| dc.description.abstract | Upstream cultivation activities by use intensive fertilization have an impact on water quality
degradation. Accumulation within several decades will cause damage to the hydrological conditions the
watershed. Residual substances and heavy metals due to intensive fertilization will affect the biotic and
abiotic components of the watershed ecosystem. Water in Indonesia is divided into several classes,
namely class I, II, III and IV. Every class has a quality standard according to its designation class. This
study aimed at evaluating the status of water quality based on physical and chemical parameters in the
upstream area (rainfall catchment). Water sampling was carried out at three points, namely water sources
(in), locations of aquaculture activities (irrigation), and rivers (out). Chemical parameter results showed
that DO was 7.16 mgO
2
/ L in the river (out), BOD was 7.84 mg/L in irrigation, COD in the river was
25,50 mg/L, the irrigation point nitrate was 6.75 mg/L, and pH average was 6.80 almost at each sample
point. As for the physical parameters consisting of colour, smell, and temperature. The physical
parameters based on Government Regulation No. 82/2001 were still in accordance with the specified
quality standards. Management through monitoring river water quality requires an integrated model as an
effort to conserve water resources. Result Rapid Rural Appraisal in the upstream area of the Bedadung
Jember watershed showed that the role of institutions at the farm level was less than optimal.
Communication between farmers level, agricultural extension workers, and several stakeholders was not
good. Meanwhile, the participation of the community and several stakeholders had an important role as
users of natural resources in conservation. | en_US |
