The aim of this research was to evaluate the irrigation consumption for the growth of Kangkong (Ipomoea aquatica Forsk. Var. reptan). The system based on drip irrigation for crops. Drip irrigation system consisted of a 16-liter water tank, a water supply facilities and water supply systems. The water tank is raised 1,000 mm above the ground, connected by a 18 mm (1/2 in) PVC pipe at the conversion head. Drip tape is paying a hole measuring 100 mm. The rate of water distribution is equal to 2.20 liters per hour, consisting of 6 lines. Each line had a distance of 200 mm, according to the plantation. According to the characteristics of the plot, which had 60 wells and provides 25 days of water throughout the harvest of Kangkong. The research found that water consumption of Kangkong average of 108.5 mm or 4.4 millimeters per day. The average height was 334 millimeters per plant. The average weight was 8.96 grams per plant. The average root length was 89.6 mm. Number of leaves was 12 per plant. The average leaf length was 131.3 mm and the average yield of Kangkong throughout the season was 4.93 kg
