Abstract

This study aims to determine the application of a three-storey drip irrigation system to horticultural crops of chilies, kale and eggplant as one of the household food supporting crop commodities. In addition to increasing the potential for irrigation and boosting the economy from agricultural products on this limited land, it is necessary to know this, so that it can be used as material for consideration in maintaining family food security. Irrigation test activities were also carried out on irrigation uniformity, irrigation distribution and irrigation depth at various irrigation times. Tests were carried out on variations of soil and compost as planting media with the ratios of: 70%: 30%, 50%: 50%, 30%: 70% and four variations in tank water volume. The drip application network uses ½” PVC pipe and dripe on the third floor, while for the first and second levels the Netafim (NTF) pipe is 12 mm. The secondary irrigation network uses ¾ inch, 1 ½ inch and ½ inch PVC in an irrigation test chamber measuring 1.5 m x 4 m and a height of 1 m between levels. The results of the analysis of the test data showed that the uniformity of PVC drip irrigation and NTF combined obtained an average of above 95%, with a very even distribution of water. Irrigation depth obtained at all variations of the water tank level, that is, at 70% of the soil ranges from 3cm -20 cm, at 50% of the soil ranges from 4cm - 20cm and at 30% the amount of infiltration ranges from 2.5 cm - 18.5 cm. Multilevel drip irrigation can support the provision of family food in meeting the needs of kitchen ingredients such as chilies and vegetables to support family food security

Abstract

Perforation irrigation is a unidirectional beam irrigation system that can be used for crop irrigation on dry land, due to the efficient use of water and the ability to wet land with a limited area. Therefore, the perforation irrigation system needs to be studied further in relation to the area of land that can be irrigated and the distribution of discharge to each perforated pipe. By testing several variations of the water level, the perforation irrigation emission capability will be obtained in the form of irrigation distribution, uniformity, emission capability and discharge amount used in irrigation on flat land. This study aims to determine the perforation irrigation capacity on flat land, the distribution of irrigation and the amount of discharge required. The test was carried out on three perforated pipes made of ½” PVC as lateral pipes, three transmission pipe length variations, such as 0.8m, 1m, and 1.2m with a distance between the perforations of 60 cm. The source of irrigation water comes from a 3 m tall tower with a capacity of ± 200 ????????????????????. The test uses three variations of head height, namely h1 350 cm, h2 360 cm, h3 370 cm and h4 380 cm. The results showed that the perforation irrigation jet length was around 100cm -120 cm, the uniformity of CU irrigation was above 97% with a total discharge on h1 QT = 0.689 lt/s, h2 QT = 0.690 lt/s , h3 QT = 0.695 lt/s and on h4 QT = 0.701 lt/s. While the range of flow rates for perforation 1 pipe Q1 (0.42 lt/s – 0.429 lt/s), perforation 2, Q2 (0.13 -0.145 lt/s) and perforation 3, Q3 (0.129 - 0.135 lt/s)
