Judul: Potensi Hutan Kota sebagai Alternatif Substitusi Fungsi Alat Pendingin Udara (Air Conditioner) di Kota Surabaya
Abstrak: Most of the societies used the air conditioners to reduce overwarming. However, besides apart from costly, air conditioner only increase global warming. One attempt to control temperatures in urban areas is by developing an urban forest. The purpose of this research was to assess the ability of urban forest vegetation in absorbing heat in replacing air conditioner, hence the efficiency of urban forest. The research would be known was conducted in the city of Surabaya. The research was initiated by performing measurements at room with Room Air Conditioner methods. The potential of urban forest made through of measuring the heat flux density on vegetation. The result show that the heat absorption ability of the trees was 2958.7 KJ/h (Bratang urban forest) and 2589 KJ/h (Wonorejo urban forest). One unit of 1 PK air conditioner ( capacity of 9495 Kj/h ) can be substituted by 3-4 trees, one unit of 1.5 PK air conditioner (capacity of 18990 Kj/h ) can be substituted by 6-7 trees and one unit 2 PK of air conditioner (capacity 28458 Kj/h) can be substituted with 9-10 trees. The total efficiency of the eight rooms studied was found token Rp 22.811.042,-/year (Bratang Urban Forest) and Rp.20.365.265,-/year (Wonorejo Urban Forest). Thus, The development of urban forests to replace air conditioner is rational because it could significantly save the cost of a room spending.

Judul: Potensi hutan kota sebagai alternatif substitusi fungsi alat pendingin ruangan (Air Conditioner) (Studi Kasus di Kampus IPB Darmaga)
Abstrak: Kota merupakan lingkungan yang memiliki tingkat pembangunan infrastruktur, kepadatan penduduk dan segala aktifitasnya sangat tinggi, sehingga mengakibatkan peningkatan suhu udara perkotaan. Pada umumnya masyarakat menggunaan alat pendingin ruangan (Air Conditioner) di rumah-rumah maupun perkantoran. Upaya tersebut tidak murah mengingat biaya yang dibutuhkan untuk memperoleh dan mengoperasikan alat pendingin tersebut relatif tinggi dan belum terjangkau oleh masyarakat golongan menengah ke bawah. Selain itu, Air Conditioner (AC) memiliki banyak kekurangan antara lain yaitu menyebabkan dehidrasi, potensi infeksi bakteri Legionella sp., panas sebagai efek samping justru menambah pemanasan suhu udara di luar ruangan, dan merupakan salah satu penyebab terjadinya Global Warming. Sementara itu, vegetasi hutan kota dapat memberikan manfaat ekologis pada lingkungan sekitarnya, salah satunya dapat mereduksi peningkatan suhu udara di perkotaan. Tujuan penelitian ini yaitu untuk mengkaji kemampuan vegetasi hutan kota dalam menyerap panas serta potensinya untuk menggantikan fungsi alat pendingin ruangan, sehingga dapat diketahui nilai efisiensi hutan kota.

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.
