Judul: Ecodrain Design of Bandung Advanced Science and  Creative Engineering Space (BASICS) building at Bandung City
Abstrak: Perubahan tata guna lahan akibat pembangunan mengakibatkan perubahan koefisien pengaliran (C). Sumur resapan merupakan metode drainase ramah lingkungan (ecodrain) yang paling praktis. Penelitian ini bertujuan untuk mendesain sistem drainase ramah lingkungan di gedung BASICS. Curah hujan dianalisis dengan metode gumbel, metode log normal, metode normal dan metode log pearson III. Analisis dimensi saluran rencana dilakukan dengan metode trial and error. Hasil analisis debit limpasan sebesar 1,41 m3/detik dan debit rencana yang didapatkan untuk setiap daerah tangkapan air (DTA) sebesar 0,14 m3/detik pada sub-DTA1, 0,05 m3/detik pada sub-DTA2 dan 0,04 m3/detik pada sub-DTA3. Saluran kolektor direncanakan kembali karena saluran tidak mampu menampung debit rencana. Sumur resapan direncanakan kembali karena tidak dapat memenuhi kebutuhan volume minimum menurut peraturan yang berlaku. Perencanaan kembali saluran kolektor menghasilkan desain saluran dengan lebar 1,1 m dan kedalaman 1,3 m. Perencanaan kembali sumur resapan menghasilkan desain dengan dimensi diameter 1,5 m dan kedalaman 2,5 m sebanyak 51 buah., Changes in land use due to development result in the flow coefficient (C) changed. Infiltration wells are the most practical ecodrain method. This study aimed to design an environmentally friendly drainage system in the BASICS building. Rainfall was analyzed by the Gumbel method, the normal log method, the normal method and the Pearson III log method. Dimensional analysis of the design channel was carried out by trial and error method. The results of the analysis of runoff discharge are 1,41 m3/s and the planned discharge obtained for each catchment area (DTA) is 0,14 m3/s in sub-DTA1, 0,05 m3/second in sub-DTA2 and 0,04 m3/s on sub-DTA3. The collector channel was re-design because the channel was unable to accommodate the planned discharge. The infiltration well is planned to be re-design because it cannot meet the minimum volume requirement according to the existing regulations. The re-design of the collector channel resulted in a channel design with 1,1 m width and 1,3 m depth. The redesign of infiltration wells resulted in a design with a diameter of 1,5 m and a depth of 2,5 m as many as 51 unit.

Judul: Perencanaan Sistem Drainase dan Sumur Resapan di Cluster Vega Residence, Pondok Rajeg, Kota Depok
Abstrak: Limpasan yang terjadi akibat hujan merupakan salah satu faktor penyebab terjadinya banjir apabila tidak dikelola dengan baik. Meningkatnya lahan terbangun, menyebabkan peningkatan debit limpasan dan berkurangnya daerah resapan air hujan. Penelitian ini bertujuan merencanakan saluran drainase serta sumur resapan pada Cluster Vega Residence di Kota Depok. Metode yang dilakukan terdiri dari analisis curah hujan, analisis debit limpasan, desain saluran drainase, uji permeabilitas, dan desain sumur resapan. Curah hujan dianalisis dengan metode Gumbel. Dari hasil analisis diperoleh curah hujan rencana yang digunakan untuk perencanaan saluran drainase dengan periode ulang hujan 2 tahun sebesar 122,74 mm dan untuk sumur resapan dengan periode ulang hujan 5 tahun sebesar 150,95 mm. Debit limpasan untuk periode ulang hujan 2 tahun untuk perencanaan drainase sekitar 0,002 – 0,025 m3 /detik. Berdasarkan nilai debit limpasan, saluran drainase direncanakan akan menggunakan u-ditch berukuran 0,3 x 0,3 m pada semua DTA. Volume andil banjir untuk periode ulang hujan 5 tahun yang digunakan untuk perencanaan sumur resapan komunal sebesar 15,63 m3 dengan nilai permeabilitas rata-rata 2,18 cm/jam, sehingga direncanakan 1 buah sumur resapan dengan dimensi 2 x 2 x 4 m., Runoff due to rain is one of the factors causing flooding if it is not managed properly. The increasing of the built-up area will increase runoff and decrease infiltration area. This study aims to plan drainage channels and infiltration wells in the Cluster Vega Residence, Depok City. The method used consists of analysis of rainfall, runoff discharge analysis, drainage channel design, permeability test, and infiltration well design. Rainfall was analyzed by the Gumbel method. The analysis result showed that the planned rainfall used for planning drainage channels with a rainfall return period of 2 years was 122,74 mm and for infiltration wells with a rainfall return period of 5 years was 150,95 mm. The runoff discharge for 2 year rainfall return period for drainage planning is around 0,002 – 0,025 m3 /s. Based on the runoff discharge, drainage channels are planned to be built using u-ditch with a dimension of 0,3 x 0,3 m for all catchment areas. Flood volume for the 5 year rainfall return period for communal infiltration wells planning was 15,63 m3 with an average permeability of 2,18 cm/hour, so one infiltration well was designed with a dimension of 2 x 2 x 4 m.

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.
