Abstract
The increment of urban infrastructure development causes the green land as a catchment area changes into watertight land cover, so the surface runoff increases. When the surface runoff more than the infiltration, its causes floods. One of the solutions is reduce the quantity of watertight land by using the eco-friendly land cover. Besides land cover, land slope is one of the factors affecting amount of surface flow. Therefore, this study was conducted to determine the effect of land cover use and slope relation to surface flow discharge with rain intensity 70 mm / hour. This research was conducted in laboratory using rainfall simulator with area 2 x 1 m and slope variation 0%, 1%, 2%, 3%. Types of land cover used in this research are paving block (stretcher and basketwave pattern), grass block, grass (Pennisetum purpureum schamach), concrete pavement and sand (as land without cover). The results of this study indicate the use of concrete pavement to produce surface flow discharge value ranged from 2.66 to 3.22 liters / minute, paving block of stretcherbond ranged from 2.43 to 3.0 liters / minute, paving block basketwave ranged from 2.17 to 2.72 liters / minute, grass block ranged from 1.99 to 2.59 liters / minute. Grass produced surface flow discharge ranging from 1.40 to 2.12 liters / minute and sand as land without cover ranged from 1.48 to 2.29 liters / minute. The land slope variation is very influential on the amount of surface runoff discharge. The steeper land, make the surface runoff discharge increase.

Summary
Pertumbuhan penduduk di kota Palembang memicu bertambahnya kebutuhan infrastruktur di perkotaan. Sehubungan dengan uraian tersebut, maka dilakukan penelitian yang berjudul pengaruh variasi kemiringan dan tutupan lahan terhadap debit aliran permukaan menggunakan rainfall simulator. Hasil penelitian ini diharapkan dapat menunjukkan jenis tutupan lahan berwawasan lingkungan yang memiliki kemampuan terbesar dalam mengurangi debit aliran permukaan. Hasil penelitian menunjukkan bahwa penggunaan paving dapat mereduksi aliran permukaan 40% hingga 67% untuk setiap jenis paving memiliki kemampuan mereduksi yang berbeda dan tingkat besarnya infiltrasi dipengaruhi dari besarnya spasi yang dihasilkan dari pemasangan paving dapat dilihat pada penelitian. Untuk mendapatkan hasil yang lebih optimal, diambil beberapa parameter dalam penelitian yang berjudul pengaruh variasi kemiringan dan tutupan lahan terhadap debit aliran permukaan menggunakan rainfall simulator. Melanjutkan penelitan Sedyowati dan Susanti maka penelitian pengaruh penggunaan paving block terhadap laju aliran permukaan menggunakan intensitas hujan sebesar 70 mm/jam. Studi ini bertujuan untuk menganalisis pengaruh penutup lahan terhadap debit aliran permukaan dan pengaruh kemiringan lahan terhadap debit aliran permukaan
