Abstract

The utilization of multilevel drip irrigation needs to be supported by adequate planting media so that the provision of irrigation water is optimal. The planting media used practically uses soil mixed with livestock waste compost and cocopeat in polybags. This test aims to determine the ability of drip irrigation water absorption by the planting media in the form of irrigation depth and soil moisture provision and prediction of irrigation application with a certain duration. The study was conducted on a ½” PVC pipe drip irrigation network with a 2 lt/hour emitter, on a land size of 2 m x 4m x 2m with a water source from PDAM water which is stored in a tank with a capacity of 150 liters and a height of 2.5 m. The test data taken includes data on the distribution of irrigation volume, irrigation depth and soil moisture. The results of the analysis showed that the distribution of drip irrigation depth in cocopeat media ranged from 7.5 cm - 12 cm in 5 minutes, while in rice husks the absorption was around 6.5 cm - 10 cm for the planting media level, with an average Cu of 96% which is very good. The maximum soil moisture that can be provided by four-tiered drip irrigation at a duration of 5 minutes is 30.5% in the early growth phase and at a duration of 10 minutes the average soil moisture is 15%, in the Vegetative phase of plant growth until fruit ripening. So the high irrigation infiltration rate in cocopeat media has the potential to be applied to plants that have long or deep roots, while planting media with rice husks has the potential to be applied to plants with short roots such as vegetables.

Abstract

The secondary pipe network in a multi-level drip irrigation network is a water source that will serve the drip irrigation network at each level. The amount of flow obtained by the drip irrigation network is highly dependent on the available head height from the water source. This study aims to determine the amount of flow discharge produced by the height of the water source head in a four-level drip irrigation pipe network, so that it can be used for optimal design of a multi-level drip irrigation network. Optimization of the irrigation network is reviewed against the amount of deviation of discharge from the primary network to the drip discharge, as the final result of irrigation to the plants. The test was carried out on a 4-level drip irrigation network with a water source height from the reservoir of 3.21m with a capacity of 200 liters. The head variation consists of four types according to the amount of height of the drip irrigation network to the surface of the reservoir water. The main data analyzed are the volume of flow collected, discharge, speed and deviation of discharge or speed. While the presentation of the results is displayed in the form of regression graphs between the two test parameters, so that they can be applied generally. In the secondary pipe, there is an average difference in flow velocity of around 0.05 m/s in each network, with the lowest secondary flow rate deviation obtained at a small head of 0.2 cm3/s between the fourth and third floors, while the highest discharge deviation is obtained on the first and second floor networks, which is around 1.6 cm3/s. Low vt deviation is obtained at a head below 2.3m and the highest occurs at a head above 2.3m. The difference in head in the primary and secondary distribution networks does not have a significant effect on the distribution of drip irrigation flow, if the drip points are more numerous, the deviation is still within reasonable limits.

Abstract

Multilevel drip irrigation is an irrigation method that supports water-saving agricultural activities in limited areas by channeling water through perforated pipes from emitters. An ideal multilevel drip irrigation system can provide the same volume of droplets to plants, so that the distribution of irrigation water and the uniformity of drip irrigation are important factors that need to be considered when using drip irrigation to provide plant irrigation. This research aims to determine the effect of using variations in the diameter of PVC pipes as primary pipes on the distribution of drip irrigation and its uniformity. The primary irrigation network tested for each network to the 1st floor to the 3rd floor consists of ½", ¾" diameter and 1" pipe, while the secondary and lateral drip pipe networks use ½" PVC. The test was carried out on an area of 4 m x 1 m x 1.8 m with a distance between levels of around 0.9 m, with an irrigation water source from a 200 liter tank placed on a tower with a height of 2.5 m.The results of the research show that the discharge produced by the main pipe is different on each floor of the irrigation network, on the 1st floor the discharge is 127.13 cm3/second and on the 3rd floor the discharge is 120.91 cm3/second, while on the 2nd floor the discharge is between the values of the 1st floor discharge. and 3rd floor. Regarding the results of the distribution of drip irrigation water volume, it is known that the average does not show significant differences due to differences in network operations or due to differences in pipe diameters used, where the values for floors 1 to 3 are respectively 68.75 ml, 68 .47ml, 68.19ml. The uniformity of drip irrigation shows results above 94% on all network floors and is considered very good.
