Abstract

ABSTRAK Kelurahan Demang Lebar Daun Kota Palembang, yang setiap tahunnya saat musim penghujan selalu mengalami banjir yang disebabkan oleh topografi berupa dataran rendah sehingga ketika musim penghujan menerima aliran air dengan debit yang cukup besar. Kolam retensi Rumah Sakit Siti Khadijah di Jalan Demang Lebar Daun merupakan kolam retensi yang mampu menampung kelebihan air pada daerah tersebut, namun kolam ini sudah tidak mampu mengatasi permasalahan banjir salah satu penyebabnya karena kapasitas kolam retensi ekisting yang tidak sesuai dan masalah endapan sedimentasi. Metode penelitian yang digunakan yaitu survei pengukuran untuk memperoleh data luas penampang dan kedalaman kolam, selain itu juga pengambilan sampel sedimen pada titik inlet, outlet dan tengah kolam untuk dilakukan analisis saringan dan berat jenis di laboratorium. Hasil penelitian menunjukkan bahwa berdasarkan analisa sedimen dengan metode Frijlink diperoleh bahwa debit sedimen dasar terbesar yaitu 5,192 x 10-6 m 3 /s/m, volume sedimen dasar (bed load) sebesar 3,7832 x 10-6 m 3 /s dan volume timbunan kolam retensi terbesar yaitu 25.788,25 m 3 /tahun. Kata kunci : kolam retensi, Sedimentasi, Sedimen dasar, Volume timbunan. ABSTRACT Kelurahan Demang Lebar Daun Palembang City, which every year during the rainy season always experiences flooding caused by the topography in the form of lowlands so that during the rainy season it receives a large amount of water flow. The retention pond of the Siti Khadijah Hospital on Jalan Demang Lebar Daun is a retention pond that is able to accommodate excess water in the area, but this pond is no longer able to overcome the problem of flooding, one of the causes being the capacity of the existing retention pond that is not appropriate and the problem of sedimentation deposits. The research method used was a measurement survey to obtain data on the cross-sectional area and depth of the pond, in addition to taking sediment samples at the inlet, outlet and middle of the pond to carry out filter analysis and specific gravity in the laboratory. The results of the study showed that based on bed load analysis using the Frijlink method, the largest bed load was 5.192 x 10-6 m3 /s/m, the bed load volume was 3.7832 x 10-6 m3 /s and the largest retention pond embankment volume was 25,788.25 m3 /year Kata Kunci : Retention Pond, Sedimentation, Bed load, Embankment volume
