RANCANG BANGUN SISTEM HIDROPONIK PASANG SURUT OTOMATIS UNTUK BUDIDAYA TANAMAN CABAI
ABSTRACT: Ebb and flow
hydroponic system generally used a timer to controlnutrient addition. The use of the timer, howeverhas major
disadvantage including inefficiency of nutrient usage. This research aimed at designing of ebb andflow
automatic hydroponic system which able
to turn on/off the
pump based on the moisture
content usingmicrocontroller.The
research was conducted at Greenhouse Facility of the Integrated Field Lab of
AgricultureSchool, the University
of Lampung from
April - June
2014. The procedure
begins with the
manufacture ofinstrument,
calibration, system design tool, the power supply circuit, equipment test and
field test. The resultsshowed that has
been successfully realized automatic ebb and flow hydroponic system working
based on the moisture content. The value
of setting point obtained for controling water content for turning on the pump
was < 34.95% and turning off the pump was
> 69.83%. Cultivation test
using chilli pepper resulted that automatic ebb and flow hydroponic system was
significally better than manually system one, in terms of plant height and
number of leaves.
