Judul: DESIGN OF ECO-DRAINAGE IN CONTROLLING DESTRUCTIVE POWER OF RUNOFF, ENVIRONMENTAL POLLUTION, AND INCREASING STORAGE CAPACITY
Abstrak: Sebagian besar permukiman di Indonesia saat ini masih menggunakan sistem drainase konvensional yang mengalirkan air limpasan secepatnya menuju badan air terdekat. Seharusnya air limpasan dapat ditampung dan dimanfaatkan kembali oleh masyarakat sekitar dengan menerapkan sistem eco-drainage. Penelitian ini bertujuan merancang eco-drainage dalam mengendalikan daya rusak air, pencemaran lingkungan, dan peningkatan kapasitas simpan air. Hasil perhitungan debit limpasan dengan metode rasional pada Komplek Anggrek 2 sebesar 1,53 m3/detik. Nilai tersebut melebihi kapasitas saluran terbangun yaitu hanya sebesar 1,04 m3/detik, sehingga diperlukan penambahan saluran baru pada ruas 38-43, 43-40, dan 44-40 yang berfungsi sekaligus untuk mengalirkan air menuju embung. Upaya peningkatan kapasitas simpan air dalam rancangan eco-drainage di lokasi kajian yaitu berupa rancangan embung kecil dengan dimensi panjang 50 m, lebar 15 m, dan kedalaman maksimum 2,5 m sehingga memiliki kapasitas maksimum 1490 m3. Hasil pengujian kualitas air drainase terdapat parameter TSS dan COD yang masih melebihi baku mutu kelas air tiga, sehingga diperlukan unit pengolahan sederhana berupa biofilter dengan media bioball. Total biaya yang diperlukan dalam tindakan konstruksi rancangan eco-drainage yaitu sebesar Rp 722.061.000., Most settlements in Indonesia today still use conventional drainage systems that flow sewage as quickly as possible to the nearest river. The sewage should be able to be stored and reused by the surrounding communities by implementing eco-drainage systems. The research aims to design eco-drainage to control destructive power of runoff, environmental pollution, and increased water storage capacity. The result of the calculation of the discharge by the rational method on Anggrek Complex 2 is 1.53 m3/second. The value exceeds the capacity of the existing channel, which is only 1.04 m3/s, so it is necessary to add new channels on roads 38-43, 43-40, and 44-40 that serve simultaneously to flow water to the pond. The attempt to increase the water storage capacity in the eco-drainage project at the study site is a small pond project with a length of 50 m, a width of 15 m, and a maximum depth of 2.5 m to have a maximum capacity of 1490 m3. The drainage water quality test results have TSS and COD parameters that still exceed the water grade three quality standards, so it requires a simple processing unit of a biofilter with a bioball medium. The total cost required for the construction of the eco-drainage project is Rs 722.061.000.

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: 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.
