Performance test of emitters made from sago midribs in drip irrigation systems

Abstract

Abstract Increasing water use efficiency can be done by using the right irrigation system according to the needs of the plants. One option for efficient water supply is a drip irrigation system. The research aims to obtain conditions with high drip uniformity values. The study was conducted by testing the level of drip uniformity at several water source head pressures conducted with three replications. The indicator of uniformity is based on the coefficient of variance. The test results show that the uniformity value is higher at lower pressures than at higher heads. The uniformity value indicated by the coefficient of friction at high head pressure for the end and the middle section is better than the lower head pressure. The test results for the middle samples with heads of 19 cm, 62 cm, and 113 cm were 44.92, 23.40, and 9.16, respectively, while for the end samples with heads of 30 cm, 66 cm, and 115 cm were 46.39, 14.43 and 10.36, respectively. These values indicate that the relationship between head pressure and coefficient of variation is inversely proportional. The low coefficient of variation means that the water distribution is evenly distributed. So it can be said that using sago midrib material is feasible as an emitter. In addition, the resulting discharge value is small, so it qualifies as an emitter.
