ABSTRACT
Hadi Prayitno. 2006. THE EFFECT OF LIQUID TEXTILE WASTE SUPPLY
OF PT. BATIK KERIS SUKOHARJO ON THE CHANGE OF
TEMPERATURE, pH, DO, BOD, NO3, Ca, Mg, AND PLANKTON IN THE
PREMULUNG RIVER SURAKARTA. Biology Departement. FMIPA. UNS.
Surakarta.
PT. Batik Keris Sukoharjo is a textile manufacture with batik as a motif, it
is located in Cemani villages, Grogol, Sukoharjo, Central of Java. This
manufacture disposed continuously the liquid industrial waste into the canal,
which is supplies water to the Premulung river in Surakarta. The aims of this
research were to know the quality of the liquid textile waste canal of PT. Batik
Keris Sukoharjo, and how the effect to the conditions of Premulung river, based
on temperature, pH, DO, BOD, NO3, Ca, Mg and diversity index of plankton.
The water samples are taken from the rivers by using a range methods
(plotless sampling methods), by dividing the river into 5 (five) monitoring stations
with the distance of its station is ± 50 metre and done by 3 (three) repetitions, that
is on the left of the river-bank, middle, and on the right of the river-bank. Data
were analyzed by using descriptive analysis.
The result of the research indicate: (1) Quality of the liquid waste textile in
the waste canal of the PT Batik Keris Sukoharjo based on parameters for
temperature, BOD, NO3 is exceeding maximum boundary and DO that is below
from minimum boundary, and based on the diversity index of plankton is classify
to the moderate pollution, (2) Liquid waste textile supplies of PT. Batik Keris
Sukoharjo do not show the signifikan influence to the change of temperature, pH,
DO, BOD, NO3, Ca, Mg and diversity index of plankton of Premulung river
