Abstract
Permukaan bumi akan selalu mengalami fenomena erosi, di satu tempat akan terjadi erosi sementara di tempat lain akan terjadi sedimentasi, sehingga bentuknya akan selalu berubah seiring waktu. Penelitian ini melibatkan simulasi hujan buatan disertai pengaruh arah angin berupa blower NRT-PRO pada sisi kiri dan sisi kanan menggunakan alat rainfall simulator dengan sampel tanah berupa pasir kuarsa. Penggunaan alat rainfall simulator dalam analisis ini memungkinkan simulasi hujan pada skala intensitas 1 liter/menit, 1,5 liter/menit, dan 2 liter/menit. Penelitian menggunakan alat rainfall simulator untuk menguji seberapa besar pengaruh erosivitas hujan yang disertai arah dan kecepatan angin terhadap besaran erosi yang dihasilkan oleh pasir kuarsa. Pada penelitian ini dilakukan analisis perbandingan hasil laju erosi metode USLE (Universal Soil Loss Equation), laju erosi rainfall simulator, dan laju erosi hasil luasan grid rainfall simulator. Hasil dari masing masing pendekatan tersebut memperoleh estimasi besaran laju erosi. Dari analisis dan perhitungan menunjukkan nilai laju erosi menggunakan metode USLE, laju erosi rainfall simulator, dan laju erosi grid rainfall simulator memeroleh hasil yang selaras pada masing masing metode.
English Abstract
The surface of the earth will always experience erosion phenomena, in one place erosion will occur while in another place sedimentation will occur, so that its shape will always change over time. This research involves simulating artificial rain accompanied by the influence of wind direction in the form of NRT-PRO blowers on the left and right sides using a rainfall simulator with soil samples in the form of quartz sand. The use of a rainfall simulator in this analysis allows simulating rain on an intensity scale of 1 liter/minute, 1.5 liters/minute, and 2 liters/minute. The research used a rainfall simulator to test how much influence the erosivity of rain along with wind direction and speed has on the amount of erosion produced by quartz sand. In this study, a comparative analysis was carried out on the erosion rate results of the USLE (Universal Soil Loss Equation) method, the rainfall simulator erosion rate, and the erosion rate resulting from the rainfall simulator grid area. The results of each of these approaches obtain an estimate of the erosion rate. The analysis and calculations show that the erosion rate values using the USLE method, the rainfall simulator erosion rate, and the rainfall simulator grid erosion rate obtained similar results in each method.
