| dc.description.abstract | This research conducted to designed, implemented, and tested an automatic rain pipe fertigation system using
temperature and soil moisture sensors. The system applied to three irrigation treatments, namely manual
fertilization, semi-manual fertilization, and automatic fertigation. The automatic fertigation actuator setting
point is at temperature of 31 ° C and humidity of 60% to turn on the water pump and nutrient pump then
the water pump will shut down when the temperature value of 25 °C and humidity of 80%. The results showed
a significant difference in the use of irrigation water based on variance test results with an error value of 5%. The
use of water from automatic fertigation is 12.770 ml or 65.9% more efficient than manual irrigation with the
same growth in plant height. The height of oil palm plants in the main nursery with automatic fertigation is
higher on days 7 to 12. Automatic fertilization requires a fertilizer of 1.8 tons per ha, less than manual fertilization
which reaches 3 tons per ha | en_US |
