Abstract

Observation of water quality i.e. physics, chemistry and biology, nitrate and phosphate,abundance of plankton, social economy of society around oxbow lake to quality water ofoxbow lake. Was conducted in oxbow lake village of Buluh Cina to know water quality of thelake from February to April 2013.The water quality of physics and chemistry in the waters of oxbow lake of Buluh Cina villagewere found that: the depth range 239,5 to 442 cm, the temperature ranged from 29 to 30,4 0C,the brightness ranged from 68 to 95,5 cm, turbidity ranged from 5 to 6,2 NTU, pH rangedfrom 6,01 to 7.65, carbondioksida ranged from 6,75 sampai 7,25 mg/l, dissolved oxygenranged from 5,2 to 6.9 mg/l, nitrate ranged from 0.06 to 0.08 mg/l, phosphate ranged from0.01 to 0.05 mg/l. Obtained the species and abundance of plankton as many as 29 species in8 class with abundance ranged (12.180 to 15780 sel/ l), of the value of diversity index (H ')ranged (4,2773 to 4,6488), the value of the diversity index (E') ranged (from 0.8805 to0.9569), and the dominance index (C ') ranged (0.0467 to 0.0679). the spesies and abundacemakrozoobenthos as many as 7 spesies in 4 class, abundance ranged from 125 to 174 ind/m2.of the value of diversity index (H ') ranged (2,1694 to 2,6908), the value of the diversity index(E') ranged (from 0.8392 to 0.9585), and the dominance index (C ') ranged (0.1658 to0.2617). In general, waters quality condition of oxbow lake Village of Buluh Cina is still ingood condition and support for living organisms, Activities of society not yet influencesignifican to quality condition water.
