Paper Abstract

The Lancang Island waters have the potential of marine biological resources such as the crab (Portunus pelagicus). The crab is a species that eats suspended material. Remote sensing can estimate the parameters of Total Suspended Solid (TSS). The purpose of this study was to estimate the distribution and test the accuracy of TSS concentrations in Lancang Island waters extracted from Landsat 8 OLI images by field observations. Statistical test indicators that can be used for accuracy tests include; root mean square error (RMSE), mean absolute error (MAE) and normalized mean absolute error (NMAE). The results of the RMSE value was 11.5 showed that the size of the error based on the difference between the value of the image and field data. The smaller the RMSE value, means the results of the model estimation produced was more precise with those observations. The MAE value of 1.774 showed the simplest form of error size. The MAE results indicated that it could be seen that the prediction error of the distribution of TSS was too small. It means the prediction of the distribution of TSS in this study had high accuracy. The NMAE of 31.9% shows the error rate that is normalized and expressed in percent (%). The NMAE value below 30% that could be used as proof of the validity of image data. The high error value was caused by differences in the time taken by field data with the recording time of satellite images and the effect of thin cloud cover.
