Medicinal plants are plants that have benefit in order to supply the needs of familiestraditionally medicine. Medicinal plants have diverse types that causing modern society have difficulty inrecognizing these crops. Medicinal plants generally can be identified by the leaves, stems and fruit. One ofthe leaves characteristics can be distinguished based on vein structure and shape of its. Based on theseproblem, plant recognition based on vein and shape are made by using Localized Arc Pattern Method.There are two important processes in Plant Recognition Applications. First process is Enrollment andthe second is Recognition process. In the Enrolment process, the leaves image filed as many as 6 imagesfor each leaves type. This image then calculated based on the 42 special model pattern obtained and thefeature is stored as a reference image. Leaves images that used as test image are 200 images. On theRecognition process, the test image will be process which as same as at Enrollment process, howeverfeature from the test image will be comparing with reference image in database, then it calculate thedifference value. This process uses a threshold value to determine whether the test images leaves arerecognized or not. When dissimilarity value is smaller than the threshold is known as the same leaves,when instead then it known as a different leaves or not known at all. Experiment result shows in thisapplication can recognize 77% of total leaves and False Accepted Ratio (FAR) equal to 4.5% and FalseRejection Ratio (FRR) equal to 18.5%. This result was influenced by the shiny surface of leaf and shapeof the leaves are small.
