AbstractSelf-supporting food, especially rice which has become a problem for a long time in Indonesia should be overcome gradually. Specifically, this research aimed to support self-supporting food by growing plants, especially rice in dry land by using water effectively and efficiently. The use of water effectively and efficiently here means providing water that is not excessively, only in the root zone of the plant. It is in line with the objective of this re-search that is to design a prototype of device that can be used to create artificial rain to irrigate the surface of land and it will be stopped if the water has reached the root zone of the rice plants. The longer the rain given, the deeper the water absorption will be. The research results showed that the longer the rain is given, the deeper the water absorption will be. The result of research with the length of rain for 120 minutes, it needed the average volume of water of 331.83 liters and resulted in the thickness of absorption as follows: Treatment T0 (uncultivated land) the average of absorption was 7.3 cm, T1 (the land was cultivated by hoeing) the average of absorption was 18.09 cm and T2 (the land was cultivated by hoeing and loosening) the average of absorption was 21.3 cm. In details, the research data can be seen in table 1 and 2. The regression analysis of the volume of water and the thickness of water absorption is shown below: Â Treatment T0Â Y = 2.14 + 0.018 X; Treatment T1Â Y = 4.64 + 0.042 X; Treatment T2Â Y = 6.09 â€“ 0.047 X Furthermore, the result of hypothesis testing showed that there is a real difference in the three treatments. It means that with the same need of water volume, there is a significant difference in the thickness of water absorption as shown in the three treatments.
