Abstract
Berbagai metode penghitungan sedimen tersedia termasuk metode USLE dan MUSLE yang dirancang atau ditemukan dalam observasi lapangan. Untuk Metode MUSLE, penting untuk mengetahui laju aliran puncak dan volume limpasan permukaan. Data ini sangat penting apabila kita melakukan identifikasi wilayah yang rentan terhadap erosi dan untuk mencegah erosi. Namun di lapangan, perhitungan seringkali disesuaikan dengan data dan parameter yang tersedia. Penelitian ini membandingkan hasil perhitungan debit aliran puncak dan volume limpasan permukaan antara Metode Rasional dan Metode SCS dengan pengamatan di laboratorium, serta kesesuaian Metode USLE dan MUSLE dengan pengamatan sedimen di laboratorium. Percobaan di laboratorium menggunakan simulator hujan dengan intensitas 1 liter/menit, 1,5 liter/menit, dan 2 liter/menit, serta kemiringan lahan maksimal 5%. Hasil penelitian menunjukkan bahwa perhitungan debit aliran puncak dan volume limpasan permukaan menggunakan Metode Rasional lebih mendekati kondisi laboratorium dibandingkan Metode SCS. Namun kedua metode ini dinilai kurang sesuai untuk observasi laboratorium karena hasil perhitungan validasi dan kesalahan relatif menunjukkan ketidaksesuaian dengan performa model. Sedangkan untuk perhitungan sedimen, metode USLE dinilai lebih sesuai dibandingkan metode MUSLE karena metode MUSLE memerlukan analisis penyesuaian agar lebih sesuai untuk observasi laboratorium.
English Abstract
Various sediment calculation methods are available, including the USLE and MUSLE methods which were designed or discovered in field observations. For the MUSLE Method, it is important to know the peak flow rate and surface runoff volume. This data is very important for identifying areas that are vulnerable to erosion and for preventing erosion. However, in the field, calculations are often adjusted to the available data and parameters. This research compares the calculation results of peak flow discharge and surface runoff volume between the Rational Method and the SCS Method with laboratory observations, as well as the suitability of the USLE and MUSLE Methods with laboratory sediment observations. Laboratory experiments use a rain simulator with an intensity of 1 litre/minute, 1.5 litres/minute, and 2 litres/minute, and a maximum land slope of 5%. The research results show that the calculation of peak flow discharge and surface runoff volume using the Rational Method is closer to laboratory conditions than the SCS Method. However, these two methods are considered unsuitable for laboratory observations because the results of validation calculations and relative errors show a mismatch with model performance. Meanwhile, for sediment calculations, the USLE method is considered more suitable than the MUSLE method because the MUSLE method requires adjustment analysis to make it more suitable for laboratory observations.
