Biodiversity of wetlands in Tabukan District South Kalimantan Province is very large. One of them is weeds which locally named Purun Tikus (Eleocharis dulcis). Previous study showed that the potential purun in Muara Pulau Village Tabukan District was about 9450 m2. However, the income gained by the forest community was considered very low. This step of study activities were to set up added value so that the community could gain more income from purun. Application of technology, through coloring and stabilator treatment, and helping in marketing, brought significant increasing of income. Utilization of purun could also reduce the plant population. The next study would search the potency of purun to absorb toxic elements in wetlands and rice lowlands. It is expected that this research results could be applied in other purun areas.
