Abstract:
This research was aimed to analyze the ability of perupuk (Phragmites karka Trin) in
reducing the element of rubber industrial liquid waste polluters on the scale of the
laboratory. The method used was the method of survey. The data from laboratory test
were tabulated and analyzed descriptively and the level of efficiency was calculated.
Referring to South Kalimantan Governor Regulation Number 36 in 2008, the results
showed that, TSS parameters started to be effectively reduced on day 10 (T 1) with
close to 84,33 mg/l (32.53%), BOD5 started to be effectively reduced on day 20 (T 2)
with close to 24.00 mg/l (99,29%), and COD started to be effectively reduced on day
20 (T 2) with close to 44,65 mg/l (98,90%) due to the levels were already below the
value of the Quality Standard Liquid Waste (QSLW). Generally, time retention was
best accomplished on day 30 (T 3) in reducing liquid waste rubber industry.
