ABSTRAK Dalam suatu proyek bendungan pasti dibutuhkan perhitungan yang digunakan untuk membantu pembangunan. Perhitungan yang dibuat ini merupakan perhitungan profil aliran dengan metoda integrasi grafis dan metoda tahapan langsung. Tujuan perhitungan profil aliran untuk membantu dalam pembangunan bendungan agar aliran sungai mengalir dengan baik menuju bendung. Tujuan dari pembuatan aplikasi ini untuk mempermudah perhitungan secara manual. Aplikasi yang dibuat ini menggunakan bahasa pemrograman Java dengan database MySQL. Sumber data yang diperoleh dari literatur dan pengujian aplikasi dengan membandingkan perhitungan aplikasi dan perhitungan secara manual. Kata kunci: profil aliran, proyek, aplikasi, data

ABSTRACT In a dam project must be required calculations used to aid development. This calculation is a calculation of the flow profile with a graphical integration method and direct step method. Purposes of calculating the flow profile to assist in the construction of a dam that river flows well into the weir. Purpose of making this application to simplify the calculations manually. This application is created using the Java programming language with MySQL database. Source of data obtained from the literature and application testing by comparing the calculation and application of manual calculations. Keywords: flow profile, projects, applications, data
