Abstract
Hidrolika adalah ilmu yang mempelajari perilaku dan pergerakan fluida, terutama air, dalam berbagai kondisi. salah satunya kecepatan aliran, penampang basah, debit aliran, koefisien debit dan energi spesifik yang terdapat pada suatu aliran. Tujuan penelitian ini adalah untuk mengetahui kondisi dari pengaruh ambang lebar terhadap koefisien debit aliran dan energi spesifik minimum yang dihasilkan. Pengumpulan data yang dilakukan adalah mencatat volume (v), waktu (T), tinggi air sebelum ambang lebar dan sesudah ambang lebar pada alat flumetest. Data yang sudah di dapat dari hasil pengujian kemudian dilanjutkan pada tahap analisis data. Analisa data untuk mencari debit aliran. setelah itu di analisa untuk mendapatkan kecepatan aliran, penampang basah, koefisien debit, bilangan froude, energi spesifik dan jenis aliran yang terjadi akibat ambang lebar. Penelitian ambang lebar saluran terbuka menggunakan 10 variasi debit dengan bukaan kran (9°, 18°, 27°, 36°, 45°, 54°,63°, 72°,81°, dan 90°). Dari hasil pembahasan dapat disimpulkan bahwa hubungan debit aliran Q (lt/det) dan Koefisien debit (Cd) pada ambang lebar mempunyai persamaan Q = 0,3487 Cd+ 0,1738 sedangkan hubungan debit aliran Q (lt/det) dan energi spesifik Es (meter) pada ambang lebar mempunyai persamaan Q = 0,108Es2 + 0,2985Es - 0,064. Kata kunci: ambang lebar, koefisien debit, energi spesifik. / Hydraulics is the science that studies the behavior and movement of fluids, especially water, under various conditions. One of them is flow velocity, wet cross-section, flow discharge, discharge coefficient and specific energy contained in a flow. The purpose of this study is to determine the conditions of the influence of the wide threshold on the discharge coefficient of flow and the minimum specific energy produced. The data collection carried out was to record the volume (v), time (T), water height before the width threshold and after the width threshold on the flumetest device. The data that has been obtained from the test results is then continued at the data analysis stage. Analyze the data to find the flow discharge. After that, it is analyzed to obtain the flow velocity, wet cross-section, discharge coefficient, froude number, specific energy and type of flow that occurs due to the wide threshold. The study of the wide threshold of the open channel used 10 variations of discharge with faucet openings (9°, 18°, 27°, 36°, 45°, 54°, 63°, 72°, 81°, and 90°). From the results of the discussion, it can be concluded that the relationship between the flow discharge Q (lt/sec) and the discharge coefficient (Cd) at the width threshold has the equation Q = 0.3487 Cd+ 0.1738 while the flow discharge relationship Q (lt/sec) and the specific energy Es (meters) at the width threshold has the equation Q = 0.108Es2 + 0.2985Es - 0.064. Keywords: wide threshold, discharge coefficient, specific energi.
