Abstract
This study aims to analyze the study of the effect of improvement of water quality
parameters of peat water with filter system, biological coogulation and microalgae for fish
farming activities. The research was conducted in Sungai Tohor Village, Tebing Tinggi
Timur Subdistrict, Meranti Islands Regency.
Procedure of research activity is done by way of peat water coming from canal pumped by
multilevel filtering. Water filtration by drum stratum is intended with macro and micro
filtration separation, macro filtering using only ijuk and burlap sack. While microscreening
using layers of krikil, sand and charcoal, and the provision of lime tohor.
The results showed that there was a change (increase) to pH value from 3.7 to 5.4;
Dissolved CO2 decreased from 31.9 to 24.6 mg /l, dissolved DO increased from 3.92 to
4.09 mg /l, TSS decreased from 82.5 to 4.5 mg /l, increased brightness from 64.5 to 68.2
cm and the temperature rises from 27.9 to 30.1 °C and there is growth and multiplication
of microalgae on the surface of water. From the experimental maintenance of catfish
dumbo done, generally not possible to survive, because the still high dissolved CO2 which
is toxic to fish and pH that still needs to be improved again. Need further research on the
technique of reducing the dissolved CO2 value and increasing the pH value, thus reaching
the recommended threshold point for fish farming. For fish cultivation activities from the
results of this study only allows to cultivate the local fishes only.
