Water temperature of Ciambulawung River is ranging from 22 to 26°C and it was considered in good condition.
Moreover, it describes the natural condition of the surrounding mountains [4].Temperature is basically important for
its effects on certain chemical and biological reactions taking place in water and aquatic organisms [5].
Temperature altered by the change of the sampling time. The interval of sampling time was one month. This can
be due to the differences of weather, humidity, and sunlight exposure. At first sampling, the bright weather affected
the temperature. Government Regulation (GR) No. 82/2001 (class II) defines temperature deviation of 3ºC. Hence,
the temperatures of water at three stations still meet the national quality standard.
Turbidity of water in the surrounding mountains or upper part river is denoted a very low compared to the
downstream river. Turbidity is derived from suspended materials such as mud, sand, organic and inorganic materials,
plankton and other microscopic organisms. The turbidity of the water in the upper part of Ciambulawung River
ranged 1.5 - 3.7 NTU. Turbidity of upper part of the river normally quite low was also reported [6].
Highest turbidity was at the station 2, since the dominant sediment of station 2 originates from sandy mud of the
river bottom. The station 2 was also often used for washing motorcycle, clothing, and washing muddy agricultural
tools by the farmers. High turbidity affects aquatic life [7].
