Pak Choy Leaf Width Detection using Image Processing with Canny Edge Detection Extraction Method

Pak Choy plant is a vegetable plant that can grow with soil and hydroponic media. Plant growth can be monitored by knowing the width of the plant's leaves. This research creates a tool to accurately detect plant leaf width through plant growth monitored by the people-research implementation in the form of a mobile application that can detect the width of plant leaves. Using the canny edge detection method, the results obtained system accuracy of 95.06%, the light intensity of 18.75 lux, angle of 90°, and distance of 30 cm. Pak Choy plant growth was seen for 4 weeks, the best accuracy was obtained at 2
^nd
week with an average accuracy of 99% and an average light intensity value of 22 lux.
