EFEKTIFITAS SEDIMEN TRAP PADA LAHAN SENTRA SALAK PADANG SIDIMPUAN DI TAPANULI SELATAN
Abstract: West Angkola
sub-districts and South Angkola is salak areas center of South Tapanuli that
partly has undulating to hilly topographic with steep slopes which is
potentially eroded. This study aims to determine the sediment trap and river on
the land in the district Angkola West and East as well as the correlation
between sediment discharge to the river flow and rainfall . The method used was
survey methods and data analysis to quantify the Water Catchment Area for each
Watershed by using software tools Arc Geographic Information System ( GIS )
10.1 . Sediment discharge calculated using the evaporation method . Regression
data analysis using the software SPSS 19. Results showed the highest sediment
discharge analysis on analysis in March in the District of East Angkola is 5.56
tons / day , while in April amounted to 9.2 tons / ha . Results of the analysis
of sediment discharge peak in March in the District of West Angkola amounted to
