Abstract

Background. Septic tanks that are commonly used in the community are conventional septic tanks. The use of this septic tank is still not optimal because the processing efficiency has only reached 65%, causing only 22.5% of the total organic pollutants that can be processed (Said, 2005). In addition, low efficiency causes rapid accumulation of sludge which reduces the service life of the septic tank. Aim. This study aims to determine the differences in the efficiency of conventional septic tanks and modified septic tanks in reducing levels of BOD, TSS, and Coliform in household wastewater. Method. This research is an experimental study using a one group pretest-posttest research design. Results. The results showed that conventional septic tanks were not efficient in reducing BOD (-38.21%) and Coliform (0%), as well as very small efficiency in reducing TSS content (5.09%) in wastewater, modified septic tanks had little efficiency for reducing BOD content (2.4%), but it is very efficient for reducing TSS content (89.44%) and inefficiency to reduce coliform content (0%) in wastewater. Conclusion. There was no significant efficiency difference between conventional septic tanks and modified septic tanks in reducing BOD and Coliform content, but there were significant efficiency differences between conventional septic tanks and modified septic tanks in reducing TSS content in the wastewater.
