Perencanaan Sistem Kendali Otomatis pada Irigasi Tetes untuk Budidaya Tomat

Abstract

The development of technology has an impact on the progress of the irrigation system, namely the intelligent irrigation system 4.0. The objectives of this research are: analysis of trickle irrigation network performance, analysis of irrigation scheduling, planning of automatic irrigation control systems, and calculation of automatic control system irrigation costs. The performance of the built trickle irrigation network is in the good category with a dropper variation coefficient value of 0.0338, emission uniformity of 87.19%, and irrigation distribution efficiency of 87.19%. The amount of irrigation water supply varied between 2.75 mm – 4.55 mm per application at intervals of 1-3 days. The working principle of the sensor is to read the value of the soil moisture content in the planting medium. The upper limit is a point when the field capacity is 22.4%, while the lower limit is a critical point of 21.1%. Determination of the critical point value is done by using management allowable deficit (MAD) value of 0.52. The working principle of the control system is to monitor the work of the water content sensor and become the main control for opening valves, pumps, and dosing. The required fee is 12,626,000,-.
