Pembelajaran Klasifikasi Kladogram Dengan Metode Taksimetri Untuk Mempelajari Kekerabatan Tanaman Genus Tillandsia & Neoregelia

The environment of State Senior High School (SMAN) 3 Malang employed a concept of
vertical garden, making the environment suitable for outdoor learning and direct learning.
Observation results indicated the use of plants for learning media is not optimal due to the lack
of information on scientific names, descriptions, and relationships of plants. Based on the
observation, it was necessary to design a learning innovation. This research aimed to describe
the application of Cladogram classification learning with the Asymmetric method: 1) the
utilization of Tillandsia & Neoregelia plants for the source of plant classification & Cladogram
learning, 2) the number of Tillandsia & Neoregelia species, 3) the relationship between
Tillandsia & Neoregelia plants. This research employed a descriptive survey method through
learning classification & Cladograms with Asymmetry. The descriptive data analysis technique
defined the identification of plant types using pictures and key books of determination
(asymmetry). The results showed that through the learning of cladogram classification with the
asymmetry method, the following data were obtained: 1) the use of plants with morphological
characteristics and similarities and differences became the source of learning for plant
classification and making cladograms effectively indicated by students performance in doing the classification of plants in the school environment and making cladograms from
classification activities, 2) there were two species of tillandsia namely Tillandsia lonantha &
Tillandsia cyanea, and there was one neoregelia species namely Neoregelia spectabilis, 3)
familial relationship of the plant is one family namely Bromeliaceae.
