Venturimeter Booster Design In Irrigation Fertigation System Drops

Abstract

The use of a venturimeter in a drip irrigation fertigation system is very helpful in the plant cultivation process. Apart from being effective and more efficient, providing nutrients to plants directly mixed with water media will facilitate the absorption of these nutrients. Fertilization in drip irrigation systems has obstacles, namely frequent clogging or crusting in the emitter, this is caused by the chemical solution flowing through a series of pipes that are not completely finished. Chemical nutrient solutions that are not smooth can cause the emitter to become easily clogged. The use of a venturimeter in the fertigation system or fertilization in the drip irrigation system is expected to help the homogeneity of the solution and the distribution of nutrients that are complete and not left in the hose, thereby reducing the risk of clogging the chemical solution in the emitter. The use of an appropriate venturimeter will facilitate the maintenance of the drip irrigation system series so that fertigation runs smoothly and precisely according to plant needs. The tools used in this study include grinders, hand drills, nipples, 1 inch HDPE hoses, 5 mm HDPE hoses, emitters, drip sticks, sandpaper, meters, manometers, 1 inch filters, 1 inch venturimers, scissors, measuring cups, drill bits, nails, 10 bar pressure gauges , flow controllers , sandpaper, manual saws, water pumps, NPK sensors. The materials used in this study were 1 inch PVC pipe, T pipe connector, L pipe connector, nutrient solution container, polyethylene (PE) plastic hose, pipe glue, stop valve, wooden batten, wooden rafters, PVC glue, red chili seeds, mulch, NPK, KNO3, SP36, manure, humic acid, trichoderma. The results showed that the average ventrumeter discharge was largest at valve opening 4 with an average of 695 ml / minute. The average venturimeter pressure was largest at valve opening 4 of 1.7 bar. The highest average output solubility level was obtained at valve opening 4 with a value of 590ppm. The larger the valve opening, the greater the discharge and nutrient solubility level.
