| dc.description.abstract | Research on Spatial Modeling Analysis of Habitat Suitability of Carrion Flower
(Amorphophallus variabilis Blume.) In North Sumatra Province, Indonesia Using the
Maximum Entrhopy method, carried out from October 2022 to January 2022. This
research was conducted by collecting data using the Maximum Entropy (MaxEnt)
method to determine habitat priority areas that can later be used as priority areas to
determine the distribution prediction model. Using primary data in the form of sample
coordinate points of findings and secondary data using maps of soil type, slope, area
height, topography, river distance, road distance, land cover and maps of 19 climate
variables. Each map will be equalized by projection and extand units with a sell size of
0.00833 and a distance resolution of 1 km2 with decimal degrees. The equalized map is
divided into two layers in the MaxEnt analysis, the coordinate layer uses sample
coordinate point data converted in the form of Comma Separate Value (CSV) and the
Environmental Layer includes all maps of environmental variables converted in the form
of Actionscript Communication (.asc) which will be analyzed to produce one map
modeling the suitability of A. variabilis habitat. The results of the map analysis for three
replicates obtained variables that are able to make an important contribution to the
modeling show that soil type, temperature, slope, altitude and rainfall are the biggest
influences on the modeling of A. variabilis habitat suitability. The most suitable area for
A. variabilis growth is in the Mandailing Natal region adjacent to the West Sumatra
Region. It is recommended to use variables and use more observation track points to
determine the distribution of this species and further research related to the benefits and
conservative treatment of A. variabilis in areas considered to be very important.
variabilis in areas that are considered very suitable and suitable. Socialization to
ordinary people about the benefits, processing and cultivation of A. variabilis needs to
be done to maintain the stability of the A. variabilis population and increase the income
of local communities. | en_US |
