Abstract

Quick detection of moisture content and seed viability is very important in seed technology. The use of sound frequency that produced by seed if that seed reflected with another material is one method that haven’t yet researched. The purpose of this research is sound detection to determine moisture content and viability of soybean seeds by looking the sound waves frequency produced. This research consisted of two experiments, the first experiment the effect size of seed and moisture content of the sound frequency. The second experiment the effect size of seed and viability of the frequency. This research was arranged in the randomized completely design was used with twofactorsis size of seed and moisture content (first experiment) and size of seed and viability (second experiment). The results showed that sound detection can used to estimate the moisture content of seed but can’t used to estimate viability of seed. Results showed that sound detection devices can be used to estimate the water content of seeds without seeing the size of the seed, but can’t used to estimate viability of seed. The first experiment had a negative correlation between the frequency and moisture content has a value of correlation (r) 0.95 approach 1 (≈ 1), it meansthe higher water content, the frequencies lower sound produced.
