Abstract

Total Suspended Matter (TSM) dan klorofil-a merupakan parameter kualitas air yang dapat dipetakan dengan penginderaan jauh. Nilai TSM yang tinggi dapat mempengaruhi klorofil-a dalam fitoplankton untuk berfotosintesis. Penelitian ini bertujuan untuk menganalisis sebaran, akurasi, serta hubungan antara parameter TSM dan klorofil-a berdasarkan data in situ dan data citra di perairan Pesisir Prigi. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif. Data yang digunakan adalah citra Landsat 8 tanggal 20 Mei 2018 dan sampel in situ yang diambil dengan menggunakan teknik purposive sampling di 9 lokasi pada tanggal 19 Mei 2018. Dari penelitian ini didapatkan hasil nilai TSM in situ berkisar 41-64 ppm, nilai TSM citra berkisar 44–65 ppm, nilai klorofil-a in situ berkisar 1,15-2.68 mg/m3, dan nilai klorofil-a citra berkisar 1,24-2,41 mg/m3. Dari hasil data in situ dan citra didapatkan akurasi sebesar 74,37% untuk TSM dan 80,33% untuk klorofil-a. Nilai hubungan TSM dan klorofil-a adalah y= -0.045x + 3.9103 dengan nilai koefisien 85%, yang artinya variabel X yaitu TSM mempengaruhi variabel Y yaitu klorofil-a. Kesimpulan dalam penelitian ini adalah perairan Pesisir Prigi memiliki nilai yang berada pada ambang batas masing – masing parameter, sehingga perairan Pesisir Prigi tergolong baik. Akurasi yang tinggi antara data citra dan data in situ menunjukkan metode penginderaan jauh sesuai untuk digunakan di wilayah perairan Pesisir Prigi.

Abstract

Total Suspended Matter (TSM) and chlorophyll-a are water quality parameters which can be mapped using remote sensing. High TSM values could affect chlorophyll-a in phytoplankton for photosynthesis. The aims of this research were to analyze distribution, accuracy, and relationship between TSM and chlorophyll-a based on the imagery and in situ data in Prigi Coastal waters. The method that used in this research was descriptive. The data used was Landsat 8 imagery that captured on May, 20th 2018 and in situ samples taken using purposive sampling technique in 9 locations on May, 19th 2018. From the results of this research, TSM in situ value ranged from 41-64 ppm and imagery value ranged from 44-65 ppm, chlorophyll-a in situ value ranged from 1.15-2.68 mg/m3, and imagery value ranged from 1.24-2.41 mg/m3. From the results of in situ and imagery data obtained the accuracy value for TSM 74.37% and for chlorophyll-a 80.33%. The relationship between the TSM and chlorophyll-a value was y= -0.045x + 3.9103 with a coefficient value 85%, which means that the variable X (TSM) affects the variable Y (chlorophyll-a). The conclusion of this study was Prigi Coastal waters had a value at the threshold of each parameters. So, could be classified as good quality of waters. High accuracy between imagery and in situ data shows that remote sensing method was suitable for use in the Prigi coastal waters.
