Abstract:
Bakut Island is one of the conservation forest areas in South Kalimantan.
This island is the habitat of proboscis monkeys, and the proboscis monkey
population is increasing from year to year. Therefore, it is estimated that one day the
proboscis monkey habitat on Bakut Island will be over capacity. This study aims to
estimate how long the population of proboscis monkeys on Bakut Island Nature
Tourism Park can survive there by examining the amount of food the island's
vegetation can produce. Proboscis monkey feed itself is estimated using the Leaf
Area Index (LAI). LAI was extracted using UAV imaging and NICFI multitemporal
imagery. Meanwhile, the carrying capacity of the proboscis monkey habitat is
assessed using the quantity of consumption of the proboscis monkey population
relative to food availability. Simulations of the carrying capacity of proboscis monkey
habitat into the future were carried out using projections of the future proboscis
monkey population and LAI growth. The entire computational process of simulating
habitat carrying capacity is carried out using the Python language. The results of the
analysis show that Bakut Island is only able to support proboscis monkey habitat
until 2038. In that year, the proboscis monkey population on Bakut Island is
projected to number 1,290 individuals. After 2038, the predicted amount of feed
needed by the proboscis monkey population will exceed the feed available on Bakut
Island. The limitation of this research is that it only uses one parameter to assess the
carrying capacity of proboscis monkey habitat, namely food availability. There are
still other parameters that have not been accommodated, including the home range
and trees for nests.
