Judul: Analisis dan Rancangan Bangunan Resapan Air Hujan di Sekitar Gedung Graha Widya Wisuda (GWW)-FEMA, Kampus IPB Darmaga, Bogor
Abstrak: The high rainfall in an area and bad drainage systems can affected to surface runoff and flood. For example is Kampus IPB Darmaga, especially around Graha Widya Wisuda (GWW)-FEMA Building. The aims of this research is to design rainwater infiltration structure to solve the problem. This research held by rainfall analysis and soil permeability estimation. Mathematical calculation is performed to determine the volume of flooding, amount of infiltration wells and perforated ditch, and effectiveness of those infiltration structure. Every single infiltration wells can accommodate 0.017 mm rainfall. On the other hand, perforated ditch also designed much as 546 what can accommodate 0.009 mm of rainfall. Designed of infiltration structure could decrease 88 % of total flood as much as 63.65 mm. Remaining surface runoff as much as 7.64 mm capable accommodated drainage has been designed. Material costs needed to build a unit of infiltration wells is Rp 3,100,000.00.

Judul: Analisis Hujan, Debit Puncak Limpasan dan Volume Genangan di Sekitar Gedung Graha Widya Wisuda - FEMA Kampus IPB Darmaga Bogor
Abstrak: IPB Darmaga’s Campus is a region that experienced flood when heavy rain occurred, especially around Graha Widya Wisuda building, Ramin Street, and Kamper Street (FEMA)’s region. This research aims to acquire and analyze rainfall, topography, and landuse data for planning data of zero-runoff drainage system which are peak runoff and volume of puddle data. Based on goodness-offit tests using Smirnov-Kolmogorov and statistical parameter analysis, it is acquired that Gumbel distribution is the best. Maximum daily rainfall (R24) for 2 year return period is 125.68 mm. Topographical condition’s survey produces 3 Water Catchment Area (WCA) with 13 Sub WCA. Results of peak runoff calculation are 0.278 m3/s for Sub WCA 1A, 0.385 m3/s for Sub WCA 1B, 0.297 m3/s for Sub WCA 1C, 0.415 m3/s for Sub WCA 2A, 0.558 m3/s for Sub WCA 2B, 0.160 m3/s for Sub WCA 2C, 1.095 m3/s for Sub WCA 2D, 0.351 m3/s for Sub WCA 2E, 1.069 m3/s for Sub WCA 2F, 2.162 m3/s for Sub WCA 2G, 0.218 m3/s for Sub WCA 2H, and 0.512 m3/s for Sub WCA 2I. The greatest volume of puddle for 1A and 2G Sub WCA are 401.82 m3 and 395.53 m3.

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.
