J. of GEOMATE.This study was aimed to identify physicochemical and biological determinant parameters in assessing the ecological status of the upstream area of CitarumRiver during the dry and rainy season. This study consisted of two steps: 1) Principle Component Analysis to classify environmental parameters and select the determinant environmental parameters significantly affecting the status, and 2) matrix arrangements using the selected determinant parameters for ecological status assessment. The PCA results showed that during the dry season, genera macrozoobenthic and physicochemical parameters grouped the slightly-quite-moderately polluted status. In the rainy season, macrozoobenthic and physicochemical parameter grouped the quite-moderately polluted status. Based on the selected determinant parameters, it could be stated that 1) Leuctra sp., Perlesta sp, and total sediment nitrogen determine the slightly polluted status, 2) Baetis sp., Sulcospira sp., conductivity, and NO3-determine the quite polluted status, 3) Lumbriculus sp., Chironomus sp., NO2, silt, and BOD determine the moderately polluted status. While the determinants during the rainy season in quite and moderately polluted location were: 1) Hydropsyche sp., Rhyacophila sp. and gravel in the quite polluted status, 2) Placobdella sp., Tubifex sp., TSS and NH3 in the polluted status. The assessment matrix arranged using determinant parameters were able to determine the ecological status of the Citarum upstream in the rainy (quite-moderately polluted) and the dry season (slightly-quite-moderately polluted).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Determinant parameters,Ecological status,Polluted status[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The financial support received from P3MI Fund of Bandung Institute of Technology is gratefully acknowledged.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.21660/2018.50.13321[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
