Abstract
The purpose of this research is to see the object changes in underwater that occurred from 2008 to 2019 and
also compare both the accuracy of image interpretation method for seagrass ecosystem object. The method is
used to detect a seagrass ecosystem is the supervised classification and the Lyzenga. The supervised
classification method uses the spectral sensitivity of each pixel value of seagrass ecosystem objects and the
Lyzenga method using attenuation coefficients based on sharpening the spectral values of pixels to a certain
depth to increase of the reflected values of seagrass ecosystem objects. The results of the interpretation
showed there were significant changes in the object of the seagrass ecosystem from 2008 to 2019. Supervised
classification method detected a widespread decline from 2013 to 2019 as much 19.16 ha. Lyzenga method
detects the same changes but with different techniques until it is identified a decrease in seagrass ecosystem
area from 2013 to 2019 covering an area of 9.31 ha. Both of method are used have different levels of
accuracy, the supervised classification method has an accuracy of 78.43% while Lyzenga method shows an
accuracy of 88.23%, the Lyzenga method is the suitable method for detecting the underwater object changes
for seagrass ecosystem environment in Nirwana beach waters, Padang - Indonesia.

Key words: environmental, seagrass, supervised, lyzenga, padang
