The response of <i>Dundubia Manifera</i> sound effects to changes in stomata density and stomata index of water spinach as information on the rate of photosynthesis

Sound waves are vibrations that propagate through a medium. can be applied to agricultural land as technology is often called Plant Acoustic Frequency Technology (PAFT). This by using sound has been manipulated with certain frequency. study aims provide the effect of Dundubia Manifera determine on stomatal density and index. Adobe Audition CS6 4000 Hz which will 30 minutes for 28 days. The results show stomata index affected exposure waves. In which, was reduced 89% control plants (97,506 /mm2) treatment (51,428 /mm2). Meanwhile, increased 41% (0.194 m) (0.274 m). These indicate have very good impact such increasing rate photosynthesis, plant immune systems, surviving climate change, crop yields.
