Aims: to know and determine plants diversity and similarity
in three communities of S. jamaicensis habitat.
Study Design: Explorative and descriptive.
Place and Duration of Study: Research in Gajahrejo Village,
Pasuruan, East Java Province was conducted in August 2012; in Kepala Jeri
Islands Batam, Riau Island Province in October 2014; and in Bissoloro Village,
South Sulawesi Province conducted in October 2016.
Methodology: The study used exploratory and descriptive
methods. Sample plots of 1m x 1m were determined and put around S. jamaicensis,
which was found along the edge of village roads during exploration (purposive
random sampling). Vegetation analysis was carried out to determine the
composition, dominance, diversity, evenness and similarity of the species in
each S. jamaicensis growing place by counting the Important Value Index,
Similarity Index, Shannon Diversity Index, Domination Index, and Evenness Index.
Results: Assosiant plant species found in the three sites
growing area of S. jamaicensis were 84 species, 74 genera and 28 families.
There were six plant species obtained in the three sites growing area of S.
jamaicensis, i.e., Ageratum conyzoides L., Axonopus compressus (Swartz) Beauv.,
Centrosema pubescens Bth., Chromolaena odorata (L.) R.M.King & H. Rob.,
Cynodon dactylon (L.) Pers and Mimosa pudica L. Axonoppus compressus was the
most dominance species in Kepala Jeri Island and Bissoloro Village, whereas
Panicum brevifolium L. was the most dominant species in Gajahrejo Village. The
difference in floristic composition between the sites may be caused by
environmental factors, human activity, land use systems and disturbance on
fields where S. jamaicensis obtained.
Conclusion: The plants' diversity and similarity in the
three sites growing area of S. jamaicensis habitat were different. There were
84 species, 74 genera and 28 Families found in three sites growing area of
S.jamaicensis. There were six plant species obtained in the three sites growing
area of S. jamaicensis, i.e., Ageratum conyzoides L., Axonopus compressus
(Swartz) Beauv., Centrosema pubescens Bth., Chromolaena odorata (L.) R.M.King
& H. Rob., Cynodon dactylon (L.) Pers and Mimosa pudica L. Axonoppus compressus
(Swartz.) Beauv. was the most dominant species in Kepala Jeri Island and
Bissoloro Village, whereas Panicum brevifolium L. was the most dominant species
in Gajahrejo Village.
