ALAT DETEKSI DINI KEMATANGAN OPTIMUM BUAH MANGGA (Mangifera indica) SECARA NON-DESTRUCTIVE BERBASIS TEKNOLOGI LDR (RESEP DEPENDEN CAHAYA)

Abstract

Technology which will be develoved on this study is aimed  to detect the maturity of the optimum mango to reduce the risk of mangoes that decay before the distribution is by utilizing LDR-based color sensor technology (Light Dependent Resistor). Where the principle works that is when given light on the surface of the skin of mango fruit then the light will be reproduced captured by the sensor and pass through the filter then if the same color then the filter will absorb the light. The results obtained that mango detected maturity level using LDR more efficient and accurate where mango has optimum maturity level has an output voltage interval of 150.68 mV - 155.45 mV. Where this technology is expected to increase mango productivity in Indonesia so as to increase exports to other countries that can support the world of agriculture.
