      Abstract
      Alih fungsi lahan dapat mengubah laju infiltrasi, dan hal ini akan berdampak pada berkurangnya daerah resapan dan meningkatnya limpasan. Penelitian ini bertujuan untuk merancang sistem drainase di Bogor Barat Agrohills. Perencanaan sistem jaringan drainase dilakukan berdasarkan peta topografi, analisis curah hujan maksimum dan debit limpasan, termasuk perencanaan dimensi saluran, dan gorong gorong. Bogor Barat Agrohills mempunyai pola aliran parallel grid system dan natural system. Saluran primer pada daerah tangkapan air (DTA) 1 sampai 4 masing-masing memiliki lebar dan kedalaman saluran berturut-turut sebesar: (0,7 x 0,9) m, (0,6 x 0,8) m, (0,5 x 0,7) m, dan (0,6 x 0,8) m. Saluran sekunder pada DTA1 sampai 4 masing-masing memiliki lebar dan kedalaman saluran berturut-turut sebesar: (0,4 x 0,6) m, (0,4 x 0,6) m, (0,4 x 0,6) m, dan (0,5 x 0,7) m. Berdasarkan hasil analisis kapasitas, saluran sudah sesuai terhadap volume limpasan. Tipe saluran gorong-gorong yang digunakan yaitu saluran beton bertulang persegi (box culvert). Direncanakan saluran gorong-gorong sebanyak 15 trase pada DTA 1, 2, dan 4. Gorong-gorong pada DTA 4 berukuran (0,7 x 0,7) m dan pada DTA 2 berukuran (0,5 x 0,5) m, sedangkan pada DTA 1 berukuran (0,6 x 0,6) m.
       
      Land conversion can change the rate of infiltration, and this will have an impact on reducing the catchment area (DTA) and increasing runoff. This study aimed to design the drainage system in Bogor Barat Agrohills. The drainage network system planning was conducted based on topographic maps, analysis of maximum rainfall and runoff discharge, including planning for channel dimensions and culverts. Bogor Barat Agrohills has a parallel grid system and natural system. The primary channels in DTA 1 to 4 have width and depth of (0,7 x 0,9) m, (0,6 x 0,8) m, (0,5 x 0,7) m, and (0,6 x 0,8) m respectively. The secondary channels in DTA1 to 4 have width and depth of (0,4 x 0,6) m, (0,4 x 0,6) m, (0,4 x 0,6) m, and (0,5 x 0,7) m respectively. Based on the analysis results of the channels capacity, the channel is suitable for the volume runoff. The type of culvert channel is a rectangular reinforced concrete channel (box culvert). The culverts were design with 15 lines in DTA 1, 2, and 4. The culverts in DTA 4 have a dimension of (0,7 x 0,7) m and in DTA 2 have a dimension of (0,5 x 0,5) m, while in DTA 1 have a dimension of (0,6 x 0,6) m.
