Uji Kinerja Emitter pada Sistem Irigasi Tetes

Drip irrigation can be used to meet crop water needs and save water on dry land in Indonesia which reaches 89 percent. However, the price for one emitter is still quite expensive. To overcome such problem, a study was conducted on the performance of drip type micro irrigation with local-made emitters. By knowing the performance of the drops studied, an efficient alternative drip irrigation technique can be obtained. Performance test using a prototype was carried out at the Hydraulics Laboratory of Balai Irigasi using the observation and the trial and error methods. The results showed the optimal drip uniformity values for the 5 minutes aerator faucet emitter was 76.56% and for 0.2 bar pressure was 72.42%; for the 5 minutes infusion clamp emitter was 87.07% and for 1 bar pressure was 71.01 %; the 5 minutes cable terminal emitter was 67.09% and for 0.2 bar pressure was 84.62%.
