KARAKTERISTIK MORFOLOGI KEPEL (Stelechocarpus burahol [Bl.] Hook. F. & Thomson) DI KABUPATEN BANTUL
Abstract
This study aims to determine the morphological characteristics of kepel that
grow in Bantul district and determine the level of diversity and kinship of kepel
plants in order to obtain grouping characteristics. This research was conducted in
Bantul district in October 2018 to January 2019, measurement of leaf samples was
carried out in an in vitro culture laboratory, while soil analysis was carried out at
the Soil Science Laboratory, Faculty of Agriculture, Muhammadiyah University,
Yogyakarta.
The study was conducted using a survey method. The method of taking plant
samples using purposive sampling technique, which is sampling by specifying
specific characteristics of the sample plants, namely plants that have never been
fruitful and are in Bantul district. The observation data was changed to a scoring
form and then analyzed to assess the similarity matrix using the SIMQUAL
(Similarity for Qualitative Data) procedure. Furthermore, the matrix data grouping
and the making of dendograms are performed using the Unweigthed Pair-Group
Method Arithmetic Average (UPGMA) method using numerical Taxonomic and
Multivariate System (NTSYS) version 2.02i.
The results showed that uniformity in canopy shape and leaf edge shape, but
had diversity in leaf blade shape, leaf base, leaf tip shape, leaf color, leaf length,
leaf width, leaf stem length, stem color and number of branches. Based on the
similarity of morphological characteristics at the level of coefficient similarity of
0.602 kepel in Bantul district can be grouped into four groups, cluster 1 (27 plants),
cluster 2 (8 plants), cluster 3 (8 plants), and cluster 4 (1 plant). The closest kinship
relationship on 1.00 coefficient similarity index is Piyungan 2 with Banguntapan 3,
Pajangan 1 with Banguntapan 4, Jetis 3 with Banguntapan 2, dan Pajangan 2 with
Imogiri 2.
