Abstract

Seiring dengan berkembangnya zaman, semakin bertambah jumlah penduduk pada suatu kawasan permukiman. Dengan banyaknya bangunan serta gedung-gedung bertingkat meyebabkan wilayah resapan air menjadi berkurang, sehingga dapat menimbulkan berbagai masalah, permasalahan tidak hanya pada sumber resapan air, namun sistem pembuangan air yang buruk juga menjadi penyebab utama sering terjadinya genangan air pada beberapa ruas jalan di Kota Malang, terutama pada ruas Jalan Simpang Gajayana. Untuk mengatasi permasalah tersebut maka perlu adanya evaluasi terkait perencanaan saluran baru dengan tujuan agar air tidak menggenangi permukaan perkerasan jalan. Penalitian ini bertujuan untuk mengetahui kondisi eksisting saluran drainase, desain dimensi saluran drainase dan efisiensi saluran. Dalam penelitian ini pertama-tama dilakukan pengumpulan data berupa data primer dan sekunder, kemudian dilakukan analisis data seperti analisis hidrologi, hidrolika dan efisiensi saluran. Dari hasil analisis dan perhitungan didapatkan Qr5 th =0,028 – 0,209 m3/dt, Qr10 th =0,029 – 0,222 m3/dt, dimensi saluran baru SG 4 KR sepanjang 74 m direncanakan dengan ukuran 60 x 60 cm, SG 7 KR dengan sepanjang saluran 131 m direncanakan dengan ukuran 40 x 40 cm dan saluran SG 3 KN dengan panjang saluran 75 m direncanakan dimensi saluran dengan ukuran 60 x 60 cm. Dari hasil perhitungan yang dilakukan didapatkan bahwa sebelum adanya saluran pada SG 4 KR,SG 7 KR dan SG 3 KN sebanyak 6 saluran pada ruas Jalan Simpang Gajayana tidak efisien dan hanya 2 saluran yang efisien, setelah dilakukan evaluasi saluran dan pembuatan saluran baru maka seluruh yang ada dinyatakan efisien dalam membuang air didalam saluran.
