The results showed the chemical properties of the soil showed that there were differences in the chemical properties of each treatment. Soil chemical properties in Rorak treatment had higher levels of Nitrogen (0.50%), Phosphorus (7.33 ppm), Potassium (0.42 me/100 g), and C-organic (4.1 %) than treatment without Rorak Nitrogen (0.16 %), Phosphor (7.18 ppm), Potassium (0.24 me/100 g), C-Organic (2.3%). Making a Rorak with a length of 1.50 m, a width of 1.00 m in 0.40 m, the capacity of which is 0.60 m3, the water in the rorak will run out in an average of 1.96 hours with an average water infiltration rate 0.32 m3/hour. The optimal amount of Rorak/ha is 336 because it has an available water volume of 201.60 m3/ha/day. This amount can meet the water needs of coffee plants, which is 180 m3/ha/day.
