Abstract

Bangunan air berperan penting dalam menunjang produktivitas sektor pertanian atau persawahan. Penelitian ini bertujuan untuk menguji pengaruh ambang pada debit air pada saluran terbuka. Jenis ambang yang diuji adalah ambang lebar atau persegi panjang lalu dilakukan eksperimen dengan tinggi bukaan hilir yang berbeda-beda, yaitu 0,5 cm, 1 cm, dan 1,5 cm. Debit air diukur menggunakan flume, dengan dan tanpa ambang. Penelitian dilaksanakan di Laboratorium Teknik Sipil, Universitas Kadiri. Hasil penelitian menunjukkan bahwa adanya ambang pada flume mengakibatkan penurunan debit air yang cukup signifikan. Pada ambang bukaan hilir 0,5 cm, diperoleh debit pada flume tanpa ambang sebesar 0,147 m3/detik, sedangkan debit pada flume dengan ambang hanya sebesar 0,03 m3/detik. Pada ambang bukaan hilir 1 cm dan 1,5 cm, penurunan debit air juga terjadi, yaitu sebesar 0,253 m3/detik menjadi 0,03 m3/detik, dan 0,245 m3/detik menjadi 0,027 m3/detik, secara berurutan. Dengan hasil tersebut, menunjukkan bahwa adanya bendung secara efektif dapat mengatur saluran air dalam sektor pertanian atau persawahan. Penelitian ini juga memberikan informasi yang berguna dalam perencanaan dan perbaikan infrastruktur irigasi dan pengelolaan air yang berkelanjutan.

Abstract

This research aims to evaluate the bearing capacity of the soil in Kates Village, Kauman District, Tulungagung Regency, as a subgrade in flexible pavement through California Bearing Ratio (CBR) testing in the Civil Engineering Laboratory of Kadiri University. The tests were conducted with 56, 25, and 10 blows to determine their impact on the soil's density, strength, and stability. The results showed that soil with 56 blows had the highest CBR value of 28.660% at a 5.08 mm penetration, indicating excellent bearing capacity. The soil with 25 blows showed a CBR value of 17.060%, which is quite high, ensuring adequate stability and bearing capacity. Conversely, the soil with 10 blows had the lowest CBR value of 4.094%, indicating the need for additional compaction before being used in road construction. This research confirms that the number of blows has a significant impact on soil quality, with more intensive compaction improving the soil's density and stability. The final design CBR value obtained was 16%, leading to the conclusion that the soil in this area can be used as a subgrade for flexible pavement.
