Development of controlled drip irrigation with lock time system

Abstract

The utilization of controlled systems in drip irrigation can increase land productivity and can minimize water usage in the dry season. This irrigation system can reduce water loss and can increase the effectiveness and efficiency of agricultural activity. The purposes of this study were to develop and to analyze the ability of controlled drip irrigation with lock time system for watering crops on time and according to the needs. The research method of this study was research and development (R & D) method, starting from designing a control system, prototyping, functional testing, field testing, and data analysis. Based on the test results, the controlled drip irrigation system that had been developed had high time accuracy, with an error percentage of 0.9%. The response of the solenoid valve function had high sensitivity, with an R2 value of 0.99%. This system had high spray consistency with an average spraying error rate of 1.3 ml per emitter. Based on these results, it can be concluded that the controlled drip irrigation device with a lock time system that had been developed can function properly and is suitable for watering crops on time and according to crop needs.
