ANALISIS ASOSIASI DAUN SANG (JOHANNESTEIJSMANNIA ALTIFRONS) DENGAN JENIS-JENIS PALEM DI RESORT SEI BETUNG, TAMAN NASIONAL GUNUNG LEUSER, KABUPATEN LANGKAT, SUMATERA UTARA
ABSTRACT: Daun Sang is an
endemic species that can be found in Gunung Leuser National Park and Bukit Tiga
Puluh National Park. This palm is thought to have associations with other palm.
Where around Daun Sang grow there are palm types Lipai (Licuala spinosa), but
not always around Lipai grow Daun Sang are. Daun Sang need shade to grow
because these palm is sensitive to the sunlight. This study aimed to analyze the association of daun sang by some kind of palm that grows
around in order to conservation and optimize the cultivation of the daun sang.
The method used is a descriptive method with observation of the Daun Sang
number and some kind of of palms around it done intentionally (purposive
sampling). The method is performed by making 2 plot observations, each size is
100m × 100m, then divided by making the
sample plots of 20m × 20m. Observed data were processed using 2 x 2 contingency
table, and then calculated by the chi-square test formulations and Jaccard
index to calculate the extent of the association. three species of palm found
in the study site there are pinanga speciosa, tetradactylus and Plectomiopsis
Calamus sp. The results showed that daun sang are not associated with Pinanga
speciosa. Association occurs between daun sang with the Calamus tetradactylus
and daun sang with Plectomiopsis sp. The highest level of association occurs in
Daun Sang and Calamus tetradactylus with maximum association index value of 1.
The level of association between Daun Sang with Plectomiopsis sp. approaching
the maximum value of the association index in 0.84.
