Judul: Analisis Neraca Air Embung Cikabayan IPB University untuk Lahan Pertanian
Abstrak: Kampus IPB Dramaga yang merupakan kampus pertanian memiliki banyak fasilitas pendukung dalam kegiatan perkuliahannya, salah satu fasilitasnya yaitu kebun percobaan. Embung berfungsi sebagai tempat penyimpanan air yang berlimpah saat musim hujan sehingga membantu mengatasi kekurangan air saat kemarau. Sebelum embung dimanfaatkan sebagai pertanian, perlu dilakukan perhitungan parameter untuk menghitung neraca air, yakni kebutuhan dan ketersediaan air. Ketersediaan air pada Embung Cikabayan dihitung menggunakan metode F.J. Mock. Debit andalan tertinggi terjadi pada bulan Februari, yakni sebesar 0,72 liter/detik. Kebutuhan air irigasi tertinggi terjadi pada bulan Agustus dengan debit sebesar 0,49 liter/detik. Surplus air tertinggi terjadi pada bulan November, yakni sebesar 0,64 liter/detik, sedangkan defisit air tertinggi terjadi pada bulan Agustus dengan besar 0,25 liter/detik. Volume bak penampung direncanakan menggunakan tanki fiberglass sebesar 42 m3 sesuai dengan kebutuhan air irigasi. Untuk perencanaan ini, jenis pipa yang dipilih adalah pipa HDPE dengan diameter 2 inci. Total panjang pipa yang direncanakan adalah 160 meter. Pompa pada sistem perancangan menggunakan tipe Grundfos tipe SP14-6 dengan debit operasional 4,3 liter/detik., IPB University which is an agricultural campus has many supporting facilities in its lecture activities, one of the facilities is an experimental garden. The pond serves as a storage place for abundant water during the rainy season so that it helps overcome water shortages during the dry season. Before the pond is utilized as agriculture, it is necessary to calculate the parameters to calculate the water balance, namely the need and availability of water. The availability of water in Cikabayan Pond is calculated using the F.J. Mock method. The highest mainstay discharge occurs in February, which is 0.72 l/s. The highest irrigation water demand occurred in August with a discharge of 0.49 liters/second. The highest water surplus occurred in November, which was 0.64 l/s, while the highest water deficit occurred in August with a large 0.25 l/s The volume of the reservoir is planned using a fiberglass tank of 42 m3 in accordance with the irrigation water needs. For this planning, the type of pipe chosen is HDPE pipe with a diameter of 2 inches. The total length of the planned pipe is 160 meters. The pump in the design system uses Grundfos type SP14-6 with an operational discharge of 4.3 l/s.

Judul: Analisis Neraca Air Embung Cikabayan IPB University dengan Menggunakan Metode NRECA
Abstrak: Embung Cikabayan berada di IPB University dan terletak dekat Kebun Percobaan Cikabayan. Embung ini nantinya akan dimanfaatkan untuk pembangkit listrik mikrohidro, ekowisata, dan sebagai suplai air untuk Kebun Percobaan Cikabayan. Hal ini sejalan dengan penuturan petugas kebun, bahwa suplai air untuk operasi masih kurang dari suplai pusat IPB. Tujuan dari penelitian ini adalah untuk mengetahui potensi air Embung Cikabayan dan nilai kebutuhan air tanaman pada Kebun Percobaan Cikabayan, serta menganalisis neraca air pada Embung Cikabayan. Ketersediaan air dihitung dengan menggunakan metode NRECA berdasarkan data curah hujan dan evapotranspirasi. Kebutuhan air tanaman dihitung dengan menggunakan aplikasi CROPWAT 8.0. Perhitungan ketersediaan air dengan menggunakan metode NRECA menghasilkan nilai rata-rata debit per tahun sebesar 0.0132 m3/detik. Kebutuhan air irigasi dari hasil aplikasi CROPWAT 8.0 hanya terjadi pada bulan Juli sebesar 0.31 liter/detik dan pada bulan Agustus sebesar 0.39 liter/detik. Simulasi neraca air dengan debit andalan 80% menggambarkan bahwa Embung Cikabayan dapat memenuhi kebutuhan air tanaman pada Kebun Percobaan Cikabayan., The Cikabayan pond located at IPB University, near the Cikabayan Field. This pond will be used for micro-hydro power plants, ecotourism, and as a water supply for the Cikabayan field. This is in line with the statement of the gardener, that the water supply for operations is still less than the supply from the IPB center. The purpose of this study were to determine the water potential of the Cikabayan Reservoir and the value of plant water requirements at the Cikabayan Experimental Garden and to analyze the water balance of the Cikabayan pond. Water availability is calculated using the NRECA method based on rainfall and evapotranspiration data. Plant water requirements are summed using the CROPWAT 8.0 application. Calculation of water availability using the NRECA method produces an average annual discharge value of 0.0132 m3/s. The irrigation water demand from the CROPWAT 8.0 application only occurs in July at 0.31 liters/s and in August at 0.39 liters/s. The water balance simulation with 80% depandable flow illustrates that the Cikabayan small dam can supply the water needs of the Cikabayan field.

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.
