| dc.description.abstract | Jember University campus with an area of 65.7 ha covered by many different
types of plants that can form the flora. This study aims to determine the diversity
of tree species in Jember University Campus. The study was conducted in May
upto October 2011. Measurement of Jember University campus area and the
extent of each Faculty and Program Studies were conducted using the Global
Positioning System (GPS). Census method was used to identify and count the
number of trees at the study site. Environmental parameters were measured at
each study site, include: the degree of acidity (pH) of soil, soil texture, air
temperature, and humidity. Species diversity index is determined using the
Shannon-Weiner formula. Abundance type is determined by the criteria used in
the abundance of individual species of trees. Importance value index of type is
used to observe the dominance of plant species at each location. The results
showed that in Jember University Campus, there were forty-three species of trees
with a total of as many as 789 tree species and the species density was achieved
by Swietenia macrophylla King. Jacq. (6.41), followed by Samanea saman Jacq.
Merr. (3.28) and Spathodea campanulata Beauv. (2.41), respectively. Of all types
of existing trees, three species dominates, namely Swietenia macrophylla King.
Jacq., Samanea saman Jacq. Merr., And Spathodea campanulata Beauv .. The
index value the importance of trees in the University of Jember ranged from 0.85
at the tree Tectona grandis L. f. and Bombax ceiba L. until 46.39 on the tree
Swietenia macrophylla King. Jacq .. The most dominant tree species on the
University Campus Jember is Swietenia macrophylla King. Jacq. followed by
Samanea saman Jacq. Merr. and Spathodea campanulata Beauv., respectively.
Tree species diversity index values in the range of 0.20 at the Nursing Science
Program (PSIK) up to 2.66 at the Faculty of Agriculture, which means it has
relatively low species diversity through the medium. The total area of study site is
27.75 ha with a mean value of 1.98 ha each faculty. | en_US |
