Abstract

The main purpose of the research is to examine in some depth the problem occurrences fertigation system that use for nowdays. From what we observed there are easy and cost less money transforming. Function of this experiment is to shows the expectation result in input (EC) that needed to reach the output (EC) electrical conductivity of 2.5 μs/cm for the minimum range of 20 holes of micro pipes. This minimum result then can be assume on the next top-up input of the fertilizer in reason for do not want to overdose or undersupply the content of the fertilizer that leads unbalance or unhealthy growth of plant. After that, the content of fertilizer output were tested from 20 to 100 holes to test how much loss was recorded when using venturi injector. This is because when more holes were stamped the suction, the speed of venturi injector increases due to many micro pipe flow out of the water output. Other than that, is to show the outcome in produce more yields crop in such an efficient way and less effort in planning to connect the irrigation system with water timer tools. This product can set the time according to the schedule where it open the valve to allow water flow in for the fertilizer content reaches the plant. Several component that has use in the whole system was design for less cost but in such complex fertigation system and must work efficiently to assure precise result outcome.
