Plant acoustic frequency technology (PAFT) is a technology that utilizes sound waves in the form of frequencies within the audiosonic threshold. The purpose of this study was to test PAFT by using Javanese gamelan music entitled puspawarna on the productivity of vegetative growth in Kailaan (Brassica alboglabra) plant. PAFT exposure time was given to plants during the morning and evening. The frequencies ranged in 3-5 kHz, 7-9 kHz and 11-13 kHz. In addition, sound exposure times were for 1 hour, 2 hours and 3 hours. Based on the statistical analysis, the results indicated that the frequency and sound exposure time had a significant effect on plant wet weight, plant length, and stomata openings. The best frequency for Kailaan plant growth was in 3-5 kHz with the best exposure time of 3 hours. The combination of frequency and sound exposure time resulted in the most optimal stomata openings (stomata diameter at the top of the leaves of 89.19 ~ 93.45 µm and stomata diameter at the bottom of the leaves of 136.69 ~ 140.74 µm) with chlorophyll of 80.86 chlorophyll content index (cci), plant length of 47.33 cm, plant wet weight of 84 g, area of leaves of 207.06 cm², plant height of 9.4 cm, and number of leaves of 11 strands.
