Modifikasi dan Uji Alat Monitoring dengan Pengontrol Ppm Otomatis pada Pertanian Hidroponik Tanaman Pakcoy (Brassica Rapa L.)

Abstract

Microcontroller based nutrient pumping system design needs to be applied to agriculture. The main of the research was to test the accurate pumping duration delivering the nutrition on Pakcoy plantation hydroponic (Brassica rapa L.) using the Automatic PPM Controlling tool by managing the pumping nutrition duration of the tool. The research used non complete factorial random design. The results of the research were the best pumping nutrition duration, the growth of the plantation which was 7,5 cm and the good quantities of leaves that averagely having 7 leaves each on 25 second [P3]. The wet weight was also on the pumping nutrition duration 25 second [P3] was 32,8467 grams. The biggest amount of net weight was on the pumping nutrition duration 25 second [P3] was 2,42 grams.
