Judul: Hubungan curah hujan dengan tinggi permukaan air serta analisa perbedaan tinggi permukaan air di sungai Ciliwung
Abstrak: Masalah khusus ini bertujuan untuk dapat memprediksi terjadinya banjir dari hubungan curah hujan dengan tinggi permukaan air serta dari analisa perbedaan tinggi permukaan air di beberapa tempat pada Sungai Ciliwung (Bogor Depok - Jakarta). DAS merupakan ekosistem yang terdiri dari beberapa unsur dimana unsur utamanya adalah tanah, vegetasi dan manusia serta segala upaya yang dilakukan di dalamnya. Kerusakan yang terjadi pada daerah aliran sungai merupakan penyebab utama tingginya laju aliran permukaan. Terjadinya banjir atau meluapnya air di sungai merupakan salah satu akibat yang sering terjadi. Salah satu DAS yang perlu mendapat perhatian adalah DAS Ciliwung dengan Sungai Ciliwungnya yang mengalir dari daerah puncak sampai ke Teluk Jakarta. Dari hubungan rata-rata curah hujan harian dengan rata-rata tinggi permukaan air harian di Sungai Ciliwung Hulu, Tengah dan Hilir diwakili oleh persamaan: Y = 3.336 X + 13.36 dengan nilai r = 0.953,..dst

Judul: Analisis Curah Hujan, Debit dan Tutupan Lahan di Sub DAS Ciliwung Hulu
Abstrak: Large floods that occurred in the Jakarta in 1996, 2002, 2007 and 2013 respect of Ciliwung watershed. Factors that cause flooding are basically two things that rainfall and land cover. The aim of study to analysis of frequency to predict the opportunity of maximum rainfall in one day, 2 days, and 3 days, as well as to analyze the maximum daily discharge in the return period of 5, 10, 25 and 50 years and to analysis change of land cover in Ciliwung up stream. The analysis result shows that the maximum rainfall in the period of 5, 10, 25 and 50 years are respectively 130 mm, 160 mm, 200 mm and 229 mm/day. While the opportunity of 2 day-maximum rainfall in the same return periods are 168 mm, 202 mm, 248 mm, and 283 mm respectively. The opportunity of 3 day maximum rainfall in the same return periods are 215 mm, 268 mm, 337 mm, and 389 mm respectively. The opportunity of maximum daily discharge in the return periods of 5, 10, 25 and 50 years are 470 m3/s; 565,5 m3/s; 703,4 m3/s, and 819,5 m3/s respectively. The minimum daily discharge in the same return periods are 1,4 m3/s; 1 m3/s; 0,7 m3/s; and 0,6 m3/s respectively.The average increase in the area woke up from 1996 to 2011 was 71.8 ha/year.

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.
