Herbaceous Plant Community Structure Around The Waste Ponds of PT. KSL in Betung District, Banyuasin Regency, South Sumatra
- KSL was a company in the palm oil processing and the palm nursery inLubuk Karet of Betung District, Banyuasin Regency, South Sumatra which had the ponds to accommodate the residualwaste water of the treatments. Around the edges of the ponds there were a lot of the herbaceous plants that were cleared routinely. The clearing land would affect the community structure of the herbaceous plants. Thus, this research aimed to determine the herbaceous plant community structure around the company’s waste ponds. The research method used was purposive sampling with 15 observation plots which was each measuring 2m x 2m. The herbaceous plant community structure was analyzed using Shannon-Wiener diversity index and importance values by counting the number of species and individuals of each species. The result research showed that the diversity of the herbaceous plants around the waste ponds was low (1.16 to 1.75), except the plot 8 which had a very low diversity index (0,90). The highest importance value in the herbaceous community was Asystasia gangetica (37.24%). It showed that Asystasia gangetica was the herbaceous plant that dominated. The dominating species meant having the wider range than the other species to the environmental factors.
