Identifikasi Jenis Shorea (Meranti) Menggunakan Algoritme Voting Feature Intervals 5 Berdasarkan Karakteristik Morfologi Daun

Abstract

Shorea (Meranti) is the major timber-producing genera of the family Dipterocarpaceae. Dipterocarpaceae produce very high quality timber in the tropical rain forest region of Asia and has very high commercial value in the world industry. However, certain species of shorea are known to have low quality wood. Hence, the selection process of shorea species is essential in producing high quality shorea timber. There are 194 types of shorea species, which makes it difficult and impractical to identify each species manually. Only people with significant amount of experience can effectively identify different shorea species. This research aims to automatically identify shorea species based on the morphological characteristic of their leaves using Voting Feature Intervals 5 (VFI5). The data used in this research is obtained using manual measurement from shorea plants in Bogor Botanical Gardens. We use 5 species of shorea each having 10 instances for a total of 50 instances. Each instance is characterized by using the following morphological characteristics: length of the leaf, width of the leaf, venation of the leaf, surface of the leaf, tip of the leaf, base of the leaf, circumference, wide, angle, and amount of veins. Each characteristic is used as a feature for processing using VFI 5 algorithm. The best accuracy obtained in this research is 88%.
