ANALISIS DINAMIKA SEBARAN SPASIAL SEDIMENTASI MUARA SUNGAI CANTUNG MENGGUNAKAN CITRA LANDSAT MULTITEMPORAL
ABSTRACT: Given the pivotal
role played by the Cantung River for the supervision and management of the
public good becomes important. Incoming sediment load can damage the
uncontrolled flow conditions of the Cantung river and estuary. Observations of
suspended sediment can take advantage of multitemporal Landsat imagery. This
study uses Landsat satellite image data corrected 5TM March 5, 1992 data
acquisition path/row 117/62, Landsat data acquisition 5TM 22 May 1997 path/row
117/62, Landsat data acquisition 5TM March 27, 2000 the path/row 117/62.
Several stages in processing the image, that is the conversion of DN to
reflectance values, cropping, water-not water secession, and the class divide
sediment concentration by density slicing technique. Spatial distribution of
suspended sediment in the estuary of the Cantung River Landsat image processing
results 5TM March 5, 1992, Landsat 5TM May 22, 1997, and March 27, 2000 Landsat
5TM show distribution patterns of suspended sediment from the River Cantung the
same direction, that is northeast. Sediment concentrations were detected in the
Landsat image processing 5TM March 5, 1992 the largest-value 27,564096 mg/l and
the smallest 14,886048 mg/l. Sediment concentrations were detected in the
Landsat image processing 5TM May 22, 1997 the largest-value 121,476776 mg/l and
the smallest 12,647415 mg/l. Sediment concentrations were detected in the
Landsat image processing 5TM March 27, 2000 most valuable 159,256704 mg/l and
the smallest 10,584161 mg/l. Getting away from the effect Cantung River estuary
sediment concentration of river flow Cantung tends to get smaller. Changes in
the distribution area of the sediments of March 5, 1992 until March 27, 2000
amounted to 450 m2/year.
