Environmental degradation occurs from upstream to downstream of Bengawan Solo river. One of the things that makes the quality of the Bengawan Solo river decrease is waste pollution. The waste is both domestic waste originating from household activities and also industrial waste, both small and large scale.
One of the locations of Bengawan Solo river pollution is the textile industry in Laban Village, Mojolaban sub-district, Sukoharjo Regency. The textile industry in Laban village is communal or in groups, so that the areas are close to each other and have one waste disposal channel.
Textile industry activities in Laban Village, Mojolaban District are dyeing fabrics to become jumput fabrics or beach fabrics.
