Abstract

TSM (Total Suspended Matter) adalah material tersuspensi berupa zat organik maupun anorganik yang memiliki diameter >1mm yang  berada di permukaan air, sedangkan Klorofil-A adalah kelompok pigmen fotosintesis yang menyerap cahaya biru, dan merah, serta merefleksikan cahaya hijau. Keduanya dengan jumlah yang besar dapat menutupi permukaan air dan membuat air menjadi hangat dan mengurangi kemampuan air untuk memenuhi kebutuhan oksigen untuk kehidupan biota laut dengan kata lain dapat menganggu ekosistem perairan. Dalam pengamatan kualitas air, perlu adanya pengamatan tentang TSM dan Klorofil-A untuk waktu dan tempat yang spesifik, serta berkelanjutan. Data pengideraan jauh dapat menganalisa beberapa parameter dalam cara spasial dan temporal. Akan tetapi masalahnya adalah sulit untuk menemukan algoritma yang sesuai untuk setiap daerah. Dikarenakan setiap daerah memiliki karakteristik yang belum tentu sama. Dengan menggunakan data time series akan lebih baik dalam memonitoring kondisi kualitas air. MODIS adalah  satelit yang memiliki time series harian, jadi sangat bagus untuk pengamatan daerah perairan. Data yang digunakan dalam pengamatan ini adalah Terra-MODIS level 1B resolusi 250 meter dan 500 meter bulan januari sampai september dan di validasi dengan data in situ bulan Agustus 2012. Beberapa model persamaan digunakan dalam penelitian ini untuk menganalisis sebaran konsentrasi TSM dan Klorofil-A. Hasil pengolahan data didapatkan transformasi kromatisiti kanal merah pada MODIS dapat digunakan untuk analisa sebaran koefisien TSM dengan nilai koefisien korelasi (R2) sebesar 0,484 sedangkan rasio antara kanal NIR dengan Kanal biru dapat digunakan untuk analisa sebaran konsentrasi Klorofil-A dengan koefisien korelasi sebesar (R2) 0,924.

Abstract

Shoreline is an imaginary line separating land and seawater. The intensification of land used/land cover at Lampung bay causes shoreline change either abrasions or accretions. The objectives of this study were to compare the shoreline extraction based on the digital image processing of SPOT-4 using ratio band of infrared and green band, Normalized Difference Vegetation Index (NDVI), and (band infrared) methods and to analyze shoreline change at Lampung Bay. Those methods applied on both cloudy free and cloudy SPOT-4 images and the result compared with RBI map as reference. The result showed that the best metod for shoreline axtraction was ratio band due to accuracy high and stable eventhough it applied on cloudy image. The shoreline changes at Lampung Bay along 2008 to 2012 caused by accretions. The total area of accretion at Lampung Bay for fours years were 662 Ha with the rates 165 Ha/year. The high of accretion rate caused by reclamation for urban built up, fishponds and mangrove.

Abstract

Remote sensing technology can be used to obtain information bathymetry. Bathymetric information plays an important role for fisheries, hydrographic and navigation safety. Bathymetric information derived from remote sensing data is highly dependent on the quality of satellite data use and processing. One of the processing to be done is the atmospheric correction process. The data used in this study is Landsat 8 image obtained on June 19, 2013. The purpose of this study was to determine the effect of different atmospheric correction on bathymetric information extraction from Landsat satellite image data 8. The atmospheric correction methods applied were the minimum radiant, Dark Pixels and ATCOR. Bathymetry extraction result of Landsat 8 uses a third method of atmospheric correction is difficult to distinguish which one is best. The calculation of the difference extraction results was determined from regression models and correlation coefficient value calculation error is generated.

Abstract

The  paper  describes inherent optical properties  (IOP)  of  the  Berau  coastal  waters  derived from in  situ measurements  and Medium  Resolution  Imaging  Spectrometer  (MERIS) satellite  data. Field  measurements  of optical  water,  total  suspended  matter  (TSM), and  chlorophyll-a  (Chl-a) concentrations were carried out during the dry season of 2007. During this periode, only four MERISdata were  coincided with in  situ measurements on 31 August  2007. The MERIS  top-of-atmosphere radiances were atmospherically corrected using the MODTRAN radiative transfer model. The in situ optical  measurement  have  been  processed  into apparent optical properties  (AOP) and sub  surface irradiance. The remote sensing reflectance of in situ measurement as well as MERIS data were inverted into  the  IOP  using quasi-analytical algorithm  (QAA).  The  result  indicated  that coefficient  of determination (R 2) of backscattering coefficients of suspended particles (bbp) increased with increasing wavelength,  however  the  R2 of  absorption  spectra  of  phytoplankton  (aph)  decreased  with  increasing wavelength.
