Abstract
Being a non-destructive was of analyzing internal characteristics of agricultural products, acoustic response method had been used as a tool in maturity detection of watermelons. In this study, impulse sound signals were collected by thumping the watermelon on three points: top, center, and bottom. Sound analysis on these signals was done to identify the frequency response of each watermelon. Sweetness at each point was obtained and used as the basis for maturity of watermelons. A classification model was then established by correlating the frequency response with sweetness. Based on this, an Android-based mobile application that can determine watermelon maturity from frequency response was developed by evaluating sweetness. Testing results showed that the developed Android application could determine watermelon sweetness at 85.90% accuracy.
