Abstract

Irrigation required a good efficiency for the design system to ensure that crops receive a good water distribution. Agricultural sector usually used lots of water in order to gain maximum production of crop yield compare to other sectors. The problem occurs when they plant crop in large area or not flat topographic. But for planting crop under solar PV the temperature and sunlight receive are different compare planting at open space or under shade. Also, the height of panel PV is 1.5m and cannot use sprinkler system to deliver water. Thus, there will be different of water consumption needed and the system might not be run efficiently. To solve this problem, drip system is being used. This is because the crop being planted under the solar PV and the water distribute directly to crop root. This system can reduce water consumption. A design of irrigation system for Orthosiphon Stamineus had been calculated from the beginning of system. It consists of the surface water, pump, mainline pipe, lateral pipes, filter (if needed) and several emitters. The design using a drip system to irrigate 4 plots provided an acceptable basis of proper water scheduling, evaluation of the system and minimizing water waste. It was designed for one specific crop which is Orthosiphon Stamineus and considered with irrigation interval of 2 days. The result show that system design capacity, Qs is 15.88L//min. The pump required for the operation of the system is approximately 1Hp which is enough to supply adequate water the crop. The design was trying to fit all the specification of drip system.
