ABSTRACT

Blackwater domestic waste is a type of wastewater that comes from human waste, so it needs proper treatment before being discharged into the river. So far, blackwater waste processing is carried out by storing it in a septic tank or directly channeling it to a sewage system to be processed in a domestic Wastewater Treatment Plant (IPAL). This study aims to increase the effectiveness of domestic wastewater treatment from communal IPAL using a physical model consisting of 2 processing processes, namely a stratified filter and a wetland. This study applied a stratified filter method consisting of gravel, activated charcoal and cast sand, then continued with a wetland system consisting of Vetiveria zizanioides (Vetiveria zizanioides) plants. The research variables observed were variations of wastewater discharge (X1), variations in thickness of sand (X2), wetland residence time (X3) at intervals of 2 days, 4 days and 6 days, and water quality parameters (Y) consisting of Fe. The data analysis method used is Linear Regression with the help of the SPSS program. The results showed that the use of a physical model consisting of multilevel filters and wetland was able to improve the quality of wastewater, where the output produced had met the quality standards of class IV agricultural water. The blackwater model for stratified filters and for Fe Akar wangi, obtained an equation of Wangi Root Fe = 374,489 - 1,787 X1 * - 9,127 X2 * - 13,383 X3 * + e1 with R Square 97.4% (X1, minute; X2, thickness of sand: X3 , day; * significant).
