SISTEM DETEKSI KEMATANGAN BUAH NANAS DENGAN SENSOR WARNA BERBASIS ARDUINO

ABSTRACT Pineapple fruit is a kind of tropical plants originating from Brazil, Bolivia, and Paraguay This plant belongs to the family of pineapple-nanasan (Family Bromeliaceae). Low plant stature, herbs with 30 or more long, sharp-pointed leaves, arranged in a rosette form around a thick trunk. The cultivated pineapple has lost the ability to multiply sexually, but it develops young plants (the 'crown' part of the fruit) which is a means of vegetative propagation. Pineapple improves digestion and reduces acne. The maturity of the pineapple ranges from age 1-2 years depending on the variety of pineapple seeds used. The maturity of pineapple fruit can be seen through the basic colors, aromas, fruit eyes, crowns and flower stalks. For that researchers propose a system by utilizing the color sensor to detect the maturity of pineapple fruit with fruit color indication. The proposed system uses arduino microcontrollers, LCDs and buzzers to make it easier for users when the tool successfully detects that the pineapple has matured. The results of the analysis of the ability of color sensors to the color of pineapple fruit that is detected quite accurately, it is shown in the experimental results showed that when the color sensor detects the maturity of the pineapple fruit viewed from the color of the fruit then the system proposed by the authors immediately respond by issuing beeps and writing Ripe fruit in less than 5 seconds. This is very helpful device users in anticipating the risk of large losses due to rotting fruit pineapple or early harvest. From the test with a distance of 1-3 cm can be concluded that the color sensor is functioning perfectly, then the LCD responds quickly for less than 5 seconds in displaying mature writing, and buzzer beeps in accordance with its function.
