Abstract
Saat ini telah banyak dikembangkan sistem irigasi menggunakan tenaga matahari. Hal ini lebih diminati karena memanfaatkan energi alternatif dari alam. Namun penggunaan energi tersebut tidak efektif, karena pada sistem irigasinya masih menggunakan pompa air listrik berpenggerak motor induksi yang membutuhkan arus bolak-balik (AC). Sehingga dibutuhkan inverter untuk mengkonversi tegangan searah (DC) menjadi tegangan AC. Maka pada penelitian telah dilakukan rancang bangun untuk mengontrol laju aliran pompa air berpengerak Brushless DC motor (BLDC). Laju alir pompa air dibuat konstan dengan mengatur kecepatan putar motor BLDC menggunakan kontrol Proportional-Integral-Derivative (PID) yang terdeteksi dari sensor hall-effect. Laju alir pompa air akan terbaca oleh sensor flow rate yang kemudian akan dibandingkan nilainya dengan nilai yang telah ditentukan sebagai nilai setpoint. Sistem ini akan diintegrasikan menggunakan mikrokontroler Arduino Due. Pada hasil pengujian keseluruhan sistem menggunakan PID, apabila diberikan beban berupa putaran kran pada sistem, didapatkan laju aliran air yang stabil dan mendekati nilai setpoint yaitu dengan nilai error minimum 0% dan error maksimum 2.8%, serta rata – rata error nya mencapai 0.9%. Sehingga didapatkan laju aliran air yang konstan mendekati nilai setpoint, ketika putaran motor BLDC telah mencapai keadaan steady. ==================== Nowadays, many irrigation systems have been developed using solar power. This is more desirable because it utilizes alternative energy from nature. But the use of energy is not effective, because the irrigation system is still using an electric water pump which driven induction motors that require alternating current (AC). So it takes an inverter to convert DC voltage into AC voltage. In this research have been made a system to control the flow rate of Brushless DC motorized water pump (BLDC). The flow rate of the water pump is made constant by adjusting the rotation speed of the BLDC motor using Proportional-Integral-Derivative (PID) control from the hall-effect sensor. The flow rate of the water pump will be read by the flow rate sensor then compare its value to the specific value as the set point value. This system will be integrated using Arduino Due. In the test result the whole system using PID, when the load given in the form of tap rotation on the system, obtained a steady flow rate of water and close to the set point value with a minimum error of 0% and maximum error 2.8%, and the average error reaches 0.9%. So that the water flow rate is constant close to the set point value, when the motor rotation of BLDC has reached steady state.
