Abstract

Province of Lampung is one of the rice producer region, but rice planting in this region often experiences harvest failure caused of water deficit. This problem is caused by many agriculture area still have not irrigation system as found in the village of Sumberrejo, distric of Pringsewu. To suply amount of water needed by plants such as rice, farmers at this village usually expect rain or use pump moved by engine to pump water from Way Limus river that found around agriculture area. One of the solution that can be used to fulfill the water availability is using technology of hydram pump. By using technology of hydram pump, small falling water energy of Way Limus can be used to help farmers to irrigate their agriculture area without using engine or electrical motor. In this paper is presented the activities to build irrigation system using hydram pump. This irrigation system is developed by team together with local society. Based on testing result of performance of the hydram pump model made before, with supply head of 1,5 m and delivery head of 7 m, so diameter and length of supply pipe of hydram pump were chosen 2 in. and 11,3 m. Weight and diameter of waste valve used were 0.32 kg and 4,6 cm respectively, and volume of air chamber was 4.771 cm3. The testing results shown this pump can delivery 4,182 lit/men (6 m3 per day) of water to the height of 7 m. And if 2 pumps were used over 24 hours, total water was pumped 12 m3 per day. So this water can be used to irrigate rice field area about 300 m2, and in application the farmers by turns use this water to irrigate their rice field.
