Abstract

The research objective is to know Pakcoy Cultivation Growth (Brassica rapa L.) on Floating Raft Hydroponic System Using Spray Bars Pumps. This research has been carried out in December 2022 to the month of Mei 2022 at the Greenhouse Agricultural Engineering Study Program, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, Indralaya, South Sumatra. The research method used was designed to modify the floating raft using DFT pipes in the oxygen circulation system using a spray bars type venturi pump. The results showed that the design of spray bars pumps can minimize oxygen deficiency in floating raft pakcoy plants with a DO level value of 4.2 mg / l, plants with the highest average stem was found in L2 which was 25.4 cm. The average number of leaves are the most in L2, which were 16 strands. The longest average root is in L2 which was 42.6 cm. The highest average fresh weight was found at L2 which was 70.2 g.
