Abstract

Porous irrigation is an irrigation system that uses small pipes, hoses, and sprayers to distribute water slowly and evenly to plants. This study aims to determine the water distribution test of the porous emitter irrigation system at various watering times on the physical properties of ultisol soil in swamp land. The method carried out in this study is a descriptive method and by collecting data in the field directly or direct observation (observation). The research parameters in this study are temperature and humidity, water discharge and water volume, soil moisture content, soil wetting patterns, infiltration, percolation, distribution patterns, and soil physical properties consisting of bulk density, porosity and soil hydraulic conductivity. The measurement results in this study are the highest temperature at M4, while the lowest is at M3. The water discharge is measured for 2 minutes with a volume of 200 ml, the greater the water pressure, the greater the volume obtained. The highest moisture content was found in M3 (mixture of ultisol and cocopeat) at 97.01%, while the lowest was found in M1 (ultisol soil without mixture) at 90.71%. The average wetting was highest on B8 on the third day (3.9 cm), lowest on B2 on the first day (3.0 cm). The highest water drop occurred on M4, lowest on M1 for 2 and 3 minutes. At 2 minutes, M3 had the lowest groundwater weight (1.3 grams) and the highest M1 (1,725 grams). At 3 minutes, the lowest M3 (2.25 grams) and the highest M2 (2.575 grams). The M1 Water Distribution pattern shows the best water distribution. The average bulk density was 0.52 gr/cm³, with the lowest pore space of 0.77% and the highest 0.83%. The highest value of soil hydraulic conductivity is on M4, lowest on M1.
