Yanurianto, Danang (2019) Studi Pengaruh Waktu Konsentrasi Terhadap Variasi Panjang Saluran Dan Kemiringan Lahan Pada Saluran Buatan Menggunakan Rainfall Simulator S12-MKII. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui manakah yang paling berpengaruh antara panjang saluran (L) dan kemiringan lahan (S) terhadap waktu konsentasi (Tc). Penelitian ini dilakukan di Laboratorium Hidrologi Jurusan Teknik Pengairan Universitas Brawijaya dengan menggunakan alat Rainfall Simulator S12-MKII sebagai media dalam pengambilan data yang dibutuhkan.Pengambilan data primer dilakukan dengan beberapa variasi panjang dan kemiringan yang berbeda-beda. Pada variasi panjang yaitu 0 cm (tanpa ada saluran/ditutup semua), 40 cm, 80 cm, 120 cm, dan pada kemiringan lahan yaitu sebesar 0%, 0.25%, 0.5% dengan masing-masing dilakukan 2 kali pengulangan. Dalam analisa perhitungan waktu konsentrasi digunakan beberapa rumus sebagai pembanding manakah yang paling mendekati dan sesuai berdasarkan data penelitian di Laboratorium yaitu Rumus Kirpich, Rumus USBR Design Of Small Dams, dan Rumus Izzard. Kemudian dalam menentukan besarnya pengaruh antara panjang saluran (L) dan kemiringan lahan (S) digunakan metode Analisis Regresi Linear dan Analisis Regresi Non Linear Eksponensial. Berdasarkan hasil dari analisa waktu konsentrasi (Tc) tersebut diketahui bahwa Rumus USBR Design Of Small Dams pada obserasi 1 menggunakan analisis regresi linearlah yang paling sesuai dengan penelitian ini, nilai R2 sama dengan 0,977 dimana nilai tersebut jika mendekati 1 maka nilainya semakin bagus dan dinyatakan memiliki keterikatan yang sangat erat. Dapat diambil kesimpulan bahwa panjang saluran (L) menggunakan analisis regresi linear sederhana yang paling berpengaruh terhadap waktu konsentrasi (Tc) daripada kemiringan lahan (S).
English Abstract
This study aims to find out which is the most influential between channel length (L) and slope of land (S) with respect to concentration time (Tc). This research was conducted at the Hydrological Laboratory of the Department of Irrigation Engineering, University of Brawijaya by using the Rainfall Simulator S12-MKII tool as a medium for retrieving the data needed. Primary data retrieval is done with several different variations in length and slope. In long variations, namely 0 cm (without any channels / closed all), 40 cm, 80 cm, 120 cm, and on the slope of the land that is equal to 0%, 0.25%, 0.5% with each repeated 2 times. In the analysis of the calculation of concentration time, several formulas are used to compare which are the closest and appropriate based on research data in the Laboratory, namely Kirpich Formula, USBR Design Of Small Dams Formula, and Izzard Formula. Then in determining the magnitude of the influence between the channel length (L) and the slope of the land (S) used the Linear Regression Analysis method and Non Linear Regression Analysis. Based on the results of the analysis of concentration time (Tc) it is known that the USBR Design of Small Dams formula in observation 1 uses linear regression analysis that best fits this research, R2 value is 0.977 where the value is close to 1 the value is better and stated to have very close attachment. t can be concluded that the channel length (L) uses simple linear regression analysis that has the most influence on concentration time (Tc) rather than slope (S).
