Judul: Laju Penyerapan Emisi CO2 Berdasarkan Nilai Fluks Karbon pada Ruang Terbuka Hijau (Studi Kasus : Kampus IPB Darmaga Bogor).
Abstrak: Kampus Institut Pertanian Bogor (IPB) Darmaga sebagai pusat administrasi dan perkuliahan memiliki tingkat aktivitas serta mobilitas yang tinggi. Beberapa aktivitas kampus yang menjadi sumber emisi karbondioksida (CO2) ialah aktivitas konsumsi energi listrik, transportasi, pernapasan, dan peternakan. Luasan ruang terbuka hijau (RTH) tersedia yang mencapai dua pertiga bagian, seharusnya memiliki laju penyerapan CO2 yang tinggi pula. Berdasarkan hal tersebut, penelitian ini bertujuan untuk menghitung laju emisi CO2, menghitung laju penyerapan CO2 melalui pendugaan Net Primary Productivity (NPP) serta menentukan penambahan luasan RTH yang dibutuhkan di wilayah sekitar kampus. Hasil penelitian menunjukkan bahwa laju emisi CO2 di sekitar kampus IPB Darmaga mencapai 18 969.2 ton/tahun, dimana 5147.9 ton berasal dari emisi langsung CO2, sedangkan 13 821.2 ton berasal dari emisi tak langsung CO2. Adapun laju penyerapan CO2 oleh RTH kampus mampu mencapai 18 309.1 ton/tahun. Laju penyerapan CO2 yang lebih rendah dibandingkan laju emisi CO2 menyebabkan adanya sisa emisi sebesar 642.3 ton, sehingga dibutuhkan penambahan luasan RTH sebesar 1.1 ha.

Judul: Economic Value Analysis of Reducing Carbon Emissions Alternatives on Bogor Agricultural University Campus in Dramaga District
Abstrak: Sejalan dengan meningkatnya jumlah civitas dan aktivitas di dalam Kampus IPB, kualitas udara semakin menurun. Salah satu hal yang dapat mempengaruhi kualitas udara adalah terjadinya pencemaran udara oleh Gas Rumah Kaca (GRK). IPB kemudian mencanangkan inovasi untuk menjadi Green Campus sebagai upaya mengurangi emisi karbon. Penelitian ini bertujuan untuk: (1) mengidentifikasi jejak karbon yang terdapat di dalam Kampus IPB; (2) menganalisis skenario penurunan emisi karbon di dalam Kampus IPB, dan; (3) mengestimasi nilai ekonomi yang dihasilkan terhadap skenario penurunan emisi karbon yang akan dijalankan. Penelitian ini menggunakan metode analisis deskriptif kuantitatif, metode Weighted Sum Model (WSM), metode analisis biaya manfaat, dan metode benefit transfer untuk mengkaji tujuan-tujuan penelitian. Hasil penelitian menunjukkan 21 jenis aktivitas sumber penghasil emisi karbon di Kampus IPB selama tahun 2020 menghasilkan total emisi sebesar 69.210.132.584 kg/CO2e. Terpilih tiga alternatif upaya penurunan emisi karbon, yaitu alternatif “Zonasi parkir dan menggunakan transportasi umum yang disediakan kampus apabila ingin berkeliling” untuk aspek transportasi, alternatif “Membawa alat makan dan tas belanja sendiri” untuk aspek sampah, dan alternatif “Menggunakan energi seperlunya” untuk aspek energi. Nilai ekonomi dari alternatif aspek transportasi, aspek sampah, dan aspek energi secara berurutan adalah sebesar Rp62.509.413.531, -Rp234.548.061 (tahun pertama) dan -Rp189.735.061 (tahun berikutnya), dan Rp4.677.239.959., In line with the increasing number of civitas and activities on the IPB University, the air quality has kept decreasing. One of the things that can affect air quality is the occurrence of air pollution caused by greenhouse gasses. IPB then launched an innovation to become a Green Campus as an effort to reduce carbon emissions. This study aims to: (1) identify the carbon footprint contained in the IPB University; (2) analyze the scenarios of reducing carbon emissions in the IPB University, and; (3) estimate the economic values of the carbon emissions reduction scenarios that will be implemented. This study uses a quantitative descriptive analysis method, the Weighted Sum Model (WSM) method, the Cost Benefit Analysis (CBA) method, and benefit transfer method to examine research objectives. The results showed that 21 types of carbon emissions source activities on the IPB University during 2020 produced a total emissions of 69.210.132.584 kg/CO2e. Three alternatives for reducing carbon emissions were chosen are the alternative “Parking zonation and use public transportation provided by the campus if you want to stroll around the campus” for the transportation aspect, the alternative “Bringing your own eating utensils and shopping bags” for the waste aspect, and the alternative “Using energy as necessary” for the energy aspect. The economic values of the alternatives aspect of transportation, aspect of waste, and aspect energy respectively are Rp62.509.413.531, -Rp234.548.061 (first year) and -Rp189.735.061 (following year), and Rp4.677.239.959.

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.
