, efektif dalam mengatasi permasalahan lingkungan akibat pemanasan global. Berbasiskan pendekatan dinamika sistem, emisi berdasarkan hasil pemodelan pada tahun 2033 adalah 12 735 693.06 ton CO2. Emisi tresebut dapat dilakukan penetralan emisi dengan kombinasi atribut kota hijau yaitu green transportation, green energy, green waste dan green open space. Penerapan konsep kota hijau ini turut berkontribusi bagi Indonesia dalam Sustainable Development Goals (SDGs) pada goal nomor tujuh, dua belas dan tigas belas.

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.
