| Abtrak (Bhs. Inggris) | The citronella plant (Cymbopogon nardus L.) is one of the plants that is able to grow on fertile land and marginal land with low physical, chemical and biological soil quality. A proper irrigation system is needed to increase crop productivity on marginal land. Drip irrigation system automation has the potential to be developed with soil moisture sensors because they are low pressure and efficient. This research aims to: 1) Develop an automatic drip irrigation system based on soil moisture for cultivating citronella plants. 2) Obtain a calibration model for the soil moisture sensor. 3) Testing the performance of an automatic drip irrigation system based on soil moisture in cultivating citronella plants. 4) Identify the growth response of citronella plants. In this research, irrigation water turns on automatically according to commands from the microcontroller based on 2 specified setting points, setting point A of 22–27% and setting point B of 30–35%. The calibration carried out between soil water content and sensor resistance produces a graph with the equation y = -20.448x + 74.755 where the value of R2 = 0.9141. The uniformity coefficient obtained was 94.10%. From the comparison and results of the water pump ignition error based on soil moisture using the APE (Absolute Percentage Error) formula, the MAPE (Mean Absolute Percentage Error) value at setpoint A was 1.93% and 1.64% at setpoint B. This value was obtained from soil moisture data. taken 14–87 HST. The productivity of citronella plants at setpoint A has more optimal results than setpoint B with an average height of 66.83 cm; average number of stems 24.33 stems; average number of leaves 83.67 pieces; and the average stem diameter is 8.12 mm. |
