Abstract


Abstract

Control of soil moisture can save water supply for crops. The soil moisture sensor integrated with the Arduino microcontroller board can be programmed as the control system. Addition of RTC module and SD module tools also make the system as the data logger. The purpose of this research was to developed the irrigation automation system with the control of soil moisture. This system has been integrated with the automation system using the power source of solar energy. Soil texture is sandy clay loam, which is dominated by the sand content of 59.67%. Rainfall during the study was 58.5 mm. The control system with Arduino board, set to keep soil moisture between 0.23 cm3cm-3 - 0.30 cm3cm-3. The soil moisture in that range was able to be controlled with this system. Land without agricultural cultivation activities when water resources are limited, can be empowered with the application of irrigation automation systems.

Abstrak

Pengendalian kelembaban tanah dapat menghemat pasokan air untuk tanaman. Sensor kelembaban tanah yang diintegrasikan dengan papan mikrokontroler Arduino dapat diprogram sebagai sistem pengendalian tersebut. Penambahan alat RTC module dan SD module juga menjadikan sistem sebagai data logger. Tujuan dari penelitian ini adalah untuk mengembangkan sistem otomatisasi irigasi dengan kendali kelembaban tanah. Sistem ini terintegrasi dengan sistem otomatisasi menggunakan sumber tenaga dari energi surya. Tekstur tanah adalah lempung liat berpasir, yang didominasi oleh kandungan pasir sebesar 59.67%. Curah hujan selama penelitian adalah 58.5 mm. Sistem kontrol dengan papan Arduino, diatur untuk menjaga kelembaban tanah antara 0.23 cm3cm-3 – 0.30 cm3cm-3. Kelembaban tanah pada kisaran tersebut mampu dikontrol dengan sistem ini. Lahan tanpa kegiatan budidaya pertanian pada saat sumber daya air terbatas, dapat diberdayakan dengan aplikasi sistem otomatisasi irigasi.
