Abstract

Hydroponic model SWU-01 is a new hydroponic system innovation that regulates watering automatically and independently by utilizing gravity and Archimedes' law. Dissolved oxygen concentration in SWU-01 is only around 3-4.2 mg/L. DO values can be increased by applying nanobubble technology. Ultrafine bubble or nanobubble is a gas bubble in a liquid that has a diameter of <200 nm. The purpose of this study was to determine the effect of nanobubble on dissolved oxygen concentration and growth of lettuce plants cultivated with SWU-01 hydroponics. The experiment used a one-factor randomized complete block design, namely intermittent administration of nanobubble for 15 min every 3 day (P1) and 7 days (P2), and without nanobubble (P0l). The results obtained based on the ANOVA test at the 5% level with the Least Significant Difference (LSD) follow-up test, namely the parameters of fresh weight and number of leaves of lettuce P1 significantly different from P0 and P2, and no significant differences were found in root length, canopy width, and plant height. The P1 treatment is more effective in increasing dissolved oxygen concentration, leaf count, and fresh weight of lettuce produced in lettuce cultivation using the SWU-01 hydroponic system. Keywords: Dissolved oxygen, Hydroponics, Lettuce, Nanobubbles, Plant growth.

Abstract

The three priority issues faced by the Cikandang Agro Farmers Group are 1) the flow of nutrient solution is not smooth due to clogged nozzle holes and the insoluble nutrient solids; 2) the misting flow of the nutrient solution is uneven due to leaks at several points in the nutrient solution distribution pipes; and 3) not all root zones of the plants are reached by the nutrient spray due to the nutrient solution spray not being in the form of fog. The objectives of the activity are 1) to design and to construct a system device for preparing and atomizing nutrient solutions for the production of potato seeds in an aeroponics system; and 2) improve the performance of nutrient solution preparation and atomization system devices for potato seed production aeroponics system. The implementation of activities consists of program socialization, training/technical guidance, application of technology, as well as monitoring and evaluation. The substance of the activity consists of problem and need analysis, design and assembly, as well as operation and performance tests. Success indicators were observed through pre-test and post-test which included domains of the cognitive and psychomotor of participants in mastering the technology of preparation and atomization of nutrient solutions for the production of potato seeds in the aeroponics system. Based on the evaluation through pre-test and post-test, there was an increase in the cognitive domain by 80% and psychomotor domain by 70% of participants in mastering the technological aspects of preparation and atomization of nutrient solutions for the production of potato seeds of the aeroponics system. Technical improvements to the equipment of the nutrient solution preparation and fog system produce a smooth flow of nutrient solution, and the nutrient solution spray is no longer in the form of mist but in the form of a uniform fog and is able to reach the plant root zone.
