Otomatisasi Ultrasonik Fogger Budidaya Selada Keriting Hijau Secara Fogponik di Pertanian Indoor berbasis Internet of Things (IoT)

Abstract

Lettuce or in Indonesia better known as bokor lettuce is a commodity that has bright prospects for cultivation. Green Curly Lettuce is harvested at the age of 25 - 35 days. The price of Green Curly Lettuce on the market can reach Rp. 10,000 to Rp. 15,000 per kg. One of the hydroponic methods that can be carried out for cultivating Green Curly Lettuce plants indoors is a hydroponic system with fog or commonly called Fogponic. Fogponic is a hydroponic system developed from the Aeroponic method, using an ultrasonic fogger or atomizer to atomize nutrients to plant roots. The aims of this research are 1). Designing a water temperature control system device, solution concentration and light height of Fogponic nutrient water in Indoor Agriculture. 2). Create an Automatic Ultrasonic Fogger to maximize nutrition to the roots of Green Curly Lettuce plants. 3), Evaluate the performance of the Automatic Ultrasonic Fogger system by integrating it with the Internet of Things (IoT) via the Thingspeak website. Fogponic design using Ultrasonic Fogger can maximize the little water needed by plants. Even though the use of LED Grow Light cannot replace sunlight in Greenhouses. Automatic Ultrasonic Fogger works according to schedule at 06.00, 08.00, 10.00, 12.00, 14.00, 16.00 and 18.00. Besides that, it will work when the fogging machine detects the water level is decreasing so that it gives a notification to add nutrient water. The Fogponics work system can revive green curly lettuce plants and is better than Deep Water Culture (DWC) Hydroponics. However, it is not significantly different from Bubbleponik and still inferior to simple Aeroponics.
