摘要:Mangrove forest condition in Muaragembong area is continuously decreased.It triggered erosion escalation in land area that brings sedimentary material to silt the coastal area up and harm the mangrove ecosystem.This study is purported to analyze the relationship between water's TDS concentration and TOA,formulate TDS estimation model,and determine the best type of spectral Landsat image.This study used samples to test the sediment content,develop TDS estimation model on acquisition imagery reflectance,and data analysis on Landsat-8 OLI satellite images.The study finds a strong relationship between TDS concentration in the water area and TOA,which reflected on the amount correlation score -0,782.The study also concludes that exponential is the best TDS estimation model and the best spectral Landsat image is band-6.The research policy recommendations are to carry out mangrove rehabilitation and the construction of a breakwater around the Muaragembong mangrove zone.
其他摘要:Kondisi hutan mangrove di kawasan Muaragembong terus mengalami kerusakan dan telah memicu peningkatan erosi di daratan yang menyebabkan sedimentasi,seperti pendangkalan perairan pesisir dan kerusakan pada ekosistem mangrove.Tujuan penelitian yaitu menganalisis hubungan antara konsentrasi total dissolved solids (TDS) perairan dengan top of atmosfer (TOA),menyusun model persamaan pendugaan TDS,dan menentukan jenis spektral citra landsat yang terbaik.Metode penelitian ini berupa pengambilan data dan uji sampel kandungan sedimen,mengembangkan model pendugaan TDS pada acquisition imagery reflectance,dan terakhir,pengolahan data citra satelit Landsat-8 OLI.Hasil penelitian menunjukkan korelasi antara konsentrasi TDS di perairan dan TOA sebesar -0,782.Kesimpulan penelitian menunjukkan terdapat hubungan kuat antara konsentrasi TDS perairan dengan TOA,model persamaan pendugaan TDS terbaik yaitu model eksponensial serta jenis spektral citra landsat yang terbaik adalah band-6.Rekomendasi kebijakan penelitian adalah melakukan rehabilitasi mangrove dan pembangunan breakwater di sekitar zona mangrove Muaragembong.
