Perancangan Sistem Hidroponik Skala Rumah Tangga dengan Metode Bertingkat untuk Tanaman Selada

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.
