Design of automatic control system on trickle irrigation for tomato cultivation

Abstract

The development of technology has had an impact on the progress of irrigation systems, called the intelligent irrigation system 4.0. The objectives of this research are a measurement of Emission Uniformity (EU) and designing automatic irrigation based on soil water sensors. The result of EU value is in the range of 85-90%, which is a good category. EU value can determine whether one emitter can represent the entire emitter in one irrigation system. The principle of the soil water sensor is to read the value of the soil moisture content in the planting medium. The soil water content of 22.4%, which is the field capacity, is used as an upper limit and the soil water content of 21.1%, which is the critical point, is used as the lower limit. Determination of the critical point value is done by using the management allowable depletion (MAD) value of 0.52. The working principle of the control system is to monitor the work of the soil water sensor and become the main data to control valves, pumps, and dosing. The required cost for the automatic system is Rp. 12,626,000, -.

A Study of Irrigation Management in Smart Farming and IoT for Greenhouse Tomato Production

“…The intricate process of tomato growth requires careful monitoring of soil moisture, temperature, sunlight, and nutrient levels, with irrigation playing a crucial role; consistent watering is essential for optimal plant development and can greatly influence the success and quality of the harvest. Traditionally, farmers have manually monitored soil moisture levels and adjusted irrigation systems during tomato cultivation, but in recent years, the widespread adoption of automated irrigation devices in agriculture has become increasingly prevalent, utilizing sensors and other technologies to automatically monitor soil moisture levels and make necessary adjustments [22], [23].…”

“…Successful tomato cultivation in an smart greenhouse setting requires careful management of environmental variables such as temperature, humidity, and luminosity, wherein sensors and other technologies track these factors in real time, empowering farmers to make educated choices about maximizing crop growth [23]. Tomato plants thrive at warm temperatures, but excessive heat can stunt their development; according to [60] and [61], temperature sensors can be used to fine-tune the atmosphere of an smart greenhouse for optimal plant growth, thus helping maintain a steady temperature for plant development.…”

Aplikasi Irigasi Cerdas di P4S Buana Lestari, Kabupaten Nganjuk, Jawa Timur

“…Melalui penerapan irigasi cerdas, air irigasi diberikan tepat waktu dan tepat jumlah, dengan sistem kendali yang lebih mudah. Dengan demikian, manfaat dari aplikasi irigasi cerdas adalah hemat air, hemat energi, hemat tenaga kerja, dan hemat biaya irigasi, yang diharapkan dapat meningkatkan pendapatan usaha tani (Irwin and Prastowo 2022).…”

“…Untuk mempunyai nilai EU yang tinggi diperlukan desain pipa sub-unit (manifold & lateral) yang benar, yaitu kehilangan head pada sub-unit <20% Ha (Prastowo 2010). Sistem automasi jaringan irigasi tetes hanya akan berjalan dengan efektif dan efisien apabila dipasang pada jaringan irigasi tetes dengan nilai EU yang relatif tinggi (Irwin and Prastowo 2022).…”
