ABSTRACT

Hydroponics is a way of farming without using soil as a medium for plant

growing. Nowadays there are various models of hydroponic planting using various kinds

of planting medium. In households with dense of routines it becomes an obstacle to

getting and catering the needs of organic lettuce. So this thesis realized a hydroponic

system with multilevel method.

Broadly speaking, the designed tool consists of planting medium with length 33

cm, width 21,5cm and height 35 cm and connect with water tank with length 18,5cm,

width 13cm, and height 11,5cm and a box with length 8cm, width 4,7cm and height

11,8cm. All processes which affect on lettuce growth and development are water level

which settings with ultrasonic sensor, water filling, nutrient feeding, stirring, and spraying

with temperature sensor as a reference are controlled by arduino mega 2560 as a data

processing center.

From the tests performed, ultrasonic sensor tests which is compared with ruler has

0.6cm largest difference. For temperature sensor tests which is compared with mercury

thermometer has 1°C largest difference. And for planting 24 lettuce test, all of lettuce can

grow and evolve until ready to be harvested.
