| Summary: | : Sound exposure to seed germination is an attempt to increase germination, growth in stem length and sprout width. This study aims to determine the effect of amplitude (Sound Level) on the germination of cherry tomato seeds, to know the best amplitude Single Tone for the efficiency of germination of cherry tomato seeds and to compile the results of research as a source of learning on growth and growth material in plants in the form of Student WorkSheets. The research design using Completely Randomized Design, with 5 treatments and 4 replications. The treatment is Single Tone amplitude / volume (decibel / dB) variation consisting of P0 (without sound), P1 (65 dB), P2 (75 dB), P3 (85 dB) and P4 (95 dB). The results showed that the amplitude Single Tone significantly affected the growth of stem length and leaf width (P> 0,05). The best treatment is P3 with amplitude 85 dB which produces average germination rate, the growth of stem length and leaf width of 99%, 5.84 cm and 0.29 cm, respectively, whereas the lowest treatment on without sound (P0) 91% for germination, and 0.23 cm for leaf width. As well as on P4 (95 dB) of 4.90 cm for the length of cherry tomato sprout stems. Research results can be developed as learning resources in the form of Student WorkSheets.
