Abstract

This  research  focus  to  examine  changing  mangrove  area  during  5  years  and  their  relationship  with  perception  of  Dusun  Pintau  people.  Raster  and  vector  data  were  used  in  this  research.  Raster  data  is  processed  by  georeferencing  and  geoprocessing.  Other  that,  purposive  sampling  was  used  to  determine  number  of  respondents.  From  vector  data  is  known  that  mangrove  area  constant  at  58.58  Ha  in  5  years,  this  mean,  it  area  didn"™t  change.  From  raster  data,  it  area  was  changed  which  are  16.3  Ha  in  2012,  18.52  Ha  in  2013,  18.89  Ha  in  2014,  and  18.9  Ha  in  2015.Base  on  terestris  data,  also  reveal  changed  18.8  Ha  in  5  years.  From  correspondency  activity  reveal  that  mangrove  area  is  12  Ha.  People"™s  perception  to  mangrove  area  change  is  different  depend  on  age,  education  background,  and  cosmopolitan  level.  66.7%  young  people  have  positive  perception,  adult  people  who  have  positive  perception  is  50%,  and  mature  people  generally  (60%)  have  positive  perception.  Base  on  education  background,  58%  of  elementary  school  alumna,  46%  junior  school  alumna,  and  81.18%  senior  school  alumna  have  positive  perception.  Base  on  this  study,  mangrove  forest  area  in  Dusun  Pintau  has  change.  It  area  was  decrease  0.58  Ha/year.  This  degradation  was  caused  by  fish  and  shrimp  farm  construction  during  five  year.
