Struktur Populasi Bekantan (Nasalis larvatus) di area Gunung Batu Sawar Kecamatan Hulu Sungai Tengah
Abstract: Proboscis
monkey (Nasalislarvatus) is a species
of primates endemic
in Borneo. According
to South Borneo Governor's Decree No. 29 Year 1990
dated January 16 at1990, proboscis monkey is set to be a mascot fauna of South
Borneo Province. The habitat of proboscis monkeys are usually found along the
rivers and swamp areas in Borneo. Research of proboscis monkeys who live in
mountainous areas are still very rarely done so little known by the public.
Therefore , to determine the condition of proboscis monkeys in a habitat of
them to do research on the structure of the population. The purpose of this
study was to calculate the number , density and age structure of the population
pyramid illustrates the proboscis monkey (Nasalislarvatus). The method used is
descriptive method by calculating the concentration technique (concentration
count). The study was conducted on a population proboscis monkey (Nasalislarvatus) in
the area of
BatuSawar Mount in
Hulu Sungai Tengah
District. Data analysis
was performed by direct calculation during primate visible. The largest
number of individuals encountered on a whole series of observations is assumed
as the number of individuals that represent a group, whereas the smallest
number of individuals encountered
is assumed that
the other individual
is not visible
at the time
of observation.The observation of
the proboscis monkeys (Nasalislarvatus) found in the area of research were
adult proboscis monkey amounted to 17 with a density of 0,028 ind / ha,
totaling 23 juveniles proboscis monkey with a density of 0.038 ind / ha,
and child proboscis
monkey amounted to
13 with a
density of 0,022
ind / ha. The
population structure of proboscis
monkey (Nasalislarvatus) in the area of BatuSawarmountain in Hulu Sungai Tengah
district if depicted using the age pyramid, the pyramid form a jug or bowl.
