Judul: Potensi Aliran Air Sungai Ciapus Sebagai Penggerak Pompa  Hidram
Abstrak: Salah satu sumber daya alam yang memiliki peranan penting adalah sungai. Sungai dapat berfungsi sebagai sumber pasokan air bersih, pengairan lahan pertanian dan kebutuhan lainnya. Sungai Ciapus selama ini belum dimanfaatkan secara optimal di wilayah persemaian IPB Dramaga, Bogor, Jawa Barat. Diperlukan kajian khusus akan potensi air agar dikemudian hari ketersediaan air tetap terjaga. Penelitian ini bertujuan untuk mengetahui profil penampang Sungai Ciapus dan menghitung potensi debit aliran Sungai Ciapus yang dapat dimanfaatkan oleh instansi terkait. Penelitian ini dilaksanakan dengan cara melakukan pengukuran secara langsung pada badan sungai. Pengumpulan data primer untuk mendapatkan nilai tinggi muka air dan kecepatan aliran, sehingga debit sungai dapat dihitung. Hasil penelitian menunjukkan lebar sungai sebesar 22 meter dan bentuk penampang sungai yang relatif berubah. Kedalaman sungai yang terdalam adalah 0,94 meter, sedangkan kedalaman sungai yang terdangkal adalah 0,18 meter. Kedalaman sungai rata-rata sebesar 0,6 meter. Nilai debit maksimum terjadi pada hari ke 9 sebesar 2,98 m3 /detik atau 2.980 L/detik sedangkan nilai debit minimum terjadi pada hari ke 7 sebesar 2,75 m3 /detik atau 2.750 L/detik. Lokasi potensial untuk pemasangan instalasi pompa berada pada koordinat 6o 33' LS dan 106o 43' BT., One of the natural resources that has an important role is the river. Rivers can serve as a source of clean water supply, irrigation of agricultural land and others. So far, the Ciapus River has not been used optimally in the nursery area of IPB Dramaga, Bogor, West Java. A specific study of water potential is needed so that in the future the availability of water is maintained. The research was conducted to produce a cross-sectional profile of the Ciapus River and calculate the potential discharge of the Ciapus River that can be utilized by the relevant agencies. This research was conducted by measuring directly on the river body. Primary data was collected to get the value of water level, and flow velocity, so the river discharge could be calculated. The results showed that the width of the river was 22 meters and the cross-sectional shape of the river isrelatively changed. The maximum depth of the river was 0,94 meters, while the minimum depth was 0,18 meters. The average river depth was 0,6 meters. The maximum discharge of 2,98 m3 /s or 2.980 L/s was occurred on the 9 thday, while the minimum discharge of 2,75 m3 /s or 2.750 L/s was occurred on the 7 th day. The potential location for pump installation is at coordinates 6o 33' S and 106o 43' E.

Judul: Potensi Aliran Sungai Cihideung Sebagai Sumber Air Irigasi Kebun Percobaan Leuwikopo Menggunakan Pompa Hidram
Abstrak: Sungai Cihideung merupakan anak Sungai Cisadane yang dimanfaatkan untuk berbagai kegiatan oleh masyarakat di sekitar Kampus IPB Dramaga. Daerah Leuwikopo yang berada dekat dengan Sungai Cihideung memperoleh air dari hujan dan air tanah. Pemanfaatan air tanah ini memerlukan pompa listrik dan membutuhkan biaya pengoperasian. Pompa hidram dapat menjadi solusi untuk menekan biaya penyaluran air. Untuk itu diperlukan debit sumber air yang sesuai sebagai sumber energi penggerak pompa. Penelitian ini dilakukan untuk menentukan lokasi instalasi pompa hidram, mengetahui profil muka air dan kecepatan aliran, serta menentukan potensi aliran air Sungai Cihideung. Perhitungan debit berdasarkan SNI 8066:2015 dan metode cubic spline interpolation. Lokasi yang dipilih untuk pemasangan pompa berada pada 6o33'57.7" LS dan 106o43'33.09" BT di tepi Sungai Cihideung. Sungai Cihideung memiliki lebar 20,2 m dengan ketinggian air 0,83 hingga 0,86 m dengan kecepatan aliran yang terukur antara 0 hingga 0,3 m/detik. Debit maksimum Sungai Cihideung sebesar 2,47 m3/detik sedangkan debit minimum sebesar 2,17 m3/detik dengan debit rata-rata 2,30 m3/detik. Dari kurva liku kalibrasi debit didapatkan persamaan Q = 167.63H25.697 dengan koefisein determinasi sebesar 0,92., Cihideung River is a tributary of the Cisadane River and was used for various activities by the communities around the IPB Dramaga Campus. The Leuwikopo area was close to the Cihideung River, and got water from rain and groundwater. Utilization of groundwater needed electric pump and required operational costs. Hydram ram pump can become a solution to reduce operational cost. Several condition of water source discharge were needed as the driving energy to operate these pump. This research was conducted to determine the location of hydraulic ram pump installation, to know the water level profile and flow velocity, and to determine the potential discharge of Cihideung River. The discharge was calculated based on SNI 8066:2015 and the cubic spline interpolation method. The selected location of hydraulic ram pump was at 6o33'57.7" S and 106o43'33.09" E on the banks of the Cihideung River. Cihideung River has a width of 20.2 m with a water level around 0.83 to 0.86 meters and the flow velocity was measured around 0 to 0.3 m/s. The maximum discharge of the Cihideung River was 2.47 m3/s while the minimum was 2.17 m3/s with mean discharge of 2.30 m3/s. The equation of rating curve was Q = 167.63H25.697 with a determination coefficient of 0.92.

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.
