Judul: Membangun Kunci Identifikasi Asterinaceae Berhifopodia Menggunakan k-Nearest Neighbour KarakterMorfologi
Abstrak: Each species of fungi is distinguished by a set of characters that are unique to that species. One of those are morphological characters. This study is aiming at setting up the interactive identification key of the Hyphopodiate Asterinaceae that consist of 37 species of Asterina, 1 species of Asterolibertia, and 4 species of Lembosia, using K-nearest neighbour method (KNN). KNN is one of classification methods that calculate similarity based on the distance between data training and data testing. A set of 116 morphological characters with two data types i.e 104 nominal data and 12 numeric data of 93 specimens were used to set up the models of the identification key. Euclidean distance was used for the numeric data type where as the Hamming distance was used for the nominal data type. The Euclidean distance and the Hamming distance will be combined by the aggregation function. The smallest value of aggregation indicated the degree of similarity between groups and the identity. Web-based interactive identification key of Hyphopodiate Asterinaceae was used as a primary source of information of the diversity of Hyphopodiate Asterinaceae in the world for mycologists and other users. Data from 42 species each were used as data testing. It was found that the accuracy of normalized data was higher than the unnormalized data, with values of 100% and 78.38% respectively. Therefore, this web-based identification was developed by using the normalized numeric data.

Judul: Identifikasi shorea menggunakan k-nearest neighbour berdasarkan karakteristik morfologi daun
Abstrak: Dipterocarpaceae is a group of tropical plants that is used in a timber industry. One of Dipterocarpaceae clans is Shorea, that is the best timber-producing plant in the industrial world. Shorea is difficult to be identified because it has a lot of diversity. The inability to recognize Shorea in forest will enlarge the exploitation of Shorea that has a good timber quality, and silviculture work becomes less of the target because it is not known which Shorea species that will extinct. Shorea tree is usually identified by using the stems, leaves, fruits, and flowers. However, leave is used for the identification in this research because it tends to be available as a source of observation at anytime. The leaves in this reasearch are the collection from Bogor Botanical Gardens. Data are obtained by manual calculating to get the characteristics of the leaves. The obtained data will be processed using k-Nearest Neighbor to get the closeness of new data and training data. The leaves that are included in this research are Shorea multiflora, palembanica, balangeran, lepida and assamica, each one has 10 data. Each set of data has 10 attributes that support the leaf characteristics. From the whole data, Shorea are divided into five subsets including data training and data testing for each subset. This research has two experiments the first experiment without normalization produces 84% accuracy and the second experiment with a normalization produces 100% accuracy.
