Abstract

Agriculture in the dry land of Gumantar, is currently supported by deep groundwater irrigation with a pipe network and outlet box system, but the irrigation method uses a temporary flooding method such as for 2 hours since the pump is turned on. Considering that the irrigation is still very wasteful of water and many areas with small areas have the potential for water supply from the JIAT network to be excessive for the needs of a small area of ​​land. To increase its efficiency, it is necessary to implement another irrigation system, which is more efficient, such as a small sprinkler irrigation system with a short reach, so that it is effective in serving irrigation on small agricultural land and the duration of irrigation can be adjusted to the growth phases of the plants planted, and adjust to the pump capacity. This test was carried out on a land area of ​​about 4 are with a small 24D Netafim sprinkler irrigation system of 10 points and tested in turns every 5 sprinklers with a duration of 1 hour. The test was carried out on the irrigation radius, irrigation depth and irrigation duration. The results of the study showed that for 1 hour irrigation can provide irrigation up to a depth of 7 cm and for a duration of 2 hours it is estimated to be able to provide irrigation up to a depth of 14 cm. The irrigation system at the potential location is used for the provision of water for plants with short plant roots, such as horticulture.

Abstract

Agricultural practices in drylands need to be continuously encouraged so that communities can utilize existing efficient irrigation technology. Irrigation tests on perforated pipe networks need to be conducted to test the distribution of secondary discharge due to the addition of pipe length in the lateral network of the perforated irrigation system. The test was conducted to determine the ability of the irrigation system to provide flow discharge in the primary and secondary pipe networks and the approach to calculating the perforated discharge network. The irrigation test was conducted on three lateral perforated pipe networks with a diameter of ½” and a perforation hole distance of 0.6m, a water tower with a capacity of 200 liters and a height of 4 meters. The perforated flow discharge was analyzed using basic data in the form of head and network design, the results of the analysis were presented in graphs and tables. The results showed that the secondary network flow rates decreased as the network moved further from the water source. An average increase in flow rate of 0.004 l/s was observed for each 0.1 m increase in head. The distribution of secondary flow rates, with variations in pipe length every 60 cm from hole 1 to 6, resulted in decreasing flow rates. In secondary network 1, the flow rate was 0.301 l/s–0.239 l/s, in secondary network 2, the flow rate was 0.276 l/s–0.226 l/s, and in secondary network 3, the flow rate was 0.267 l/s–0.221 l/s. The difference in secondary flow rates across pipe holes 1 to 6 obtained in secondary 1 was 0.06 l/s, in secondary 2 was 0.052 l/s, and in secondary 3 was approximately 0.049 l/s.
