Plant photosynthesis is strongly influenced by light, carbon dioxide, the availability of water and nutrients found in the soil. In this study, LED light combined with gambelan music Gong Kebyar was applied to pakcoy plants to see its effect on growth and productivity. The LED light that is applied is white, red-blue, and red-white-blue LED light, which is given for 20 hours from 06.00 to 02.00. Gambelan Gong Kebyar music is applied for 3 hours, from 06.00 to 12.00. Variables observed included plant height, canopy area, leaf greenery, root length, and plant biomass. The results showed that white LED light had a negative effect, while the red-blue LED, and red-white-blue light had a positive effect on the growth and productivity of Pakcoy mustard. The use of red-blue LED light with a wavelength range of 450-760 nm, combined with gong kebyar gamelan music gave the highest value on plant height (27,176 cm), canopy area (1457.59 cm2), leaf greenery (160.03), root length (23.6 cm), canopy and root wet weight (91.68 g and 5.26 g) and plant and root biomass (4.63 g and 0.42 g). It can be concluded that the use of red blue LED light combined with gong kebyar gamelan music increases the growth and productivity of pakcoy mustard.
