Pola spasial dan temporal total suspended solid (TSS) dengan citra spot di estuari Ci Mandiri, Jawa Barat = Spatial and temporal patterns of total suspended solid (TSS) using spot imagery in estuaries Ci Mandiri, West Java
" ABSTRAK
TSS Total Suspended Solid merupakan material padatan dalam perairan yang tersuspensi berupa zat organik maupun anorganik yang jika keberadaannya banyak di perairan terutama di estuari dapat mengganggu ekosistem perairan di dalamnya. Penelitian ini menggunakan citra SPOT-4 tahun 2007 dan 2011, serta SPOT-6 tahun 2016 untuk mengidentifikasi konsentrasi TSS dengan menerapkan formula algoritma TSS. Hasil penelitian menunjukkan bahwa terdapat perbedaan pola spasial nilai konsentrasi TSS di Estuari Ci Mandiri pada tahun 2007, 2011 dan 2016. Faktor ... "

Modelling distributed hydrological and sediment processes to assess land use effects in Chao Phraya River Basin
" Soil loss and its transport processes were coupled with an existing distributed hydrological model to assess the effects of land use change on stream flow and suspended sediment load in the Chao Phraya River basin, Thailand. The simulation period spanned from 2001 to 2010. The results indicate that the Nash-Sutcliffe efficiency of upper sub-basins fluctuated in the range 0.51- 0.72, indicating the applicability of the model for longterm simulation at the monthly scale. Land use change during 200l-2010 caused a ... "

Heavy metals suspended sediments in river flowing through megacities in Southeast Asia
" Heavy metals in suspended sediments (SS) were investigated in the lower Chao Phraya River, Thailand, and Main particulate metals. The particulate fractions accounted mostly for 60-100% of total concentrations of Cr, Mn, Ni, Cu, Zn, and Pb in both dry and rainy seasons. The comparison of metal contents of the sampled SS and upper continental crust (UCC) implied some anthropogenic inputs of Cr, Ni,Cu, and Zn as well as the dilution process for those metals in ... "

Sebaran Logam Berat pada Sedimen Tersuspensi di Perairan Teluk Lasolo, Kecamatan Molawe, Kabupaten Konawe Utara = Heavy Metals Distribution in Suspended Sediments at Lasolo Bay, Molawe Subdistrict, North Konawe District
" Logam Berat merupakan jenis pencemar di perairan yang berkaitan erat dengan Total Padatan Tersuspensi (TSS). Eratnya hubungan dari kedua parameter tersebut dapat menjadi potensi dalam menilai secara tidak langsung logam berat di perairan. Penelitian ini bertujuan untuk mengetahui hubungan antara TSS dan berat Nikel (Ni) dan Tembaga (Cu) yang terikat didalamnya, kemudian distribusi TSS di perairan diestimasi menggunakan teknik penginderaan jauh untuk menggambarkan secara tidak langsung distribusi kedua logam berat tersebut, dan mengetahui pengaruh dari ...

Distribution and ecological risk assessment of plasticizers in the Chao Phraya Delta, Gulf of Thailand
" Preceding monitoring reports indicated that di (2-ethylhexyl) phthalate (DEHP), a common plasticizer, was found in the samples of suspended sediment and water collected from the lower part of Chao Phraya River. In this continuing study, the suspended sediment and water samples from the Chao Phraya Delta were collected twice a year in January and July during January 201 1 - July 2013. The analyses were performed for both DEHP and Diethyl Phthalate (DEP). Overall results showed that concentrations of both ... "
