      Abstract
      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.
