Evalusi Kinerja Jaringan Irigasi Curah (Sprinkler Irrigation) melalui Simulasi Hidrolis menggunakan EPANET 2.0.

Abstract

Sprinkler irrigation network can be a good investment when well designed, installed, maintained and managed. But the calculation manually is time consuming and gives rise to human error. Therefore, this study aims to evaluate the performance of sprinkler irrigation through simulation using software EPANET 2.0 using secondary data is using and data is analysis by using simulation with software EPANET 2.0. This study was conducted on irrigation network in the village of Tenilo, Gorontalo and the villages of Akar-akar, NTB. The simulation resulted the average pressure at both locations excess of the recommended optimum pressure 40 m, but not exceeding the maximum recommended pressure 65 m,the variation pressure on each location is 2.82 m and 9.35 m. Debit issued by sprinkler is also nearing discharge plan 9.11 liters/second. The velocity of the flow both locations is not different much. It’s less than maximum allowable speed 3 m/s, it means that the network is safe from abrasion and water hammer on a pipe. Based on the results of simulation sprinkler irrigation network installed in the village of Tenilo and the villages of Akar-akar have met the criteria of hydraulic limitation in designing a system of sprinkler irrigation.
