| dc.description.abstract | Small industrial activity or informal business at this time varies in many types and variety,
one of which is laundry service. Laundry business today is quite widespread in Daerah
Istimewa Yogyakarta. Laundry business operationally uses detergent as cleaning agent besides
water. Material which is contained in fabric softener and detergent is ammonium chloride,
Linear Alkyl Sulfonate (LAS), sodium dodecyl benzene sulfonate, sodium carbonate, sodium
sulfonate, Alkyl benzene sulfonate (ABS). These materials are materials that are not
environmentally friendly (non-biodegradable). Until now laundry, entrepreneurs throw away
the liquid waste into water bodies, without being processed first. The purpose of this research
is to identify the effect of process of biofilter and carbon active coagulation toward laundry
effluent quality improvement. The research was a quasi-experimental (Quasi Experiment),
using the draft "Pre-Post Test Test With Control Group Design". The objective of the research
was the effluent wastes of laundry "X". The tested variable: the process of of biofilter and
carbon active coagulation. The affected variables were Biochemical Oxygen Demand (BOD),
Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS). The controlled variables
were Characteristics and effluent sampling time of the laundry. The location of the laundry "X"
was in Kajor, Banyuraden, Gamping, Sleman, Yogyakarta. The data were analyzed
descriptively and inferentially. Data normality used the Kolmogorov-Smirnov followed by
Multivariate Analysis of Variance (ANOVA), the significance level of p <0.05. Results of
multivariate analysis showed that Anova p = 0.000 (p <0.05), so that there was a significant
difference levels of BOD, COD and TSS between the treatment group and control group. After
doing the process biofilter and active carbon coagulation, there was laundry effluent quality
improvement for the average BOD levels was 145 mg / L to 28.27 mg / L (the quality standard
was 50 mg / L); the average of COD levels was 328.29 mg / L to 70.25 mg / L (the quality
standard was 125 mg / L); the average of TSS levels was 39.93 mg / L to 6.07 mg / L (the
quality standard was 200 mg / L). The effectivity of biofilter and active carbon coagulation
process toward the laundry effluent quality improvement for BOD was 79.01%; COD was
77.93%; and TSS was 84,19%. There were significant differences of the levels of BOD, COD
and TSS between treatment groups of biofilter and active carbon coagulation with the control
group toward the laundry effluent quality improvement. | in_ID |
