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: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
