Abstract

The diversity of wild Begonia in West Sumatra is not well understood, while the habitat of Begonia has continuedly decreased by human activity or natural disaster. Therefore, some species are seriously undert hreat. Examinations of Begonia spp. were carried out using herbarium specimens from Andalas University Herbarium (ANDA), Herbarium Bogoriense (BO) and some field works in West Sumatra were conducted. A total of 33 species of Begonia were collected and identified as species level and could be used for identied Begonia species from West Sumatra.

Abstract

Secara historis, tanaman obat telah digunakan sejak zaman kuno. Tanaman obat mudah ditemukan di lingkungan masyarakat, masyarakat menggunakan tanaman obat sebagai pengobatan alternatif jika sakit. Berbagai jenis tanaman obat menjadi kesulitan bagi masyarakat dalam memilih tanaman obat yang dibutuhkan, karena ada yang bentuk sama tapi beracun sehingga akan berakibat fatal bagi pengguna. Karakteristik bentuk tanaman obat dapat digunakan untuk dibuatkan suatu sistem yang mempermudah masyarakat dalam mengenali tanaman obat. Metode yang digunakan dalam penelitian ini adalah PPDIOO (Prepare, Plan, Design, Operate, Optimize), agar sistem ini dapat dijangkau luas di masyarakat, maka konsep Internet Of Things (IoT) merupakan pilihan yang tepat, penggunaan algoritma Convolution Neural Network (CNN) untuk akurasi gambar dalam pengindraan.
