Abstract

This research aims to find out the decrease effectivity of dodecil benzene suphonate (DBS) concentration
from detergent waste treated using activated sludge. This research was carried out in two steps : the first step was
seeding process or preparation of the activated sludge. This was carried out on plastic container of 2 L. About 3 g
sediment taken from Tukad Mati, 1 g NPK were mixed in a plastic container. The volume was made 1 L by adding
aquadest, the mixture was aerated for 1 week. The second step was treatment of detergent waste which was carried
out using 2 plastic container of 5 L each. About 2 L detergent waste and 1 L activated sludge solution were mixed in
the plastic container. Mean while, 3 L detergent waste as a control were palced in the other plastic container. Both
container were aerated for observation for decrease DBS concentration was carried out during 0, 3, 5, 7, 10 and 15
days. DBS concentration was analyzed using Methylen blue method.
The research result indicated that generally, there were decrease of BDS concentration both in control and
treated samples. The lowest DBS concentration was observed on day 15 both on control and treated samples with
value, of 46.726 and 0.381 mg/L respectively. The decrease effectivity were 8.18% for control and 99,25% for
treated samples. From this research, it can be seen that treatment of waste using activated sludge was effective to
decrease DBS concentration in detergent containing waste.
